+# This configuration is intended to be applicable to all of C11x, C123,
+# C139 and C140.  The "plain" version of compalstage selected below
+# should work for all C11x/123; it will also work on C139/140 phones
+# that had the simpler boot code flashed into them, as will be used for
+# FreeCalypso.  When running loadtools with this config on C139/140
+# phones that still have the "official" fw in them, one will need to
+# specify -h compal -c 1003 to use the inefficient ~15 KiB version of
+# compalstage.

+# Whether we are breaking in through compalstage (as above) or through
+# tfc139, the re-enabled Calypso boot ROM is used to load our loadagent
+# into IRAM.  The boot ROM will autodetect the Calypso input clock as
+# 26 MHz (physical reality) when entered through compalstage, or as
+# 13 MHz when entered through tfc139 - the latter results from the
+# original fw setting bit 7 in the FFFF:FD02 register (VTCXO_DIV2),
+# which the boot ROM does not clear.
+#
+# However, the following configuration will result in the ARM core
+# being clocked at 52 MHz in both cases.
