I have just found out that I need to perform this additional step on this
SamKnows Whitebox 8 every boot:
/usr/sbin/fw_setenv bootcount 0
Where would be an appropriate place to put this? I could add (yet another)
init script in ./target/linux/ramips/base-files/etc/init.d with START=99
(this is how SamKnows does it) and add a check against $(ramips_board_name).
Without this, SamKnows' custom u-boot will attempt to boot from a backup
partition after bootcount exceeds 3 (3 "failed" boots).
For an end-user without TTL serial access, it would be a soft brick.
I'm cleaning up the rest of the patches, fixed some minor gpio
mis-definitions and testing out some wifi fixes before I do a v5.

Hi,
few comments inline. apart from those 2 nitpicks the patch looks good.
