Cover letter [U-Boot-Users] [PATCH 0/2] PPC4xx: Make LWMON5 ECC POST board-independent
Hi Stefan (and group),
Here for your comments and suggestions are my proposed patches to take the ECC POST for the LWMON5 board and generalize it to all 440EPx/GRx boards. This code is running on our prototype Korat 440EPx boards.
I have replaced the volatile pointers with calls to in_be32() and out_be32(), but the synchronization between the writes creating the ECC errors and the reads to detect them is still required. I have left these changes in as I feel the code is clearer with them.
Please note that these patches require my previous patch to "include/ppc440.h".
Best regards,
Larry Johnson
