It's reported that current memory detection code occasionally detects
larger memory under some bootloaders.
Current memory detection code tests whether address space wraps around
on KSEG0, which is unreliable because it's cached.
Rewrite memory size detection to perform the same test on KSEG1 instead.
While at it, this patch also does the following two things:
1. use a fixed pattern instead of a random function pointer as the magic
value.
2. add an additional memory write and a second comparison as part of the
test to prevent possible smaller memory detection result due to
leftover values in memory.

Flash accessing instruction templates are determined during probe since
v5.6 for spimem-dirmap support in spi-nor driver in upstream commit:
df5c21002cf4 ("mtd: spi-nor: use spi-mem dirmap API")
As a result, changing bus_width on the fly doesn't work anymore and this
patch will cause executing spi-mem ops with 3-byte address on 16-32M
flash area.
We can't easily revert that behavioral change upstream so drop the patch
to prevent u-boot and eeprom from being erased.

Hardware
--------
MediaTek MT7621 SoC
256M DDR3
16MB BoHong SPI-NOR
MediaTek MT7905+7975 2x2T2R DBDC bgnax / acax
RGB LED
WPS + RESET Button
UART on compute module (silkscreened / 115200n8)
The router itself is just a board with Power / USB / RJ-45 connectors
and DC/DC converters. The SoC and WiFi components are on a
daughterboard which connect using two M.2 connectors.
The compute module has the model number "T-CB1800K-DM2 V02" printed on
it. The main baord has "T-MB5EU V01" printed on it. This information
might be useful, as it's highly likely either of these two will be
reused in similar designs.
The router itself is sold as Tenbay T-MB5EU directly from the OEM as
well as "KuWFI AX1800 Smart WiFi 6 Eouter" on Amazon.de for ~50€ in a
slightly different case.
Installation
------------
A Tool for creating a factory image for the Vendor Web Interface can be
found here: https://github.com/blocktrron/t-mb5eu-v01-factory-creator/
As the OEM Firmware is just a modified LEDE 17.01, you can also access
failsafe mode via UART while the OS boots, by connecting to UART
and pressing "f" when prompted. The Router is reachable at
192.168.1.1 via root without password.
Transfer the OpenWrt sysupgrade image via scp and apply with sysupgrade
using the -n and -F flags.
Alternatively, the board can be flashed by attaching to the UART
console, interrupting the boot process by keeping "0" pressed while
attaching power.
Serve the OpenWrt initramfs using a TFTP server with address
192.168.1.66. Rename the initramfs to ax1800.bin.
Attach your TFTP server to one of the LAN ports. Execute the following
commands.
$ setenv ipaddr 192.168.1.67
$ setenv serverip 192.168.1.66
$ tftpboot 0x84000000 ax1800.bin
$ bootm
Wait for the device to boot. Then transfer the OpenWrt sysupgrade image
to the device using SCP and apply sysupgrade.

This adds a driver for the AW9523 I2C GPIO expander.
This driver is required to make LEDs as well as buttons on the Tenbay
T-MB5EU-V01 work.
This driver already had several upstream iterations. I'm working to
push this driver to mainline.

It was reported AR8033 did not work in fiber operation mode on the ER-X.
While the earlier attempt of fixing this mitigated the issue of 1000
Base-X link mode not being supported, it also switched to the copper
page, breaking fiber operation altogether.
Extend the hack adding fiber operation so it does not switch to the
copper page. Also remove the part where the supported link mode bit for
1000 Base-X is removed, as this is required for fiber operation.

ath79, lantiq, ipq40xx, ramips all use the OpenWrt-specific gpio-export
functionality. Consolidate the patch that adds it under hack-5.10 since
this logic is obviously not target-specific. For those who want to
disable it, unsetting CONFIG_GPIO_SYSFS symbol will disable this code.
