b3e79e76 - mtd: physmap: Add Baikal-T1 physically mapped ROM support

Sun, 20 Sep 2020 11:14:44 +0000

mtd: physmap: Add Baikal-T1 physically mapped ROM supportBaikal-T1 Boot Controller provides an access to a RO storages, which arephysically mapped into the SoC MMIO space. In particularly there areInternal ROM embedded into the SoC with a pre-installed firmware,externally attached SPI flash (also accessed in the read-only mode) and amemory region, which mirrors one of them in accordance with the currentlyenabled system boot mode (also called Boot ROM).This commit adds the Internal ROM support to the physmap driver of the MTDkernel subsystem. The driver will create the Internal ROM MTD as long asit is defined in the system dts file. The physically mapped SPI flashregion will be used to implement the SPI-mem interface. The mirroringmemory region won't be accessible directly since it's redundant due toboth bootable regions being exposed anyway.Note we had to create a dedicated code for the ROMs since read from thecorresponding memory regions must be done via the dword-aligned addresses.Signed-off-by: Serge Semin Cc: Alexey Malahov Cc: Pavel Parkhomenko Cc: Lee Jones Cc: linux-mips@vger.kernel.orgSigned-off-by: Miquel Raynal Link: https://lore.kernel.org/linux-mtd/20200920111445.21816-1-Sergey.Semin@baikalelectronics.ru List of files: /linux-6.15/drivers/mtd/maps/Kconfig

2aba2f2a - mtd: physmap_of: add a hook for Intel IXP4xx flash probing

Sun, 20 Oct 2019 23:00:42 +0000

mtd: physmap_of: add a hook for Intel IXP4xx flash probingIn order to support device tree probing of IXP4xx NOR flashchips, a certain big-endian or mixed-endian memory accesspattern need to be used.I have opted to use the pattern set by previous plug-insto physmap for Gemini and Versatile, just override somefunctions and reuse most of the physmap core code as itis to minimize maintenance.Parts of drivers/mtd/ixp4xx.c are copied into this file.After we have IXP4xx converted fully to device tree, thedrivers/mtd/ixp4xx.c file will be deleted and this willbe the only access pattern to the IXP4xx flash.I did not keep the quirk in the flash write functionafter probe, where the old code for a while checks foraccess to odd addresses, fails and assigns a "faster"write function once it has convinced probe to only use2-byte accesses. As we mandate that this device shouldbe using bank-width = <2> this should not be a problemunless misconfigured.Signed-off-by: Linus Walleij Signed-off-by: Miquel Raynal List of files: /linux-6.15/drivers/mtd/maps/Kconfig

9d3b5086 - mtd: physmap_of_gemini: Handle pin control

Tue, 27 Nov 2018 20:53:58 +0000

mtd: physmap_of_gemini: Handle pin controlThis enables the complex mapping for the Gemini and kicks incustom read/write functions that will wrap the existingsimple functions in calls to enable/disable the parallelflash pins using pin controls.This is necessary on some hardware such as the D-LinkDIR-685 where all flash pins are patched in/out at the sametime, but some of the flash pins are in practice unused bythe flash and have anyway been reused as GPIO.This concerns specifically CE1 on the Gemini. There is onlyone flash chip, so only CE0 is used, and the line for CE1has been reused as chip select for the emulated SPI portconnected to the display. If we try to use the same linesfor flash and GPIO at the same time, one of them will loose:the GPIO line will disappear because it gets disconnectedfrom 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 lineswhen absolutely necessary (during read/write/copy). Thisway, they are available for GPIO at all other times andthe display works.Collect all the state variables in a struct namedstruct gemini_flash and allocate this struct at probetime.Signed-off-by: Linus Walleij Signed-off-by: Boris Brezillon List of files: /linux-6.15/drivers/mtd/maps/Kconfig

Tue, 26 Jan 2016 10:58:07 +0000

mtd: physmap_of: add a hook for Versatile write protectionIn order to support device tree probing of Versatile NOR flashchips, there must be a way to add the VPP (write protection)enable/disable callback. The register in question is in thesystem controllers of these machines. Apart from this quirk,the ARM flash chips are standard CFI flash chips from variousvendors.Additionally, the Integrator/AP require you to set up the externalbus interface (EBI) to allow writes to the chip select where theflash memory is connected.Solve this by looking for the arm,versatile-flash compatiblestring in the flash device tree node. In the driver,add a special hook to check for the various Versatile syscons andregister a callback for .set_vpp() if this compatible is present.Provide a special Kconfig entry for the addon hook so it willnot be compiled in if the Versatile boards are not supported.Stubs in the header file make sure the impact will be zero onother platforms. (Compilers optimze this out.)With this patch, a large slew of ARM board file code can beremoved.Cc: Grant Likely Cc: Rob Herring Cc: Arnd Bergmann Signed-off-by: Linus Walleij List of files: /linux-6.15/drivers/mtd/maps/Kconfig
