drivers: memc: stm32: initial support for stm32 FMC This commit adds a new driver category for memory controller peripherals. There is no API involved for now, as it has not been found necessary for first implementation. STM32 Flexible Memory Controller (FMC) is the only controller supported for now. This peripheral allows to access multiple types of external memories, e.g. SDRAM, NAND, NOR Flash... The initial implementation adds support for the SDRAM controller only. The HAL API is used, so the implementation should be portable to other STM32 series. It has only been tested on H7 series, so for now it can only be enabled when working on H7. Linker facilities have also been added in order to allow applications to easily define a variable in SDRAM. Signed-off-by: Gerard Marull-Paretas <gerard@teslabs.com>

We remove 'depend on' Kconfig for symbols that would be implied by the devicetree node existing. Signed-off-by: Kumar Gala <galak@kernel.org>

drivers: memc: fix Kconfig option MEMC_STM32 This commit fixes a bug with the declaration of the Kconfig option MEMC_STM32. The option is defined in two files: - `drivers/memc/Kconfig.stm32`, wich depends on - `MEMC` - `DT_HAS_ST_STM32_FMC_ENABLED` -`soc/st/stm32/Kconfig.defconfig`, wich depends on - `MEMC` - `SOC_FAMILY_STM32` So, if you have `CONFIG_MEMC=y` in your Kconfig options and you are on a STM32 SoC, `CONFIG_MEMC_STM32` will be enabled, even if there is no STM32 FMC enabled. This Kconfig option causes the driver for the STM32 FMC to be compiled, regardless of the presence of an enabled node for the FMC. However, the driver fails to compile if there is no FMC node in the devicetree. So, if you compile a project with `CONFIG_MEMC=y` on a board with an STM32 SoC and no enabled FMC, the build will fail. This commit deletes the Kconfig declaration in the `Kconfig.defconfig`, as it isn't useful and is the one provoking the bug. It also add in the `Kconfig.stm32` the compatible `st,stm32h7-fmc`, wich use the same driver and so need to be enabled by the same Kconfig option.
