Subject: apm821xx: use nested fixed-partitions
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d65bafa34bc57f652800cf0f6e6402ff7dca0289;p=openwrt%2Fstaging%2Frmilecki.git

apm821xx: use nested fixed-partitions

This makes it possible to fix Netgear WNDAP620+660 DTS ugliness.
Bring back the dtb and firmware partitions for the WNDR4700.
Thank you, mans0n.
