Features:
- Uses the SPI bus to communicate with the card
- Detects and safely rejects SDSC (<= 2 GiB) cards
- Uses the optional CRC support for data integrity
- Retries resumable errors like CRC failure or temporary IO failure
- Works well with ELMFAT
- When used on a device with a FIFO or DMA, achieves >= 310 KiB/s on a
4 MHz bus
Tested on a mix of SanDisk, Samsung, 4V, and ADATA cards from 4 GiB to
32 GiB.

Change arg_len to be u16_t in shell_history_get since it is returning
a value that can be hold by u16_t.
Signed-off-by: Flavio Ceolin <flavio.ceolin@intel.com>
Everywhere the return of this function was being assigned to u16_t to
save space on stack. Instead of casting in all these places (and may
end up with overflow), just changing this function's return.
Note that the function itself is not checking for overflow yet since
I'm not sure this can happen and/or is a problem. Though now we have
only one single point to fix this problem.

NVS with modified flash layout. At the end of a sector a special ate is
placed that points to the last ate that was written. This special ate
is written when a sector is closed. This allows nvs to travel through
the fs much quicker as it doesn't have to search for the last ate in
a sector.
This modification also speeds up the nvs_init procedure that was very
slow on external (spi) flash.
Remark: As the layout of data in flash is changed old data in the flash
cannot be recovered. It is advised to erase the nvs flash area before
using the changed nvs.
Modification after review by @nvlsianpu applied
Modification after review by @aurel32:
_nvs_prev_ate(): provide a backup search of a valid ate when the sector
close_ate has a bad CRC8. Tested on nrf81522 by making flash writing
bad data to the sector closing ate. Also validated that if a valid ate
is overwritten the filesystem keeps working.
_nvs_gc(): return error if _nvs_flash_cmp_const() is < 0.

Buffer sizes aren't required to be power of 2 for a while. Describe
that by setting buffers sizes to 0, one can get non interrupt driven

Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
Let's have more orthogonal and cleaner API, where buffers are
configured by tty_set_rx_buf/tty_set_tx_buf, and only them. It
means that newly initialized tty starts in unbuffered mode, which
is somewhat a sidestep from a main usecase behind tty, which is
buffered operation, but again, having a cleaner API (and good
docs, explaining users how it should be and what they should do)
prevails.

The whole "tty" concept is conceived around efficient
interrupt-driven operation. However, it's beneficial to add
non interupt-driven operation under the same API:
1. Wider usecase coverage in general.
2. Allows to use the same familiar API (based on POSIX concepts)
even for UART implementations without interrupt support.
3. Allows to switch operation dynamically based on the needs.
For example, if the system is in degraded mode and interrupt
handling cannot be trusted/disabled, allows to still output
diagnostic information to user. This was the original motivation
to provide such a mode, to support logging subsystem's "panic"
mode.
To implement this feature, tty_set_rx_buf() and tty_set_tx_buf()
functions are provided, allowing to reconfigure buffers used
dynamically. If configured buffer length is 0, the operation
switched to unbuffered.

Refactored blocking operation of RTT backend. Log_output buffer
is used directly in case of blocking operation. Detection of
host presence added. Prevent use of RTT lock when in panic mode.
Removed pending on data being read by the host on every message.
Refactor gives savings of 300 bytes in ROM and 120 bytes in RAM.

If burst of log messages was passed to the shell log
backend, it was likely that messages were lost because
shell had no means to control arrivals of log messages.
Added log message enqueueing timeout to the shell instance
to allow blocking logger thread if short-term arrival rate
exceeded shell capabilities.
Added kconfig option for setting log message queue size
and timeout in RTT and UART instances. Added section in
shell documentation which explains interaction between
the logger and shell instance acting as a logger backend.

Commit e4c447aac3 ("usb: add SoF event") added support for calling the
status callback with the USB_DC_SOF value for each SoF when
CONFIG_USB_DEVICE_SOF is enabled. The CDC ACM driver saves the latest
received status and compares it USB_DC_CONFIGURED to decide if it can
send data to the host. This therefore doesn't work any more when the
status callback is called regulary with USB_DC_SOF.
Fix that by ignoring USB_DC_SOF when saving the latest received status.
