* ipq40xx: split files in 6.1 and 6.6 dedicated directoryChristian Marangi2024-04-02
| | | | | | | | | | | Since with recent kernel version DTS moved to a dedicated directory, it's required to split files to per kernel version to follow kernel version directory structure. Also makes use of DEVICE_DTS_DIR to target the correct DTS directory based on the kernel version. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>

* ipq40xx: wpj428: panic on squashfs error to work around boot limboLeon M. Busch-George2023-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apparently, a few ipq40xx devices have sporadic problems when reading the flash over SPI. When that happens, the result of the faulty SPI read is cached and it isn't re-attempted. Depending on when it happens, the router either panics and reboots or is left in a partially broken state (an application wont start). The data on the flash is alright. This wasn't the case with Openwrt with Linux < 5.x but I wasn't able to work out which software change was responsible. Github user karlpip created a patch for testing that disabled the cache entirely and added logs. Typically, only one or two SPI operations fail at a time: [689200.631152] spi-nor spi0.0: SPI transfer failed: -110 [689200.631280] spi_master spi0: failed to transfer one message from queue [689200.635369] jffs2: Write of 68 bytes at 0x00ffccf4 failed. returned -110, retlen 0 [689200.642014] jffs2: Not marking the space at 0x00ffccf4 as dirty because the flash driver returned retlen zero Because reads aren't re-attempted, squashfs can't recover: [3171844.279235] SQUASHFS error: Failed to read block 0x2bb912: -5 [3171844.279284] SQUASHFS error: Unable to read fragment cache entry [2bb912] [3171844.283980] SQUASHFS error: Unable to read page, block 2bb912, size 14e6c [3171844.291650] SQUASHFS error: Unable to read fragment cache entry [2bb912] [3171844.297831] SQUASHFS error: Unable to read page, block 2bb912, size 14e6c I assume there to be some kind of underlying electrical problem because, in my experience, this happens a lot more when PoE is used. NoTengoBattery has made an in-depth investigation: https://forum.openwrt.org/t/patch-squashfs-data-probably-corrupt/70480 .. and created a patch that evicts the page cache and retries reading: https://github.com/NoTengoBattery/openwrt/blob/linksys-ea6350v3-mastertrack/target/linux/ipq40xx/patches-5.4/9996-fs_squashfs_improve_squashfs_error_resistance.patch The patch also works well with the WPJ428 but NoTengoBattery didn't try to upstream it ("This is not the solution that should be used"). In 2020, I tried and failed to create a working patch that prevents faulty pages to be cached in the first place. Because I needed a solution, I backported "squashfs: add option to panic on errors " (10dde05b89980ef) which has since become available in Openwrt. The 'error=panic' option has been tested on a fleet of multiple hundred WPJ428s over multiple years. Without this patch, devices regularly went into 'limbo' on reboot or update and required a manual reboot. Devices with this patch don't. I was initially concerned that the kernel panic would leave devices with a real corrupted data but I haven't seen a case of actual corruption since (outside of people turning off the power during upgrades). The WPJ428 is the only device I tested this patch on - others might also benefit. Reviewed-by: Robert Marko <robimarko@gmail.com> Signed-off-by: Leon M. Busch-George <leon@georgemail.eu>

* ipq40xx: utilize nvmem-cells for macs & (pre-)calibration dataChristian Lamparter2022-01-15
| | | | | | | | | | | | | | | moves extraction entries out of 11-ath10k-caldata and into the individual board's device-tree. Some notes: - mmc could work as well (not tested) - devices that pass the partitions via mtdparts bootargs are kept as is - gl-b2200 has a weird pcie wifi device (vendor claims 9886 wave 2. But firmware-extraction was for a wave 1 device?!) Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
* ipq40xx: remove model name from LED labelsAdrian Schmutzler2020-10-07
| | | | | | | | | | | Like in the previous patches for ath79 and ramips, this will remove the "devicename" from LED labels in ipq40xx. The devicename is removed in DTS files and 01_leds, and a migration script is added. While at it, also harmonize capitalization of wlan2G/wlan5G vs. wlan2g/wlan5g.

* ipq40xx: consolidate DTS filesAdrian Schmutzler2020-06-23
The DTS files in files-4.19 and files-5.4 are exactly identical except for one file (qcom-ipq4018-emr3500.dts), which is only present for 5.4. Since there is no point in maintaining all these identical files twice, this patch moves them to the "files" directory. If there ever was a new kernel with substantial DTS changes, a new folder would need to be introduced anyway and could easily be done. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
