3config DM_SPI
4	bool "Enable Driver Model for SPI drivers"
5	depends on DM
6	help
7	  Enable driver model for SPI. The SPI slave interface
8	  (spi_setup_slave(), spi_xfer(), etc.) is then implemented by
9	  the SPI uclass. Drivers provide methods to access the SPI
10	  buses that they control. The uclass interface is defined in
11	  include/spi.h. The existing spi_slave structure is attached
12	  as 'parent data' to every slave on each bus. Slaves
13	  typically use driver-private data instead of extending the
14	  spi_slave structure.

19	bool "Cadence QSPI driver"
20	help
21	  Enable the Cadence Quad-SPI (QSPI) driver. This driver can be
22	  used to access the SPI NOR flash on platforms embedding this
23	  Cadence IP core.
24
25config DESIGNWARE_SPI
26	bool "Designware SPI driver"
27	help
28	  Enable the Designware SPI driver. This driver can be used to
29	  access the SPI NOR flash on platforms embedding this Designware
30	  IP core.
31
32config EXYNOS_SPI
33	bool "Samsung Exynos SPI driver"
34	help
35	  Enable the Samsung Exynos SPI driver. This driver can be used to
36	  access the SPI NOR flash on platforms embedding this Samsung
37	  Exynos IP core.
38
39config FSL_DSPI
40	bool "Freescale DSPI driver"
41	help
42	  Enable the Freescale DSPI driver. This driver can be used to
43	  access the SPI NOR flash and SPI Data flash on platforms embedding
44	  this Freescale DSPI IP core. LS102xA and Colibri VF50/VF61 platforms
45	  use this driver.
46
47config FSL_QSPI
48	bool "Freescale QSPI driver"
49	help
50	  Enable the Freescale Quad-SPI (QSPI) driver. This driver can be
51	  used to access the SPI NOR flash on platforms embedding this
52	  Freescale IP core.
53
54config ICH_SPI
55	bool "Intel ICH SPI driver"
56	help
57	  Enable the Intel ICH SPI driver. This driver can be used to
58	  access the SPI NOR flash on platforms embedding this Intel
59	  ICH IP core.

61config ROCKCHIP_SPI
62	bool "Rockchip SPI driver"
63	help
64	  Enable the Rockchip SPI driver, used to access SPI NOR flash and
65	  other SPI peripherals (such as the Chrome OS EC) on Rockchip SoCs.
66	  This uses driver model and requires a device tree binding to
67	  operate.
68
69config SANDBOX_SPI
70	bool "Sandbox SPI driver"
71	depends on SANDBOX && DM
72	help
73	  Enable SPI support for sandbox. This is an emulation of a real SPI
74	  bus. Devices can be attached to the bus using the device tree
75	  which specifies the driver to use. As an example, see this device
76	  tree fragment from sandbox.dts. It shows that the SPI bus has a
77	  single flash device on chip select 0 which is emulated by the driver
78	  for "sandbox,spi-flash", which is in drivers/mtd/spi/sandbox.c.

105	bool "nVidia Tegra20 Serial Flash controller driver"
106	help
107	  Enable the nVidia Tegra20 Serial Flash controller driver. This driver
108	  can be used to access the SPI NOR flash on platforms embedding this
109	  nVidia Tegra20 IP core.

111config TEGRA20_SLINK
112	bool "nVidia Tegra20/Tegra30 SLINK driver"
113	help
114	  Enable the nVidia Tegra20/Tegra30 SLINK driver. This driver can
115	  be used to access the SPI NOR flash on platforms embedding this
116	  nVidia Tegra20/Tegra30 IP cores.
