# 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.
