6eb5e8b602 main: rotor: erase immediately after send
- improves trace diagnostic output by moving cursor back over the
the rotor before a diagnostic message has a chance to be printed.
there is still a race condition, but it is much better.

a5d537973d cardem: reset the uC in case of USB disconnect
This fixes the firmware USB interface somehow getting stuck
after a USB disconnect/reconnect without power cycle.

Right now there are a number of things we only execute the first time we
reach USBD_STATE_CONFIGURED, but not at any subsequent such event.

It's also rather clear that this doesn't really show in simtrace2 as it
is bus-powered. And it doesn't show on OWHW as we don't have any USB
unplug situations of the USB between the on-board traces of USB host and
SAM3S.  So this really only is relevant to QMOD.

A cheap and dirty work-around is to simply reset the entire uC every
time a USB unplug happens.

039680a8d4 cardem: set more reasonable interrupt priorities
the ISO7816 UARTs have highest priority, while console has lowest.

remaining sources (USB, ADC, GPIO) are in between.

f721e69bc1 treewide: remove FSF address
Remove the paragraph about writing to the Free Software Foundation's
mailing address. The FSF has changed addresses in the past, and may do
so again. In 2021 this is not useful, let's rather have a bit less
boilerplate at the start of source files.

4fe93be725 introduce support for new ngff_cardem board
This adds support for the new ngff_cardem board, a board that
basically combines a ngff breakout board with a built-in SIMtrace2.

Cardem works, but depending on the modem it might need a adjusted ATR to
ensure a lower baud  rate is used by the modem, high rates might lead
to weird power cycling of the card after a few transfers.

Trace was also tested and appears to work as expected.

752bc7f4b5 card_emu: Use USART timeout for waiting time
Instead of using the timer/counter peripheral to handle the waiting time
and corresponding timeout, the USART peripheral internal timeout
mechanism is used.

This is particularly important for the SIMtrace board since there
(contrary to other boards) the I/O signal is not wired to a TIO pin
of the timer/counter block, and hence Rx/Tx data cannot reset that
timer/counter.

As a result of this migration, cardem is now supported not only on
owhw + qmod, but also on the simtrace board.

The guts of this change have been lifted out of Change-Id
Ibcb2c8cace9137695adf5fb3de43566f7cfb93b5 by Kevin Redon, which was
unfortunately touching various different topics at the same time and
hence was split up. Some improvements are the introduction of the
ENABLE_TX_TIMER_ONLY mode, which avoids the USART interrupt handler
getting hammered with TXRDY between release of RST and start of the ATR.

01868775ba Revert "add ISO 7816-3 library to remsim project"
This reverts commit 4a58c08d67.

The code replicates to a large extent what is already present in iso7816_fidi.c
and I have serious doubts about the correctness of the computation in
its iso7816_3_calculate_wt() function.

e3b2de45c4 firmware: move printing of welcome banner to common function print_banner()

also printed.

9d90d284ed Use system include <foo.h> notation for libosmocore headers
the curent local copies of libosmocore headers + source is a temporary
hack anyway. We should instead rely on a system-wide install of
libosmocore cross-compiled for arm-none-eabi.  But leave that as a
second (later) step beyond this patch.
