Without the delay we would fill the sercomm buffer faster than its
content can be sent, and the phone would end up in a panic and hang.

This attribute is toggled with the RTC interrupt, which is disabled
in layer1_init(). If an interrupt between rtc_init() and layer1_init()
occured, the display of the E88 phones remained inverted

This is for being able to read the whole flash on devices that use the bootrom,
and also fixes flash detection on the C139/C140/J100i

* This might be a workaround for a compiler bug

Newer GCC with GNU LIBC do not like our minimalistic version of
stdint.h and will have conflicts. Older GCC with older C Libs do
not have a stdint.h yet and the #include_next trick is failing. To
make matters worse NEWLIB does not export its version via the
pre-processor.
We will have to guess once more about the compiler. This code now
assumes that if we have a GCC < 4 that it does not have a stdint.h
and we will not try to include the next stdint.h file.
Don't assign to the variable given as argument. This prevents
clobbering the local 'reg' variables in uart_reg_{read,write}(),
which would in turn prevent the latch bits from being restored
correctly.

Store old_lcr only when switching to LCR == 0xBF. We don't want
to clobber old_lcr when switching back, otherwise we can't restore
the previous LCR value.

This works for both the default ROM bootloader and for our
custom one.
This will allow to implement easy patch loading.

Altough quite counterintuitive, the TCH_A task does some voice coding
work ... at least during TCH/H subchannel 1 ...
Go figure ...

Otherwise, when it reached AFC_RETRY_COUNT, no new FB0 tasks
were scheduled, and you needed to restart the phone in order to
successfully sync to a cell

The initial bringup is mainly Dieter Spaar's work. I took the
logic and rewrote it, adapting to later scheduler changes and
adding support for several other things (tch_mode, initial HR
support, various cleanup, ...).

At this point in the code, we don't know if we're TCH/H or TCH/F, so
just store the speech mode and we'll figure out what to tell the DSP
in the task code itself.

If the task interrupted because of a reset, an allocated msgb
will be present and we need to free it instead of just loosing
the reference to it.

Copying to/from the DSP API shared memory must be done using
16 bits word only. Using those method, we avoid the hassle of
repeating the code when we copy buffer back and forth.
API address must be 16 bits aligned but for our purpose, it's
good enough.

For the host build the local_irq_save/_restore is a NOOP
and the compiler warns about the unused flags variable. Cast
it to void to avoid compiler warning.
