On ppc, a common object consist on u-boot on the begining of the memory and a jump and tlb setup on the last part of the memory (0xfffffffe). If the gap is included, u-boot can produce a 4 Gigabyte object!, with no more info that the srec. On the other hand, it cant be avoided in the .bin object. It has no information about memory location.

* [U-Boot] [PATCH] ppc440: New board: Avnet Virtex5 FXT Evaluation 2008-08-22 16:35 ` [U-Boot] [PATCH] ppc440: New board: Avnet Virtex5 FXT Evaluation Ricardo Ribalda Delgado @ 2008-08-23 19:05 ` Michal Simek 2008-08-24 0:42 ` Ricardo Ribalda Delgado 0 siblings, 1 reply; 16+ messages in thread From: Michal Simek @ 2008-08-23 19:05 UTC (permalink / raw) To: u-boot Hi Ricardo, Stefan and Wolfgang, I looked at patches which Ricardo sent. It is really nice to see that someone wants to add new xilinx boards to U-BOOT. But IMHO this is not the right way. I think that one xilinx board with ppc405 and ppc440 is enough. This is FPGA you can choose almost everything what you want to change. -> It is useless add new board which has only different setting. It doesn't matter if is avnet or xilinx board and they have different size of flash, ram or whatever. I think that the right way is to have one generic platform and your xparameters can direct it. With adding new board you see avnet board in board folder but that's all. Setting is almost the same with ml507. Please do not extend U-BOOT code with boards which do not add important change. I hope you understand what I mean. The next reason should be what is avnet reference design? (You can use some edk version with ppc440 and there are some changes between version) In Microblaze case you can see I add only two boards - one is with flash and second without. I can do thousands design with different setting but this is not good solution. Please do not add this board and do not start new way that every fpga board will have own folder and config file. This only extend U-BOOT size and that's all. No additional information. My propose solution is to have one generic board (ml507 is ok) and improve ml507 config file for usage with others board. This is what wrote Wolfgang in emails about ml507. Do not hardcode value in memory settings and other.

* [U-Boot] [PATCH] ppc440: New board: Avnet Virtex5 FXT Evaluation 2008-08-23 19:05 ` Michal Simek @ 2008-08-24 0:42 ` Ricardo Ribalda Delgado 2008-08-24 9:49 ` Michal Simek 0 siblings, 1 reply; 16+ messages in thread From: Ricardo Ribalda Delgado @ 2008-08-24 0:42 UTC (permalink / raw) To: u-boot Hello Michal I agree with you that the code of ml507 and other board with that fpga will be almost the same, except external devices like ram, flash type ethernet macs.... But the same happens in other part of the code: many arm boards are very similar between them, etc. In the other hand is very convenent (and commercial) that u-boot support as many boards as possible, support explicitily, not as part of a common board, think that the boards are organized by vendor: User are not supported to know all the manufactures "excentrities" I have been thinking a bit about this and I came with this idea (please give me your comments): - Create a folder like: /board/xilinx/generic/ppc440 /board/xilinx/generic/ppc405 /board/xilinx/generic/microblace - Create one config for every previous generic board (nothing new until know) - Create one config file for every specific board that includes the generic configuration for it class - Create folders like /board/xilinx/ml507 with the specific ml507 code (99,9999% this wont be needed) The generic configuration will take care of the xparameter file: something like: #if XPAR_TEMAC #define CMD_NET_PING #endif Using this philosophy, there is no code replication, boards are explicitly supported and future boards with rare features will be also supported easily Any ideas/sugestion?

* [U-Boot] [PATCH] ppc440: New board: Avnet Virtex5 FXT Evaluation 2008-08-24 0:42 ` Ricardo Ribalda Delgado @ 2008-08-24 9:49 ` Michal Simek 2008-08-25 8:09 ` Stefan Roese 0 siblings, 1 reply; 16+ messages in thread From: Michal Simek @ 2008-08-24 9:49 UTC (permalink / raw) To: u-boot Hi Ricardo, > Hello Michal > > I agree with you that the code of ml507 and other board with that > fpga will be almost the same, except external devices like ram, flash > type ethernet macs.... Yes, simple ifdef CONFIG_XILINX_LL_TEMAC in config file is sufficient. > But the same happens in other part of the code: many arm boards are > very similar between them, etc. Yes, but FPGA is different case. Arm boards can't be change by user to much as you can change FPGA boards.

