2025-12-01spi: cadence: Add driver for xSPIBoon Khai Ng
This patch ports the Cadence xSPI controller driver from the Linux kernel. The controller supports three operating modes: 1. ACMD (Auto Command) mode - Includes PIO and CDMA submodes. - CDMA mode uses linked descriptors for high-performance, low-overhead operation. - PIO mode is suitable for simple, single-command transactions. 2. STIG (Software Triggered Instruction Generator) mode - Issues low-level 128-bit instructions to memory. - Uses the Slave DMA interface for data transfers. 3. Direct mode - Enables direct data access through the slave interface without commands. Currently, only the STIG work mode is enabled. Additional modes will be supported in future updates. At the same time, also enabling the kconfig option for xSPI driver. This driver has been ported and functionally verified on the Intel Simics platform. It is intended for evaluation and experimental use at this stage.

2022-09-13spi: aspeed: Add ASPEED SPI controller driverChin-Ting Kuo
Add ASPEED BMC FMC/SPI memory controller driver with spi-mem interface for AST2500 and AST2600 platform. There are three SPI memory controllers embedded in an ASPEED SoC. - FMC: Named as Firmware Memory Controller. After AC on, MCU ROM fetches initial device boot image from FMC chip select(CS) 0. - SPI1: Play the role of a SPI Master controller. Or, there is a dedicated path for HOST(X86) to access its BIOS flash mounted under BMC. spi-aspeed-smc.c implements the control sequence when SPI1 is a SPI master. - SPI2: It is a pure SPI flash controller. For most scenarios, flashes mounted under it are for pure storage purpose. ASPEED SPI controller supports 1-1-1, 1-1-2 and 1-1-4 SPI flash mode. Three types of command mode are supported, normal mode, command read/write mode and user mode. - Normal mode: Default mode. After power on, normal read command 03h or 13h is used to fetch boot image from SPI flash. - AST2500: Only 03h command can be used after power on or reset. - AST2600: If FMC04[6:4] is set, 13h command is used, otherwise, 03h command. The address length is decided by FMC04[2:0]. - Command mode: SPI controller can send command and address automatically when CPU read/write the related remapped or decoded address area. The command used by this mode can be configured by FMC10/14/18[23:16]. Also, the address length is decided by FMC04[2:0]. This mode will be implemented in the following patch series. - User mode: It is a traditional and pure SPI operation, where SPI transmission is controlled by CPU. It is the main mode in this patch. Each SPI controller in ASPEED SoC has its own decoded address mapping. Within each SPI controller decoded address, driver can assign a specific address region for each CS of a SPI controller. The decoded address cannot overlap to each other. With normal mode and command mode, the decoded address accessed by the CPU determines which CS is active. When user mode is adopted, the CS decoded address is a FIFO, CPU can send/receive any SPI transmission by accessing the related decoded address for the target CS. This patch only implements user mode initially. Command read/write mode will be implemented in the following patches. Signed-off-by: Chin-Ting Kuo <chin-ting_kuo@aspeedtech.com>

This patch adds support for the Rockchip serial flash controller found on the PX30 SoC. It should work for versions 3-5 of the SFC IP, however I am only able to test it on v3. This is adapted from the WIP SPI-MEM driver for the SFC on mainline Linux. Note that the main difference between this and earlier versions of the driver is that this one does not support DMA. In testing the performance difference (performing a dual mode read on a 128Mb chip) is negligible. DMA, if used, must also be disabled in SPL mode when using A-TF anyway.

2020-06-29spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI*Lukasz Majewski
This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

2020-01-27spi: nxp_fspi: new driver for the FlexSPI controllerMichael Walle
This is a port of the kernel's spi-nxp-fspi driver. It uses the new spi-mem interface and does not expose the more generic spi-xfer interface. The source was taken from the v5.3-rc3 tag. The port was straightforward: - remove the interrupt handling and the completion by busy polling the controller - remove locks - move the setup of the memory windows into claim_bus() - move the setup of the speed into set_speed() - port the device tree bindings from the original fspi_probe() to ofdata_to_platdata() There were only some style change fixes, no change in any logic. For example, there are busy loops where the return code is not handled correctly, eg. only prints a warning with WARN_ON(). This port intentionally left most functions unchanged to ease future bugfixes. This was tested on a custom LS1028A board. Because the LS1028A doesn't have proper clock framework support, changing the clock speed was not tested. This also means that it is not possible to change the SPI speed on LS1028A for now (neither is it possible in the linux driver).

Its been tested on the LinkIt Smart 7688 and the Gardena Smart Gateway with and SPI NOR on CS0 and on the Gardena Smart Gateway additionally with an SPI NAND on CS1. Note that the SPI controller only supports a max transfer size of 32 bytes. This driver implementes a workaround to enable bigger xfer sizes to speed up the transfer especially for the SPI NAND support.

2018-09-25spi: add support for ARM PL022 SPI controllerQuentin Schulz
This adds support for the ARM PL022 SPI controller for the standard variant (0x00041022) which has a 16bit wide and 8 locations deep TX/RX FIFO. A few parts were borrowed from the Linux kernel driver. Cc: Armando Visconti <armando.visconti@st.com> Cc: Vipin Kumar <vipin.kumar@st.com> Signed-off-by: Quentin Schulz <quentin.schulz@bootlin.com>
