annotate src/g23m-gprs/llc/llc_ul.c @ 640:16eb1b9640dc
target gtm900 renamed to gtm900mgc2
This change reflects the fact that the build target in question supports
MGC2GSMT hardware only, and will NOT work on other hw that confusing bears
the same end user name of GTM900, neither the LoCosto-based GTM900-C
nor the Calypso-based MG01GSMT that has a different and incompatible RFFE.
If we ever get our hands on a piece of MG01GSMT hw and add support for it,
that other target will be named gtm900mg01.
