gsm-fw/gpf/conf/gsmcomp.c: increased max partition in the voice-only config The code we got from TCS211 had the maximum prim pool partition size set to 900 bytes in the voice-only config (no FAX_AND_DATA, no GPRS) and to 1600 bytes in every other config. As it turns out, this "minimized" config breaks when the AT command interface is used with %CPI enabled, as the responsible code in ATI does an ACI_MALLOC of 1012 bytes. TI may have considered this case to be unsupported usage (perhaps they didn't care about the combination of a voice-only PS with AT command control), but we do want this use case to work without crashing. Solution: I made the largest prim pool the same as it is with FAX_AND_DATA: 3 partitions of 1600 bytes.

# This is a modified version of the gcc/config/arm/t-arm-elf file
# from gcc-4.5.4.  It has been modified by Spacefalcon the Outlaw
# for the FreeCalypso project; the changes are in the multilib
# configuration:
#
# a) The fpu multilib has been commented out
# b) The -mthumb-interwork multilib has been uncommented
