This patch introduces the support for Keymile's kmp204x reference design. This design is based on Freescale's P2040/P2041 SoC. The peripherals used by this design are: - DDR3 RAM with SPD support - SPI NOR Flash as boot medium - NAND Flash - 2 PCIe busses (hosts 1 and 3) - 3 FMAN Ethernet devices (FMAN1 DTSEC1/2/5) - 3 Local Bus windows, with one dedicated to the QRIO reset/power mgmt FPGA - 2 HW I2C busses - last but not least, the mandatory serial port The board/keymile/kmp204x code is mostly based on Freescale's P2041rdb support and was changed according to our design (that means essentially removing what is not present on the designs and a few adaptations). There is currently only one prototype board that is based on this design and this patch also introduces it. The board is called kmlion1.
