Jeff Kletsky b3770eaca3 mtd: base-files: Unify dual-firmware devices (Linksys) ... 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` Runtime-tested: Linksys EA8300 Signed-off-by: Jeff Kletsky <git-commits@allycomm.com> Signed-off-by: Christian Lamparter <chunkeey@gmail.com> [checkpatch.pl fixes, traded split strings for 80+ chars per line]		2019-05-18 13:43:51 +02:00
