Hi Ricardo,

Yes, simple ifdef CONFIG_XILINX_LL_TEMAC in config file is sufficient.

Yes, but FPGA is different case. Arm boards can't be change by user to much as
you can change FPGA boards. First u-boot compilation on this board will run.

Please Wolfgang for some comments but IMHO this is not the point support a lot
of boards as is possible. 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.

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.

ok. And rename config files too.

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.

no.

the same style as is used in Microblaze config file - look at ml401 or xupv2p
config files.

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.
