FCDEV3B (stands for "FreeCalypso development board, triband") is a
GSM mobile station development board by FreeCalypso project. The
board features the same legendary TI Calypso GSM MS chipset that
was used in commercial GSM/GPRS modems such as Openmoko's, and
functions as a standalone (or "bare") GSM modem.
For more information, please see the project's web side:

The ability to read the second half of flash on E99 is needed
for the follow-up change, that implements reading of the
factory RF calibration values.

Each given Mot C1xx phone is made either for 900+1800 MHz, in which
case only the DCS Rx port is connected, or for 850+1900 MHz, in which
case only the PCS Rx port is connected. Let's tell the TRF6151 driver
that both DCS and PCS ports are connected, so that the same binary
build can be used on both EU-band and US-band C1xx phones.
If one needs to tune the TRF6151 receiver out of spec, or at least
outside of the DCS/PCS Rx SAW filter's legitimate passband (or if
the SAW filter was changed or removed), then the rffe_get_rx_ports()
function might be changed to indicate which Rx port is physically
connected: PORT_DCS1800 only or PORT_PCS1900 only.

Most Calypso peripheral interface signals are unconnected on
Openmoko GTA0x. Let's configure them to be GPIOs in IO_CONF_REG,
then configure them to be outputs in IO_CNTL_REG, then set
the outputs to 0 in ARMIO_LATCH_OUT.

As we do iterate over all entities in the BA list, it makes more
sense to print each one separately instead of printing the last
one. Moreover, as soon as the iteration is finished, *ba points
to some zero-initialized part of memory:
gsm322.c:5170 Write stored BA list (mcc=000 mnc=000 Marshall Islands, 000)
After this patch:
gsm322.c:5162 Write stored BA list (mcc=250 mnc=99 Russian Federation, Beeline)
gsm322.c:5162 Write stored BA list (mcc=250 mnc=01 Russian Federation, MegaFon)
gsm322.c:5162 Write stored BA list (mcc=250 mnc=02 Russian Federation, MTS)
gsm322.c:5162 Write stored BA list (mcc=544 mnc=31 Serbia, Telenor)

Both l1ctl_link_init() and trx_if_open() do accept 'tall_ctx' now,
so there is no need to expose the root context anymore. For
logging initialization, we can just pass a pointer.
Change-Id: I7a2231eb880a995d3296b94481a7799e6ff07489

The main changes are:
- return pointer to the allocated l1ctl_link or NULL,
- accept the talloc context as 'tall_ctx' argument.

- rename argument 'port' to 'base_port'.

Since Ibff31fb3a958a714c828d0dea7e87d47f778fd80, fake_trx.py does
support multiple transceivers. Let's update its description.

Since fake_trx.py can handle multiple transceivers, it may be useful
to name transceivers. If transceiver has some name, it will appear
in logging messages, for example:
[INFO] transceiver.py:104 Init transceiver 'BTS@127.0.0.1:5700'
[INFO] transceiver.py:104 Init transceiver 'MS@127.0.0.1:6700'
[INFO] transceiver.py:104 Init transceiver '127.0.0.1:5700/1'
This change additionally assigns names to the both default
transceivers, and extends the '--trx' option with ability
to specify some name, for example:
--trx foo@127.0.0.1:5700 or --trx bar@127.0.0.1:5700/1
--trx ipv6@[2001:0db8:85a3:0000:0000:8a2e:0370:7334]:6700

One can confuse TRX control interface with libosmoctrl's one.
TRX toolkit is not using libosmoctrl, and will never do. But,
in order to avoid this confusion, and potential confusion of
DATA interface, let's call them 'TRXC' and 'TRXD' in logging.

Since fake_trx.py can handle multiple transceivers, it makes sense
to print some info in logging messages about transceivers they
belong to. This acvieved by defining __str__() for Transceiver.
Some examples:
[DEBUG] ctrl_if_trx.py:83 (127.0.0.1:5700) Recv POWEROFF cmd
[INFO] ctrl_if_trx.py:85 (127.0.0.1:5700) Stopping transceiver...
[DEBUG] ctrl_if_trx.py:95 (127.0.0.1:5700/1) Recv RXTUNE cmd
[DEBUG] ctrl_if_trx.py:102 (127.0.0.1:5700/1) Recv TXTUNE cmd
[DEBUG] ctrl_if_trx.py:155 (127.0.0.1:5700/1) Ignore CMD SETTSC

There should be no code in run() that does initialization,
__init__() is the best place for this. This change allows
to import the Application class from fake_trx.py, and
run it from script (e.g. for testing).

