U-Boot: Patch Versatile Express to use config_distro_bootcmd.h
With this patch in place, ARMv7 NixOS can be booted in QEMU: qemu-system-arm -kernel u-boot -M vexpress-a9 -serial stdio -sd nixos-sd-image-armv7l-linux.img -m 1024 ...with all the features that boot.loader.generic-extlinux-compatible supports, like the boot generation menu and seamless kernel upgrades in the VM.

Subject: [PATCH] vexpress: Use config_distro_bootcmd
|
||||
|
||||
Also had to hack cli_readline.c, as one codepath in
|
||||
cli_readline_into_buffer doesn't respect the timeout.
