doc/Host-tools-overview: tiffs-mkfs description updated The first version of tiffs-mkfs did not include a journal file in the created FFS, expecting the firmware to create it on first boot. All historical firmwares prior to a recent FC fix (2020-05) contain a bug in that code path, thus images made with the first version of tiffs-mkfs were only acceptable to very recent FC firmwares. tiffs-mkfs has now been extended to include an empty journal in the created FFS, thus the restriction of working with recent fw only has been lifted.

# This loadtool init script provides memory interface register setup
# for targets which fit the following criteria:
#
# Classic chip select arrangement: nCS0 for flash and nCS1 for XRAM
# 4 wait states are to be used (register setting 00A4)
# 8 MiB flash chip may be present, thus ADD22 needs to be enabled
