very interesting B-). Applied to u-boot-mips/testing branch.
I'd like to give it a try, but I have to admit that I've never tested qemu for U-Boot/Mips; I've tested only with Linux/Mips kernel. Could you give me some HOWTOs, steps to reproduce, expected output results, etc. Or any usuful pointers...
make qemu_mips_config ; make
Copy (or symlink) u-boot.bin to mips_bios.bin and launch qemu-system-mips -L . /dev/null -L . so that qemu picks the BIOS from the current directory and /dev/null because qemu wants a disk image. Qemu willl load and launch U-Boot.
Add -hda file.img to Qemu cmd line in order to emulate a hard-disk and do ide reset at the U-Boot prompt ; the disk (or disks) should be identified. Check U-Boot doc for booting fromHD :-)
Add -tftp / and then do dhcp (or directly tftp) and then bootelf (on vmlinux) or bootm (on uimage).
Main purpose is to be able to develop U-Boot modules with no hardware. Secondary is for me to learn how it works :-) in order to develop a free BIOS for the MTI Malta board, as emulated by Qemu (comes with PCI and stuff). Or even for the real board. I have that sort-of-working too, but I'm not very happy with the PCI bus driver .
