ARM: at91: add basic sama5d2-som1-ek1 support
The ATSAMA5D27-SOM1-EK1 is Microchip's evaluation kit for the SAMA5D2
System in Packages (SiPs). The ATSAMA5D27C-D1G-CU SIP embeds 128 MB
of DDR2 DRAM and the SoM has a PMIC, QSPI flash and a 100Mbps PHY.
barebox already supports the sama5d2 clocks, GPIO/Pinctrl, QSPI
controller and Ethernet MAC. Most notable omission is the sama5d2
variant of the SDHCI, which differs from the MCI used by previous AT91
boards, but we kernel boot over the network works, so lets add the board
now and have the SDHCI follow later.
