Consistently handle boot-count reset and upgrade across
ipq40xx, ipq806x, kirkwood, mvebu
Dual-firmware devices often utilize a specific MTD partition
to record the number of times the boot loader has initiated boot.
Most of these devices are NAND, typically with a 2k erase size.
When this code was ported to the ipq40xx platform, the device in hand
used NOR for this partition, with a 16-byte "record" size. As the
implementation of `mtd resetbc` is by-platform, the hard-coded nature
of this change prevented proper operation of a NAND-based device.
* Unified the "NOR" variant with the rest of the Linksys variants
* Added logging to indicate success and failure
* Provided a meaningful return value for scripting
* "Protected" the use of `mtd resetbc` in start-up scripts so that
failure does not end the boot sequence
* Moved Linksys-specific actions into common `/etc/init.d/bootcount`
For upgrade, these devices need to determine which partition to flash,
as well as set certain U-Boot envirnment variables to change the next
boot to the newly flashed version.
* Moved upgrade-related environment changes out of bootcount
* Combined multiple flashes of environment into single one
* Current-partition detection now handles absence of `boot_part`

[checkpatch.pl fixes, traded split strings for 80+ chars per line]
RAMFS_COPY_* are moved to platform.sh toplevel. The nand_do_upgrade call is
moved to platform_do_upgrade.

This automatically writes to the alternate firmware partition
(on Linksys's dual firmware layout) using code borrowed from
the WRT1900AC port.
