This patch is backported from linux-arm-kernel [1] to improve situation, when
it was reported that 1.2 GHz variant is unstable with DFS.
It waits to be accepted upstream, however, it waits for Marvell people to respond.

Based on the discussion on the mailing list [1], the patch which was
reverted, it reverts only one patch without the subsequent ones.
This leads to the SoC scaling issue not using a CPU parent clock, but
it uses DDR clock. This is done for all variants, and it's wrong because
commits (hacks) that were using the DDR clock are no longer in the mainline kernel.
If someone has stability issues on 1.2 GHz, it should not affect all
routers (1 GHz, 800 MHz) and it should be rather consulted with guys, who are trying to
improve the situation in the kernel and not making the situation worse.
There are two solutions in cases of instability:
a) disable cpufreq
b) underclock it up to 1 GHz
This reverts commit 080a0b74e3.

This patch has been carried since introduction throughout every kernel
major bump and no one has tested if the later kernels improved the
situation. The Armada 3720 SoC can only process GbE interrupts on Core 0
and this is already limited in all stable kernels, so ditch this
workaround for 64 bit SoCs.

This patch has been added with initial support for ESPRESSObin board and
mistakenly it affects all boards with this SoC. Drop this patch since
the aliases are now in upstream dts for ESPRESSObin. If any boards are
relying on this, please add the respective alias to that board dts.

The crypto engine in Armada 370 SoCs is currently broken. It can be
checked installing the required packages for testing openssl with hw
acceleration:
opkg install openssl-util
opkg install kmod-cryptodev
opkg install libopenssl-devcrypto
After configuring /etc/ssl/openssl.cnf to let openssl use the crypto
engine for digest operations, and performing some checksums..
md5sum 10M-file.bin
openssl md5 10M-file.bin
...we can see they don't match.
There might be an alignment or size constraint issue caused by the
idle-sram area.
Use the whole crypto sram and disable the idle-sram area to fix it. Also
disable the idle support by adding the broken-idle property to prevent
accessing the disabled idle-sram.
We don't care about disabling the idle support since it is already broken
in Armada 370 causing a huge performance loss because it disables
permanently the L2 cache. This was reported in the Openwrt forum and
elsewhere by Debian users with different board models.

mamba has a 3MB kernel partition as specified by the DTS.
3MB is not sufficient for building with many kernel modules or newer
kernel versions.
mamba uboot however as set from factory will load up to 4MB.
This can be observed by looking a uboot log:
NAND read: device 0 offset 0xa00000, size 0x400000
4194304 bytes read: OK
and from uboot environment variables:
$ fw_printenv | grep "pri_kern_size";
pri_kern_size=0x400000
Resize the root partitions from 37MB to 36MB to let kernel expand
into it another 1MB.
And set kernel target size to 4MB.
Lastly add a compatibility version message: kernel-size-migration.
And set it on mamba to prevent sysupgrading without first reinstalling from
a factory image.

It's meant to provide upstream support for mtd & NVMEM. It's required
e.g. for reading MAC address from mtd partition content. It seems to be
in a final shape so it's worth testing.

Also add a new kconfig symbol (CONFIG_KCMP) to the generic config,
disabling the SYS_kcmp syscall (it was split from
CONFIG_CHECKPOINT_RESTORE, which is disabled by default, so the
previous behaviour is kept).

This adds the latest version of ofpart commit. It hopefully
1. Doesn't break compilation
2. Doesn't break partitioning
(this time).
It's required to implement fixed partitioning with some quirks. It's
required by bcm53xx, bcm4908, kirkwood, lantiq and mvebu.
