Sometimes it is useful to build an image even though external binaries are not present. This allows the build system to continue to function without these files, albeit not producing valid images. U-Boot does with with ATF (ARM Trusted Firmware) today. Add a new flag to binman to request this behaviour. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
