[U-Boot] [PATCH] make mxsldr behave like sb_loader.exe
Hi,
I have made a patch to mxsldr to be able to boot non-u-boot bootstreams (linux and barebox) as well as u-boot bootstreams.
I added an option to send one last BLTS command after uploading the firmware. This is tested with bootstreams that work with sb_loader.exe in windows as well.
Jacob Kjaergaard (1): add option to send a last interrupt transfer.
