The most affecting change is move of files from bcm4908/ to the bcmbca/.
That required updating few paths.

In theory we could have just 1 bootfs image for all devices as each
device has its own entry in the "configurations" node. It doesn't work
well with default configuration though.
If something goes wrong U-Boot SPL can be interrupted (by pressing A) to
enter its minimalistic menu. It allows ignoring boardid. In such case
bootfs default configuration is used.
For above reason each SoC family (BCM4908, BCM4912) should have its own
bootfs built. It allows each of them to have working default
configuration.

bootfs still needs more work before it's ready.
For some unknown reason model RAXE500 uses board id RAX220.

It still isn't ready though - more data needs to be added to the bootfs.

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.

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.

OpenWrt was succesfully tested on the GT-AC5300 model. It's possible to:
1. Install OpenWrt using vendor UI
2. Perform UBI aware sysupgrade
3. Install vendor firmware using OpenWrt sysupgrade

(cherry picked from commit 5e78cb9b85)
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

It's a BCM4906 based device (2 CPU cores). It has 512 MiB of RAM, 4 LAN
ports, 1 WAN port, 2 USB ports, NAND flash. WiFi unknown at this point.
Flashing is possible using CFE only, proper image will be worked on
later.

and moves the DEVICE_VARS to the top like common on several other

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.

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.
