With transition from ar71xx to ath79 some of devices change their naming
of LEDs. When upgrading from ar71xx target images this will require the
user to adjust previously working configuration. This commit adds
migration script which can be used to rename old names to new ones.
With this previously working configuration will be automatically
adjusted, wihtout user intervention.
This commit adds migration case for EnGenius EPG5000, the wireless LEDs

TrimSlice uses U-Boot placed in NOR flash. Boots Linux from any media
connected to USB, SATA or SD card inserted in slot. Can also boot from
TFTP. To run OpenWrt one needs to update U-Boot to fairly recent version
(the versions, pre-dts/dts provided by CompuLab won't suffice):
1. Boot TrimSlice into Your current linux distro,
2. Download trimslice-spi.img from u-boot-trimslice subdir,
3. Install mtd-utils,
4. Run following commands:
flash_erase /dev/mtd0 0 256
nandwrite /dev/mtd0 trimslice-spi.img
5. Poweroff, insert SD card with OpenWrt, boot and enjoy.
If by some obstacle You can't follow those instructions, it is possible
to flash U-Boot using serial console.
1. Insert FAT or EXT2/EXT3 formatted SD card with trimslice-spi.img,
2. Interrupt boot process to enter U-Boot command line,
3. Run following commands:
${fs}load mmc 0 0x04080000 trimslice-spi.img
sf probe 0
sf erase 0 0x100000
sf write 0x04080000 0x0 ${filesize}
reset
4. Poweroff, insert SD card with OpenWrt, boot and enjoy.
If something went wrong with one of above steps, there is simple
recovery option:
1. Open the µSD slot security door to access the recovery-boot button,
2. Insert SD card with OpenWrt to the front slot while unpowered,
3. Power on the TrimSlice while pressing the recovery-boot button,
4. With this it should boot straigth to OpenWrt, from there download
trimslice-spi.img and execute following commands:
mtd erase /dev/mtd0
mtd write trimslice-spi.img /dev/mtd0
5. Reboot, now it should boot straigth to OpenWrt, without pressing the
recovery-boot button, with proper U-Boot flashed.

The target ENS202EXT was just recently added right before the stable
release of Openwrt 18.
It flashes fine, but the physical switch is almost impossible to use
until you have a VLAN set up. Tested on two devices.
The actual problem is that eth0 represents nothing for whatever reason.
In other words, both WAN and LAN are running from eth1. There may be an
underlying problem in the build, but for now, I assume that this is
correct and that a VLAN switch is an appropriate fix.
Also, it's virtually impossible to get the switch running right through
LuCI. It is one thing to get a switch to appear, but attempting to
configure it breaks the whole thing. The VLAN has to be set up
perfectly, otherwise, interfaces will not start up, and one is forced to
reset settings, OR, the new LuCI feature kicks in and reverses any
steps. It is extremely difficult to determine which virtual ports
correspond to which physical ethernet ports without being able to set up
the switch in LuCI.
