# 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
