[U-Boot-Users] [PATCH] cpu/ppc4xx/sdram.c

[Stefan Roese]

SYLee!

I checked a rewritten version of this code in yesterday! Please take a
look at the version from the current cvs tree.

By the way: I am still pretty sure that the old version is OK! Did you
experience any problems with it?

Best regards,
Stefan Roese
