rvinterf backslash escape: introduce libprint The new helper function library named libprint is meant to replace the badly misnamed libg23, and will soon contain functions for printing all of the same kinds of GPF TST packets that are now handled in libg23. However, we are also moving safe_print_trace() from libasync to this new library, and changing it to emit our new backslash escape format.

# 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.
