fc-loadtool help: improve language regarding 16 MiB flash chips
In FC project history, 16 MiB flash originally meant Pirelli DP-L10.
Then we got FCDEV3B with the same flash (our own design), but now we are
discovering more Calypso devices that used such large flash, both late
Calypso era (Sony Ericsson K2x0) as well as much earlier ones (FIC FLUID
devices.txt file with 2004 dates, Leonardo+ rev 5). Hence we need to
migrate to more generic or neutral language in associated documentation,
without giving elevated status to specific examples that drove our
early project history.

# 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. w16 fffffb00 00A4 w16 fffffb02 00A4 w16 fffffb0a 00A4 w16 fffef006 0008
