004f15b600 sf: Add memory mapped read support
Qspi controller can have a memory mapped port which can be used for
data read. Added support to enable memory mapped port read.

This patch enables the following:
- It enables exchange of memory map address between mtd and qspi
through the introduction of "memory_map" flag.
- Add support to communicate to the driver that memory mapped
 transfer is to be started through introduction of new flags like
"SPI_XFER_MEM_MAP" and "SPI_XFER_MEM_MAP_END".

This will enable the spi controller to do memory mapped configurations
if required.

fdf8529afc powerpc : spi flash : Support to start from eSPI with SPL
This patch introduces SPL to enable a loader stub that being loaded by
the code from the internal on-chip ROM. It loads the final uboot image
into DDR, then jump to it to begin execution.

The SPL's size is sizeable, the maximum size must not exceed the size of L2
SRAM. It initializes the DDR through SPD code, and copys final uboot image
to DDR. So there are two stage uboot images:
	* spl_boot, 96KB size. The env variables are copied to L2 SRAM, so that
	ddr spd code can get the interleaving mode setting in env. It loads
	final uboot image from offset 96KB.
	* final uboot image, size is variable depends on the functions enabled.

e3ff9d51ec sf: Update sf to support all sizes of flashes
Updated the spi_flash framework to handle all sizes of flashes
using bank/extd addr reg facility

The current implementation in spi_flash supports 3-byte address mode
due to this up to 16Mbytes amount of flash is able to access for those
flashes which has an actual size of > 16MB.

As most of the flashes introduces a bank/extd address registers
for accessing the flashes in 16Mbytes of banks if the flash size
is > 16Mbytes, this new scheme will add the bank selection feature
for performing write/erase operations on all flashes.
