This commit fixes code generation for loading halfwords using an offset
greater than 255.
The old code blindly encoded the offset into a `LDRH Rd, [Rn, #imm]`
opcode, but only the lowest 8 bits would be put into the opcode itself.
This commit instead generates a two-opcodes sequence, a constant load into
R8, and then `LDRH Rd, [Rn, R8]`.
This fixes `tests/extmod/vfs_rom.py` for the qemu/SABRELITE board.

This commit fixes code generation for loading a local's address if its
index is greater than 63.
The old code blindly encoded the offset into an `ADD Rd, Rn, #imm` opcode,

This commit increases the GC heap size from 120KiB to 140KiB, as it is
needed to make the full test suite pass on SABRELITE when ran through the
armv6 native emitter.
This is needed as the code output by the armv6 native emitter is limited to
4-bytes opcodes and thus takes more space than other ARM emitters.
To keep things aligned, the RV32 port also got its heap size increased even
though it is not needed on that platform right now.

The Micro:Bit machine definition in Qemu has soft MMU support enabled,
which is currently not compatible with the way MicroPython generates code
that needs to call back into non-emitted code.
As a stop-gap solution, the native code emitter for the MICROBIT board is
turned off.

When a CPU exception is raised when emulating a Thumb-capable processor,
the default exception handler would simply enter in an endless loop without
providing any further information.
This commit adds a more complete exception handler that dumps to STDOUT the
exception cause and the status of the registers at the moment of the
exception.

Some PTY targets, namely `NETDUINO2` and `MICROBIT` under Qemu, take a bit
more time to present a REPL than usual. The pyboard tool is a bit too
impatient and would bail out before any of those targets had a chance to
respond to the raw REPL request.

This entry was originally used to override the firmware filenames generated
by the build server, but these days all filenames should match the board
directory name. So, remove the "id" entry and let the default be used.
This is a follow-up to 1a99f74063 (these
three boards were added after that change).

This commit fixes a test failure for `extmod/re_sub.py` where the code,
whilst being correct, would not make the test pass due to a newer
Python version than expected.
On Python 3.13, running `tests/extmod/re_sub.py` would yield a
deprecation warning about `re.sub` not providing the match count as a
keyword parameter. This warning would be embedded in the expected test
result and thus the test would always fail.

The `asmbcc`, `asmbitops`, `asmconst` and `asmit` tests fail to compile

When using unittest (for example) with injected mpy files, not only does
the name of the main test module need to be `__main__`, but also the
`__main__` module should correspond to this injected module. Otherwise the

Adds a configurable version string to a known location at the end of mboot

A board can override the defaults, or disable the version string entirely
by setting MBOOT_VERSION_ALLOCATED_BYTES=0.

This commit implements a method to detect at runtime if inline assembler
support is enabled, and if so which platform it targets.
This allows clean test runs even on modified version of ARM-based ports
where inline assembler support is disabled, running inline assembler tests
on ports that have such feature not enabled by default and manually
enabled, and allows to always run the correct inlineasm tests for ports
that support more than one architecture (esp32, qemu, rp2).

In certain circumstances depending on the code size, the
`deflate_decompress` test fails on both ARM and RV32 with a memory
allocation failure error. The issue is mitigated by having a larger GC
heap, in this case around 20 KBytes more than the original 100 KBytes
default.
This commit makes the GC heap size configurable on a per-arch basis, with
both ARM and RV32 using the enlarged 120 KBytes heap.

This commit adds support for writing inline assembler functions when
targeting a RV32IMC processor.
Given that this takes up a bit of rodata space due to its large
instruction decoding table and its extensive error messages, it is

qemu port.

This makes the existing popcount(uint32_t) implementation found in the

case.

If the file can be memory mapped (because it responds to the buffer

This commit defines a new ROMFS filesystem for storing read-only files that
can be memory mapped, and a new VfsRom driver. Files opened from this
filesystem support the buffer protocol. This allows naturally getting the
memory-mapped address of the file using:
- memoryview(file)
- uctypes.addressof(file)
Furthermore, if these files are .mpy files then their content can be
referenced in-place when importing. Such imports take up a lot less RAM
than importing from a normal filesystem. This is essentially dynamically
frozen .mpy files, building on the revamped v6 .mpy file format.
