Subject: apm821xx: sata: boot-part feature integration
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=257de1b01f985a96a08ba26f2feb5cffec89b911;p=openwrt%2Fstaging%2Fansuel.git

apm821xx: sata: boot-part feature integration

This patch adds the boot-part feature to the apm82181 sata target.
This makes it possible to configure the boot partition size with
the generic CONFIG_TARGET_KERNEL_PARTSIZE symbol.

Please note: For people using custom images: Just like with
CONFIG_TARGET_ROOTFS_PARTSIZE changing the value can cause
sysupgrade to repartition the device!
