* generic: platform/mikrotik: use MTD notifierDenis Kalashnikov2022-01-13
| | | | | | | | | | | | | | | | | | | | If the SPI probe is sufficiently delayed, the routerboot driver may fail to init as the routerboot partitions are not yet available. Register an MTD user notifier instead of doing straight init so that the init subroutines are only executed when the target MTD partitions are present. Because the init/exit routines can now be called outside of the kernel normal init/exit calls, they cannot be jettisoned and must always be available: the __init and __exit qualifiers are thus removed.

* generic: platform/mikrotik: release mtd device after useThibaut VARÈNE2021-05-12
| | | | | | | | | | | | The code uses get_mtd_device_nm() which must be followed by a call to put_mtd_device() once the handle is no longer used.

* generic: platform/mikrotik: implement multi caldataThibaut VARÈNE2020-11-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MikroTik recently changed again the way they store wlan calibration data on devices. Prior to this change, ERD calibration data for all available radios was stored within a single identifier node ("tag" in RouterBoot parlance). Recent devices have been seen with calibration (and BDF) data stored in separate identifiers within LZOR packing for each radio: this patch addresses this by: 1) ensuring that both variants are properly supported, 2) preserving backward compatibility with existing data consumers, 3) allowing for more than 2 calibration blobs to be exposed via sysfs. Specifically, before this patch, the driver would provide a single sysfs file named /sys/firmware/mikrotik/hard_config/wlan_data that contained whatever calibration data found on the device's flash. After this patch, when executed on a device that uses the old style storage, this behavior is unchanged, but when executed on a device that uses new style storage (for either traditional "ERD" packing or "LZOR" packing), the driver replaces that single file with a folder containing one or more files each containing the data encoded within individual identifiers. As far as OpenWRT is concerned, this means that for devices which are known to exist with both styles of data storage, a suitable hotplug stub could look like this for e.g. the second radio: wdata="/sys/firmware/mikrotik/hard_config/wlan_data" ( [ -f "$wdata" ] && caldata_sysfsload_from_file "$wdata" 0x8000 0x2f20 ) || \ ( [ -d "$wdata" ] && caldata_sysfsload_from_file "$wdata/data_2" 0x0 0x2f20 ) This patch has been tested with LZOR old and new style packing on ipq4019, and with old style on ath79.

* generic: routerboot sysfs: add support for soft_configThibaut VARÈNE2020-05-28
| | | | | | | | | | | | | | | | | | | This driver exposes the data encoded in the "soft_config" flash segment of MikroTik RouterBOARDs devices. It presents the data in a sysfs folder named "soft_config" through a set of human-and-machine-parseable attributes. Changes can be discarded by writing 0 to the 'commit' attribute, or they can be committed to flash storage by writing 1. This driver does not reuse any of the existing code previously found in the "rbcfg" utility and makes this utility obsolete by providing a clean sysfs interface. Like "rbcfg", this driver requires 4K_SECTORS support since the flash partition in which these parameters are stored is typically 4KB in size.

* generic: routerboot sysfs platform driverThibaut VARÈNE2020-05-08
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.
