[PATCH 0/8] arm: mvebu: Add Armada 38x pin muxing support

[Tony Dinh]

Hi Pali,

After correcting my MPP configuration in board_early_init, I ran the
test again with this patch series. Everything works (upon u-boot
startup) : Ethernet, SPI, SATA and USB.

Board: Synology DS116, Armada 385 (out-of-tree u-boot)
Tested-by: Tony Dinh <mibodhi at gmail.com>

Thanks,
Tony
