Hi, I'm new to uboot mips port and first decided to try it with qemu. I've encountered some problems with UART, but I guess that's more qemu issue(lsr reg is not updated when the line is available).
Another issue I faced was code execution after the relocation is done. The address of board_init_r is not computed correctly(it was relative to boot ROM address space/bfc00000). Is it specific to qemu(I don't see the reference here though) or is it a generic mips port issue? Attached patch allows me to proceed with the boot in qemu.
And last - why do we need relocation at all with u-boot? Performance constraints?
Thanks, -- dmytro
