* mpc85xx: add SPI kernel loader for TP-Link TL-WDR4900 v1Matthias Schiffer2022-10-1422-0/+1364
| | | | | | | | | | | Similar to the lzma-loader on our MIPS targets, the spi-loader acts as a second-stage loader that will then load and start the actual kernel. As the TL-WDR4900 uses SPI-NOR and the P1010 family does not have support for memory mapping of this type of flash, this loader needs to contain a basic driver for the FSL ESPI controller.

Installation Web-UI ------------------- Upload the Factory image using the devices Web-Interface. As the device uses a dual-image partition layout, OpenWrt can only installed on Slot A. This requires the current active image prior flashing the device to be on Slot B. If the currently installed image is started from Slot A, the device will flash OpenWrt to Slot B. OpenWrt will panic upon first boot in this case and the device will return to the ZyXEL firmware upon next boot. If this happens, first install a ZyXEL firmware upgrade of any version and install OpenWrt after that. Installation TFTP ----------------- This installation routine is especially useful in case * unknown device password (NWA55AXE lacks reset button) * bricked device Attach to the UART console header of the device. Interrupt the boot procedure by pressing Enter. The bootloader has a reduced command-set available from CLI, but more commands can be executed by abusing the atns command. Boot a OpenWrt initramfs image available on a TFTP server at 192.168.1.66. Rename the image to owrt.bin $ atnf owrt.bin $ atna 192.168.1.88 $ atns "192.168.1.66; tftpboot; bootm" Upon booting, set the booted image to the correct slot: $ zyxel-bootconfig /dev/mtd10 get-status $ zyxel-bootconfig /dev/mtd10 set-image-status 0 valid $ zyxel-bootconfig /dev/mtd10 set-active-image 0 Copy the OpenWrt ramboot-factory image to the device using scp.

* ramips: move mt7621_nand driver to filesStijn Tintel2022-10-102-1356/+1353
| | | | | | | | | | | | The patch was rejected by upstream. The mtk_nand driver should be modified to support the mt7621 flash controller instead. As there is no newer version to backport, or no upstream version to fix bugs, let's move the driver to the files dir under the ramips target. This makes it easier to make changes to the driver while waiting for mt7621 support to land in mtk_nand.

* ath79: add low_mem to tiny imageNick Hainke2022-10-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Devices with SMALL_FLASH enabled have "SQUASHFS_BLOCK_SIZE=1024" in their config. This significantly increases the cache memory required by squashfs [0]. This commit enables low_mem leading to a much better performance because the SQUASHFS_BLOCK_SIZE is reduced to 256. Example Nanostation M5 (XM): The image size increases by 128 KiB.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Serge Vasilugin reports: To improve mt7620 built-in wifi performance some changes: 1. Correct BW20/BW40 switching (see comments with mark (1)) 2. Correct TX_SW_CFG1 MAC reg from v3 of vendor driver see https://gitlab.com/dm38/padavan-ng/-/blob/master/trunk/proprietary/rt_wifi/rtpci/3.0.X.X/mt76x2/chips/rt6352.c#L531 3. Set bbp66 for all chains. 4. US_CYC_CNT init based on Programming guide, default value was 33 (pci), set chipset bus clock with fallback to cpu clock/3. 5. Don't overwrite default values for mt7620. 6. Correct some typos. 7. Add support for external LNA: a) RF and BBP regs never be corrected for this mode b) eLNA is driven the same way as ePA with mt7620's pin PA but vendor driver explicitly pin PA to gpio mode (for forrect calibration?) so I'm not sure that request for pa_pin in dts-file will be enough First 5 changes (really 2) improve performance for boards w/o eLNA/ePA. Changes 7 add support for eLNA Configuration w/o eLAN/ePA and with eLNA show results tx/rx (from router point of view) for each stream: 35-40/30-35 Mbps for HT20 65-70/60-65 Mbps for HT40 Yes. Max results for 2T2R client is 140-145/135-140 with peaks 160/150, It correspond to mediatek driver results. Boards with ePA untested.

Connect to the booted device at 192.168.1.20 using username/password "ubnt". 2. Update the bootloader environment. $ fw_setenv devmode TRUE $ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr); fdt rm /signature; bootubnt" $ fw_setenv bootcmd "run boot_openwrt" 3. Transfer the OpenWrt sysupgrade image to the device using SCP. 4. Check the mtd partition number for bs / kernel0 / kernel1 $ cat /proc/mtd 5. Set the bootselect flag to boot from kernel0 $ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4 6. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1 $ dd if=openwrt.bin of=/dev/mtdblock6 $ dd if=openwrt.bin of=/dev/mtdblock7 7. Reboot the device. It should boot into OpenWrt.

| | | | | | | | | | The patch adding support for LEDs connected to a reset controller did not apply any more, refresh it on top of current master. Fixes: 53fc987b2552 ("generic: move ledbar driver from mediatek target") Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: Daniel Golle <daniel@makrotopia.org> (cherry picked from commit 76fc277917fc847892dbbf525aea9f90a035d296)
* generic: move ledbar driver from mediatek targetSven Wegener2022-09-183-3/+4
| | | | | | | This moves the ledbar driver to generic, to be also used by the ramips target. Signed-off-by: Sven Wegener <sven.wegener@stealer.net> (cherry picked from commit 53fc987b25524c28525313347f0e2e5653dce43c)
* mediatek: add led countSven Wegener2022-09-181-1/+7
| | | | | | | | | | The LEDs connected to the MCU are so-called smart LEDs and their signal is daisy-chained. Because of this, the MCU needs to be told how many LEDs are connected. It also means the LEDs could be individually controlled, if the MCU has a command for this.

* mediatek: add initialization after resetSven Wegener2022-09-181-0/+14
| | | | | | | | | During GPIO initialization the pin state flips and triggers a reset of the ledbar MCU. It needs to be moved through an initialization sequence before working correctly. Signed-off-by: Sven Wegener <sven.wegener@stealer.net> (cherry picked from commit 013a956f086dc5d88f6e9cbd852ed4d900d436e0)
* mediatek: add support for reset gpioSven Wegener2022-09-181-0/+26
| | | | | | | | Some versions of the ledbar MCU have a reset pin. It needs to be correctly initialized or we might keep the MCU in reset state. Signed-off-by: Sven Wegener <sven.wegener@stealer.net> (cherry picked from commit 84e4bbf5f049cdb862eb25c446bd6973ed4238aa)
* mediatek: support reading more than one byte of responseSven Wegener2022-09-181-7/+8
| | | | | | | There are commands that return more than one byte of response. Signed-off-by: Sven Wegener <sven.wegener@stealer.net> (cherry picked from commit 7c852e7df50e370b26b060c96c3cc4491cee88eb)
* mediatek: cast literal value to charSven Wegener2022-09-181-1/+1
| | | | | | | | | | | Or the comparison against a signed char is always true, because the literal 0xaa is treated as an unsigned int, to which the signed char is casted during comparison. 0xaa is above the positive values of a signed char and negative signed char values result in values larger than 0xaa when casted to unsigned int.

* mediatek: correctly log i2c responseSven Wegener2022-09-181-2/+2
| | | | | | | | The read response is in the i2c_response variable. Also use %hhx format, because we're dealing with a single char. Signed-off-by: Sven Wegener <sven.wegener@stealer.net> (cherry picked from commit c4f9f9b44c82ffeacd9d3c00ba07171c35831337)
