Perhaps the problem is elsewhere as U-Boot master also broke
vexpress_ca15_tc2 and mx6cuboxi targets:

$ qemu-system-arm -m 1024 -nographic -M vexpress-a15 -dtb /usr/local/share/dtb/arm/vexpress-v2p-ca15-tc1.dtb -kernel /usr/local/share/u-boot/vexpress_ca15_tc2/u-boot -sd /tmp/miniroot-am335x-62.fs
WARNING: Image format was not specified for '/tmp/miniroot-am335x-62.fs' and probing guessed raw.
	 Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
	 Specify the 'raw' format explicitly to remove the restrictions.
