7d33aedd10 generic: platform/mikrotik: add wlan lz77 decompress
A number of new (or with recently updated caldata)
Mikrotik devices are using LZ77 magic for wlan tag hard_config data.
New devices include the Chateau LTE12 [1], and ax devices [2]
Newly factory flashed devices may include the hap ac3 [3]

This can be seen in decoded OEM supout [4] dmesg:
"radio data lz77 decompressed from"…

Investigating an arm RouterOS flash.ko module, and supplied example
hard_config dumps, the format was guessed via decompilation and live
debugging [5]. This decoder was then built from the guessed format
specification.

debug prints can be enabled in a DYNAMIC_DEBUG kernel build via the
kernel cmdline:

        chosen {
-               bootargs = "console=ttyS0,115200";
+               bootargs = "console=ttyS0,115200 dyndbg=\"file drivers/platform/mikrotik/* +p\"";
        };

758f320ebe mt7621: enable CONFIG_MTD_UBI_NVMEM, CONFIG_NVMEM_LAYOUT_U_BOOT_ENV
Enable above drivers for mt7621 targets. They are needed for retrieving a MAC
address stored in a U-boot environment residing on an UBI volume.

73a9f9f857 generic: platform/mikrotik: add NVMEM layout driver
Currently, information from MikroTik hard_config is only available via
sysfs, meaning that we have to rely on userspace to for example setup MACs.

So, lets provide a basic NVMEM layout based driver to expose the same cells
as sysfs driver exposes.

Do note that the we dont extract the WLAN caldata and BDF-s at this point.

d529ac5da8 ramips: mt7621: switch trx parser to parser_trx from mtdsplit
Switch trx parser to parser_trx of Linux Kernel from mtdsplit_trx to
split firmware partition using model-specific trx magic number on
some Buffalo devices.
This change is tested on Buffalo WSR-2533DHPL.

ccd50abd9f ramips: add back the gdma driver
The gdma driver has been removed from the upstream. Let's move it
to the local files. This patch also removed unsupported compatible
string and sub-target.
