[U-Boot] [PATCH] ppc: xilinx: Remove ancient ppc405 and ppc440 platform

[Ricardo Ribalda Delgado]

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
