Andreas.Eversberg 9359a91504 Moved layer 1 <-> layer 2 interface from main.c to a seperate file of
liblayer23. Other applications using liblayer23 don't need to re-implement it.

Messages from layer 1 are not freed in layer2_read() anymore. They will be
freed by the upper layers. The layers may also decide to queue or to forward
the messages. In general: A message is always discarded by the message handler
and not after calling the message handler.

Feel free to help us by extending the code.  Always make sure to
send back all your patches to the baseband-devel@lists.osmocom.org
mailing list - Free Software is all about sharing.

== src/shared/libosmocore ==

is a library of various utility routines, including linked lists,
message buffers, bit-vectors, memory allocator, signals, select loop
handling, timers - as well as some more specifically GSM related things
like a TLV parser, a Comp128V1 implementation and utility functions for
RSL (TS 08.58) and CC/MM/RR (TS 04.08).

libosmocore is maintained in git://git.osmocom.org/libosmocore.git, so

	DO NOT DIRECTLY COMMIT TO libosmocore IN THIS REPOSITORY!

We simply maintain a copy (synchronized by git-subtree) in this
repository for the ease of building and to make sure everyone is using
the proper/compatible version of libosmocore

Please note, whatever you add to libosmocore will need to build as a
Linux userspace program (using glibc) just as well as on the OsmocomBB
embedded target without OS.  So please refrain from using fancy
functions.


== src/target/firmware ==

The firmware is what we build for the actual target (phone).  It was
written with some idea of modularity in mind, i.e. we have

 * Ti Calypso specific code in calypso/
 * Analog Baseband code in abb/
 * RF Mixer code in rf/
 * Layer1 code in layer1/
 * NOR flash handling in flash/
 * LCD display handlin in display/
 * minimal C-Library code in lib/
 * communications utility routines in comm/
 * Board (phone model/family) specific code in board/
   * board/compal_e88 is the Motorola C115-C124 family
   * board/compal_e99 is the Motorola C155 family
 * Applications (each app builds one firmware image) in apps/


== src/target_dsp/calypso ==

This is where we keep some (assembly) code that we wrote for
the DSP that is part of the Caylypso DBB.

== host/layer23 ==

The Layer2 (LAPDm / TS 04.06) and Layer3 (CC/MM/RR / 04.08)
implementations, as they are growing.
