# Based on linux-lg-mako. Changes:
|
||
|
|
# - add findutils makedepend (necessary for the initramfs)
|
||
|
|
# - it builds an initramfs - do not use ramdisk.cpio and
|
||
|
|
# ramdisk-recovery-device.cpio, in there, always use the
|
||
|
|
# initramfs from the recovery partition ("isorec")
|
||
|
|
# - directly boot to that initramfs, not only when the recovery
|
||
|
|
# key combination was pressed.
|
||
|
|
# - use Alpine's busybox-static instead of the pre-compiled
|
||
|
|
# binary, that comes with the source
|
||
|
|
#
|
||
|
|
# Kernel config changes, based on: arch/arm/configs/latona_defconfig
|
||
|
|
# - enable devtmpfs (needed for udev -> touch support in weston)
|
||
|
|
# - change compression from CONFIG_KERNEL_LZMA=y to
|
||
|
|
# CONFIG_KERNEL_GZIP=y (so it works with busybox)
