This patchset contains the support for 4 SoCs from SPEAr family
SPEAr300
SPEAr310
SPEAr320
SPEAr600
It also contains the drivers needed for spear devices
Regards
Vipin Kumar
Vipin (9):
i2c driver support for SPEAr SoCs

The changes to board/* should be moved out of this patch and into patch
9 "SPEAr600 build support added". Same comment for
include/configs/spear600.h.

It'd also be nice to give a description of each board and SOC you add.
Eg what's the difference between the 300, 310, 320, 600? What
peripherals do they support? What does SPEAr stand for? More commit
messages in general wouldn't hurt:)
Best,
Peter

SPEAr (Structured Processor Enhanced Architecture).
You can find some description throughout Internet, for example here:
http://embedded-system.net/spear-basic-customizable-arm-based-soc-stmicroelectronics.html
(SPEARBasic means SPEAr300.)
As you can see this SoC family embeds a customizable logic that could
be programmed one-time by a customer at silicon mask level (i.e. not at
runtime!).
We are now adding the support in u-boot for two SoC: SPEAr600 and SPEAr3xx.
Pls note that SPEAr300/310/320 differs only for the default customization.
All 4 SoCs share common peripherals.
1. ARM926ejs core based (sp600 has two AMP cores, the 2nd handled only
in Linux)
2. FastEthernet (sp600 has Gbit version, but same controller - GMAC)
3. USB Host
4. USB Device
5. NAND controller (FSMC)
6. Serial NOR ctrl
7. I2C
8. SPI
9. CLCD
10. others ..
sp600 is not customized by default.
sp3xx are differently customized...
sp300 is more oriented to TELECOM/video (it has tdm, i2s, ITU i/f support)
sp310 for networking (a part GMAC in fixed part, it has 5 MACB ctrls in
custom)
sp320 for industrial (SPP ctrl, CAN ctrl, 2 MACBs, ...)
Everything is supported in Linux.
u-boot is not currently supporting all peripeharls (just a few).
Regards,
Arm

I see. It'd be nice to put some of the above information in the U-Boot
commit logs to give people an idea about what's going on without having
to use google, etc.
I haven't looked at the code differences between the sp3xx boards, but
you might be able to use 1 common board file/header file to support them
all. For example, take a look at the M5475AFE_config rule in
U-Boot's ./Makefile. Some extra code in the Makefile and some #ifdefs
in the sp3xx code might accommodate all 3 boards.
Best,
Peter

Your patch order is, um, sub-optimal.
You start adding an I2C driver for a non-existing CPU here.
This makes no sense, please reorder.

It seems you can move the lines
writel(cntl, &i2c_regs_p->ic_con);
i2c_setfreq(MIN_FS_SCL_HIGHTIME, MIN_FS_SCL_LOWTIME);
out of the if/else blocks and make them common code.

It makes no sense to run "readl(&i2c_regs_p->ic_con)" six times - run
it once and latch the value.
Also I tend to think the logic can be written clearer.

This shares a _lot_ of common code with i2c_read() - factor out?

Please split into two patches: one with generic usbd driver, and the
second adding support for SPEAr.

This looks wrong. Should that be a "#ifndef DEBUG" instead of "#if 1"?
And cannot we use standard debug facilities?

Now her eit becomes clearly SPEAr-specific. Should this not be split

NAK.
Please do not enforce such a policy on all your users. Let them
decide if they want this, or not.

Do we need a new custom command for this? Either allow setting by
environment variable only ("cpuclk" is already used by a number of
systems), or use a common command name ("chip_config" was chosen for
this after some discussion a while ago).
Also, is no further checking needed? Can I set arbitrary frequencies,
like 307 for CPU and 277 for DDR?

Again: you seem to be adding just a new board, not a new SoC - please
fix commit message.
See review comments for previous patch; they all apply here, too.

This patch must be merged with the one adding the actual code for this
board.

...and even better in some doc/README.??? so it is part of the source
code.

Extra code in the Makefile should not be needed any more.

Zero is an enigmatic value. It can mean success (fclose) or failure
(scanf). It can mean black or white. It can mean no permissions
(chmod) or all permissions (umask). It can mean now (setjmp) or later
(atexit). It can mean the beginning (lseek) or the end (read). It can
mean myself (getpgrp) or child (fork). It can mean all (kill's 1st
argument) or nothing (kill's 2nd argument). It can mean `default'
(SIG_IGN) or `I don't care' (waitpid) or `try to guess' (strtol).
Indeed 0 lets you talk to God (setuid).
Verily is 0 all things to all people.

To be clear, you still think its a good idea to look into combining the
similar boards, correct? I haven't dealt with the MKCONFIG voodoo, so
maybe I chose a poor example. Perhaps the CPCI405 and friends is a
better example?
Best,
Peter

Currently supported flashes have consequent values of density.
It may have random values supported in future. That's the reason

We also use u-boot as a firmware which runs on the board in a special
mode in which the firmware fetches and burns images into
NOR/NAND flashes. Under this mode, we would like to always jump to
u-boot prompt.
Also, the bootdelay variable should remain unchanged as we save default
environment variables as well.

Ok, changed to #ifndef DEBUG
The standard debug facilities use printf and we also test and use this for
usbtty feature. So, a serial_printf is required

SPEAr310 is a new SoC but it has a lot in common with SPEAr300
Offcourse, since only the common IP's are supported in uboot, there
is no new driver required for SPEAr310.

That's why I did not recommend to calculate this witha simple
formula, (which would be trivially possible for "size", but not so
for "sector_count"), but using a lookup table - this is independent
of the actual values.

Why don;t you protect sectors where the U-Bootimage and environment
are stored?

This can be done by plain config settings. No need to chang ethe code.

Think of a different way to switch modes, please. I don't accept this

Some parts of the code rely on this. It has been a bad idea to ever
make this a config variable (but that's history, and we cannot change
it).

Since the code is being developed for a development board, erasing and
flashing the uboot is frequent. This is done only to save unprotect every
time before erasing/flashing uboot

You could protect the sectors and then have a script in the default
environment that automates unprotecting as well as erasing, loading new
u-boot and flashing. This way you get the best of both worlds,
protection against accidental erasures and simplicity of reflashing.

I didn't get this. I want the uboot behavior as if bootdelay is set to -1.
And offcourse without changing bootdelay. I could not get if this can be
done by any plain config setting
Please let me know if I am missing something

Source modified to
if (ethaddr from environment fails)
read mac from i2c memory
This should be ok. Right

Code modified to use chip_config. this command is implemented in board
specific file. I guess that should be ok since there is no standard interface
for the command

Yes, all values below 333 are acceptable. This command is added for testing
purposes only so no further checking is required

Ok. But then bdinfo should ideally contain a generic callback
to be implemented by board specific code.

That's what I expected. Please do add proper protection, so that
everybody who copies the code for a real production board has a sane
implementation.
If you are worried about having to type too many commands for update,
please consider pre-defining useful macros like we do in so many other
boards; for example:
"include/configs/aria.h":
"u-boot=aria/u-boot.bin\0"
...
"load=tftp ${u-boot_addr_r} ${u-boot}\0"
...
"update=protect off ${u-boot_addr} +${filesize};" \
"era ${u-boot_addr} +${filesize};" \
"cp.b ${u-boot_addr_r} ${u-boot_addr} ${filesize}\0"
so you only have to type "run load update".
Best regards,
Wolfgang Denk

There's an extra space before '=' here.
