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.

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.

This refreshes the current kernel configuration to remove unneeded
options, add some automatically added ones and reorders them. The normal
build did this automatically, so the builds already used this
configuration.
CONFIG_HW_RANDOM_OMAP is explicitly activated for the cortexa72
subtarget because it has an inside-secure,safexcel-eip76 IP core.
This was done with this command on the cortexa9 subtarget:
make kernel_oldconfig
and this one on the other subtargets:
make kernel_oldconfig CONFIG_TARGET=subtarget

This symbol is enabled in all subtargets, move it to common kernel
config.

In 4.14.57, a new symbol for Spectre v4 mitigation was introduced for
ARM64. Add this symbol to all ARM64 targets using kernel 4.14.
This mitigates CVE-2018-3639 on ARM64.

Booting from micro SD card:
1. reset U-Boot environment:
env default -a
saveenv
2. prepare U-Boot with boot script:
setenv bootcmd "load mmc 1:1 0x4d00000 boot.scr; source 0x4d00000"
saveenv
or manually:
setenv fdt_name armada-8040-mcbin.dtb
setenv image_name Image
setenv bootcmd 'mmc dev 1; ext4load mmc 1:1 $kernel_addr $image_name;ext4load mmc 1:1 $fdt_addr $fdt_name;setenv bootargs $console root=/dev/mmcblk1p2 rw rootwait; booti $kernel_addr - $fdt_addr'
saveenv
