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.
* port 'mobile' application to new l1ctl_tx_fbsb_req()
* make sure we have a proper downlinke header in front of l1ctl_fbsb_resp
* remove duplicate band_arfcn member of struct l1ctl_fbsb_resp
* reset the AFC to its default value when starting new FBSB task
* remove bogus l1s.sb.{synced.count} variables
* allocate msg and send l1ctl_fbsb_resp() only from process context, not FIQ
* properly report SNR and BSIC in fbsb_resp
* introduce arbitrary SNR thresholds for FB0->FB1 and FB1->SB switching
We really want to have those two as distinct operations - and we
want proper state machines in L1 to quickly return if they've
managed to acquire a FB or SB or not. Otherwise scanning will
take ages...
This code now introduces a new l1ctl_fbsb_req that is sent via
L1CTL to ask for a bitmask of FB0/FB1/SB operations. The actual
FB0/FB1 detection now no longer runs for 500 TDMA interrupts
but completes as soon as we either know there is no FCCH,
or that our frequency error is smaller than a caller-specified
threshold.
FB0/FB1 are already working, SB is not yet, sorry.
The romloader of the MT6223 uses more of the internal SRAM
than the loader of the MT6227, thus we need to change the load
address.

Currently the switch to a higher baudrate is missing, which has
to be done by a direct UART autobaud register write, plus sending
an autobaud sample.
As a result, the maximum download speed is currently 19.200 Baud.

For now just copied over the compal_e88 init.c and adapted the RF
frontend functions. For osmocon to work with the GSM download cable
SERCOMM_UART_NR and CONS_UART_NR need to be switched.
the l1s signal was an old mechanism between l1test and the layer1
before we introduced the L1CTL protocol. This commit removes all
leftover references to it.
It also disables the l1test app, as it would no longer work without
major modifications (using l1ctl from within the phone).
The idea is that the L1S part can schedule a completion handler which
will then execute in the asynchronous L1A part. This should keep the
FIQ priority L1S extremely short, deferring most of the work into
the L1A part that runs in regular process context.
- Load and save of config now works.
- Network search is displayed on VTY and the result can be selected there.
- Manual/auto mode can be selected via VTY and saved.
It is now possible to show informations about:
- mobile
- subscriber
- received cell informations
Later it can be used to do configurations (phone's menu)
and trigger events, like dialing a phone number.
- Fixes on PLMN search and cell selection process.
- Fixes on radio ressource.
- ^C will cause IMSI detach when pressed the first time.
Pressing ^C again will cause termination of process at any time.
- Fixed reference to system informations. (did crash when re-selecting).
- Fix in cell selection state machine. (any re-selection).
- MCC, MNC, LAC change of cell now triggers re-selection.
- Fixed some paging issues. Empty pagings are not displayed anymore. Also paging is now possible when 'camping on any cell'.
The current code will scan frequencies, select a cell and camps on it.
No SIM is inserted. Paging requests and Immediate assginments can be seen.
When inserting a SIM card (uncomment it in app_mobile.c), location update
is triggered after selecting a cell. The RACH request is sent, an
Immediate assignment is received, the dedicated mode is requested.
Nothing happens then, because no confirm / abort of layer 2 is received.
