I may find another non-x86 board to test.
It is all there - I am using the existing support. If you see pci_run_vga_bios() it calls biosemu_run() in the emulation case. Re your other question I was looking for the VGA enable bit, as I remembered it from years ago. It doesn't seem to be needed for that platforms I have tested. But if it is generally needed we should add it. For the ROM, pci_rom_load() works for me, after pciauto_setup_rom() is called. I wonder if you haven't enabled the ROM BAR? I initially got the same result as you. Regards, Simon _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
