+	  Enable caching for the memory reference code binary. This uses an
+	  MTRR (memory type range register) to turn on caching for the section
+	  of SPI flash that contains the memory reference code. This makes
+	  SDRAM init run faster.

+	  Sets the size of the cached area for the memory reference code.
+	  This ends at the end of SPI flash (address 0xffffffff) and is
+	  measured in KB. Typically this is set to 512, providing for 0.5MB
+	  of cached space.

+	help
+	  Sets the base of the data cache area in memory space. This is the
+	  start address of the cache-as-RAM (CAR) area and the address varies
+	  depending on the CPU. Once CAR is set up, read/write memory becomes
+	  available at this address and can be used temporarily until SDRAM
+	  is working.
+
+config DCACHE_RAM_SIZE
+	hex
+	depends on HAVE_MRC
+	default 0x40000
+	help
+	  Sets the total size of the data cache area in memory space. This
+	  sets the size of the cache-as-RAM (CAR) area. Note that much of the
+	  CAR space is required by the MRC. The CAR space available to U-Boot
+	  is normally at the start and typically extends to 1/4 or 1/2 of the
+	  available size.

+config DCACHE_RAM_MRC_VAR_SIZE
+	hex
+	depends on HAVE_MRC
+	help
+	  This is the amount of CAR (Cache as RAM) reserved for use by the
