Hello all,
Here is a patch against the current CVS for microblaze port of u-boot. I does nothing but boot itself, but this can be a start.
Suggestions, thoughts, and comments are welcome, of course.
best regards,

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, Stepha Linz
