20b4f77bb6 kernel: add parser finding rootfs after CFE bootfs
It's required for BCM4908. It cannot use "bcm-wfi-fw" parser because
that one requires *two* JFFS2 partitions which is untested / unsupported
on the BCM4908 architecture. With a single JFFS2 partition "bcm-wfi-fw"
parser will:
1. Fail to find "vmlinux.lz" as it doesn't follow "1-openwrt" file
2. Create partitions that don't precisely match bootfs layout

The new parser is described in details in the MTD_SPLIT_CFE_BOOTFS
symbol help message.

3bd8f660a4 bcm4908: workaround NAND controller #WP issue
There seems to be a problem with setting #WP. On the other hand ignoring
the #WP seems to work. rootfs_data UBI volume seems to persist changes.

4e1e18af65 bcm4908: build flashable & bootable firmware images
BCM4908 bootloader requires firmware with JFFS2 image containing:
1. cferam.000
2. 94908.dtb
3. vmlinux.lz
4. device custom files

cferam.000 can be obtained from the bcm63xx-cfe repository.
device custom files are stored in images dir.

095ed5e8e1 bcm4908: set console in the CONFIG_CMDLINE
procd doesn't work with just serial specified in the DT (using chosen &
stdout-path). It requires tty device to be explicitly specified in the
cmdline.

c578fdfc29 bcm4908: initial work on the Broadcom BCM4908 target
BCM4906, BCM4908 and BCM49408 are SoCs with 64 bit ARMv8 B53 CPUs.
Upstream Linux is slowly getting support for that SoCs family so it
makes sense to add target for it.

This prepares initial support for:

1. Asus GT-AC5300
BCM4908 based device (4 CPUs) with 1024 MiB RAM, NAND, 8 LAN ports.

2. Netgear R8000P
BCM4906 based device (2 CPUs) with 512 MiB RAM, NAND, 4 LAN ports.

Flashing info will come later as we learn how to generate proper images.

It isn't usable yet (it only produces a bootable kernel) so "source-only"
is used.
