While an image layout based on MBR and 'bootfs' partition may be easy
to understand for users who are very used to the IBM PC and always have
the option to access the SD card outside of the device (and hence don't
really depend on other recovery methods or dual-boot), in my opinion
it's a dead end for many desirable features on embedded systems,
especially when managed remotely (and hence without an easy option to
access the SD card using another device in case things go wrong, for
example).
Let me explain:
* using a MSDOS/VFAT filesystem to store kernel(s) is problematic, as a
single corruption of the bootfs can render the system into a state
that it no longer boots at all. This makes dual-boot useless, or at
least very tedious to setup with then 2 independent boot partitions
to avoid the single point of failure on a "hot" block (the FAT index
of the boot partition, written every time a file is changed in
bootfs). And well: most targets even store the bootloader environment
in a file in that very same FAT filesystem, hence it cannot be used
to script a reliable dual-boot method (as loading the environment
itself will already fail if the filesystem is corrupted).
* loading the kernel uImage from bootfs and using rootfs inside an
additional partition means the bootloader can only validate the
kernel -- if rootfs is broken or corrupted, this can lead to a reboot
loop, which is often a quite costly thing to happen in terms of
hardware lifetime.
* imitating MBR-boot behavior with a FAT-formatted bootfs partition
(like IBM PC in the 80s and 90s) is just one of many choices on
embedded targets. There are much better options with modern U-Boot
(which is what we use and build from source for all targets booting
off SD cards), see examples in mediatek/mt7622 and mediatek/mt7623.
Hence rename the 'sdcard' feature to 'legacy-sdcard', and prefix
functions with 'legacy_sdcard_' instead of 'sdcard_'.

The GL.iNet GL-MV1000 is booting from eMMC and the images for it are in
theory sysupgrade compatible. But the platform upgrade scripts were not
adjusted to select the mmcblock device as upgrade target. This resulted in
a failed sysupgrade because the mtd device (NOR flash) was instead tried to
be modified by the sysupgrade script.

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

This patch adds support for Globalscale ESPRESSObin-Ultra. Device uses
the same Armada-3720 SoC with extended hardware support.
- SoC: Armada-3720
- RAM: 1 GB DDR4
- Flash: 4MB SPI NOR (mx25u3235f) + 8 GB eMMC
- Ethernet: Topaz 6341 88e6341 (4x GB LAN + 1x WAN with 30W PoE)
- WiFI: 2x2 802.11ac Wi-Fi marvell (88w8997 PCIe+USB)
- 1x USB 2.0 port
- 1x USB 3.0 port
- 1x microSD slot
- 1x mini-PCIe slot (USB [with nano-sim slot])
- 1x mini-USB debug UART
- 1x RTC Clock and battery
- 1x reset button
- 1x power button
- 4x LED (RGBY)
- Optional 1x M.2 2280 slot
** Installation **
Copy dtb from build_dir to bin/ and run tftpserver there:
$ cp ./build_dir/target-aarch64_cortex-a53_musl/linux-mvebu_cortexa53/
linux-5.4.65/arch/arm64/boot/dts/marvell/armada-3720-espressobin-ultra.dtb
bin/targets/mvebu/cortexa53/
$ in.tftpd -L -s bin/targets/mvebu/cortexa53/
Connect to the device UART via microUSB port on the back side and power on the device.
Power on the device and hit any key to stop the autoboot.
Set serverip (host IP) and ipaddr (any free IP address on the same subnet), e.g:
$ setenv serverip 192.168.1.10 # Host
$ setenv ipaddr 192.168.1.15 # Device
Ping server to confirm network is working:
$ ping $serverip
Using neta@30000 device
host 192.168.1.15 is alive
Tftpboot the firmware:
$ tftpboot $kernel_addr_r openwrt-mvebu-cortexa53-globalscale_espressobin-ultra-initramfs-kernel.bin
$ tftpboot $fdt_addr_r armada-3720-espressobin-ultra.dtb
Set the console and boot the image:
$ setenv bootargs $console
$ booti $kernel_addr_r - $fdt_addr_r
Once the initramfs is booted, transfer openwrt-mvebu-cortexa53-globalscale_espressobin-ultra-squashfs-sdcard.img.gz
to /tmp dir on the device.
Gunzip and dd the image:
$ gunzip /tmp/openwrt-mvebu-cortexa53-globalscale_espressobin-ultra-squashfs-sdcard.img.gz
$ dd if=/tmp/openwrt-mvebu-cortexa53-globalscale_espressobin-ultra-squashfs-sdcard.img of=/dev/mmcblk0 && sync
Reboot the device.

This fixes a bunch of cosmetic issues with GL.iNet GL-MV1000:
- apply alphabetic sorting in multiple files
- use armada-3720 prefix for DTS like for other devices
- fix vendor capitalization for model in DTSes
- remove trivial comment in DTS files
- use DEVICE_VENDOR/DEVICE_MODEL
- remove redundant SUPPORTED_DEVICES
- use SOC instead of DEVICE_DTS
- remove empty line at EOF

For the mvebu target in particular, there is a lot of files in
base-files that are only relevant for one subtarget. Improve
overview and reduce size per subtarget by moving/splitting
base-files depending on the subtarget they belong to.
While at it, consolidate 01_leds by using the model part of
the board name as variable.
