Does this mean you cannot run 1G of lowmem on a 85xx? On 82xx I run 1G of lowmem, and when we finaly upgrade our product to a 85xx something, Iw was planning on doing the same. (For those interested: To run 1G lowmwm on 82xx (at least under arch/ppc) CONFIG_ADVANCED_OPTIONS=y CONFIG_HIGHMEM_START=0xfe000000 CONFIG_LOWMEM_SIZE_BOOL=y CONFIG_LOWMEM_SIZE=0x40000000 CONFIG_KERNEL_START_BOOL=y CONFIG_KERNEL_START=0xa0000000 _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
