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.

# Set WS=4 for both nCS0 and nCS1, matching what the official C155/156 fw sets

# We need to switch the CS4/ADD22 pin from its default function of CS4
# to the needed ADD22, to access the 8 MiB of flash.  Compal's C155/156
# in-flash boot code does this setting, but let's do it ourselves too.

# We don't mess with the FFFF:FB10 register on C155/156, i.e., we
# leave the "enable boot ROM" setting established by compalstage.
# Unlike C139, C155 and C156 phones do have working flash mapping
# at 0x03000000, so we use that.