I think that the point is support important boards in every category and every new board should add any information to U-BOOT. If the manufacturer has the board with name (arm, ppc) and this board is distributed and known by this name it is good reason to add this board to U-BOOT. For example all freescale boards are good example. A lot of company just copy their hw design - change some minor parameters and do it as proprietary board. > > I have been thinking a bit about this and I came with this idea > (please give me your comments): > > - Create a folder like: /board/xilinx/generic/ppc440 > /board/xilinx/generic/ppc405 /board/xilinx/generic/microblace board/xilinx/ppc440 and ... is sufficient. Just renaming folder should be sufficient. For microblaze case -> xilinx/m401 -> xilinx/microblaze For ppc405 -> xilinx/ml300 -> xilinx/ppc405 For ppc440 -> xilinx/ml507 -> xilinx/ppc440 And remove others folder in xilinx directory. > - Create one config for every previous generic board (nothing new until know) ok. And rename config files too. > - Create one config file for every specific board that includes the > generic configuration for it class No. I think that one generic config file is sufficient. Because if you are able to compile and run U-BOOT with using generic config on every board with MB, ppc405, ppc440 (of course with specific config files for every platform), you know that your work is functional. You can use it on every board based on your generic board. I do the same for Microblaze - I use some platform and tens design (every design is different) but everything is based on generic design. My U-BOOT bsp can handle a lot of peripherals and generate proper parameters for every board and I see that my generic config file cover all possibilities which can come. If this generic file failed I see that something is wrong there and it is the right time to fix it. My approach is just rename folder to generic style as you suggested. And write one simple readme file where you can write step by step manual how to configure u-boot and then ml507 ,reference design from xilinx page - edk version was tested and works. Avnet virtex5fxt tested, etc... I think this is solution. > - Create folders like /board/xilinx/ml507 with the specific ml507 > code (99,9999% this wont be needed) no. > The generic configuration will take care of the xparameter file: > something like: > > #if XPAR_TEMAC > #define CMD_NET_PING > #endif the same style as is used in Microblaze config file - look at ml401 or xupv2p config files. > Using this philosophy, there is no code replication, boards are > explicitly supported and future boards with rare features will be also > supported easily > > Any ideas/sugestion? I see code duplication in main Makefile. This Makefile is long and I haven't seen why we should this file do longer then is. As I wrote one generic board is enough with two choices as you add for ml507 - w/flash and wo/flash choices. The next information which is useless is in a lot of xparameters files in u-boot. What does it happen in this case that newbie buy a new board? Newbie look at manufacturer pages and look at demo which is in box. Starting to play with linux (or whatever) and find that needs a bootloader. Look at google and find u-boot. In your case newbie find supported board and see that his board is on the list or not. if (is on list) { Newbie straightaway download u-boot and compile it for their platform and I think in 98% first attempt to load u-boot failed because he did small change in his design. Newbie will not happy and start to send email that u-boot doesn't work for his platform and the name is the same as is in u-boot } else { if(not lazy) { look at similar board and try to find if is possible to change current board and run u-boot on the board } else { Look at google and try to find out if someone run u-boot on his board and some cases he started to write his own bootloader. } } In generic case. Find that U-BOOT support generic boards. Every newbie know what word generic means. Find maybe in doc folder his case or will see warning message that on this file in doc folder is described that only change xparameters file is enought for run u-boot on his platform. Simple step by step manual. He do some steps (I think 3 step should be enough) and load u-boot to his platform and run it. And if generic file cover most of possibilities u-boot will run. And then just look how to add his own platform to u-boot and in his private repo will do folder with names which he choose.

I'm not so sure if those FPGA based boards are this different from the "standard" boards with SoC's, like PPC's ARM's etc (please correct me if I'm wrong). You will most likely also have board specific implementation differences like: - different SDRAM configuration (non-SPD vs. SPD) - different PHY's and PHY addresses - different FLASH configuration that can't be handled with one CFI option set - etc.. So it makes perfact sense for me to "allow" multiple board ports in the official U-Boot repository for the Virtex 440 for example. Again, please correct me if I am wrong here. > > In the other hand is very convenent > > (and commercial) that u-boot support as many boards as possible, > > support explicitily, not as part of a common board, think that the > > boards are organized by vendor: User are not supported to know all the > > manufactures "excentrities" > > Please Wolfgang for some comments but IMHO this is not the point support a > lot of boards as is possible.

