## To determine parameters' values, run "ubiattach -m 6 /dev/ubi_ctrl"
## (assuming the rootfs device is /dev/mtd6). Here's an example:
# # ubiattach -m 6 /dev/ubi_ctrl
# [ 28.640396] UBI: attaching mtd6 to ubi0
# [ 53.000817] UBI: scanning is finished
# [ 53.126052] UBI: attached mtd6 (name "filesystem", size 4079 MiB) to ubi0
# [ 53.133109] UBI: PEB size: 524288 bytes (512 KiB), LEB size: 516096 bytes
# [ 53.140149] UBI: min./max. I/O unit sizes: 4096/4096, sub-page size 4096
# [ 53.146895] UBI: VID header offset: 4096 (aligned 4096), data offset: 8192
# [ 53.153931] UBI: good PEBs: 8139, bad PEBs: 20, corrupted PEBs: 0
# [ 53.160263] UBI: user volume: 1, internal volumes: 1, max. volumes count: 128
# [ 53.167444] UBI: max/mean erase counter: 2/1, WL threshold: 4096, image sequence number: 0
# [ 53.175872] UBI: available PEBs: 4113, total reserved PEBs: 4026, PEBs reserved for bad PEB handling: 140
# [ 53.189399] UBI: background thread "ubi_bgt0d" started, PID 217
# UBI device number 0, total 8139 LEBs (4200505344 bytes, f GiB), available 4113 LEBs (2122702848 bytes, f GiB), LEB size 516096 bytes (f KiB)
# --min-io-size: see "min./max. I/O unit sizes: " in the ubiattach output
# --leb-size: see "LEB size:" in the ubiattach output
# --max-leb-cnt: see "total <n> LEBs" in the ubiattach output, where <n> is the number you want
# --peb-size: see "PEB size:" in the ubiattach output (pick the value in bytes)
# --sub-page-size: see "sub-page size" in the ubiattach output
