No subject

since it does not get used anywhere (unless you need append-ubi or do
some padding in the image). 

mksquashfs for example uses a separate
CONFIG_TARGET_SQUASHFS_BLOCK_SIZE value 
(which is usually 256 KiB or more) due to:

|https://github.com/Othernet-Project/squashfs-tools/blob/master/README#L350
|
|There are a large number of options that can be used to control the
|compression in mksquashfs.  By and large the defaults are the most
|optimum settings and should only be changed in exceptional circumstances!
|Note, this does not apply to the block size, increasing the block size
|from the default of 128Kbytes will increase compression (especially
|for the xz compressor) and should increase I/O performance too.  However,
|a block size of greater than 128Kbytes may increase latency in certain
|cases (where the filesystem contains lots of fragments, and no locality
|of reference is observed).  For this reason the block size default is
|configured to the less optimal 128Kbytes.  Users should experiment
|with 256Kbyte sizes or above.

I've also stumpled at this in the past with the RT-AC58U and MR33 and
I left the BLOCKSIZE at what was in the NAND's datasheet. That said,
it's OK either way.
