config DM_SPI
bool "Enable Driver Model for SPI drivers"
depends on DM
help
Enable driver model for SPI. The SPI slave interface
(spi_setup_slave(), spi_xfer(), etc.) is then implemented by
the SPI uclass. Drivers provide methods to access the SPI
buses that they control. The uclass interface is defined in
include/spi.h. The existing spi_slave structure is attached
as 'parent data' to every slave on each bus. Slaves
typically use driver-private data instead of extending the
spi_slave structure.

config CADENCE_QSPI
bool "Cadence QSPI driver"
help
Enable the Cadence Quad-SPI (QSPI) driver. This driver can be
used to access the SPI NOR flash on platforms embedding this
Cadence IP core.
config DESIGNWARE_SPI
bool "Designware SPI driver"
help
Enable the Designware SPI driver. This driver can be used to
access the SPI NOR flash on platforms embedding this Designware
IP core.
config EXYNOS_SPI
bool "Samsung Exynos SPI driver"
help
Enable the Samsung Exynos SPI driver. This driver can be used to
access the SPI NOR flash on platforms embedding this Samsung
Exynos IP core.
config FSL_DSPI
bool "Freescale DSPI driver"
help
Enable the Freescale DSPI driver. This driver can be used to
access the SPI NOR flash and SPI Data flash on platforms embedding
this Freescale DSPI IP core. LS102xA and Colibri VF50/VF61 platforms
use this driver.
config FSL_QSPI
bool "Freescale QSPI driver"
help
Enable the Freescale Quad-SPI (QSPI) driver. This driver can be
used to access the SPI NOR flash on platforms embedding this
Freescale IP core.
config ICH_SPI
bool "Intel ICH SPI driver"
help
Enable the Intel ICH SPI driver. This driver can be used to
access the SPI NOR flash on platforms embedding this Intel
ICH IP core.
config ROCKCHIP_SPI
bool "Rockchip SPI driver"
help
Enable the Rockchip SPI driver, used to access SPI NOR flash and
other SPI peripherals (such as the Chrome OS EC) on Rockchip SoCs.
This uses driver model and requires a device tree binding to
operate.
config SANDBOX_SPI
bool "Sandbox SPI driver"
depends on SANDBOX && DM
help
Enable SPI support for sandbox. This is an emulation of a real SPI
bus. Devices can be attached to the bus using the device tree
which specifies the driver to use. As an example, see this device
tree fragment from sandbox.dts. It shows that the SPI bus has a
single flash device on chip select 0 which is emulated by the driver
for "sandbox,spi-flash", which is in drivers/mtd/spi/sandbox.c.

bool "nVidia Tegra114 SPI driver"
help
Enable the nVidia Tegra114 SPI driver. This driver can be used to
access the SPI NOR flash on platforms embedding this nVidia Tegra114
IP core.
This controller is different than the older SoCs SPI controller and
also register interface get changed with this controller.
config TEGRA20_SFLASH
bool "nVidia Tegra20 Serial Flash controller driver"
help
Enable the nVidia Tegra20 Serial Flash controller driver. This driver
can be used to access the SPI NOR flash on platforms embedding this
nVidia Tegra20 IP core.
config TEGRA20_SLINK
bool "nVidia Tegra20/Tegra30 SLINK driver"
help
Enable the nVidia Tegra20/Tegra30 SLINK driver. This driver can
be used to access the SPI NOR flash on platforms embedding this
nVidia Tegra20/Tegra30 IP cores.
config XILINX_SPI
bool "Xilinx SPI driver"
help
Enable the Xilinx SPI driver from the Xilinx EDK. This SPI
controller support 8 bit SPI transfers only, with or w/o FIFO.
For more info on Xilinx SPI Register Definitions and Overview
see driver file - drivers/spi/xilinx_spi.c
config ZYNQ_SPI
bool "Zynq SPI driver"
depends on ARCH_ZYNQ || TARGET_XILINX_ZYNQMP
help
Enable the Zynq SPI driver. This driver can be used to
access the SPI NOR flash on platforms embedding this Zynq
SPI IP core.
endif # if DM_SPI
config FSL_ESPI
bool "Freescale eSPI driver"
help
Enable the Freescale eSPI driver. This driver can be used to
access the SPI interface and SPI NOR flash on platforms embedding
this Freescale eSPI IP core.
config TI_QSPI
bool "TI QSPI driver"
help
Enable the TI Quad-SPI (QSPI) driver for DRA7xx and AM43xx evms.
This driver support spi flash single, quad and memory reads.
