Hi Greg,
1. The linker script changes don't conform to the modern way of setting
the base and size of kernel RAM
2. Why the special case for vectors 240->255?
(I am unlikely to merge any special cases in that code)
1. I'm not sure what you mean by this. config.linux-2.6.x looks the
same as M5235EVB regarding CONFIG_RAMBASE and SIZE. Are you talking
about config.c?
No, this change:

Given you have the CONFIG_KERNELBASE, etc, set correctly (and it
does look like they are) there is no need to special case in here.
2. I dont blame you for not wanting that code. That grew out of the
fact that i changed to boot image.bin at 0x400, but then changed to
needing the u-boot mkimage header before the image start. there were
already boot roms out there so i couldnt move the start up to something
logical. I want to get away from the that hack ASAP so i'll resubmit
the BSP without that after i understand what is needed to fix issue #1.
OK, sounds good.
Regards
Greg
