Subject: ath79: add support for indicating the boot state using multiple leds
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7a873974f7fd04b4d5563df2b7ed91e9be3b38b7;p=openwrt%2Fstaging%2Fxback.git

ath79: add support for indicating the boot state using multiple leds

Use diag.sh version used for apm821xx, ipq40xx and ipq806x, which
supports different leds for the different boot states.

The existing led sequences should be the same as before.
