453f98914e zephyr/main: Don't unconditionally dump stats on each GC. 
This was a debug output for initial porting, breaks tests.

40e72e4a5c zephyr: Make sure that correct Zephyr config is used for "minimal" build. 
Overriding CONF_FILE in "minimal" target itself is too late due to include-
pinned $(Z_EXPORTS) target.

5298472fee zephyr: Enable SLIP networking for the default build. 
This makes MicroPython app running in QEMU be pingable from the host (by
following QEMU networking setup instructions,
https://www.zephyrproject.org/doc/samples/net/qemu_setup.html).

56a514c193 zephyr/uart_core: Access console UART directly instead of printk() hack. 
This is required to avoid extra level of output "cooking" ("\r\r\n") and
make test infrastructure work. On the other hand, this breaks somewhat
Zephyr console abstraction.

1779a62085 zephyr: Switch to Zephyr 1.6 unified kernel API. 
In 1.6, Zephyr switched to "unified kernel" and new API set. Older kernel
API is supported, but marked as deprecated and leads to warnings.

3ccdbf792c zephyr/Makefile: Add -fomit-frame-pointer. 
Somehow, Zephyr uses -fno-omit-frame-pointer, whch bloats code size
considerably (+5K for minimal ARM Thumb2 build).

uart_irq_input_hook_set() was renamed to uart_console_in_debug_hook_install()
and accepts different params.

67b6d9d499 zephyr: Initial implementation of machine.Pin. 
The integration with Zephyr is fairly clean but as MicroPython Hardware API
requires pin ID to be a single value, but Zephyr operates GPIO in terms of
ports and pins, not just pins, a "hierarchical" ID is required, using tuple
of (port, pin). Port is a string, effectively a device name of a GPIO port,
per Zephyr conventions these are "GPIO_0", "GPIO_1", etc.; pin is integer
number of pin with the port (supposed to be in range 0-31).

Example of pin initialization:

pin = Pin(("GPIO_1", 21), Pin.OUT)

(an LED on FRDM-K64F's Port B, Pin 21).

There is support for in/out pins and pull up/pull down but currently
there is no interrupt support.

a3519332b6 zephyr: Use board/SoC values for startup banner based on Zephyr config. 
This patch modifies the HW macro definition in order to let micropython
report correctly the BOARD and the SOC on which it is working on.

3cdccb9b14 zephyr: Fix mp_hal_set_interrupt_char() declaration to be compatible. 
With other ports. Other ports declare it in mphalport.h, it can be
inline or macro.

479b961d39 zephyr: Implement utime module. 
This provides time and sleep together with the usual ticks_us/_ms/_diff
and sleep_us/ms family.

We also provide access to Zephyr's high precision timer as ticks_cpu().

b6a544b917 zephyr: Implement the help() function. 
The boot issue text mentions a help() function and encourages
the user to run it. It is very disconcerting to find that the
function does not exist...

5a699a7017 zephyr: Use recently added "make outputexports" Zephyr target. 
The outputexpors target, which exports Zephyr environment variables, was
recently added to Zephyr. By exploiting this feature we can hugely simplify
the build system, improving robustness at the same time.
