When I do mtd1 + mtd2 + mtd3, I end up with 0x3d00000 instead of 0x4000000. Is that normal? Do you reserve a bit of space at the end or is it that rcw is not starting at 0?
I have given partition size n bootargs as mtdparts=20c0000.quadspi-1:5M(rcw),10M(test),46M(rootfs)
5 + 10 + 46 ==> 61M i.e. 0x3d00000.
I have just reserve the bit at the end, we can modify these settings also.

I have tried JFFS2 mounting with smaller partition size but still getting failure.
For partition size equal or less than 1MB, getting errors as
[ 25.044930] jffs2: Too few erase blocks (4)
Thus, need to have size more than 1MB.
For 2MB partition size getting error message from jffs2_scan_eraseblock().
root@ls1012ardb:~# cat /proc/mtd
dev: size erasesize name
mtd0: 04000000 00040000 "20c0000.quadspi-0"

mtd2: 00a00000 00040000 "test"
mtd3: 00200000 00040000 "rootfs"
root@ls1012ardb:~# mkdir /media/ram ; flash_eraseall /dev/mtd3
flash_eraseall has been replaced by `flash_erase <mtddev> 0 0`; please use it
