Currently, CONFIG_SPL_SPI_* #defines are used for controlling SPI boot in
SPL. These #defines do not allow the user to select SPI mode for the SPI flash
(there's no CONFIG_SPL_SPI_MODE, so the SPI mode is hardcoded in
spi_spl_load.c), and duplicate information already provided by
CONFIG_SF_DEFAULT_* #defines.Kill CONFIG_SPL_SPI_*, and use CONFIG_SF_DEFAULT_* instead.

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

Most of the SST flashes needs to write up using SST_WP, AAI

Flag status register polling is required for micron 512Mb flash
devices onwards, for performing erase/program operations.Like polling for WIP(Write-In-Progress) bit in read status register,
spi_flash_cmd_wait_ready will poll for PEC(Program-Erase-Control)
bit in flag status register.Signed-off-by: Jagannadha Sutradharudu Teki

a change in bank selection from user.bank read only valid for flashes which has > 16Mbytes those are

Enable device tree control of SPI flash, and use this to implement
memory-mapped SPI flash, which is supported on Intel chips.Signed-off-by: Simon Glass

At present it is difficult to extend the SPI flash structure since
all devices allocate it themselves, and few of them zero all fields.
Add a new function spi_flash_alloc() which can be used by SPI devices
to perform this allocation, and thus ensure that all devices can
better cope with SPI structure changes.Signed-off-by: Simon Glass

This patch adds a new member to struct spi_flash (u16 sector_size)
and updates the spi flash drivers to start populating it.This parameter can be used by spi flash commands that need to round
up units of operation to the flash's sector_size.Having this number in one place also allows duplicated code to be
further collapsed into one common location (such as erase parameter
and the detected message).Signed-off-by: Richard Retanubun
