[PATCH v2 00/10] ARM: boards: add support for Enclustra Mercury SA2

[David Picard]

Add support for the Enclustra Mercury+ SA2, a Cyclone V based
SoC FPGA.
https://www.enclustra.com/en/products/system-on-chip-modules/mercury-sa2/

The SoM provides a 64MiB NOR QSPI flash, DDR3, Ethernet PHY, RTC.

The Cyclone V features a hardware ARM core (aka HPS) that can boot
from SD card (MMC), QSPI flash. This patch series focusses on MMC.
