Revert "mtd: maps: remove uclinux map driver"

2026-07-03T13:46:28+00:00

The uclinux MTD map driver is still actively used on ColdFire (m68k) platforms. The ColdFire startup code in arch/m68k/coldfire/head.S copies an attached filesystem blob to _bss_stop, and the uclinux driver picks it up from there. Most ColdFire defconfigs enable CONFIG_MTD_UCLINUX, as the driver seems to serve as a replacement for CONFIG_BLK_DEV_INITRD on these non-MMU targets. The driver was removed as part of a series cleaning up AMD Élan specific drivers, but unlike the other three drivers in that series, this driver seemed to not be as Élan specific (nor unused) as initially thought. This reverts commit c584b8a7ad01a334a89732f3c5791ba14e58642b.

mtd: maps: remove obsolete impa7 map driver

2026-05-27T09:19:57+00:00

This driver was originally merged in 2002 for a board using the Cirrus Logic CL/PS711x platform, but the actual board file never made it upstream. The SoC platform is still supported but uses devicetree based probing, so if anyone ever wanted to upstream board support, they would just use the regular physmap driver.

mtd: maps: remove uclinux map driver

2026-05-27T09:19:57+00:00

Rather than using platform data or DT properties, the configuration for this mtd map driver used to be passed through the global uclinux_ram_map structure, but the last instance was removed in commit 4ba66a976072 ("arch: remove blackfin port") in 2018. After commit 251f26c9e828 ("mtd: maps: Make uclinux_ram_map static"), it became impossible to configure it at all, even with out-of-tree platform code. Clearly nobody is using it, so remove it.

mtd: maps: remove AMD Élan specific drivers

2026-05-27T09:19:57+00:00

There were four MTD maps drivers that were used with AMD Élan SoCs. Since 486-class CPU support was removed in commit 8b793a92d862 ("x86/cpu: Remove M486/M486SX/ELAN support"), it is no longer possible to actually use these. Three of them have already been removed, so remove the remaining driver entirely.

mtd: maps: ixp4xx: Drop driver

2022-04-25T08:37:49+00:00

This custom maps driver was never used with the device tree enabled IXP4xx systems, which use the physmap add-on from commit 2aba2f2a704d ("mtd: physmap_of: add a hook for Intel IXP4xx flash probing") Since kernel v5.18-rc1 IXP4xx is only booting from the device tree so drop this old driver.
