| | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a SPI flash driver which simulates SPI flash clients. Currently supports the bare min that U-Boot requires: you can probe, read, erase, and write. Should be easy to extend to make it behave more exactly like a real SPI flash, but this is good enough to merge now. sjg@chromium.org added a README and tidied up code a little. Added a required map_sysmem() for sandbox. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Simon Glass <sjg@chromium.org>

* | powerpc: spiflash:Add corenet devices support in eSPI SPLPriyanka Jain2013-12-04-0/+5
|/ | | | | | | | | | | | | | | Existing eSPI SPL framework assumes booting from spi-image with boot_format header which contains final u-boot Image offset and size. No such header is present in case of corenet devices like T1040 as corenet deivces use PBI-RCW based intialization. So, for corenet deives, SPL bootloader use values provided at compilation time. These values can be defined in board specific config file. Signed-off-by: Priyanka Jain <Priyanka.Jain@freescale.com> Acked-by: York Sun <yorksun@freescale.com>

| | | | | | | | | | | | | | | | | | 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.
