ba264b3403 Au1[12]00 mmc driver. Only tested on the Au1200 at this point though 
it should work on the Au1100 as well. Updated defconfig to include driver.

e97288386a The type of sum in csum_tcpudp_nofold is "unsigned int", so when we assign 
to it in an asm() block, and we're running on a system with 64-bit
registers, it is vitally important that we sign extend it correctly before
returning to C.  Otherwise the stray high bits will be preserved into
csum_fold, and on the SB-1 processor, 32-bit arithmetic on a non
sign-extended register will yield surprising results.
    
This caused incorrect checksums in some UDP packets for NFS root.  The
problem was mild when using a 10.0.1.x IP address, but severe when
using 192.168.1.x.

533330bf7f On CONFIG_64BIT_PHYS_ADDR, pfn always fits in 'unsigned long', but 
pfn<<PAGE_SHIFT sometimes extends beyond.  The pte is big enough to hold
'long long', but the shift in pfn_pte() needs to do its calculation with
enough bits to hold the result.
