From 98b86296e67dd2b467212fe1a577656e6d3725da Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Sat, 12 Oct 2019 00:49:15 +0200 Subject: ipq806x: add support for ASRock G10 The ASRock G10 is a 2.4/5 GHz band 11ac "Gaming" router, based on Qualcomm IPQ8064. Specifications: SoC: Qualcomm IPQ8064 CPU: Dual-Core A15 @ (384 - 1,400 MHz, 2C2T) DRAM: 512 MiB (~467 MiB available) NAND: 128 MB (Micron MT29F1G08ABBEAH4) WLAN0: 4T4R 5 GHz Wlan (QCA9980) WLAN1: 4T4R 2.4 GHz Wlan (QCA9980) ETH: 5x 10/100/1000 Mbps Ethernet (QCA8337) INPUT: Reset Button, WPS 2.4G and WPS 5G Button LEDS: 1 multicolor status LED USB: 2x USB 3.0 Type-A POWER: 12VDC/3A AC Adapter + dedicated Power Switch UART: Setting is 115200-8-N-1. 1x4 .1" unpopulated header on the PCB (J6 - very tiny silkscreen next to TX). Pinout: 1. 3v3 (Square - best skipped!), 2. RX, 3. GND, 4. TX WARNING: The serial port needs a TTL/RS-232 3.3v level converter! (Depending on the serial adapter RX and TX might need to be swapped). Note about the IR-Remote: There's a 8-Bit MCU (SONIX SN8F25E21SG) which is controlling the IR-Remote and is fed by the IR-Photodiode. The SoC can talk to the device via I2C. The vendor's GPL archive comes with the source of the interface driver for this as a (character driver), the main control software is however a blob. Installation Instructions: 1. Download factory image to disk 2. Apply factory image via stock web-gui Back to stock: 1. Login to router via ssh 2. run "asrock_g10_back_to_factory" script from /sbin Notes: - If something goes wrong durring sysupgrade, router will go back to factory image. - Asrock G10 uses partition layout from smem. So partition layout can be normal or alternate. - 900-arm-add-cmdline-override.patch was copied from 102-powerpc-add-cmdline-override.patch from powerpc target. Knowledge about BOOTCONFIG partition was based on user "jmomo" post from old OpenWrt forum (Post #50): https://forum.archive.openwrt.org/viewtopic.php?id=65956&p=2 Signed-off-by: Christian Lamparter [bump to 5.4, add factory image, fix sysupgrade, convert partition layout to smem, remove ipq-wifi-asrock-g10 and use ART, minor fixes] Co-Authored-by: Pawel Dembicki Signed-off-by: Pawel Dembicki Tested-by: Lukasz Ostapiuk --- .../patches-5.4/900-arm-add-cmdline-override.patch | 37 ++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 target/linux/ipq806x/patches-5.4/900-arm-add-cmdline-override.patch (limited to 'target/linux/ipq806x/patches-5.4/900-arm-add-cmdline-override.patch') diff --git a/target/linux/ipq806x/patches-5.4/900-arm-add-cmdline-override.patch b/target/linux/ipq806x/patches-5.4/900-arm-add-cmdline-override.patch new file mode 100644 index 0000000000..bb3aa2622c --- /dev/null +++ b/target/linux/ipq806x/patches-5.4/900-arm-add-cmdline-override.patch @@ -0,0 +1,37 @@ +--- a/arch/arm/Kconfig ++++ b/arch/arm/Kconfig +@@ -1836,6 +1836,14 @@ config ARM_ATAG_DTB_COMPAT_CMDLINE_MANGL + Only command line ATAG will be processed, the rest of the ATAGs + sent by bootloader will be ignored. + ++config CMDLINE_OVERRIDE ++ bool "Use alternative cmdline from device tree" ++ help ++ Some bootloaders may have uneditable bootargs.
