b33959a668 econet: add EN751627 subtarget and Zyxel EX3301-T0 board
The EN751627 EcoNet subtarget consists of the EN7516 DSL SoC and the
(rare) EN7527 xPON SoC.

We currently support pci / wifi, usb and flash, but the EN751221 eth
driver is not portable to this family right now.

Zyxel EX3301-T0 is a wifi router based on the EN7516, it is a DSL SoC
but lacks the DSL port.

Installation instructions:
1. Serial access is required, stop the Zyxel bootloader.
2. Use ATENv3 https://github.com/cjdelisle/ATENv3 to unlock bootloader
3. "ATLD x" on the prompt to start a TFTP server
4. Connect ethernet cable from any lan (yellow) port on modem to a
device.
5. On your device, configure network to 192.168.1.2/30
6. On your device, send TRX file to 192.168.1.1 with name x, i.e.
tftp -p -l ./econet/tclinux -r x 192.168.1.1
7. On modem, you should see a line like this:
"Total 8022324 (0x7A6934) bytes received" note the hex value
8. "ATGU" to enter econet bootloader
9. "flash 80000 80020000 <the hex number without 0x>"
For example: flash 80000 80020000 7A6934
10. "reboot 1" -- start the system

If it boots back into the factory OS, you need to switch OS, from the
ZHAL prompt:

1. "ATCB" -- load data from flash
2. "ATCF 0" -- switch to OS 0
3. "ATBT 1" -- enable flash write
4. "ATSB" -- save data
5. "ATSR 1" -- reboot system

32df0bdf59 econet: en7528: add basic ethernet support
EN7528 shares the same clock/reset controller as EN7523. Enable
COMMON_CLK_EN7523 and RESET_CONTROLLER for ethernet hardware resets.
Update econet-eth driver and add it as default package.

fab098cb61 econet: add EN7528 subtarget support
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

c43925313e econet: Add basic USB support with Mass Storage
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.

73d0f92460 kernel: Add new platform EcoNet MIPS
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.
