ramips: add support for ZBT WE1026-H This commit adds support for the ZBT WE1026-H, an outdoor AP with support for adding an internal LTE modem. The detailed specs are: * CPU: MT7620A * 2x 10/100Mbps Ethernet (LAN port has passive PoE support). * 16/32 MB Flash. * 128/256 MB RAM. * 1x USB 2.0 port. * 1x mini-PCIe slot (only USB2.0 bus). * 1x SIM slot (standard size). * 1x 2.4Ghz WIFI (rt2800). * 1x button. * 6x LEDS (4 GPIO-controlled). * 1x micro-SD reader. The following have been tested and working: - Ethernet switch - Wifi - Mini-PCIe slot + SIM slot - USB port - microSD slot - sysupgrade - reset button Installation and recovery: In order to install OpenWRT the first time or ito recover the router, you can use the web-based recovery system. Keep the reset button pressed during boot and access 192.168.1.1 in your browser when your machine obtains an IP address. Upload the firmware to start the recovery process. Notes: * When binding the USB LED to a usbport, the LED is switched on all the time due to the presence of an internal hub. Thus, it does not really signal any USB-information. * I only have the 32MB version and have only added support for this device. However, the files are structured so that adding support for the 16MB version should be easy. * Only the LAN port is accessible from the outside of the casing and LEDs are not visible.

ramips: fix reboot for remaining 32 MB boards The following devices have a Winbond W25Q256FV flash chip, which does not have the RESET pin enabled by default, and otherwise would require setting a bit in a status register. Before moving to Linux 5.4, we had the patch: 0053-mtd-spi-nor-add-w25q256-3b-mode-switch.patch which kept specific flash chips with explicit 3-byte and 4-byte address modes to stay in 3-byte address mode while idle (after an erase or write) by using a custom flag SPI_NOR_4B_READ_OP that was part of the patch. this was obsoleted by the patch: 481-mtd-spi-nor-rework-broken-flash-reset-support.patch which uses the newer upstream flag SNOR_F_BROKEN_RESET for devices with a flash chip that cannot be hardware reset with RESET pin and therefore must be left in 3-byte address mode when idle. The new patch requires that the DTS of affected devices have the property "broken-flash-reset", which was not yet added for most of them. This commit adds the property for remaining affected devices in ramips target, specifically because of the flash chip model. However, it is possible that there are other devices where the flash chip uses an explicit 4-byte address mode and the RESET pin is not connected to the SOC on the board, and those DTS would also need this property.
