General question: should we rename "amcc" into "apm" ?

What about the configuration with 128 MiB NOR flash? Would it not be
more flexible to use something like

	program_tlb(CONFIG_SYS_FLASH_END_PHYS-flash_info[0].size,
		-flash_info[0].size,
		flash_info[0].size, TLB_WORD2_I_ENABLE);

with
	CONFIG_SYS_FLASH_END_PHYS_H = 0x4
and	CONFIG_SYS_FLASH_END_PHYS_L = 0xD0000000

?


BTW: Please use "flash" (globally) instead of FLASH - "flash" is not
an abbreviation.

"on this board" or "on these boards"
