I have an MMC device which has at least boot HW partitions, yet with the 
very latest code in u-boot.git, I don't see the additional lines 
mentioned above. My HW partitions are still working fine, since I can 
select a boot partition and mmcinfo shows the correct "Capacity" for it:

Any ideas why?

Tegra124 (Jetson TK1) # mmc dev 0
switch to partitions #0, OK
mmc0(part 0) is current device

Tegra124 (Jetson TK1) # mmc dev 0 1 <<<< select "boot0" HW partition
