memory: Add STM32 Octo Memory Manager driver

2025-05-07T09:27:01Z

Octo Memory Manager driver (OMM) manages: - the muxing between 2 OSPI busses and 2 output ports. There are 4 possible muxing configurations: - direct mode (no multiplexing): OSPI1 output is on port 1 and OSPI2 output is on port 2 - OSPI1 and OSPI2 are multiplexed over the same output port 1 - swapped mode (no multiplexing), OSPI1 output is on port 2, OSPI2 output is on port 1 - OSPI1 and OSPI2 are multiplexed over the same output port 2 - the split of the memory area shared between the 2 OSPI instances. - chip select selection override. - the time between 2 transactions in multiplexed mode. - check firewall access.

memory: Simplify 'default' choice in Kconfig

2025-04-15T05:43:53Z

'default y if FOO' can be written shorter (and it already is in other places). Link: https://lore.kernel.org/r/20250404111703.235455-1-krzysztof.kozlowski@linaro.org Signed-off-by: Krzysztof Kozlowski

memory: fsl_ifc: Make FSL_IFC config visible and selectable

2024-06-12T08:17:37Z

While use of fsl_ifc driver with NAND flash is fine, as the fsl_ifc_nand driver selects FSL_IFC automatically, we need the CONFIG_FSL_IFC option to be selectable for platforms using fsl_ifc with NOR flash.

memory: atmel-sdramc: remove the driver

2023-06-02T08:39:24Z

Driver does only clock request + enable for DDR clocks. DDR clocks are enabled by bootloader and need to stay that way in Linux. To avoid having these clocks disabled by clock subsystem in case there are no Linux consumers for them the clocks were marked as critical in clock drivers (in commit 68b3b6f1773d ("clk: at91: mark ddr clocks as critical")). With this, there is no need to have a separate driver that only does clock request + enable.

memory: stm32-fmc2-ebi: depends on ARCH_STM32 instead of MACH_STM32MP157

2023-03-27T16:04:56Z

To be able to compile the driver on all STM32MP SOCs, we move the "depends on" on ARCH_STM32. Signed-off-by: Christophe Kerello Link: https://lore.kernel.org/r/20230324155105.826063-2-christophe.kerello@foss.st.com Signed-off-by: Krzysztof Kozlowski

memory: brcmstb_memc: Add Broadcom STB memory controller driver

2022-08-18T06:11:45Z

Add support for configuring the Self Refresh Power Down (SRPD) inactivity timeout on Broadcom STB chips. This is used to conserve power when the DRAM activity is reduced.

memory: omap-gpmc: OMAP_GPMC should depend on ARCH_OMAP2PLUS || ARCH_KEYSTONE || ARCH_K3

2022-06-06T09:10:53Z

The Texas Instruments OMAP General Purpose Memory Controller (GPMC) is only present on TI OMAP2/3/4/5, Keystone, AM33xx, AM43x, DRA7xx, TI81xx, and K3 SoCs. Hence add a dependency on ARCH_OMAP2PLUS || ARCH_KEYSTONE || ARCH_K3, to prevent asking the user about this driver when configuring a kernel without OMAP2+, Keystone, or K3 SoC family support.

memory: omap-gpmc: Allow building as a module

2022-04-29T06:57:36Z

Allow OMAP_GPMC to be built as a module. When building this driver as a module, the symbol 'of_default_bus_match_table' will not be found as it is not being exported. The of_match_node() call is redundant anyways as of_platform_default_populate() already takes care of matching with 'of_default_bus_match_table'. So get rid of that call. This will also resolve the module build failure. Move compatible match table to the end where it is usually expected.

memory: omap-gpmc: Make OMAP_GPMC config visible and selectable

2022-04-29T06:57:30Z

So far for armv7 TI platforms, GPMC was being selected by arch/arm/mach-* architecture Kconfig files. For K3 platforms, GPMC is no longer required for basic boot and cannot be always enabled by default by mach- Kconfig. We need a way for user (or board defconfig) to enable it if required so make OMAP_GPMC Kconfig option always visible. Drop COMPILE_TEST as build fails if IRQ_DOMAIN is not enabled.
