> This driver exposes the data encoded in the "hard_config" flash segment
> of MikroTik RouterBOARDs devices. It presents the data in a sysfs folder
> named "hard_config". The WLAN calibration data is available on demand via
> the 'wlan_data' sysfs file in that folder.
> This driver permanently allocates a chunk of RAM as large as the
> "hard_config" MTD partition (typically 4KB), although it is technically
> possible to operate entirely from the MTD device without using a local
> buffer (except when requesting WLAN calibration data), at the cost of a
> performance penalty.
> This driver does not reuse any of the existing code previously found in
> routerboot.c.
> This driver has been successfully tested on BE (ath79) and LE (ipq40xx)
> hardware.
