    ARM (ARM926ejs): add data cache support, tested on magnesium and tx25 board


My 'Basi' board, based on DaVinci dm365, can read the uImage (1.5MB)
in 0.7 sec (with ext2load) instead of 2 sec.
If I read using mmc read I can reach 0.3 sec, but I need to know the dimension.

Take in account only that tftpboot doesn't work with dcache/icache enabled.

Regards,
Raffaele
