+# Openmoko's GTA01/02 modem design is based on earlier Calypso phone or modem
+# designs by FIC, going back to 2004 according to dated comments in OM's FLUID
+# devices.txt file, and that parent design originally supported bigger flash
+# chips than the ones used in mass-produced GTA01/02 units.  The latter have
+# Samsung K5A3240CTM or K5A3281CTM chips populated in them (4 MiB of flash,
+# 512 KiB or 1 MiB of RAM), but the PCB footprint actually fits a 16 MiB flash
+# chip (Spansion S71PL129J), with the second flash chip select wired to Calypso
+# nCS4.  That devices.txt file also indicates that this nCS4 wiring was used
+# in FIC's 2004 design as well.
+#
+# This init script sets up Calypso MEMIF to access this maximum possibility of
+# 16 MiB of flash (in this particular wiring) or any subset thereof; it may be
+# needed if some early GTA01 prototype devices still had the bigger flash in
+# them or if someone finds an earlier (pre-Openmoko) FIC phone or modem.
