New BCM4908 family based routers will use U-Boot bootloader. That will
require using a totally different firmware format. Kernel has to be put
in a FIT image.
OpenWrt has some helpers for generating .its files but they don't fit
BCM4908 requirements and there is no simple way of extending any of
them. The best solution seems to be storing an .its template.
BCM4908 bootfs may:
1. contain extra binaries (other than kernel & DTB)
2. include multiple DTB files
3. store device specific U-Boot configurations with custom properties
Such setups are too complex to generate using shell script. Raw .its
file on the other hand seems quire clean & reasonable.

CONFIG_COMPAT_32BIT_TIME is a new symbol and has to be set to avoid:
Provide system calls for 32-bit time_t (COMPAT_32BIT_TIME) [N/y/?] (NEW)
CONFIG_RELOCATABLE needs to be enabled to make kernel start booting.
That raises a question: do we really need CONFIG_EXPERT=y ?

In the current state, nvmem cells are only detected on platform device.
To quickly fix the problem, we register the affected problematic driver
with the of_platform but that is more an hack than a real solution.
Backport from net-next the required patch so that nvmem can work also
with non-platform devices and rework our current patch.
Drop the mediatek and dsa workaround and rework the ath10k patches.
Rework every driver that use the of_get_mac_address api.

This enables building BCM4908 "raw" image that can be flashed using
bootloader web UI. It requires serial console access & stopping booting
by the "Press any key to stop auto run".
It's easy to build vendor like CHK image but it can't be safely flashed
using vendor UI at this point. Netgear implements method called "NAND
incremental flashing" that doesn't seem to flash bootfs partition as
provided.
Above method seems to update vmlinux.lz without updating 94908.dtb. It
prevents OpenWrt kernel from booting due to incomplete DTB file. Full
Netgear R8000P support can be enabled after finding a way to make vendor
firmware flash OpenWrt firmware including the 94908.dtb update.

bcm4908img is a tool managing BCM4908 platform images. It's used for
creating them as well as checking, modifying and extracting data from.
It's required by both: host (for building firmware images) and target
(for sysupgrade purposes). Make it a host/target package.

It supports flashing OpenWrt images (bootfs & UBI upgrade) as well as
vendor images (whole MTD partition write).
Upgrading cferom is unsupported. It requires copying device specific
data (like MAC) to target image before flashing.

This way MTD "bootfs" partition will be always 8+ MiB. This should be
enough for any custom / future firmware to fit its bootfs (e.g. big
kernel) without having to repertition whole flash. That way we can
preserve UBI and its erase counters during sysupgrade.

The purpose of that dummy file is to make CFE work properly with OpenWrt
bootfs. CFE for some reason ignores JFFS2 files with ino 0.
Rename it to 1-openwrt so:
1. It's consistent with bcm63xx
2. It's OpenWrt specific so sysupgrade can distinguish it from vendor
images

So far, board.d files were having execute bit set and contained a
shebang. However, they are just sourced in board_detect, with an
apparantly unnecessary check for execute permission beforehand.
Replace this check by one for existance and make the board.d files
"normal" files, as would be expected in /etc anyway.
Note:
This removes an apparantly unused '#!/bin/sh /etc/rc.common' in
target/linux/bcm47xx/base-files/etc/board.d/01_network

We so far had two variables IMG_PREFIX and IMAGE_PREFIX with
different content. Since these names are obviously quite
confusing, this patch renames the latter to DEVICE_IMG_PREFIX,
as it's a device-dependent variable, while IMG_PREFIX is only
(sub)target-dependent.
For consistency, also rename IMAGE_NAME to DEVICE_IMG_NAME, as
that's a device-dependent variable as well.

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.

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.
