My tegra2 had such a thing.
It wasn't fun to use, but OTOH I repeatedly bricked my uboot.

PS: because the instructions said to build uboot on x86 with ARCH=arm,
but I was building it natively so omitted ARCH=arm... which broke it.
By the time I knew, I'd given up and was stuck with android bootloader...
