gsm-fw/L1: fix for the DSP patch corruption bug The L1 code we got from the LoCosto fw contains a feature for DSP CPU load measurement. This feature is a LoCosto-ism, i.e., not applicable to earlier DBB chips (Calypso) with their respective earlier DSP ROMs. Most of the code dealing with that feature is conditionalized as #if (DSP >= 38), but one spot was missed, and the MCU code was writing into an API word dealing with this feature. In TCS211 this DSP API word happens to be used by the DSP code patch, hence that write was corrupting the patched DSP code.

# 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.

compal-stage plain

# 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.
