[OpenWrt-Devel] [PATCH 1/2] brcm2708: boot-part feature integration

[Christian Lamparter]

This patch adds the boot-part feature which enables the brcm2708
target move from the custom boot partition size config option to
the generic CONFIG_TARGET_KERNEL_PARTSIZE.

Note:
For people using custom images: Just like with
CONFIG_TARGET_ROOTFS_PARTSIZE changing the value
can cause sysupgrade to repartition the device!
Make sure to have a backup in this case.
