ARM: cns3xxx: Add CNS3420 Validation Board support
This patch adds support for CNS3420VB rev 1.3 boards. With this patch CNS3420VB boards are able to boot up to the userspace, with a console available on UART0. Signed-off-by: Anton Vorontsov <avorontsov@mvista.com>

This is a platform with an on-board ARM11 MPCore and has support
|
||||
for USB, USB-OTG, MMC/SD/SDIO, SATA, PCI-E, etc.
