4b724efdde Get rid of SINGLE_ONLY_FPU. Linux does not support half FPU other than 
by emulation of a full FPU.

e5adb8770e Hack to resolve longstanding prefetch issue 
Prefetching may be fatal on some systems if we're prefetching beyond the
end of memory on some systems.  It's also a seriously bad idea on non
dma-coherent systems.

Limit the number of cpu type options in the cpu menu to just those
types that are actually available for the select platform.

cb4262481f pci-expmem-hack 
CFE 1.2.5 and earlier fails to turn on the ExpMemEn bit in the
PCIFeatureControl register, which means that DMA does not work
beyond physical address 01_0000_0000, ergo to DRAM beyond 1GB.
    
With ExpMemEn turned on, 01_0000_0000-0f_ffff_ffff is mapped,
so DMA works for up to 61 GB of DRAM.
    
Will be fixed in CFE 1.2.6 (yet to be released).
