arm: mvebu: Add basic support for Armada 375 eval board db-88f6720
This patch adds basic support for the Marvell A375 eval board. Tested are the following interfaces: - I2C - SPI - SPI NOR - Ethernet (mvpp2), port 0 & 1 Currently the A375 SerDes and DDR3 init code is not intergrated. So the SPL U-Boot is not fully functional. Right now, this A375 mainline U-Boot can only be used by chainloading it via the original Marvell U-Boot. This can be done via this command: => tftpboot 00800000 a375/u-boot-dtb.bin;go 00800000 Signed-off-by: Stefan Roese <sr@denx.de> Cc: Luka Perkov <luka.perkov@sartura.hr>
