The pflash error "isn't erase block aligned" appears when the check for
64k erase blocks is turned on, and the specified address (0x20100000 in
this case) isn't 64k aligned. There may be more details about if there's
a way to switch this check on and off in the skiboot mailing list
(https://github.com/open-power/skiboot) where the pflash tool
originates.
An alternate tool would be "dd"
(http://man7.org/linux/man-pages/man1/dd.1.html).
The command could look like:
dd if=fitImage.bin of=/dev/mtd0 --skip=0x20100000 -bs=1
