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.

# Most Leonardo boards will probably have Calypso C035 chips on them,
# but we know that some very early Leonardo boards had been built with
# Calypso C05B, thus we need to stay within the lower clock frequency
# limits of the latter.

# The following parameters go into the <p command sent to the boot ROM
pll-config 3/1		# 26 MHz in, PLL&DSP @ 78 MHz, ARM @ 39 MHz
rhea-cntl 0x00		# good for all Calypso platforms

# The remaining settings are carried out via loadagent commands
init-script cs2-4ws-8mb.init

# There had been many Leonardo board variants with different flash chips,
# including a version with a second flash chip select on nCS2 - thus nCS2
# is considered to be reserved for flash in the Leonardo family.
