X-Git-Url: http://git.dujemihanovic.xyz/%22http:/www.sics.se/static/git-logo.png?a=commitdiff_plain;h=d4f22cb39e92ebfce74003b5779d6d6addc797e2;p=u-boot.git

test: dm: Add test for fastboot mmc partition naming

This test verifies the mapping between fastboot partitions and partitions
as understood by U-Boot. It also tests the creation of GPT partitions,
though that is not the primary goal.
