If the SPI probe is sufficiently delayed, the routerboot driver may fail
to init as the routerboot partitions are not yet available.
Register an MTD user notifier instead of doing straight init so that the
init subroutines are only executed when the target MTD partitions are
present.
Because the init/exit routines can now be called outside of the kernel
normal init/exit calls, they cannot be jettisoned and must always be
available: the __init and __exit qualifiers are thus removed.

Make soft_config writable in all cases. Performing soft_config commit
will fail if mtd partition is not writable.

The code uses get_mtd_device_nm() which must be followed by a call to
put_mtd_device() once the handle is no longer used.
This fixes spurious shutdown console messages such as:

This patch adds cpu frequency setting for AR724x and AR7161.
It is unknown if all the AR71xx devices support the same value range,
so support is only enabled for AR7161 at this stage.

The current code would return an error on ath79 when the SoC isn't known
to the driver. Return the raw hex value instead, as happens with non
supported targets.
Also return the correctly incremented value from
sc_tag_cpufreq_ath79_arraysize()

RouterBOOT cpu frequency settings are letter-indexed. Follow the
same logic for the sysfs interface.

This commit introduces support for R/W access to the CPU frequency
setting of routerboot on ath79 hardware.
On unsupported hardware, the sysfs attribute will expose the raw tag
value (read-only) to help with reverse engineering its meaning.

This driver exposes the data encoded in the "soft_config" flash segment
of MikroTik RouterBOARDs devices. It presents the data in a sysfs folder
named "soft_config" through a set of human-and-machine-parseable
attributes. Changes can be discarded by writing 0 to the 'commit'
attribute, or they can be committed to flash storage by writing 1.
This driver does not reuse any of the existing code previously found in
the "rbcfg" utility and makes this utility obsolete by providing a clean
sysfs interface.
Like "rbcfg", this driver requires 4K_SECTORS support since the flash
partition in which these parameters are stored is typically 4KB in size.
