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 loadtool config is set up to address 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. # The following parameters go into the <p command sent to the boot ROM pll-config 4/1 # 26 MHz in, PLL&DSP @ 104 MHz, ARM @ 52 MHz rhea-cntl 0x00 # good for all Calypso platforms # The remaining settings are carried out via loadagent commands init-script fic.init # Flash global config and chip select base addresses flash dual-8M 0x03000000 0x02800000 # Perform a Iota poweroff when we are done exit-mode iota-off
