DEVICE_TYPE is a target/subtarget variable, and it does not have
any effect when set in a device definition. It can only be set
in a target's or subtarget's Makefile.
Consequently, having it set anyway is misleading, so this drops
all cases.
This effectively reverts the following commits:

This patch prepares the WNDR4700 to use the HDD sensor for
the thermal zone. While the kernel's thermal.txt device-tree
binding documentation files talks about supporting multiple
sensors for a zone. This sadly is NOT the case. Even the most
current upstream kernels (5.6-rc) supports just >one< sensor
per zone: (driver/base/of-thermal.c:886)
| * REVIST: for now, the thermal framework supports only
| * one sensor per thermal zone. Thus, we are considering
| * only the first two values as slope and offset.
I do hope that this warning will prevent others wasteing time
on trying to figure out why their multi-sensor thermal-zones
definitions are not working as specified.

The allocation of LEBs to ubi volumes is handled by the sysupgrade script:
package/base-files/files/lib/upgrade/nand.sh
and the ubimkvol and or ubirsvol command. Therefore, padding of the
kernel blob is not needed at all, so use cat instead of dd. The
BLOCKSIZE variable was only used in the dd command. In any case, 63k
made no sense for the way BLOCKSIZE was being used.
63k (64512) does make sense for DTB_SIZE because of the offsets expected
by u-boot given extant u-boot-env variables.

In the past, the MX60(W)'s recovery images always had problems
with the size restriction and never really worked without manual
intervention. But starting with 4.19, the MX60(W)'s kernel image
outgrew the allocated space for sysupgrade images as well. Hence
This patch reworks the initramfs, which allows the device to ease
up on the impossible tight kernel size requirements for the
sysupgrade creation and packaging. And as a result, the now
orphaned special ramdisk setup is removed in the process.
This new initramfs can be loaded through the MX60(W) U-boot

Flashing requirements:
- needs a tftp server at 192.168.1.10/serverip.
- special 8P8C(aka RJ45)<->D-SUB9 Console Cable
("Cisco Console Cable"). Note: Both WNDAP6x0 have
a MAX3232 transceivers, hence no need for any separate
CMOS/TTL level shifters.
External Antenna:
The antennae mux is controlled by GPIO 11 and GPIO14. Valid Configurations:
= Config# = | = GPIO 11 = | = GPIO 14 = | ===== Description =====
1. | 1 / High | 0 / Low | Use the internal antennae (default)
2. | 0 / Low | 1 / High | Use the external antennae
The external antennaes are only meant for the 2.4 GHz band.
One-way Flashing instructions via u-boot:
0. connect the serial cable to the RJ45 Console Port
Note: This requires a poper RS232 and not a TTL/USB adaptor.
1. power up the AP and interrupt the u-boot process at
'Hit any key to stop autoboot'
2. setup serverip and ipaddr env settings
Enter the following commands into the u-boot shell
# setenv ipaddr 192.168.1.1
# setenv serverip 192.168.1.10
3. download the factory.img image to the AP
Enter the following commands into the u-boot shell
# tftp ${kernel_addr_r} openwrt-apm821xx-nand-netgear_wndap660-squashfs-factory.img
4. verfiy image integrity
Enter the following commands into the u-boot shell
# crc32 $fileaddr $filesize
If the calculated crc32 checksum does not match, go back to step 3.
5. flash the image
Enter the following commands into the u-boot shell
# nand erase 0x110000 0x1bd0000
# nand write ${kernel_addr_r} 0x110000 ${filesize}
6. setup uboot environment
Enter the following commands into the u-boot shell
# setenv bootargs
# setenv fileaddr
# setenv filesize
# setenv addroot 'setenv bootargs ${bootargs} root=/dev/ubiblock0_0'
# setenv owrt_boot 'nboot ${kernel_addr_r} nand0 0x110000; run addroot; run addtty; bootm ${kernel_addr_r}'

