# 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.
