f27336e115 ramips: mtk-mmc: don't advertise highmem support.
of_dma_configure() sets a default ->dma_mask of
DMA_BIT_MASK(32), claiming devices can DMA from
the full 32bit address space.
The mtk-mmc driver does not support access to
highmem pages, so it is really limited to the
bottom 512M (actually 448M due to 64M of IO space).
Setting ->dma_mask to NULL causes mmc_setup_queue()
to fall-back to using BLK_BOUNCE_HIGH to tell the
block layer to use a bounce-buffer for any highmem
pages requiring IO.

ar71xx: add model detection for UBNT AC-Mesh
This commit adds correct model detection for UniFi
AC-Mesh. Previously said device was incorrectly detected
as UniFi AC-Lite.

The Information about the device is stored at 0xC in the EEPROM
partition. It corresponds to the sysid in /etc/board.info of the
Ubiquiti stock firmware.

ar71xx: Add support for D-Link DAP-1330 a1
D-Link DAP-1330 rev. A1 is a wall-plug N300 Wi-Fi range extender,
based on Qualcomm/Atheros QCA9533 v2.

Short specification:

- 650/393/216 MHz (CPU/DDR/AHB)
- 1x 10/100 Mbps Ethernet
- 64 MB of RAM (DDR1)
- 8 MB of FLASH
- 2T2R 2.4 GHz
- 2x external antennas
- 6x LED (2 are bi-color), 2x button
- 4 pin on pcb (looking from eth port and from left to right tx,rx,gnd,vcc)

Flash instruction: use "factory" image directly in vendor GUI.

This device has a recovery system that assign the ip addr of env
variable "serverip" via dhcp to a pc, and the "ipaddr" value to itself.
The recovery it's triggered by a not bootable firmware,
or pressing the reset button during the bootloader startup (first 30 seconds).
The recovery uses a http page to restore the firmware, and it's checking
the firmware image header, so use the "factory" image to
restore or the original firmware.

You can access vendor firmware over serial using:
- login: root
- password: linuxrocks

Image was tested only in EU version of the device, but should work
also with the same device version sold in other countries.

8db84cc0ee ramips: add support for DLINK DWR-921-C3
The DWR-921-C3 Wireless Routers with LTE embedded modem is based on the
MT7620N SoC.

Specification:

  * MediaTek MT7620N (580 Mhz)
  * 64 MB of RAM
  * 16 MB of FLASH
  * 802.11bgn radio
  * 5x 10/100 Mbps Ethernet (1 WAN and 4 LAN)
  * 2x external, detachable (LTE) antennas
  * UART header on PCB (57600 8n1)
  * 6x LED (GPIO-controlled)
  * 1x bi-color Signal Strength LED (GPIO-controlled)
  * 2x button
  * JBOOT bootloader

Installation:
Apply factory image via d-link http web-gui.

How to revert to OEM firmware:
1.) Push the reset button and turn on the power. Wait until LED start
    blinking (~10sec.)
2.) Upload original factory image via JBOOT http (IP: 192.168.123.254)
3.) If http doesn't work, it can be done with curl command:
    curl -F FN=@XXXXX.bin http://192.168.123.254/upg
    where XXXXX.bin is name of firmware file.

ace1686200 ramips: mt7620: eMMC: stop invalid memory access if only one device is defined
pdev->id is -1 when only one device exists, and is used:
* as an index into drv_mode[] to determine whether to use
  PIO or DMA mode (via host->id)
* as an index into msdc_6575_host[], to store the
  mmc_priv() data.

Obviously, -1 is not a valid index in either case, causing
us to read invalid memory, and memory corruption,
respectively.

The invalid memory read is causing non-deterministic
behaviour, in particular in the v4.4 kernel it still
picked DMA mode, but in the v4.9 it now always picks
PIO mode.
Also, PIO mode doesn't work, causing the following:

/ # echo 3 > /proc/sys/vm/drop_caches
[ 3845.249237] sh (128): drop_caches: 3

/ # /root/usr/lib/libc.so
[ 3846.096070] do_page_fault(): sending SIGSEGV to libc.so for invalid read access from 7f9cb5a0
[ 3846.104758] epc = 779b0ea4 in libc.so[7792f000+c3000]
[ 3846.109907] ra  = 779a8004 in libc.so[7792f000+c3000]
Segmentation fault

/ # /root/usr/lib/libc.so
musl libc (mipsel-sf)
Version 1.1.16-git-40-g54807d47
Dynamic Program Loader
Usage: /root/usr/lib/libc.so [options] [--] pathname [args]

(i.e. initial page-in of any binary causes a segfault,
subsequent access works.)

While this change doesn't fix PIO mode, it at least makes
us deterministically use DMA (which works), and it also
stops us from corrupting memory.

c555b524c7 apm821xx: increase WNDR4700's dtb+kernel partition to 3.5 MiB
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!).

This new initramfs can be loaded through the MR24 U-boot
in the following way:

=> setenv ipaddr 192.168.1.1
=> setenv bootargs console=ttyS0,$baudrate
=> tftpboot c00000 192.168.1.2:meraki_mr24-initramfs-kernel.bin

e3bf92edf5 ramips: fix switch and MAC address for WHR-G300N
WHR-G300N has 5 ethernet ports (lan: 4, wan: 1), but there was no
correct configuration in 02_network script and 6 ports was configured
on the switch.
Also, since the MAC address was not acquired from factory partition,
incorrect values was set to LAN and WAN interfaces.

This commit fixes these issues.

7004f681cd ipq40xx: Add reserved memory for WPJ428
The APPSBL and anything after that it not allowed to touch some of the
memory regions which are used by other components. Still trying to write to
the memory can lead to sudden device restarts

The device manufacturer only provided a very rough list of regions:

* rsvd1:     0x87000000 0x500000
* wifi_dump: 0x87500000 0x600000
* rsvd2:     0x87b00000 0x500000

A more detailed list for devices using the AP.DK reference design memory
maps was provided by Roman Yeryomin <roman@advem.lv> in commit 56f2df879fd
("ipq806x: ipq4019: add ap-dk01.1-c1 board support"):

* apps_bl:          0x87000000 0x400000
* sbl:              0x87400000 0x100000
* cnss_debug:       0x87500000 0x600000
* cpu_context_dump: 0x87b00000 0x080000

* tz:               0x87e80000 0x180000

The u-boot function ipq_fdt_mem_rsvd_fixup seems to suggest that only the
rsvd2 (tz_apps, smem, tz) should be protected. All other regions would have
been removed by it when CONFIG_QCA_APPSBL_DLOAD is not enabled. This allows
to reduce the 16MB reserved memory region to only 4.5MB.
