* mtd: physmap: Add Baikal-T1 physically mapped ROM supportSerge Semin2020-10-021-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | Baikal-T1 Boot Controller provides an access to a RO storages, which are physically mapped into the SoC MMIO space. In particularly there are Internal ROM embedded into the SoC with a pre-installed firmware, externally attached SPI flash (also accessed in the read-only mode) and a memory region, which mirrors one of them in accordance with the currently enabled system boot mode (also called Boot ROM). This commit adds the Internal ROM support to the physmap driver of the MTD kernel subsystem. The driver will create the Internal ROM MTD as long as it is defined in the system dts file. The physically mapped SPI flash region will be used to implement the SPI-mem interface. The mirroring memory region won't be accessible directly since it's redundant due to both bootable regions being exposed anyway. Note we had to create a dedicated code for the ROMs since read from the corresponding memory regions must be done via the dword-aligned addresses.

* mtd: physmap_of: add a hook for Intel IXP4xx flash probingLinus Walleij2019-10-291-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to support device tree probing of IXP4xx NOR flash chips, a certain big-endian or mixed-endian memory access pattern need to be used. I have opted to use the pattern set by previous plug-ins to physmap for Gemini and Versatile, just override some functions and reuse most of the physmap core code as it is to minimize maintenance. Parts of drivers/mtd/ixp4xx.c are copied into this file. After we have IXP4xx converted fully to device tree, the drivers/mtd/ixp4xx.c file will be deleted and this will be the only access pattern to the IXP4xx flash. I did not keep the quirk in the flash write function after probe, where the old code for a while checks for access to odd addresses, fails and assigns a "faster" write function once it has convinced probe to only use 2-byte accesses. As we mandate that this device should be using bank-width = <2> this should not be a problem unless misconfigured.

* mtd: physmap_of_gemini: Handle pin controlLinus Walleij2018-12-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This enables the complex mapping for the Gemini and kicks in custom read/write functions that will wrap the existing simple functions in calls to enable/disable the parallel flash pins using pin controls. This is necessary on some hardware such as the D-Link DIR-685 where all flash pins are patched in/out at the same time, but some of the flash pins are in practice unused by the flash and have anyway been reused as GPIO. This concerns specifically CE1 on the Gemini. There is only one flash chip, so only CE0 is used, and the line for CE1 has been reused as chip select for the emulated SPI port connected to the display. If we try to use the same lines for flash and GPIO at the same time, one of them will loose: the GPIO line will disappear because it gets disconnected from the pin when the flash group is muxed out. Fix this by introducing two pin control states named simply "enabled" and "disabled" and only enable the flash lines when absolutely necessary (during read/write/copy). This way, they are available for GPIO at all other times and the display works. Collect all the state variables in a struct named struct gemini_flash and allocate this struct at probe time.

| | | | | | | | | | | | | | | Controlling some MSB address lines using GPIOs is just a small deviation from the generic physmap logic, and merging those two drivers allows us to share most of the probe logic, which is a good thing. Also, the gpio-addr-flash driver is unused since the removal of the blackfin arch in v4.17, so we can safely remove the old driver without risking breaking existing boards.

* mtd: physmap_of: add a hook for Gemini flash probingLinus Walleij2017-02-081-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to support device tree probing of Gemini NOR flash chips, a certain register in the syscon needs to be poked to enable parallel flash mode. Such things used to happen in "necessarily different" board file code, and this indeed was also done for the Gemini, so the MTD driver could treat it as any memory-mapped NOR flash, but this is not the way in the future: board files need to go, and hardware concerns distributed down to the applicable drivers. This adds a hook in the same way that the Versatile did: if the Kconfig symbol is not selected the net total of supporting Gemini should be zero bytes of added code. To live up to this promise, also the return value error print from the Versatile extra probe call get to be removed in this patch, all printing need to happen in the add-ons.

* mtd: physmap_of: add a hook for Versatile write protectionLinus Walleij2016-04-041-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to support device tree probing of Versatile NOR flash chips, there must be a way to add the VPP (write protection) enable/disable callback. The register in question is in the system controllers of these machines. Apart from this quirk, the ARM flash chips are standard CFI flash chips from various vendors. Additionally, the Integrator/AP require you to set up the external bus interface (EBI) to allow writes to the chip select where the flash memory is connected. Solve this by looking for the arm,versatile-flash compatible string in the flash device tree node. In the driver, add a special hook to check for the various Versatile syscons and register a callback for .set_vpp() if this compatible is present. Provide a special Kconfig entry for the addon hook so it will not be compiled in if the Versatile boards are not supported. Stubs in the header file make sure the impact will be zero on other platforms. (Compilers optimze this out.) With this patch, a large slew of ARM board file code can be removed.

| * mtd: Drop FORTUNET supportAlexander Shiyan2012-11-221-7/+0
| | | | | | | | | | | | | | | | The kernel has never contained the symbol SA1100_FORTUNET so the driver never compiled and can be removed safely. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

* mtd: allow uclinux map driver to be used on any ColdFire CPU platformGreg Ungerer2012-09-291-1/+1
| | | | | | | | | | | | | | | | | The uclinux.c map driver has traditionally been used only on non-MMU based systems. But there is no fundamental reason it can't be used on systems running with virtual memory. Some ColdFire CPU based systems now have full paged MMU hardware and can use the uclinux.c mapping driver, so making the uclinux.c driver configuration depend on !CONFIG_MMU doesn't make sense now. Allow the CONFIG_MTD_UCLINUX option to be enabled if CONFIG_COLDFIRE is enabled. (I have chosen not to just more generally allow uclinux.c for any MMU type to keep this option hidden for most systems that are not interested in setting it).

* mtd: autcpu12-nvram: Convert driver to platform_deviceAlexander Shiyan2012-09-291-1/+1
| | | | | | | | | | Because we can have a single kernel to support multiple machines, we need to make loading specific drivers for the target platform only. For this, driver is converted to the platform driver.

* mtd: delete SBC82xx/SBC8560 MTD mapping supportPaul Gortmaker2012-07-061-12/+0
| | | | | | | | | | | | | The SBC8260 support was dropped back when we moved from ppc to powerpc. We are now also dropping the support for the EOL SBC8560, so we can also delete this mapping support, as they were the only users of it. Artem: also remove the symbol from the Makefile.

| | | | | | | | | | | | Recent BCM63XX devices support a variety of flash types (parallel, SPI, NAND) and share the partition layout. To prevent code duplication make the CFE partition parsing code a stand alone mtd parser to allow SPI or NAND flash drivers to use it.