The (BT)SAP (Bluetooth SIM Access Profile) is a part of Bluetooth
specifications, that defines the protocol and procedures that
shall be used to access a smart card (usually GSM SIM) via
a Bluetooth link.
The profile defines two roles:
- Server - the side that has direct access to a smart card.
It acts as a SIM card reader, which assists the Client
in accessing and controlling the smart card.
- Client - the side that accesses and controls the smart card
inside the Server through the connection with Server.
Typical examples of a Server are a simple SIM card holder or
a portable phone in the car environment. A typical example of
a Client is a car phone, which uses a subscription module in
the Server for a connection to the cellular network.
OsmocomBB implements the Client role providing abstract SAP
interface API to the higher layers. Instead of Bluetooth,
a UNIX socket is used to communicate with a Server.
The previous implementation of (BT)SAP interface was incomplete
and hard to maintain. This change (re)implements it almost from
scratch on top of the Osmocom FSM framework.
Besides that, the most significant changes are:
- The implementation is separated into three parts:
- sap_interface.{c|h} - public SAP interface API,
- sap_proto.{c|h} - SAP protocol definition,
- sap_fsm.{c|h} - SAP FSM implementation.
- Both 'sap_message' and 'sap_param' structures follow the
SAP message format definition according to 5.1 and 5.2.
- The message parsing is done more carefully in order to
prevent buffer overflow and NULL-pointer dereference.
- Introduced public API for getting / adding message
parameters, and checking the ResultCode.
- Introduced public API for opening / closing a connection
with the server, powering on / off and resetting the SIM
card, sending ATR and APDU.
- Introduced a call-back for handling the response message.
- Card reader state is also a part of the public API.
The new implementation was tested against softsim [1]. The
only limitation is Server-initiated Release, that allows the
Server to 'ask' a Client to release connection as soon as
communication with the smart card is finished. This is not
implemented (yet), and leads to immediate release.

It seems in Ice44e2b22566b3652ef6d43896055963b13ab185 I forgot
to do this, so all measurements triggered by MEASURE command
were incorrect (always noise). Let's fix this!

Since Ice44e2b22566b3652ef6d43896055963b13ab185 is merged, the class
hierarchy has become much more flexible, so it's possible to create
multiple Transceiver / FakeTRX instances and distribute bursts using
a single instance of BurstForwarder.
This change introduces a new command line option, that can be used
to specify additional transceivers. Please note that fake_trx.py
still initializes a pair of BTS and BB transceivers by default.
The new option has the following format:
--trx REMOTE_ADDR:BASE_PORT[/TRX_NUM]
Some examples for IPv4 and IPv6:
--trx 127.0.0.1:5703
--trx [2001:0db8:85a3:0000:0000:8a2e:0370:7334]:6703
If optional TRX_NUM > 0 is specified, e.g.:
--trx 127.0.0.1:5700/1
then this transceiver is considered as a child of another one.
See I7e97b7f32dde7ab74779133e9d7504f1d0fce60c for details.

A BTS can (optionally) have more than one transceiver. In this case
additional (let's say child) transceivers basically share the same
clock source of the first transceiver, and being powered on / off
as soon as the first transceiver is powered on / off.

It was discovered that using an empty list as default argument
value does result into the cross-reference, i.e. all instances
of BurstForwarder would reference the same trx_list object.
This is not an expected behaviour, let's fix this.

Passing NULL to sap_msg_free() is not only meaningless, but also

Due to a mistake, average RSSI value of received bursts was not
converted to GSM RX level (range 0..63), so trxcon has been
sending incorrect values to the higher layers.
Let's fix this, and also prevent possible division by zero.

There are several SIM card interfaces, two of which:
- GSM_SIM_TYPE_L1PHY (using built-in SIM reader of the L1 PHY),
- GSM_SIM_TYPE_SAP (using remote reader via (BT)SAP protocol),
can actually deal with a physical SIM card. But, for some reason,
only GSM_SIM_TYPE_L1PHY was considered as such. Let's also get
along with GSM_SIM_TYPE_SAP for the following procedures:
- PIN management and verification,
- FPLMN / LOCI updating,
- A3 authentication.

Since we have two ways to interact with a physical SIM:
- using built-in SIM reader of the L1 PHY (via L1CTL),
- using remote reader via (BT)SAP protocol,
name 'GSM_SIM_TYPE_READER' looks quite confusing. Let's rename it
in order to explicitly indicate the role of L1 PHY.
