aa82fdf110 ramips: fix GB-PC1/PC2 build error
With ed25e3ac02 ("ramips: fix some clocks in mt7621.dtsi") the
cpuclock node was dropped from the mt7621.dtsi without removing the
references to this node from the GB-PC1/PC2 dts files.

Remove them now, to fix the build error.

e4d9217fe5 ramips: improve BDCOM WAP2100-SK support
Use the generic board detection instead of the target specific one as
all recent additions are doing.

Setup the USB led via devicetree (a58535771f) and include the required
driver by default. Merge the led userspace setting with an existing
identical case.

Use the wps led for boot status indication.

Move the partitions into a partition table node (6031ab345d) and drop
needless labels. Drop misplaced cells properties (53624c1702).

Cleanup the pinmux and only switch pins to gpio functions which a
referenced as gpio in the dts.

Match the maximum image size with the size of the firmware partition.

71ba834cf1 ramips: add Sanlinking Technologies D240 pinmux quirk
The sd function of the nd_sd group configures two of the groups pins as
gpios. The pins are used as PCIe reset/power.

Due to the driver load order, the pins are configured way to late if
triggered by the sd-card driver.

To not introduce another kind of driver load order dependency and
configure the pins as early as possible, means during pinmux driver
load.

- Flash: 16 MB
- Ethernet: 5 FE ports
- Wireless radio: 2T2R 2.4 GHz and 1T1R 5 GHz (MT7610EN, unsupported)

- Other: USB port, SD card slot and 2x external antennas (non-detachable)

Flashing instructions:

A) The U-Boot has HTTP based firmware upgrade

  A1) Flashing notes

  We've identified so far two different batches of units, unfortunately
  each batch has different U-Boot bootloader flashed with different
  default environment variables, thus each batch has different IP address
  for accessing web based firmware updater.

  * First batch has web based bootloader IP address 1.1.1.1
  * Second batch has web based bootloader IP address 192.168.1.250

  In case you can't connect to either of those IPs, you can try to get
  the default IP address via two methods:

  A1.1) Serial console, then the IP address is visible during the boot

   ...
   HTTP server is starting at IP: 1.1.1.1
   raspi_read: from:40004 len:6
   HTTP server is ready!
   ...

  A1.2) Over telnet/SSH using this command:

   root@bdcom:/# grep ipaddr= /dev/mtd0
   ipaddr=1.1.1.1

  A2) Flashing with browser

  * Change IP address of PC to 1.1.1.2 with 255.255.255.0 netmask
  * Reboot the device and try to reach web based bootloader in the
    browser with the following URL http://1.1.1.1

  * Quickly select the firmware sysupgrade file and click on the
    `Update firmware` button, this all has to be done within 10 seconds,
    bootloader doesn't wait any longer

   If done correctly, the web page should show UPDATE IN PROGRESS page
   with progress indicator. Once the flashing completes (it takes roughly
   around 1 minute), the device will reboot to the OpenWrt firmware

  A3) Flashing with curl

   sudo ip addr add 1.1.1.2/24 dev eth0
   curl \
      --verbose \
      --retry 3 \
      --retry-delay 1 \
      --retry-max-time 30 \
      --connect-timeout 30 \
      --form "firmware=@openwrt-ramips-mt7620-BDCOM-WAP2100-SK-squashfs-sysupgrade.bin" \
      http://1.1.1.1

   Now power on the router.

B) The U-boot is based on Ralink SDK so we can flash the firmware using UART.

   1. Configure PC with a static IP address and setup an TFTP server.
   2. Put the firmware into the tftp directory.
   3. Connect the UART line as described on the PCB (G=GND, R=RX, T=TX)
   4. Power up the device and press 2, follow the instruction to set device and
      tftp server IP address and input the firmware file name. U-boot will then load
      the firmware and write it into the flash.

as indicated in commit c5bf408ed6 "(ramips: fix image generation for mt76x8")
more rework was needed to fix the other issues.

