d5f9c6729f bcm4908: start working on Netgear RAXE500 image
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.

027dd3c50b bcm4908: start work on images for devices using U-Boot
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.

cc51d97200 bcm4908: enable Netgear R8000P bootloader image
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.

541db110bb bcm4908: enable target & Asus GT-AC5300 image
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

b7ffeef924 bcm4908: pad firmware image bootfs JFFS2 partition to 8 MiB
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.

d91054a521 bcm4908: rename bootfs dummy file to the 1-openwrt
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

bc2c3d99c8 bcm4908: prepare to support TP-Link Archer C2300 V1
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.

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.

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.