This sounds too good to be true. But how do you handle those cases I stated above? You will need at least different config options. And then you have to use multiple #ifdef's in the generic config header. I prefer the approach from Ricardo here. > My approach is just rename folder to generic style as you suggested.

Again, I think Ricardo's approach with the common board directory is a good idea. And I still think that we should add as many boards as possible to the official repository. There are already too many boards using U-Boot which are *not* available here and that's a shame from my point of view.

I think that in this state which we have - only two ethernet cores are in U-BOOT and one of them is ancient and use by older boards and emaclite doesn't care about phy, it is not right time to care about phy. Phy lib is not in U-BOOT but for example in Yoshio ll_temac driver is use phy detection.

There are already too many boards using U-Boot which are > *not* available here and that's a shame from my point of view. I agree with you that U-BOOT runs on many boards and in many case is shame that they are not in U-BOOT repo but the question is if the information value from this board add any information to U-BOOT code. Many of these boards are proprietary boards. Others then use generic platform and hw developers just change phy or use switch on board. I agree that if someone use for example new Vitesse switch and there is difficult initialization is a big shame that this board is not in U-BOOT repo. But I think that others "boring" board with just change size of memory, flash and others minor things should be out of u-boot. FPGA cpu are different. You have to use EDK for creating your design. You have one board and you can do in Microblaze case almost everything (ppc board has more limitation) and you can have tens (thousands) designs which are interesting. That what I want to see that what is reference design. Of course you can't add more memory which is on development board and others thing but in every case you do your design yourself you have to use any generator for extract parameters from your design. That is what Ricardo, I and other use because we have to. Xparameters is that file. (You can see it in xilinx folder). You have to generate this file and values in this file describe design in detail (not every possible choices are covered). I use for Microblaze generator which I had and I haven't found any problem which should not be covered by bsp directly from EDK. Microblaze community use a lot Petalinux. There is ancient U-BOOT version and there is used only one file for every board which are in full distribution. This is really what people use and they just compile one generic board. IMHO if this approach works on microblaze that this approach should work on ppc440 too. You can look at ml401 and xupv2p config file. There is big overlap just because one board hasn't flash memory but in ml401 is handled both. I have improved configs in my repo which I used with some others feature and they are not in U-BOOT mainline because of time.

Yes, we will need board directory for proprietary solution. Look at my first email I wrote about. Of course if you do your project you should create some directories only for you. But I think we don't need special folder for reference design and board. Your STRANGE_BOARD_USED_ONCE choice is due to you use something strange which should not go to mainline U-BOOT. I don't like strange things. If is something strange you have to find out why. Just writing strange is more stranger for others which will read your code. Please add more choices which you need in your config. Memory, flash, iic, spi, watchdog, dtc, maybe gpio - but this is not important dcr reading, systemace, ethernet controllers, uarts I see maybe 20 ifdef choices not more right now.

This is not correct. The U-Boot image does not occupy any low memory - low memory is reserved for RAM, while the U-Boot image is stored in ROM. ROM is typically mapped in high memory, often close to the end of the physical address space. > If the gap is included, u-boot can produce a 4 Gigabyte object!, with no > more info that the srec. Incorrect again. The U-Boot image never exceeds the physical size of the ROM. Typically the U-Boot image size is well below 256 KiB, with few systems (which include graphics support and other complex stuff) going up to 512 KiB. > On the other hand, it cant be avoided in the .bin object.

I have a design with this memory map: 0-128 MB -> RAM 128-192 MB-> ROM Last 32 KB BRAM (initialized ram) It is not a typical design, but it is possible. In this case u-boot will be located in the last bram and in the rom, with gap fill U-biit srec will be huge. Again: It is not a typical design! > I think your patch makes sense and could be applied, but the commit > message is too incorrect. Please fix this and resubmit.
