generic: platform/mikrotik: fix LZOR support

2020-05-16T18:32:20Z

31e99fe3da which introduced this code was unfortunately untested. This commit fixes a number of issues and works around the fact that in this particular scheme, the LZO payload may be padded at the end which will trigger a harmless lzo decompression error. This commit also disambiguates the debug printks. Tested-by: Robert Marko Signed-off-by: Thibaut VARÈNE Fixes: 31e99fe3da ("generic: platform/mikrotik: support LZOR encoding") (cherry picked from commit 2ea481193c1654c9cb42aa0331cdbc4570783e26)

ar71xx: remove hard-coded folder name from Mikrotik RB upgrade

2020-05-12T15:48:02Z

So far, specifying "BOARD_NAME := routerboard" is required by the upgrade code of Mikrotik NAND devices, as "sysupgrade-routerboard" is hardcoded in platform_do_upgrade_mikrotik_rb(). This patch replaces the latter with a grep for the name like it is already done in nand_upgrade_tar() in /lib/upgrade/nand.sh. This should enable upgrades from ar71xx to ath79 without setting BOARD_NAME for the latter. Signed-off-by: Adrian Schmutzler (backported from commit 281785d74fcc70153c0741be36ee1f9d05e74f6f)

ar71xx: mikrotik: bypass id check in __rb_get_wlan_data()

2020-05-12T10:43:38Z

The id parameter in __rb_get_wlan_data() was incorrectly used on the assumption that id "0" would always be tied to ath9k with RLE encoding and positive id (in fact, only id "1" was valid) would always be tied to ("external") ath10k with LZO encoding. Newer hardware revisions of supported devices prove this assumption to be invalid, with ath9k caldata being now wrapped in MAGIC_ERD and LZO compressed, so disable this check to allow newer hardware to correctly decode caldata for ath9k. Since ath10k caldata is no longer pulled from this implementation, this commit also disables the publication in sysfs to avoid wasting memory. Note: this patch assumes that ath9k caldata is never stored with the new "LZOR" encoding scheme found on some ath10k devices. Signed-off-by: Thibaut VARÈNE

Some newer MikroTik RouterBOARD devices use a new encoding scheme for their WLAN calibration data. This patch provides support for decoding this new scheme. Signed-off-by: Thibaut VARÈNE

generic: routerboot sysfs platform driver

2020-05-12T10:43:38Z

This driver exposes the data encoded in the "hard_config" flash segment of MikroTik RouterBOARDs devices. It presents the data in a sysfs folder named "hard_config". The WLAN calibration data is available on demand via the 'wlan_data' sysfs file in that folder. This driver permanently allocates a chunk of RAM as large as the "hard_config" MTD partition (typically 4KB), although it is technically possible to operate entirely from the MTD device without using a local buffer (except when requesting WLAN calibration data), at the cost of a performance penalty. This driver does not reuse any of the existing code previously found in routerboot.c. This driver has been successfully tested on BE (ath79) and LE (ipq40xx and ramips) hardware.

ath79: dts: add missing 'serial0' alias for TP-Link TL-MR3040v2

2020-05-11T09:17:59Z

Out of all devices currently supported based on AR9331 chipset, this one had the 'serial0' alias missing. Add it to fix setting of /dev/console and login shell on the onboard UART. Signed-off-by: Lech Perczak (cherry picked from commit 94f344997769a9a18e2d73574d9d17785828955d)
