+# 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.
