List of supported formats grew over time and implementation got a bit
messy. There are multiple functions with format-specific parameters and
commands.
Refactor it by making platform_identify() setup all required info right
after detecting firmware format. This simplifies formats handling in
platform_other_check_image() and platform_do_upgrade() a lot.
This has been tested on:
1. SmartRG SR400ac (TRX): non-NAND sysupgrade
2. Netgear R8000 (CHK): NAND aware and standard sysupgrade-s
3. D-Link DIR-885L (Seama): NAND aware and standard sysupgrade-s
4. Luxul XWR-3150 (LXL): NAND aware and standard sysupgrade-s

SERIAL:
WARNING: The serial port needs a TTL/RS-232 3V3 level converter!
The Serial setting is 115200-8-N-1. The board has a populated
right angle 1x4 0.1" pinheader.
The pinout is: VCC, RX, TX, GND. (Use a multimeter)
Flashing needs a serial adaptor (due to the lack of a working dropbear on
the original firmware).
This flashing procedure for the MR32 was tested with firmware:
"r23-149867:150252-aacharya".
0. Create a seperate Ethernet LAN which does not have access to the internet.
Ideally use 192.168.1.2 for your PC. Make sure to reserve 192.168.1.1 it
will be used later on by the OpenWrt firmware. The original Meraki firmware
will likely try to setup the network via DHCP Discovery, so make sure your
PC is running a DHCP-Server (i.e.: dnsmasq)
'# dnsmasq -i eth# -F 192.168.1.5,192.168.1.50
Furthermore, the PC needs a supported ssh/http/ftp server in order to
retrieve the initramfs + dtb file
1. Disassemble the MR32 device by removing all screws (4 screws are located
under the 4 rubber feets!) and prying open the plastic covers without
breaking the plastic retention clips. Once inside, remove all the screws
on the outer metal shielding to get to the PCB. It's not necessary to
remove the antennas!
2. Connect the serial cable to the serial header.
3. Partially reassemble the outer metal shielding to ensure that the SoC
has a proper heat sink.
4. Connect the Ethernet patch cable to the device and the power cable.
5. Wait for the device to boot and enter the root shell.
(rooting is not discussed in detail here please refer to
Chris Blake - "pwning the meraki mr18" blog post:
<https://servernetworktech.com/2016/02/pwning-the-meraki-mr18/>
(The same method works with the MR32's r23-149867:150252-aacharya)
Wait for the MR32 to enter the "<Meraki>" prompt and enter:
<Meraki> odm serial_num read
(Verify that it matches what's on the S/N Sticker on the back!)
<Meraki> odm serial_num write Q2XX-XXXX-XXXV
<Meraki> odm serial_num read
(Verify that the S/N has changed - and the LED start to flash)
now to flash the firmware:
<Meraki> odm firmware part.safe "http://192.168.1.2/mr32-initramfs.bin"
Once OpenWrt booted use sysupgrade to permanently install
OpenWrt. To do this: Download the latest sysupgrade.bin file
for the MR32 to the device and use sysupgrade *sysupgrade.bin
to install it.
WARNING: DO NOT DELETE the "storage" ubi volume!
To flash later MR32 Firmwares like r25-201804051805-G885d6d78-dhow-rel
requires in-circut-i2c tools to access the I2C EEPROM AT24C64 next to
the SoC. The idea is pretty much the same as from Step 5 from above:
Change the serial number to Q2XXXXXXXXXV (should be around 0x7c), then
attach a serial cable, ethernet (but make sure the device can't reach
the internet!) hit "s" (the small s!) during boot to enter the root-shell
and add the following commands to the /storage/config there:
serial_allow_odm true
serial_access_enabled true
serial_access_check false
valid_config true
and then hit exit to let it finish booting.

Use "truncate" to adjust size of existing file instead of "dd" which
required creating a copy. This saves space on tmpfs. It may be as low
as 2.1 MiB when using OpenWrt default user space and way more (20+ MiB)
when flashing vendor firmware.

Calling nand_do_upgrade() from platform_pre_upgrade() was obsoleted in
the commit 30f61a34b4 ("base-files: always use staged sysupgrade").
This change brings bcm53xx in sync with other targets and allows
dropping backward compatibility code. It shouldn't change any user

Since BusyBox 1.25.0 dd command supports iflag=skip_bytes which allows
skipping requested amount of bytes without reducing blocksize. Thanks to
this we can leave default blocksize and let dd work more efficiently.
On Netgear R6250 "dd skip=58 iflag=skip_bytes" can be 5 times faster
than "dd bs=58 skip=1" when extracting TRX out of CHK.

Depending on busybox applet selection, paths of basic utiilties may differ,
and may not work as symlinks to busybox. Simply using whatever binary is
found in PATH and detecting symlinks automatically is more robust and
easier to maintain.
The list of binaries is also slightly cleaned up and duplicates are
removed.

Extracting TRX to separated file in /tmp/ just wastes some RAM while we

In most cases it allows reverting back to the vendor firmware (as they
usually don't use UBI). If users wants to do that we can't do anything
anyway. Erease counters will be just lost. The only thing we do is warn:
"Flashing firmware without UBI for rootfs. All erase counters will be
lost."
It still requires forcing sysupgrade.

We can now detect that provided firmware contains kernel and UBI image
partitions. Flashing it in a sane way (keeping erase counters) still
needs to be implemented.
