Mmm, i have :

    {   /* 7457 */
        0xffff0000, 0x80020000, "7457",
        CPU_FTR_SPLIT_ID_CACHE | CPU_FTR_USE_TB | CPU_FTR_CAN_NAP |
        CPU_FTR_L2CR | CPU_FTR_ALTIVEC_COMP | CPU_FTR_L3CR |
        CPU_FTR_HPTE_TABLE | CPU_FTR_SPEC7450 | CPU_FTR_NAP_DISABLE_L2_PR |
        CPU_FTR_HAS_HIGH_BATS,
        COMMON_PPC | PPC_FEATURE_HAS_ALTIVEC,
        32, 32,
        __setup_cpu_745x
    },

Which should be ok, since there seem to be no way to distinguish a 7447
from a 7457 anyway (apart from maybe L2 cache probing or such).

And indeed, the problem seems to be that i get /cpus, and not
/cpus/PowerPC,74x7. I thought that the /cpus should give the cpu per
default or something such. What should i do here, i can go look for a
PowerPC,74x7, but the board can also come with other CPUs (the 750Cxe
for now). Maybe i could remove the cpus checking code completely, and go
looking for the cpu type directly.

Friendly,

Sven Luther
