[U-Boot-Users] RE: u-boot patches for BUBINGA

[Bruce Boettjer]

Bill,

Great job with the coding!  U-boot came up on the first build(with your
patches), with no mods <BUBINGA405EP>.

Just a quick note... The memory config on the 405EP Eval board is still
incorrect.  The Physical DIMM is 64-bit, but the memory bus is 32-bit...
therefore, only half of the memory gets used...

In spd_sdram.c, I added a line after 354 that divided 'total_size' by two.
This appears to do the init correctly.

BTW-Is anyone able to get a uImage built kernel to boot off a 405EP Eval
board?  I'd love to know what version... My kernel dies pretty early...

Regards,
