Christian Lamparter 102009f3ea mpc85xx: p1020: convert Aerohive AP330/AP350 to simpleImage
with 6.1, the kernel no longer fitted into the 16 MiB and
kicking down the can and increasing KERNEL_SIZE to 20 MiB
didn't help as the device failed to boot.

Using 'kernel-bin | gzip | uimage gzip' didn't work since the
uboot does not have enough heap to decompress these big kernels.

And finally playing around with uboot was more a hassle than
converting this device to take the simpleImage-boot-route in
the future.

Note: The device now takes even longer on the first boot-up after
the flash due to JFFS2 initializing all the remaining flash.
Be prepared to wait up to 10 minutes before the green status LED
stops blinking and will shine a solid green!

(On the plus site: the device now has ~10 MiB of additional
space for rootfs+rootfs_data).

Note2: This patch includes a kernel patch refresh.

Subject: [PATCH] powerpc: bootwrapper: disable uImage generation
Due to CONFIG_KERNEL_XZ symbol, the bootwrapper code tries to
instruct the mkimage to use the xz compression, which isn't
supported. This disables the uImage generation, as OpenWrt
generates individual uImages for each board using it's own
toolchain.