Building on another machine, but using the same arch, showed
the application failing again for different reasons.

Fix this by completely rewriting the application, fixing following found issues:

- buffer overflows, resulting in stack corruption
- flaws in memory requirement calculations (too small, too large)
- memory leaks
- missing bounds checking on string handling
- non-reproducable images, by using unitilized memory in checksum calculation
- missing error handling, resulting in succes on specific image errors
- endianness errors when building on BE machines
- various minor build warnings
- documentation did not match the code actions (header item locations)
- allowing input to be decimal, hex or octal now

dependencies selected by the package.

Explicitly exclude all 3 mt76 packages, plus the metapackage.
Otherwise, these modules will be included in the build, wasting
a few hundred kilobytes.

0cda4af005 kernel: bump 4.14 to 4.14.70
Refreshed all patches.

Added new patch:
- 192-Revert-ubifs-xattr-Don-t-operate-on-deleted-inodes.patch

This fixes a bug introduced in upstream 4.14.68 which caused targets using
ubifs to produce file-system errors on boot, rendering them useless.

Compile-tested on: cns3xxx, imx6, x86_64
Runtime-tested on: cns3xxx, imx6, x86_64

93bfafb8dc ramips: Fix early memory calculation for certain MIPS platforms
Kernel upstream commit 67a3ba25aa95 ("MIPS: Fix incorrect mem=X@Y handling") introduced a new issue for rt288x where "PHYS_OFFSET" is 0x0 but the calculated "ramstart" is not. As the prerequisite of custom memory map has been removed, this results in the full memory range of 0x0 - 0x8000000 to be marked as reserved
for this platform.

This patch adds the originally intended prerequisite again.

6bbb220255 ramips: add support for TP-Link TL-MR3020 v3
TP-Link TL-MR3020 v3 is a pocket-size router based on MediaTek MT7628N.

This PR is based on the work of @meyergru[1], with his permission.

Specification:
- MediaTek MT7628N/N (575 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz
- 1x 10/100 Mbps Ethernet

Flash instruction:

The only way to flash the image in TL-MR3020 v3 is to use
tftp recovery mode in U-Boot:

1. Configure PC with static IP 192.168.0.225/24 and tftp server.
2. Rename "openwrt-ramips-mt76x8-tplink_tl-mr3020-v3-squashfs-tftp-recovery.bin"
   to "tp_recovery.bin" and place it in tftp server directory.
3. Connect PC with the LAN port, press the reset button, power up
   the router and keep button pressed for around 6-7 seconds, until
   device starts downloading the file.
4. Router will download file from server, write it to flash and reboot.

287b7aa583 ramips: drop obsolete sd card driver code
The pinmux for all SoCs using this driver is now set via the pinmux. It
makes this code obsolete.

Some of the code targeting the mt76x8 SoCs is still required. The sd
card pins share the pads with the EPHY. These pads need to be switched
to digital mode if the pins are used for sd cards.

The eMMC 8-bit mode has to be enabled via pinmux instead of a kernel
option. The uart2 group need to be set to function "sdxc d5 d4", pwm1
to "sdxc d6" and pwm0 to "sdxc d7" to do so. It can't be done by as
part of a default pinmux, as it would break the normal operation of
uart2.

a14097e8e0 ramips: fix mt7620a ND/SD pins pinmuxes
Drop the nd_sd gpio pinmux in case sdcard is used. They're mutually
exclusive and for most of the boards not even used as GPIOs.

If the pins are in sdcard mode, the pins ND_WE_N and ND_CS_N are still
GPIOs (#45 and #46).

1d08951628 ramips: add rt3352 SPI_CS1 pinmux
The rt3352 has a pin that can be used as second spi chip select,
watchdog reset or GPIO. The pinmux setup was missing the definition of
said pin but it is already used in the SoC dtsi.
