Looks nice - two hints/annotations:

1.) You should avoid the serial_init() & main_loop() calls inside your 
board_init() function. I think it's an unclean U-Boot coding style. The right 
place would be in lib_microblaze/board.c functions board_init_[rf]() or 
board_init() for targets without Flash/RAM abstraction (like Nios).
Why do you do so?

2.) As far as I can remember the Microblaze CPU is the Soft CPU by Xilinx 
like Nios by Altera. So the core will be very very flexible and have to be 
configurable. Have a look at the differen Nios targets and let you inspire to 
map your specific CPU configuration into the U-Boot configuration managment.

Best regards,
