[U-Boot] [PATCH 2/3 RESEND] devkit3250: add Timll DevKit3250 board initial support

Vladimir Zapolskiy
2011-11-07T21:58:17Z

This change adds a basic support for Embest/Timll DevKit3250 board,
NOR and UART are the only supported peripherals for a moment. The board
doesn't require low-level init, because the initial SDRAM and GPIO
configuration is performed during kickstart bootloader execution.
