powerpc/83xx: new board support: MPC8360E-RDK
This is patch adds board file, device tree, and defconfig for the new board, made by Freescale Semiconductor Inc. and Logic Product Development. Currently supported: 1. UEC{1,2,7,4}; 2. I2C; 3. SPI; 4. NS16550 serial; 5. PCI and miniPCI; 6. Intel NOR StrataFlash X16 64Mbit PC28F640P30T85; 7. Graphics controller, Fujitsu MB86277. Not supported in this patch: 1. StMICRO NAND512W3A2BN6E, 512 Mbit (supported with FSL UPM NAND driver); 2. FHCI USB (supported with FHCI driver). 3. QE Serial UCCs (tested to not work with ucc_uart driver, reason unknown, yet); 4. ADC AD7843 (tested to work, but support via device tree depends on major SPI rework, GPIO API, etc); Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
