The default I2C init does not require setting SCL or SDA but the default
I2C0 pins for C3, S3 conflict with the espressif GPIO usage.

For the C3, pins 18/19 are for USB/JTAG.  If used for I2C() they will cause
the REPL to hang on initialization of the I2C.

For the S3 pin 19 is allocated for USB/JTAG also but the defaults do not
seem to affect the REPL.

This commit lets the Viper code generator use optimised code sequences
for register-indexed load and store operations when generating Arm code.

The existing code defaulted to generic multi-operations code sequences
for Arm code on most cases.  Now optimised implementations are provided
for register-indexed loads and stores of all data sizes, taking at most
two machine opcodes for each operation.

This commit lets the Viper code generator use optimised code sequence
for register-indexed load and store operations when generating Thumb
code.

Register-indexed load and store operations for Thumb now can take at
most two machine opcodes for halfword and word values, and just a single
machine opcode for byte values.  The original implementation could
generate up to four opcodes in the worst case (dealing with word
values).

This commit cleans up the Viper code generation blocks for
register-indexed load and store operations.

An attempt is made to simplify the code in the common code generator
code block, by moving architecture-specific code to the appropriate
native generation backends whenever possible.  This should make that
specific bit of code in the Viper generator clearer and easier to
maintain in the long term.

To achieve this, six generic assembler meta-opcodes have been
introduced, named `ASM_{LOAD,STORE}{8,16,32}_REG_REG_REG`.  A
platform-independent implementation for those operations is provided, so
backends that cannot emit a shorter sequence for the requested operation
or are fine with the platform-independent implementation can just not
provide said meta-opcodes.

This commit adds a series of test cases to exercise the Viper code
generator load/store emitting capabilities on certain boundary
conditions.

The new test cases check whether the emitted load/store code performs
correctly when dealing with specific memory offsets, which trigger
specific code generation sequences on different architectures.

Right now the cases are for unsigned offsets whose bitmasks span up to
5, 8, and 12 bits (respectively Arm/Thumb, Xtensa, RV32).

This commit lets the Thumb native emitter generate a proper opcode
sequence when calculating an indexed register offset for load/store
operations with said offset beight both greater than 65535 and not
able to be represented as a shifted 8-bit bitmask.

The original code would assume the scaled index would always fit in 16
bits and silently discard upper bits of the offset.  Now an optimised
constant loading sequence is emitted instead, and the final offset is
also stored in the correct register in all cases.

Signed-off-by: Alessandro Gatti <[email protected]>

This commit performs some minor clean up for the code involved in Viper
load/store operations when said operations have an integer index.

Most platform-specific code blocks were able to generate correct opcodes
even when the index is 0, but they would still fall back to the general
case.  The general case would still emit a shortened opcode sequence so
this commit does not alter the overall behaviour, but makes it easier to
extend platform-specific code whenever the full index range is going to
be handled rather than a subset of indices as it is now.

On nRF52, the physical SRAM is mapped to 0x20000000 for data access and
0x00800000 for instruction access.  So, while native code is allocated and
written using addresses in the 0x20000000 range, it must execute from the
0x00800000 range.

This commit makes this work correctly on nRF52 MCUs by adjusting the

This commit adds an `attached_to_repl` property to each UART, and makes
sure that property is correctly set/unset when the UART is attached to or
detached from the REPL.

That property is then used to make sure incoming characters on the UART are
only checked for the interrupt character if the UART is attached to the
REPL.  Otherwise a board without REPL on UART can have its code interrupted
if ctrl-C is received on the UART.

Also, put incoming UART characters on to `stdin_ringbuf` instead of the
UARTs ring buffer (the former is much larger than the latter).

- WiFi and BLE via cyw43-driver (SDIO backend)

Note that the N6 does not have internal flash, and has some tricky boot

This is code makes sure that time functions work properly on a
reasonable date range, on all platforms, regardless of the epoch.
The suggested minimum range is 1970 to 2099.

In order to reduce code footprint, code to support far away dates
is only enabled specified by the port.

New types are defined to identify timestamps.

The implementation with the smallest code footprint is when
support timerange is limited to 1970-2099 and Epoch is 1970.
This makes it possible to use 32 bit unsigned integers for
all timestamps.

On ARM4F, adding support for dates up to year 3000 adds
460 bytes of code. Supporting dates back to 1600 adds