This remedies an issue with the MBL Duo if both disks are inserted
and contain OpenWrt. kernel and dtb would be loaded from SATA 1:1
while rootfs (/dev/sda2) would be mounted on SATA 0:1.
Such a mix&match would obviously only work if both OpenWrt versions/
builds are identical, and especially fail after sysupgrade upgraded
the system disk on SATA 0:1.
The fallback to SATA 1:1 needs to be kept for MBL Single (only has
SATA 1:1) and MBL Duo with one disk inserted on SATA 1:1. To speed
up booting in those cases, the unneccesarily doubled "sata init"
will only be called once. (In theory it could be omitted completely
since the on-flash boot script already initializes SATA to load the
on-disk boot script.)
Tested on MBL Duo (all possible combination of disks) and MBL Single

This patch adds support for squashfs as the root filesystem.
advantages:
- migrate from a existing -ext4 installation and back
with the sysupgrade utility
- existing partition layout will not be lost during switch
- slightly smaller image size as compared to the -ext4 image.
disadvantages:
- needs f2fs + tools. This is because fstools rootdisk.c decides based
on the partition size (currently root partitions > 100 MiB) f2fs is
used as the rootfs_data filesystem.
- rootfs_data is placed into the rootfs partition after the squashfs.
This makes it difficult for tools that expect a /dev/sda${X} device.
It also makes it difficult for data recovery tools as they might not
expect to find a embedded partition or will be slightly confused.
... or will not support f2fs.
For people with existing build configurations: make sure to include mkf2fs
and f2fsck packages into the image. Otherwise the new -squashfs image will
only boot from the ram-overlay.
Note:
All overlay data (configurations/all installed packages/...) will be
placed in inside the rootfs partition (i.e. /dev/sda2) just after the
squashfs image.

This patch cleans and reworks the WNDR4700 dts to increase the
now combined dtb+kernel partition to 3.5 MiB. This has become
necessary due to the switch to GCC 7.3 and the ever increasing
kernel binary size.
The dtb+kernel partition was combined in order to finally
fix the problem with out-of-sync device-trees. From now
on, the kernel and device-tree will always be updated together.
Upgrade Note:
Existing installations will have to use the TFTP firmware
recovery option in order to install the update. Affected users
are advised to make a backup of their existing configuration
prior to running sysupgrade:
<https://openwrt.org/docs/guide-user/installation/generic.backup#backup_openwrt_configuration>
Due to the repartitioning of the NAND, the generated backup
should be placed on either the internal HDD, an attached
USB-Stick or on another PC (externally).
To manually trigger the firmware recovery, the reset button has
to be pressed (and hold) during boot. U-boot will enter the "Upgrade
Mode" and starts a tftpserver listening on 192.168.1.1 for a
tftp client from one of the four LAN/Ethernet ports to connect and
upload the new system: (enable tftp binary mode!).

The patch "images: bump default rootfs size to 256 MB"
a1f83bad60 caused a crash
during boot for the recovery images. This is because
both variants of the MyBook Live only have 256MB of RAM
and for the recovery option, the ext4 rootfs was simply
stored in the RAMDISK.
This patch replaces recovery image for the MBL with an
initramfs kernel.
In order to boot the initramfs (for recovery or development):
0. copy the initramfs and device tree into tftp's server directory
# cp *-initramfs-kernel.bin to /tftp-server/mbl.bin
# cp *-ext4-kernel.dtb to /tftp-server/fdt.bin
1. Connect the MyBook Live (Duo) serial port.
(Warning! Use a 3.3v level shifter).
2. Hit Enter during u-boot and insert these three lines:
# setenv serverip 192.168.1.254; setenv ipaddr 192.168.1.1;
# tftp ${kernel_addr_r} mbl.bin; tftp ${fdt_addr_r} fdt.bin
# run addtty addmisc; bootm ${kernel_addr_r} - ${fdt_addr_r}
Where 192.168.1.254 is your TFTP server.
