Subject: test/py: Add a way to start sandbox without a device tree
X-Git-Tag: v2022.07~64^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ee93f6129d0851b8667efaa5dc91ee201cce24b8;p=platform%2Fkernel%2Fu-boot.git

test/py: Add a way to start sandbox without a device tree

This is useful sometimes when running a specific test. Add support for it
in the existing restart_uboot_with_flags() function.
