Tue Apr 9 13:41:46 UTC 2019
From: Eugen Hristev <eugen.hristev at microchip.com>
The SAMA5D2 ICP Board features the SAMA5D27 SoC,
together with QSPI Flash, Wilc3000 wireless device and
EtherCat support.
Signed-off-by: Eugen Hristev <eugen.hristev at microchip.com>

Changes in v2:
- created at91-sama5d2_icp-u-boot.dtsi with the pre-reloc properties
- removed some #ifdef as suggested by Stefan
- fixed issue with wrong SPL FAT FS in defconfig
- fixed build issue with wrong DRAM_BANKS redefine
