Thu May 21 22:24:29 CEST 2009


Kirkwood family controllers are highly integrated SOCs
based on Feroceon-88FR131/Sheeva-88SV131 cpu core.

SOC versions supported:-
1) 88F6281-A0       define CONFIG_KW88F6281_A0
2) 88F6192-A0       define CONFIG_KW88F6192_A0

Other supported features:-
1) get_random_hex() fucntion
2) SPI port controller driver
3) PCI Express port initialization
