Actually I think that using "CFG_FLASH_BASE=0xFF800000" or similar
for a high-boot configuration is not optimal, as it does not adjust
automatically for varying flash sizes.
Usually I use something like
#define CFG_FLASH_BASE (0-flash_info.size)
#define CFG_FLASH_BASE (0-flash_info.size-flash_info.size)
in such cases.
Just an idea....

No, I'm not going to explain it. If you can't figure it out, you
didn't want to know anyway... :-)
