* ath79: further fixes for ZyXEL NBG6716Adrian Schmutzler2020-04-141-7/+10
| | | | | | | | | | | | | | | | | | This applies further fixes to the DTS of ZyXEL NBG6716 based on what is found in ar71xx (mach-nbg6716.c): - use WiFi label names as in ar71xx - fix WPS gpio number - fix GPIO_ACTIVE_HIGH and mode for WiFi switch - add codes for USB eject buttons - fix node name for "internet" LED This device has separate LEDs for WAN and "Internet". As the WAN-LED (and the four LAN-LEDs) are driven independent of the setup in DT/01_leds, the "internet" LED is left unassigned (in contrast to ar71xx, where it was set up effectively as a second WAN LED) Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* ramips: define image recipe for uncompressed uimage with loaderChuanhong Guo2020-04-141-0/+5
| | | | | | | | | Some devices have bootloaders with broken lzma code resulting in failed decompression or corrupted kernel code. This image recipe allows to sacrifice 5KB for OpenWrt LZMA loader and take over the task of decompress kernel. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>

* ath79: add read support using spi-memLuiz Angelo Daros de Luca2020-04-142-0/+140
| | | | | | | | | | | | | | | | Reimplements read optimization on top of spi-mem. Similar to what 461-spi-ath79-add-fast-flash-read.patch used to do with the dropped flash read interface. It accelerate only fast-read op reading flash directly from memory mapped region. 'm25p,fast-read' must be set in order to use the new spi-mem. It improved read speed up to 3x on old devices (tplink,tl-wr2543-v1) while no speed improvement was noticed on newer devices like (tplink,archer-c7-v2).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Buffalo LinkStation LS421DE is a dual bay NAS, based on Marvell Armada 370 Hardware: SoC: Marvell Armada 88F6707-A1 CPU: Cortex-A9 1200 MHz, 1 core Flash: SPI-NOR 1 MiB, NAND 512 MiB RAM: DDR3 512 MiB Ethernet: 1x 10/100/1000 Mbps USB: 1x 2.0, 1x 3.0 SATA: 2x 3.0 Gbps LEDs/Input : 5x / 2x (1x button, 1x slide-switch) RTC: Ricoh RS5C372A, I2C, no battery Flash instruction (UART+TFTP): 1. Downgrade the OEM firmware to 1.34 version (BUFFALO_BOOTVER=0.13) 2. Remove any hard drive from inside the bays. 3. Boot the Openwrt initramfs image using the U-Boot serial console: tftpboot 0x1200000 buffalo_ls421de-initramfs-kernel.bin bootm 0x1200000 4. Flash the sysupgrade image using the Openwrt console: sysupgrade -n buffalo_ls421de-squashfs-sysupgrade.bin 5. Wait until it finish, the device will reboot with Openwrt installed on the NAND flash. Note: - Device shuting down doesn't work, even if the power slide switch is used. We must first, via MDIO, set the unused LED2 at the ethernet phy0 to off state. Reboot works ok.

| | | | | | | | | | | | This hack is needed for old ethernet driver: On mt7620, we have two exposed RGMII ports that connects to builtin switch. However, swconfig has no way to interact with phy subsystem. As a result, we have to register both PHYs to ethernet mac instead and this patch prevents main ethernet interface from going down due to phy link changes.

| | | | | | | | | | | | | | | The "proper" vendor prefix for Ubiquiti is "ubnt", this is used in all targets except ramips and also recommended by the kernel. This patch adjusts the various board/image/device name variables accordingly. Since we touch it anyway, this also adds the space in "EdgeRouter X" as a hyphen to those variables to really make them consistent with the model name.

Thus, narrower frequency limits compared to other devices are required for limiting wi-fi frequency correctly. Without this, non-supported frequencies are activated. Flash instructions ================== 1. Open the router management page (192.168.0.1). 2. Update router firmware using "initramfs-kernel.bin". 3. After updating, run sysupgrade with "sysupgrade.bin". Recovery instructions ===================== WN-AX2033GR contains Zyxel Z-LOADER 1. Setup TFTP server (IP address: 10.10.10.3). 2. Put official firmware into TFTP server directory (distribution site: https://www.iodata.jp/lib/software/w/2068.htm) 3. Connect WX-AX2033GR Ethernet port and computer that runs TFTP server. 4. Connect to serial console. 5. Interrupt booting by Esc key. 6. Flash firmware using "ATNR 1,[firmware filename]" command.
