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.
I have discovered that if I leave only icache enabled tftp works (more more quickly than without icache). So at the moment I enable by default dcache and icache, but, when I need to do tftp, I disable dcache.
Hoping it helps, Raffaele
