[PATCH v2 3/3] TI814X: Create board support and enable build for TI8148 EVM

2011-09-21 Thread Hemant Pedanekar 
This patch adds minimal support and build configuration for TI8148 EVM. Also
adds support for low level debugging on UART1 console on the EVM.

Hmm I guess we still have board specific map_io in board-ti8668evm.c
also. Those would be better replaced with ti81xx_map_io in
mach-omap2/common.c. Care to take a look at that?

Please add this all to board-ti8168evm.c instead of adding a new
board-*.c file. With the upcoming device tree conversion most of
these will disappear anyways.

Regards,

Tony

Yes, you are right. I will do that.

Ok, I will do that.
