quackboot (same idea as klompboot), from audit6
this is based directly on the audit6 final revision.
same idea as klompboot. remove u-boot and arm support,
remove pico-serprog, remove support for making release
archives, and basically see how small the build
system can possible get.
quackboot *beats* the very first klompboot, at 790 lines,
because klompboot 1 was just over 800 lines. klompboot 2
was 701 lines. vendor file logic is about 200 sloc so
the next klompboot will be about 600 lines.
this is the very first quackboot.

But -neither is enough to test if only the modified regions are copied to the -copy frame buffer, since we will want the two to be different in very -specific ways. - -Add a boolean argument to the existing helper function to indicate which -frame buffer we want to inspect, and update the existing callers. - -Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com> -Reviewed-by: Simon Glass <sjg@chromium.org> -Link: https://lore.kernel.org/u-boot/20230821135111.3558478-3-alpernebiyasak@gmail.com/ ---- - test/dm/video.c | 76 ++++++++++++++++++++++++++----------------------- - 1 file changed, 41 insertions(+), 35 deletions(-) - -diff --git a/test/dm/video.c b/test/dm/video.c -index 14e6af5181f1..50374cafc009 100644 ---- a/test/dm/video.c -+++ b/test/dm/video.c -@@ -56,22 +56,28 @@ DM_TEST(dm_test_video_base, UT_TESTF_SCAN_PDATA | UT_TESTF_SCAN_FDT);
