From: Arnd Bergmann <arnd@arndb.de>

There are four MTD maps drivers that are 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, so just remove the drivers entirely.

-** The Embedded Systems BIOS decodes the first FLASH starting at

-** the flash at this location causes the A22 address line to be high
-** (that's what 0x8400000 binary's ought to be). But this is the highest
-** order address line on the raw flash devices themselves!!
-** This causes the top HALF of the flash to be accessed first. Beyond
-** the physical limits of the flash, the flash chip aliases over (to
-** 0x880000 which causes the bottom half to be accessed. This splits the
-** flash into two and inverts it! If you then try to access this from another
-** program that does NOT do this insanity, then you *will* access the
-** first half of the flash, but not find what you expect there. That
-** stuff is in the *second* half! Similarly, the address used by the
-** BIOS for the second FLASH bank is also quite a bad choice.
-** If REPROGRAM_PAR is defined below (the default), then this driver will
-** choose more useful addresses for the FLASH banks by reprogramming the
-** responsible PARxx registers in the SC520's MMCR region. This will
-** cause the settings to be incompatible with the BIOS's settings, which
-** shouldn't be a problem since you are running Linux, (i.e. the BIOS is
-** not much use anyway). However, if you need to be compatible with
-** the BIOS for some reason, just undefine REPROGRAM_PAR.
