ramips: add support for MTC Wireless Router WR1201
MTC Wireless Router WR1201 is the OEM name of the board. It is also sold rebranded as STRONG Dual Band Gigabit Router 1200. Specification: - SoC: MediaTek MT7621A (880 MHz) - Flash: 16 MiB - RAM: 128 MiB - Wireless: 2.4Ghz(MT7602EN) and 5Ghz (MT7612EN) - Ethernet speed: 10/100/1000 - Ethernet ports: 4+1 - 1x USB 3.0 - 1x microSD reader - Serial baud rate of Bootloader and factory firmware: 57600 The OEM webinterface writes only as much bytes as listed in the uImage header field to the flash. Also, the OEM webinterface evaluates the name field of uImage header before flashing (the string "WR1201_8_128") To flash via webinterface, is mandatory to use first initramfs.bin and after (from the OpenWrt) the sysupgrade.bin Some notes: - Some microSD will not work: mtk-sd 1e130000.sdhci: no support for card's volts mmc0: error -22 whilst initialising SDIO card mtk-sd 1e130000.sdhci: no support for card's volts mmc0: error -22 whilst initialising MMC card mtk-sd 1e130000.sdhci: no support for card's volts mmc0: error -22 whilst initialising SDIO card mtk-sd 1e130000.sdhci: card claims to support voltages below defined range mtk-sd 1e130000.sdhci: no support for card's volts mmc0: error -22 whilst initialising MMC card mtk-sd 1e130000.sdhci: no support for card's volts mmc0: error -22 whilst initialising SDIO card mtk-sd 1e130000.sdhci: no support for card's volts mmc0: error -22 whilst initialising MMC card Signed-off-by: Valentín Kivachuk <vk18496@gmail.com>v19.07.3_mercusys_ac12_duma
