why have you omitted this?
#define CONFIG_BOOTCOMMAND bootp;bootelf
#define CONFIG_CMD_ELF
Because I haven't tested `bootelf' command. I'm not should it work or not.
Another reason is that when I configure CONFIG_CMD_ELF I will get lots of
warning such as:

We can fix those files later. My point is that all qemu_mips variants should be configured with the same options. [...] why have you omitted the flash support? qemu-system-mips supports flash emulation with the option -pflash. It already works with a qemu_mips32 U-boot. Yes, I have tested with -pflash in qemu_mips64 either. I have forgot why I omit it now. By the way, which commit should I base on of my next patch? it is still git://git.denx.de/u-boot-mips.git master -- Best regards, Daniel ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
