Hello Ti
We use am335x Starter Kit SDK6 on our custom board and don't found any command in u-boot level after I have build the u-boot.
===========================================
Hit any key to stop autoboot: 0
Unknown command 'mmc' - try 'help'
Unknown command 'mmc' - try 'help'
Unknown command 'run' - try 'help'
U-Boot# help
Unknown command 'help' - try 'help'
U-Boot#
=============================================
These steps we were taking:
1. cd <SDK_folder>/ti-sdk-am335x-evm-06.00.00.00/board-support/u-boot-2013.01.01-psp06.00.00.00$
2. export ARCH=arm
3. export CROSS_COMPILE=~/ti-sdk-am335x-evm-06.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin/arm-linux-gnueabihf-
4. export PATH="<SDK INSTALL DIR>/linux-devkit/sysroots/i686-arago-linux/usr/bin:$PATH
5. make am335x_evm_config
6 make

I don't think that my code is wrong , because I just revise the part of read eeprom. Thank you.
and I attache the patch with u-boot
