mtd: physmap_of: fixup gemini/versatile dependencies

2017-02-10T17:53:41+00:00

physmap_of sort of depends on the gemini and versatile modules (when they're enabled), but this isn't expressed in Kconfig. Let's just merge the modules all together, when enabled. Then we can avoid exporting a few symbols, and the versatile and gemini code can now be modular again (the below commit accidentally made them built-in only). Resolves errors like this: ERROR: "of_flash_probe_versatile" [drivers/mtd/maps/physmap_of.ko] undefined! ERROR: "of_flash_probe_gemini" [drivers/mtd/maps/physmap_of.ko] undefined!

mtd: physmap_of: add a hook for Gemini flash probing

2017-02-08T21:01:00+00:00

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.

physmap_of: ensure versatile code is reachable

2016-04-25T23:13:55+00:00

With the newly added physmap_of_versatile code, we get a build error when physmap_of is in a module, because of_flash_probe_versatile is not exported: ERROR: "of_flash_probe_versatile" [drivers/mtd/maps/physmap_of.ko] undefined! This adds the export, and changes the Makefile so that the code is also put into a loadable module rather than built-in when physmap_of itself is a module. Signed-off-by: Arnd Bergmann

mtd: physmap_of: add a hook for Versatile write protection

2016-04-04T08:33:16+00:00

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: remove obsolete JEDEC mapping drivers

2013-08-05T20:01:08+00:00

JEDEC device support was removed in v2.6.22. (It had been marked as BROKEN (indirectly) since at least v2.6.12.) When it was removed the two JEDEC mapping drivers that depended on it should have been removed too. Do so now.
