Hi, this broke a couple of machines, quoting Tom. I'm dropping it for now.
NAK. This introduces various breakage:
12: Merge branch 'master' of git://git.denx.de/u-boot-usb
arm: + VCMA9 beagle_x15 at91rm9200ek_ram peach-pi snow smdk5250
am43xx_evm dr
a7xx_evm_uart3 k2l_evm am43xx_evm_qspiboot smdk5420 dra7xx_evm smdk2410
at91rm9200ek dr
a7xx_evm_qspiboot k2hk_evm k2e_evm peach-pit
powerpc: + PIP405 MIP405
The powerpc board breakage is the same as some of the ARM ones so fix it
once and they'll come along.
Best regards,
Marek Vasut
