2013-10-07sf: Add memory mapped read supportPoddar, Sourav
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.

2013-08-20powerpc : spi flash : Support to start from eSPI with SPLYing Zhang
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.
