[U-Boot] [PATCH 0/3] add support for am43xx-sk
Hi,
First patch prints out the board name because I really didn't want to keep going back to design documents to find out what's written on the EEPROM.
Second patch adds support for am43xx-sk.
Thir patch fixes mmcboot so that it actually tries to load images from mmc.
cheers

when porting u-boot to a new am43xx board, it helps to know the name of the current unsupported board so we don't have to hunt for design documents to figure out what's written in the EEPROM.

AM43xx Starter Kit is a new board based on AM437x line of SoCs. Being a low-cost EVM and small size EVM are intended to provide an entry level development platform on a full fledged Hardware System.

if we don't set devtype properly 'load' will fail.
