UniElec devices are the last ones in ramips target still having
the RAM size in device name although RAM size is auto-detected.
Remove this from device name, compatible, etc., as it's not

This moves the almost identical calibration data extraction
functions present multiple times in several targets to a single
library file /lib/functions/caldata.sh.
Functions are renamed with more generic names to merge different
variants that only differ in their names.
Most of the targets used find_mtd_chardev, while some used
find_mtd_part inside the extraction code. To merge them, the more
abundant version with find_mtd_chardev is used in the common code.

2 programable radio (blue)
1 programable WPS-5G (blue)
1 non-programable WAN activity (blue)
1 unconfigured WPS-2.4G (amber)
- Buttons: GPIO: Reset, WPS
Installation:
Use the OEM web interface to install the ...-factory.dlf image.
Use the OpenWRT ...-sysupgrade.bin image for future upgrades.
The J2 serial port can be accessed either by soldering in a header,
standard 0.1" spacing, or by using pogo-pins against the back side.
As configured by the OEM, the U-Boot boot delay is short, however quickly
typing "1" leads to the U-Boot "System load Linux to SDRAM via TFTP"
prompt. The TFTP client is configured by default with
client: 192.168.99.9
server: 192.168.99.8
filename: uImageESR600
It will load an OpenWRT initramfs kernel with this method.
Known issues:
1) Only the ports externally labeled WAN, LAN3 and LAN4 are operational.
LAN1 and LAN2 do not appear to power up. This issue is also present
in the Lava LR25G001.
2) The amber WPS-2.4G LED, in the same lightguide as the blue WPS-5G LED,
is not configured in the Device Tree specification.
3) The blue WAN activity LED is not configured in the Device Tree
specification as this causes the AR8327 switch to fail to initialize.

This patch adds the label MAC address for several devices in
ramips.
Some devices require setting the MAC address in 02_network:
For the following devices, the netif device can be linked in
device tree, but the MAC address cannot be read:
- cudy,wr1000
- dlink,dir-615-d
- dlink,dir-615-h1
- dlink,dir-860l-b1
- glinet,gl-mt300a

- glinet,gl-mt750
- vocore,vocore2
- vocore,vocore2-lite
- zbtlink,zbt-we1326
- zbtlink,zbt-wg3526
For the following devices, label MAC address is tied to lan or
wan, so no node to link to exists in device tree:
- dlink,dir-510l
- dlink,dwr-116-a1
- dlink,dwr-118-a1
- dlink,dwr-118-a2

So far, MAC address setup for those devices has been using local
addresses although additional MAC addresses are available on flash.
On device, we found the following situation:
position Y1 Y1S
0x4 *:d4 *:e4
0x8004 *:d6 *:e8
0x28 *:d4 *:e4
0x2e *:d7 *:eb
Since 0x4 and 0x28 yield the same address, the former was set for
ðernet in DTS. However, the typical location on this
architecture is 0x28, so this patch changes that.
For further setup in 02_network, the local bit for lan_mac is
removed, so the address from ðernet is used at all. For wan_mac,
instead of calculating an address with local bit set, this patch
exploits the previously unused address in 0x2e.

This patch removes unnecessary MAC address setup statements in
ramips' 02_network by doing several optimizations:
1. For the following devices, lan_mac was set up with
mtd_get_mac_binary although the same address was set in DTS.
The lan_mac statement is removed in 02_network, but
wan_mac is kept:
- mercury,mac1200r-v2
- phicomm,k2g
- skylab,skw92a
- wiznet,wizfi630a
2. For the following devices, wan_mac was set up with
mtd_get_mac_binary although the same address was set in DTS.
The wan_mac statement is removed in 02_network, no
lan_mac is present:
- buffalo,whr-g300n
- glinet,gl-mt300n-v2
- zyxel,keenetic-start
3. For the following device, lan_mac and wan_mac were set up
with mtd_get_mac_binary to the same address as set in DTS.
Both statements are removed in 02_network:
- buffalo,whr-600d
4. For some devices, it was possible to move setup from 02_network
to DTS by introducing previously missing mtd_mac_address:
- buffalo,whr-1166d
- buffalo,whr-300hp2
- buffalo,wsr-600dhp
- ohyeah,oy-0001
- planex,vr500
5. For one device, mtd_mac_address was just wrong and overwritten
by 02_network. Put the correct value in DTS and remove redundant
statement in 02_network:
- asus,rt-ac57u
6. For one device, MAC address defined in DTS is exchanged together
with lan_mac/wan_mac setup in 02_network, so that cases in
02_network can be merged:
- phicomm,k2p
For some devices, an empty case has to be used to prevent them
from falling into the default case and have
WAN address = eth0 address + 1 set to them.

Unfortunately, I can't find an easy way to recover the RE

TFTP upload will only work if selected from u-boot, which
means you have to open the device and attach to the serial
console. The TFTP update procedure does *not* accept the
published vendor firmware binaries. However, it allows to
flash kernel + rootfs binaries, and this works if you have
a backup of the original contents of the flash. It's probably
