This patch provides support to set the quad enable bit on flash.
quad enable bit needs to set before performing any quad IO
operations on respective SPI flashes.Currently added set quad enable bit for winbond and spansion flash
devices. stmicro flash doesn't require to set as qeb is volatile.
remaining flash devices support will add in future patches.Signed-off-by: Jagannadha Sutradharudu Teki

This patch add quad commands support like
- QUAD_PAGE_PROGRAM => for write program
- QUAD_OUTPUT_FAST ->> for read programSigned-off-by: Jagannadha Sutradharudu Teki

Current sf uses FAST_READ command, this patch adds support to
use the different/extended read command.This implementation will determine the fastest command by taking
the supported commands from the flash and the controller, controller
is always been a priority.Signed-off-by: Jagannadha Sutradharudu Teki

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
