Broadcom's U-Boot contains environment data blocks. They need to be
found (offsets aren't predefined) to access env variables.

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.

1. Create "rootfs_data" dynamicaly
U-Boot firmware images can contain only 2 UBI volumes: bootfs (container
with U-Boot + kernel + DTBs) and rootfs (e.g. squashfs). There is no way
to include "rootfs_data" UBI volume or make firmware file tell U-Boot to
create one.
For that reason "rootfs_data" needs to be created dynamically. Use
preinit script to handle that. Fire it right before "mount_root" one.
2. Relate "rootfs_data" to flashed firmware
As already explained flashing new firmware with U-Boot will do nothing
to the "rootfs_data". It could result in new firmware reusing old
"rootfs_data" overlay UBI volume and its file. Users expect a clean
state after flashing firmware (even if flashing the same one).
Solve that by reading flash counter of running firmware and storing it
in "rootfs_data" UBI volume. Every mismatch will result in wiping old
data.

BCM4908 devices with U-Boot use pkgtb firmware format. It's based on
U-Boot's FIT: DTB with configurations, images & embedded data.
This format contains bootfs, rootfs and optionally a first stage U-Boot
loader. Contained images need to be extracted & flashed.
Broadcom used two sets of firmwares: main & backup. It uses UBI volumes
"metadata1" & "metadata2" for storing U-Boot env variables with info
about flashed images.

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.

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
