* Freescale Enhanced Secure Digital Host Controller (eSDHC)
The Enhanced Secure Digital Host Controller provides an interface
for MMC, SD, and SDIO types of memory cards.
Required properties:
- compatible : should be
"fsl,<chip>-esdhc", "fsl,mpc8379-esdhc" for MPC83xx processors.
"fsl,<chip>-esdhc", "fsl,mpc8536-esdhc" for MPC85xx processors.
- reg : should contain eSDHC registers location and length.
- interrupts : should contain eSDHC interrupt.
- interrupt-parent : interrupt source phandle.
- clock-frequency : specifies eSDHC base clock frequency.
Example:
sdhci@2e000 {
compatible = "fsl,mpc8378-esdhc", "fsl,mpc8379-esdhc";
reg = <0x2e000 0x1000>;
interrupts = <42 0x8>;
interrupt-parent = <&ipic>;
/* Filled in by U-Boot */
clock-frequency = <0>;
};

help
This option allows you to set the maximum number of CAM slots that
will be used to map low memory. There are a limited number of slots
available and even more limited number that will fit in the L1 MMU.
However, using more entries will allow mapping more low memory. This
can be useful in optimizing the layout of kernel virtual memory.
Say N here unless you know what you are doing.
