Hauke Mehrtens 46af22de16 kernel: Remove CONFIG_COMPAT
This removes support for executing old 32 bit applications on 64 bit ARM
and MIPS kernels.
On OpenWrt we normally compile all the user space applications on our
own and do not support third party binary only modules especial not 32
bit applications on 64 bit CPUs.

This reduces the attack surface on such systems and should also save
some memory.

Hauke Mehrtens 32eb66881c kernel: Activate CONFIG_ARM64_SW_TTBR0_PAN
This activates "Emulate Privileged Access Never using TTBR0_EL1
switching" on ARM64.

This should prevent the kernel from reading code from user space in
kernel context.

Make I2C built-in instead of modular as in upstream defconfig; also the
easiest way to get MFD_ARIZONA enabled, which is required by
kmod-sound-soc-rpi-cirrus.
Add missing compatible strings from
4.9/960-add-rasbperrypi-compatible.patch, using upstream names for
compute modules.
Add extra patch to enable the LEDs on lan78xx.

Christian Lamparter 707b6c815b brcm2708: add squashfs rootfs image
This patch adds a image with squashfs as the root filesystem.
A rootfs_data partition will be generated on the first boot
and placed inside the rootfs partition (just after the squashfs
image).

advantages:
 - it is possible to migrate from an existing -ext4
   installation and back via sysupgrade.
 - existing partition layout will not be lost.
 - slightly smaller image size.
 - support for attendedsysupgrade

disadvantages:
 - needs f2fs + tools as well. This is because fs-tools decides on the
   blocksize of the sdcard. So either f2fs or ext4 can get choosen as
   the rootfs_data filesystem (depends on the size of the root partition).
 - rootfs_data is placed into the rootfs partition. This makes
   it difficult for tools that expect a /dev/mmc0pX device.
   It also makes it difficult for data recovery tools since they
   might not expect to find a embedded partition or will be
   confused.

For people with existing build configurations: make sure to include mkf2fs
and f2fsck package into the image... Otherwise the new -squashfs image will
boot of a ram-overlay and won't keep the configurations after a reboot.

Stijn Tintel c454fab0f2 brcm2708: enable cpufreq
With cpufreq disabled, the CPU stays locked at the frequency set by the
bootloader. This severely degrades performance as the bootloader sets
the CPU at the lowest frequency by default.

Enable cpufreq for all subtargets and use the ondemand governor.
