[U-Boot-Users] [PATCH] mpc85xx: Update linker scripts for Freescale boards

2008-07-30 Thread Kumar Gala 
* Move to using absolute addressing always.  Makes the scripts a bit more
  portable and common
* Moved .bss after the end of the image.  These allows us to have more
  room in the resulting binary image for code and data.
* Removed .text object files that aren't really needed
* Added drivers/bios_emulator/atibios.o so the files are common since we
  do run ATI video cards on some boards

When you exclude all the other objects here, then why do you have to
include atibios.o ?

I haven't figured that out yet.  I know my boot fails if I dont.

Guess I should go figure that out... I was hoping to blissfully ignore  
this ;)

Ok, the issue is that the atibios/x86 emu was causing _end not to be 4- 
byte aligned and by putting in earlier it would get aligned for us.   
I've posted a new patch that adds a proper ALIGN for _end and dropped  
the explicit listing of atibios.o and start.o since they aren't needed.
