-+* OCTEON SD/MMC Host Controller
-+
-+This controller is present on some members of the Cavium OCTEON SoC
-+family, provide an interface for eMMC, MMC and SD devices.  There is a
-+single controller that may have several "slots" connected.  These
-+slots appear as children of the main controller node.
-+The DMA engine is an integral part of the controller block.
-+
-+Required properties:
-+- compatible : Should be "cavium,octeon-6130-mmc" or "cavium,octeon-7890-mmc"
-+- reg : Two entries:
-+	1) The base address of the MMC controller register bank.
-+	2) The base address of the MMC DMA engine register bank.
-+- interrupts :
-+	For "cavium,octeon-6130-mmc": two entries:
-+	1) The MMC controller interrupt line.
-+	2) The MMC DMA engine interrupt line.
-+	For "cavium,octeon-7890-mmc": nine entries:
-+	1) The next block transfer of a multiblock transfer has completed (BUF_DONE)
-+	2) Operation completed successfully (CMD_DONE).
-+	3) DMA transfer completed successfully (DMA_DONE).
-+	4) Operation encountered an error (CMD_ERR).
-+	5) DMA transfer encountered an error (DMA_ERR).
-+	6) Switch operation completed successfully (SWITCH_DONE).
-+	7) Switch operation encountered an error (SWITCH_ERR).
-+	8) Internal DMA engine request completion interrupt (DONE).
-+	9) Internal DMA FIFO underflow (FIFO).
-+- #address-cells : Must be <1>
-+- #size-cells : Must be <0>
-+
-+Required properties of child nodes:
-+- compatible : Should be "cavium,octeon-6130-mmc-slot".
-+- reg : The slot number.
-+
-+Optional properties of child nodes:
-+- cd-gpios : Specify GPIOs for card detection
-+- wp-gpios : Specify GPIOs for write protection
-+- power-gpios : Specify GPIOs for power control
-+- cavium,bus-max-width : The number of data lines present in the slot.
-+	Default is 8.
-+- spi-max-frequency : The maximum operating frequency of the slot.
-+	Default is 52000000.
-+- cavium,cmd-clk-skew : the amount of delay (in pS) past the clock edge
-+	to sample the command pin.
-+- cavium,dat-clk-skew : the amount of delay (in pS) past the clock edge
-+	to sample the data pin.
-+
-+Example:
-+	mmc@1180000002000 {
-+		compatible = "cavium,octeon-6130-mmc";
-+		reg = <0x11800 0x00002000 0x0 0x100>,
-+		      <0x11800 0x00000168 0x0 0x20>;
-+		#address-cells = <1>;
-+		#size-cells = <0>;
-+		/* EMM irq, DMA irq */
-+		interrupts = <1 19>, <0 63>;
-+
-+		/* The board only has a single MMC slot */
-+		mmc-slot@0 {
-+			compatible = "cavium,octeon-6130-mmc-slot";
-+			reg = <0>;
-+			spi-max-frequency = <20000000>;
-+			/* bus width can be 1, 4 or 8 */
-+			cavium,bus-max-width = <8>;
-+			cd-gpios = <&gpio 9 0>;
-+			wp-gpios = <&gpio 10 0>;
-+			power-gpios = <&gpio 8 0>;

-From: =?utf-8?q?Micha=C5=82_Osowiecki?= <michal.osowiecki@gmail.com>

-Cisco RV0XX u-boot sets MEM=2048 as boot param. We assume that at least 
-4MB (mem_alloc_size) of ram is needed to run linux on cavium boards, so 
-if mem < 4M - ignore it and set default value
