We now unlock the flash before reading the
extended ID (required for Spansion and Samsung
flash chips). These commands will be ignored
by Intel/ST flash chips, and this change has been
verified with all flash chips we support.
Furthermore, expose the API for reading the flash ID.

This commit adds polling of the TWL3025 PWON
signal. If the powerbutton is pressed on targets
that use it (Pirelli DP-L10, Huawei GTM900-B),
a normal keypad scanning cycle is started in order
to preserve the timing, required for the 500ms
power off press duration for example.

This allows us to detect power button presses on the Pirelli
DP-L10 and the Huawei GTM900-B module. Polling will only be
activated once the power button has been pressed and we received
the interrupt. The goal is to reduce the required amount of
TWL3025 register accesses to a minimum.

CBCH support in the firmware has been introduced almost at the same
time it was implemented in trxcon, and the same mistake was made
as described in Ia9a415628c659cbc2dd5dc65b875b7f935d6e211.
Despite Calypso based PHY does not support PDCH (GPRS channels),
let's avoid collisions and use the following cbits values:
0x19 / 0b11001 - MF_TASK_SDCCH4_CBCH on GSM_DCHAN_SDCCH_4_CBCH,
0x1a / 0b11010 - MF_TASK_SDCCH8_CBCH on GSM_DCHAN_SDCCH_8_CBCH.

All known TI GSM firmwares implement some kind of flash file system, or FFS.
We call it TIFFS (Texas Instruments FFS) because it is TI's invention.
TIFFS is a file system with a hierarchical directory tree structure, and
with Unixy forward-slash-separated, case-sensitive pathnames; the semantics
of "what is a file" and "what is a directory" are exactly the same as in
UNIX; and TIFFS even supports symlinks, although that support is a little
under-developed, and apparently no FFS symlinks were ever used in any
production GSM device. Thus the FFS implemented in TI-based GSM devices
(modems and "dumbphone" handsets) is really no different from, for example,
JFFS2 in embedded Linux systems.
The FFS in a GSM device typically stores two kinds of content:
- Factory data: IMEI, RF calibration values, device make/model/revision
ID strings etc. These files are expected to be programmed on the
factory production line and not changed afterward.
- Dynamic data written into the FFS in normal device operation: contacts,
settings / preferences, call history, received SMS, etc.
It should be noted that both Compal (Mot C1xx) and Foxconn (Pirelli DP-L10)
vendors moved their vital per-unit factory data out of the FFS into their
own ad hoc flash data structures, leaving their FFS only for less
critical data. However, we do enable TIFFS access for them anyway.
The location of TIFFS within the flash memory of a given GSM device is
defined by the firmware design of that device, but is always some integral
number of contiguous flash sectors.
- On Motorola/Compal C139/140 phones, the FFS used by the original
proprietary firmware occupies 5 sectors of 64 KiB each (320 KiB
in total), starting at 0x370000. C11x/123 use smaller FFS
configurations, whereas C155/156 seem to have switched to some
other FFS format, different from our familiar TIFFS.
- On the Pirelli DP-L10, the FFS used by the original proprietary
firmware occupies 18 sectors of 256 KiB each (for 4.5 MiB in total),
starting at the beginning of the 2nd flash chip select (0x02000000
in the ARM7 address space).
- On FCDEV3B (FreeCalypso hardware), the FFS is located in the first
8 sectors (of 256 KiB each) in the 2nd flash chip select bank,
which appears at 0x01800000 in the ARM7 address space.
- On the GTA01/02 GSM modem, FFS occupies 7 sectors of 64 KiB each,
starting at flash offset 0x380000.
For more information, please refer to the FreeCalypso project
documentation, from where this great contribution comes from.
Please note that existing MediaTek targets most likely use different
storage format as they have nothing from TI Calypso. Also, we don't
(yet) know the location of TIFFS on SE J100i and Compal E99 targets.
The TIFFS support is needed for the follow-up change, that
implements reading of the factory RF calibration values.

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.

