PATCH 1/1 ppc: xilinx: Remove ancient ppc405 and ppc440 platform

Hello Michal and Stefan

Could you provide some context about why are we removing this? Virtex 5 (and V4) are not yet in their end of life.

The plan is to re-factor the code for this platform or just drop all the support?

There are also yocto layers that support ml507 and ml405
http://git.yoctoproject.org/cgit/cgit.cgi/meta-xilinx-community/tree/conf/machine

The xilinx git tree still supports this boards, will you also remove support there?

Regards!

Hi,

Hello Michal and Stefan

Could you provide some context about why are we removing this? Virtex 5 (and V4) are not yet in their end of life.

I was checking this internally and ppc is not supported by tools for several releases (roughly ~2 years). All support from tools was already removed.
There is no testing on it done for a long time that's why this platform is obsolete from my point of view.

Platform needs to be moved to generic board support and none from xilinx will do it. If you want to invest your time and support these boards feel free to do it but from my perspective we should just remove it because it is just old and make no sense to waste our time on it.

I am not yocto guy but from cgit it looks like that it is pretty old too. ppc support 4 years ago, ml507 2 years ago.

I am following mainline. It means removing board in mainline is resulting removing the board in xilinx trees.

Thanks,

Virtex5 is only supported by ise/edk, not vivado. This is why the tools from the last two years does not support ppc.

I think that the position from xilinx was to support ise for as long as v5, s6... was on sale.

We still use it actively on the fpga family of our productsm and cisco uses quite a lot of virtex5 :)

Also avnet virtex5 boards are still available

If the patch can wait a bit before it is merged it will be great.

I will wait to see if you (or someone else) wants to step up and maintain it.

Anyway this is Virtex5 - ppc440. Any intention to keep ppc405 alive?

PATCH 1/1 ppc: xilinx: Remove ancient ppc405 and ppc440 platform

Hello

I have followed doc/README.generic-board and simply adding CONFIG_SYS_GENERIC_BOARD does the trick.

So far it has build with no warnings for:

ml507
ml507_flash
xilinx-ppc440-generic
v5fx30teval

and I have run it on the ml507 with no issues (is the only hw I have with me this week, but it is VERY similar to the others):

Simply adding CONFIG_SYS_GENERIC_BOARD to the .h file works perfectly As you can see from here:

U-Boot 2015.07-rc1-00091-g698a12bef9e7-dirty (May 12 2015 - 10:14:15)

CPU: IBM PowerPC 440x5 VIRTEX5 at 400 MHz (PLB=100 OPB=8 EBC=67)
32 KiB I-Cache 32 KiB D-Cache

DRAM:  256 MiB
Flash: 32 MiB

*** Warning - bad CRC, using default environment

U-Boot is up and runnining
ml507:/#

Regarding xilinx-ppc404 and fx12mm

It also builds ok, but I have no access to an fx12mm. Perhaps Georg can give it a try to confirm that this still works.

Is there any other test that needs to be done after "porting" them to generic board?

Thanks

So I was about to send another email but then I dug a bit further and see you're already listed as the maintainer for all of these platforms. So the question comes back to you, is there anything else you'd want to test before declaring things OK? This particular change is indeed easy but there's other stuff that'll need doing soon enough (device model releated things), so please read up on that. Thanks!
