Is it not possible to tell the linker to place a made-up 32 kB symbol within the text section at address 0x40008000? I am not familiar enough with ld to tell whether there are restrictions for setting the absolute address of a symbol that would disallow it in this case.
I don't know such a method. We would not even have to make up any symbols - if we could forst the Linker to place "environment" at 0x40008000 and "redundand_environment" at 0x4000c000 everything would be perfect. Before this patch, this was what we had:
... 0x40005ebc inflateInit2_ 0x400058f4 inflate_table arch/powerpc/lib/cache.o(.text) .text 0x40007c20 0x64 arch/powerpc/lib/cache.o 0x40007c20 flush_cache 0x00008000 . = DEFINED (env_offset)?env_offset:. *fill* 0x40007c84 0x37c 00 common/env_embedded.o(.ppcenv) .ppcenv 0x40008000 0x8000 common/env_embedded.o 0x40008000 environment 0x4000c000 redundand_environment *(.text) .text 0x40010000 0x4 common/env_embedded.o 0x40010000 env_size .text 0x40010004 0x0 lib/libgeneric.a(ctype.o) .text 0x40010004 0x10c lib/libgeneric.a(div64.o) 0x40010004 __div64_32 ...
But I don't know of a way to enforce this...
