This patch introduces support for building U-Boot to run on the MIPS Boston development board. This is a board built around an FPGA & an Intel EG20T Platform Controller Hub, used largely as part of the development of new CPUs and their software support. It is essentially the successor to the older MIPS Malta board. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
