Dear Sebastien Carlier,

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...

Best regards,

Wolfgang Denk
