-/* U-Boot - Startup Code for AMCC 4xx PowerPC based Embedded Boards
- The processor starts at 0xfffffffc and the code is executed
- from flash/rom.
- in memory, but as long we don't jump around before relocating.
- board_init lies at a quite high address and when the cpu has
- jumped there, everything is ok.
- This works because the cpu gives the FLASH (CS0) the whole
- address space at startup, and board_init lies as a echo of
- the flash somewhere up there in the memorymap.
- board_init will change CS0 to be positioned at the correct
- address and (s)dram will be positioned at address 0

- Startup code for IBM/AMCC PowerPC 4xx (PPC4xx) based boards
It appears that the old comment contained some information about how booting and especially address resolution works on 4xx. Is there some way to keep this (non-obvious, at least to me) information, instead of just deleting it?
Best regards,
Wolfgang Denk