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.

Unlike the DATA messages, traffic frames may have different length.
Instead of having fixed payload (i.e. TCH frame) length, let's
introduce a flexible array member. This would allow one to
calculate the frame length using the MSGB API.

According to GSM TS 05.02, there are two ways to enable CBCH:
a) replace sub-slot number 2 of CCCH+SDCCH/4 (comb. V),
b) replace sub-slot number 2 of SDCCH/8 (comb. VII).
Unlike SDCCH/8 (case b), CCCH+SDCCH/4 can be allocated on TS0
only, and shall not use frequency hopping. This means that
implementing CBCH support on SDCCH/8 would require much more
efforts than on combined CCCH+SDCCH/4, as in last case CBCH
messages can be received without the need to switch from
idle to dedicated mode.
This change introduces a new ccch_mode item, which should be
used by the higher layers to indicate presence of CBCH channel
on C0/TS0, so the PHY would enable decoding of CBCH messages
on CCCH+SDCCH/4 (case a) in idle mode.
Regarding to CBCH on SDCCH/8 (case b), it makes sense to
extend the 'l1ctl_dm_est_req', so it would be handled in
dedicated mode on request from the higher layers.

According to GSM TS 05.02, section 3.3.5, Cell Broadcast Channel
(CBCH) is a downlink only channel, which is used to carry the
short message service cell broadcast (SMSCB). CBCH is optional,
and uses the same physical channel as SDCCH. More precisely,
CBCH replaces sub-slot number 2 of SDCCH channels when enabled.
This change introduces the following CBCH related tasks:
- MF_TASK_SDCCH4_CBCH (CBCH on C0/TS0 SDCCH/4),
- MF_TASK_SDCCH8_CBCH (CBCH on SDCCH/8),
which are identified using the following Osmocom specific cbits:
- MF_TASK_SDCCH4_CBCH - 0x18 (0b11000),
- MF_TASK_SDCCH8_CBCH - 0x19 (0b11001).
The only way to enable these tasks at the moment is to send
L1CTL_DM_EST_REQ message with required cbits and tn.

The mframe_task2chan_nr() is used to get the channel number

when there is no matching channel number for a given task type.

Some time ago a broken fix was committed which
then has been reverted again in commit
1724003737.
The purpose of this line is to clear the uplink
flag from the ARFCN. So far this worked because
both gsm_arfcn2band() and gsm_arfcn2freq10()
already do this internally.

Previously, TCH frames coming from L1 were reordered to the RTP
format. Moreover, the implementation had a few problems:
- L1CTL is not the best place for such manipulations;
- payloads with other than FR codec were corrupted.
Let's use RTP-ordered payloads on the L1CTL interface,
performing TCH frame reordering at the firmware.
Please note, that actual FR reordering was moved to the firmware
as is, without any codec determination. This could be fixed in
a separate change.

Previously, the L1CTL_CRYPTO_REQ message contained only a ciphering
algorithm and actual Kc key to be used. The key length was
calculated manually using the MSGB API.
Let's avoid manual calculations here, as it may cause unexpected
behavior if the message structure is changed. Also, let's fill
the UL header with minimal information about a channel, which
is going to be encrypted.

This reverts commit 1724003737.
For some reason the "obviously broken" code is working, but the fixed
version is not. Let's go back to step 1 and analyze this in more
detail, but meanwhile make the code work again.
Some header files are auto-generated and are thus in the build
directory, not in the source directory. A cleaner way to handle this is
most likely to install libosmocore to some directory, but I don't want
to change the entire build process now.
Somebody (me?) wrote exclamation marks instead of pipe symbols.

"multiframe", the frame layout (used to compute neighbor
cell monitoring pattern) was uninitialized in TCH/H case.
This, in combination with gcc optimizing the
"switch(multiframe)"-statement into a LUT without bounds-
checking (since using an uninitialized value is undefined
behavior) caused neigh_task to be filled with an out-of-
bounds value, eventually crashing the TDMA scheduler.
