u-boot v2016.07

Hi,

It seems there were some OMAP5 related fixes since v2015.10, so I've rebased hns' letux-extensions u-boot branch hoping it would help to boot my board. Unfortunately it did not help (my board still always hangs/crashes randomly in u-boot or the kernel, if it manages to reach it), but maybe somebody will find it useful:

git://git.openpandora.org/pandora-u-boot.git letux-extensions-v2016.07

While this u-boot works the same as hns' build for me (sometimes boots), MLO (aka SPL) won't even show any signs of life. Haven't tried to investigate why.
