armio.c: set GPIO2 output high initially On TI-canonical platforms GPIO2 is DCD modem control output. In TI's original code the AI_InitIOConfig() function called from Init_Target() would configure GPIO2 as an output and set the initial output value to low, but then the init code in uartfax.c called from Init_Serial_Flows() would immediately change it to high, corresponding to DCD not asserted. The result is a momentary asserted-state glitch on the DCD output. The present change eliminates this glitch, setting DCD output to not-asserted initially like it should be.

# This patch applies to the Init_Target() function in the init.obj module in
# main.lib; it is an example of how this code will need to be patched for
# running on our own future FreeCalypso hardware if we choose to use the same
# Spansion S71PL129NC0 flash+pSRAM MCP as used in the Pirelli DP-L10 and use
# the same memory timings as set by Pirelli's firmware.
