[U-Boot-Users] [PATCH] Support fot the ML507 Board 1/4

[Ricardo]

Hi List:

 This is my first contribution to u-boot. I have ported u-boot to the
ML507 Board by Xilinx.
http://www.xilinx.com/products/devkits/HW-V5-ML507-UNI-G.htm

This boards includes an FPGA Virtex 5 FX with an embedded PowerPC 440.

The port supports:
    -Virtex 5 ppc440x5
    -XIlinx Interrupt Controller
    -Xilinx I2C Controller (Interrupted mode)
    -Xilinx Uart Lite (simple port)
    -Xilinx LL_TEMA (Interrupted and SGDMA)
    -Save environment on board eeprom
    -DTT support for the ADT sensor on board (new hwmon driver)
    -Dummy I2C driver (for testing purposes)

This patch works against the last commit to the p4xx branch.

I am a researcher of the Universidad Autonoma de Madrid, and this work
has been supported by Q-Technology ( http://qtec.com ) under a
Research Agreement.

Any comment will be very welcomed.

PS: I have divided the patch in four parts for the mailing list

Hello Wolfgang

  I wanted the four parts to have the same subject, to easy the
handling of the files. The first submition was 4 .bz2 dependent
files... But later on the evening I have prepared 8 different
INdependent patches following the guidelines on the u-boot site. Sorry
for the mess. I have sent some minutes ago an apologize and a
explanation. Please check it if you have enough time. It is my first
time with git, and I am a bit confused (even after a day of reading)


 Best regards and thanks

But this makes no sense, especiall when you add "1/4" to the subject.

The guidelines say:

	...
	Separate _logical changes_ into a single patch file.

	...
	No MIME, no links, no compression, no attachments.  Just plain
	text.

	...
	The canonical patch subject line is:

[Michal Simek]

Hi Ricardo,

I read your patches in your weird style. 
These style of patches never go to mainline. You use xilinx generated files which is currently use only with ml300.
For example look at your xparameters.h there are a lot of values which are not used.
If you want to add ml507 to mainline U-BOOT you have to change completely handling style of xilinx board for ppc.
In next U-BOOT release I will clean ancient ml300. I want to remove a lot of xilinx generic files.

100% NACK for these patches.

The size of patches is due to your incorrect design strategy.

Hi List:

 This is my first contribution to u-boot. I have ported u-boot to the
ML507 Board by Xilinx.
http://www.xilinx.com/products/devkits/HW-V5-ML507-UNI-G.htm

This boards includes an FPGA Virtex 5 FX with an embedded PowerPC 440.

The port supports:
    -Virtex 5 ppc440x5
    -XIlinx Interrupt Controller
    -Xilinx I2C Controller (Interrupted mode)
    -Xilinx Uart Lite (simple port)
    -Xilinx LL_TEMA (Interrupted and SGDMA)
    -Save environment on board eeprom
    -DTT support for the ADT sensor on board (new hwmon driver)
    -Dummy I2C driver (for testing purposes)

This patch works against the last commit to the p4xx branch.

I am a researcher of the Universidad Autonoma de Madrid, and this work
has been supported by Q-Technology ( http://qtec.com ) under a
Research Agreement.

Any comment will be very welcomed.

PS: I have divided the patch in four parts for the mailing list

[Ricardo]

Hi Michael

  Sorry to hear that. I have tried to give all my best and follow the
style of the ml300 board, which was the closest board to mine.
On FPGAs board I think that it is not  a horrible idea to follow this
style. Maybe you should consider to create an FPGA branch, where the
generic drivers could be accepted. As I said, the FPGA hardware
changes a lot and support a so changing hardware will be very
difficult... Or just should not support FPGAs and its IP devices...


By the way:

  patches 1 2  and 6 follow the guidelines and don't add any generic driver
  patches 8 (except xparameters.h) follow the guidelines
  patch 6 could be redesined. You should be aware that
driver/serial/serial_xuartlite.c does not compile for ppc440 without
that patch


  Best regards

Believe me, this makes no sense. Copying the same files around quickly
results in an unmaintainable mess. Adding lots of code which are not
actually needed just prevent anybody from actually understanding which
code is essential and which not.

We've been there before, and we learned this lesson.

I do not think that FPGA have any inherent  problems.  The  issue  is
with  the  base  code  which  was  not written with a boot loader (or
portability and efficiency) in mind.

[U-Boot-Users] [PATCH] Support fot the ML507 Board 1/4

[Ricardo]

Hello Wolfgang

  Lets find a solution to support ML507 on u-boot (and make my work
availiable to more people). I am completly with you about the low
quality of the xilinx-adapted code. I am using it for two things: i2c
and ethernet, but the board can perfetly work without them.  The i2c
code can be very simply adapted to the "good way".

  Tomorrow I will work on a patch for the CPU, ADT7640, Uart Lite and
the board without i2c and in the near future I will provide a "clean"
driver for the xilinx i2c.

  How does it sounds for you?


       Best regards

Any FPGA branch is not acceptable in U-BOOT mainline. Mainline U-BOOT is only
one. If you want to add your changes to U-BOOT mainline you have to change your
design style.

This should be truth but without compatible board doesn't make sense to me. You
use any numbers but I haven't seen these numbers anywhere. Please use git for
your work and use more generic subject of your email. In set of patches you use
conventional style which generate git. Add there at the begging ml507 or xilinx
or whatever what will be specify xilinx relate topic.
