The DASAN H660GM-A GPON ONT exists in two hardware variants, one
distributed by ISPs and one sold directly by the manufacturer [1].
Split the single DTS into a shared dtsi and per-variant DTS files
with the correct GPIO mappings, flash layout, and LED definitions.

Add PCIe controller and PHY support for EN7528 SoC. This includes
a new PCIe PHY driver, EN7528-specific startup in the MediaTek PCIe
controller, and a fix for bogus prefetch window reads on bridges
that do not implement the registers.
Enable WiFi for the DASAN H660GM-A board with MT7603 (2.4 GHz) and
MT7615/MT7663 (5 GHz).

The EN7528 SoC uses a little endian MIPS architecture, unlike the big
endian EN751221 family. The tclinux TRX firmware format stores multi-byte
fields in the CPU's native byte order, requiring different header layouts
for each architecture:
- Big endian (EN751221): magic "2RDH", fields in big endian order
- Little endian (EN7528): magic "HDR2", fields in little endian order
Update tclinux-trx.sh to support both endianness variants:
- Add --endian parameter to select byte order (default: be)
- Add --model parameter for optional platform identifier field
- Convert to named parameters for clarity and extensibility
- Use hex32() helper for endian-aware 32-bit field output
Move TRX_ENDIAN configuration to subtarget files, allowing each subtarget
to specify its native byte order:
- en751221.mk: TRX_ENDIAN := be
- en7528.mk: TRX_ENDIAN := le

The EN7528 is a little endian dual-core MIPS 1004Kc SoC used in xPON
devices. Unlike the big endian EN751221, EN7528 uses the MIPS GIC
interrupt controller for SMP.
This adds minimal boot support for EN7528:
- New en7528 subtarget with mipsel architecture
- Kernel patches for EN7528 SoC with GIC support
- Timer driver extended to support GIC shared interrupts per CPU
- SPI driver fix for EN7528 chip select handling
- Generic device tree for initial bring-up

This device has one USB2.0 port, plus ethernet, 2x wifi, ethernet, xPON
and VoIP.
Installation instructions: (Assuming root shell via SSH or serial)
1. Place OpenWrt TRX file on a USB stick formatted VFAT
2. Plug in the stick to the modem
3. Type: mtd write -f -e tclinux /mnt/usb2_sda1/<name of file>.trx tclinux
At this point, both OpenWrt and the vendor OS will be installed
because the device has space for two operating systems. Switch the OS
to boot to OpenWrt:
1. mtd readflash tmpdata 999999999 0 reservearea
2. echo -n '0' | dd of=./tmpdata bs=1 count=1 seek=397311 conv=notrunc
3. mtd write -f -e reservearea ./tmpdata reservearea
4. reboot
WARNING: While you can install with SSH alone, you need serial to use
OpenWrt on EcoNet devices because the Ethernet driver has not yet been
developed.

The Nokia G-240G-E is an xPON device with an EN7526G, 256M of
memory and 128M of flash. It has 1 USB2 port as well as phone and
ethernet but no wifi. Flashing instructions are per the typical
process using xmodem in the bootloader. This and other things
are described here: https://openwrt.org/inbox/toh/bt/g-240g-e_1
In addition, a generic image is offered, this image can be loaded
into memory from within the bootloader and launched directly. It
is recommended on the wiki of G-240G-E and other EcoNet devices
to be used for backing up the flash before flashing OpenWRT.

The EN751221 has an XHCI that is compatible with MT7621.
While there is setup logic in the vendor code for both
EN751221 and MT7621, but MT7621 does not use it in mainline
or OpenWRT, and it appears to work correctly with EN751221.
Include SCSI / Mass Storage because many EcoNet devices
contain a builtin USB SD-Card reader.

The TP-Link Archer VR1200v (v2) is a low end DSL modem based on the
EcoNet EN751221 processor platform.
While it does have an unlocked bootloader, the factory upgrade feature
requires a cryptographic signature so flashing from the web UI is not
feasible.
The Archer VR1200v (v2) uses a dual-image layout. I have chosen to reuse
this to support dual-boot between OpenWRT and the factory firmware.
Flashing instructions (from bootloader):
Build and then locate the squashfs-sysupgrade.bin image file
Get the length of that file in hex: printf '%X\n' "$(stat -c%s the-file-squashfs-sysupgrade.bin)"
Connect to device with xmodem capability, e.g. picocom --send-cmd lsx -vv -b 115200 /dev/ttyUSB0
Switch device on and press a key within 3 seconds, you should get to a `bldr>` prompt
Type: xmdm 80020000 <file length hex>
Quickly start xmodem and send the file, in picocom that is ctrl+a ctrl+s <paste-the-file-name> enter If the transfer fails to start, wait 30 seconds to a minute for the bootloader prompt to return and then try the command again.
Once the transfer has completed successfully, type the following flash 80000 80020000 <file length hex>
Type `re` or simply restart the device to boot into OpenWRT

The SmartFiber XP8421-B is a fiber modem which is available for $20 online
and has 512MB of memory, 256MB of SPI NAND flash and 2 USB 2.0 ports in
addition to ethernet, wifi and XPON.
Because EcoNet is not currently producing evaluation boards, the XP8421-B
stands in as a convenient, low cost, off-the-shelf, representitive example
of the capabilities of the EN751221 econet processor. This is also the
example board that is included in the upstream Linux patchset.
The XP8421-B, and apparently many other devices of this platform, use a
dual-image layout. I have chosen to reuse this to support dual-boot between
OpenWRT and the factory firmware. Certain design decisions were made with
the goal of not overwriting data that is used by the factory OS.
This commit also introduces a utility for switching between OS_A and OS_B
which are used for OpenWRT and Factory OS respectively.
Flashing instructions (from bootloader):
Build and then locate the squashfs-tclinux.trx image file
Get the length of that file in hex: printf '%X\n' "$(stat -c%s the-file-squashfs-tclinux.trx)"

Switch device on and press a key within 3 seconds
Enter bootloader username and password: telecomadmin nE7jA%5m
Type: xmdm 80020000 <file length hex>
Quickly start xmodem and send the file, in picocom that is ctrl+a ctrl+s <paste-the-file-name> enter If the transfer fails to start, wait 30 seconds to a

EcoNet EN75xx is a big endian MIPS platform used in XPON (fiber),
DSL, and SIM (3g/4g) applications. Complete GPL vender SDKs exist
for this platform, but are based on Linux 2.6.
The bulk of this submission has already been accepted upstream:
https://patchwork.kernel.org/project/linux-mips/list/?series=960479&state=*
This platform uses a bootloader that is derived from old TrendChip
code. This bootloader implements a frustratingly complex Bad Block
Table which is implemented here in en75_bmt.c
This BMT is not upstreamed because it depends on mtk_bmt framework
which likewise is not upstreamed.
This BMT system rewrites block indexes in flash and if the bootloader
considers it to be corrupted, it will attempt to automatically rebuild
on boot. So without implementing the algorithm, you can't safely use
the disk at all.
