Always write the path as "abosolute" (relative to the root of pico-sdk) as that makes searching for it (when building the RP2040 datasheet) much faster. This matches the behaviour of extract_build_defines.py and extract_cmake_configs.py
* Small whitespace fixup
* typo bugfix
* Small refactoring of check_board_header.py
* Make structure of rp2040_interface_pins.json more explicit, so that it can be more easily extended
* Move definition of valid-pins from python to json
* Check that each interface includes all (minimally) expected pins
Note that UART_CTS, UART_RTS & SPI_CSN are classed as optional
* Split "expected_functions" into "required" (all of these pins must be present) and "one_of" (at least one of these pins must be present)
* Add script to automatically validate board header files
* Fix small automatically-found inconsistencies in various board header files
* Tweak and add board header file from abandoned PR #1174
* Add host Bazel build
Updates target_compatible_with across the repo to ensure that wildcard
builds for both host and rp2040 succeed.
* Get unit tests building
* Add Python script to identify build system differences
Uses the build system tags to make it easier to identify differences
between the CMake and Bazel builds.
* Temporarily disable pico divider test
* Support PICO_BARE_METAL in Bazel
* Support PICO_NO_GC_SECTIONS in Bazel
* Support boot2 configuration in Bazel
Adds support for PICO_DEFAULT_BOOT_STAGE2 and
PICO_DEFAULT_BOOT_STAGE2_FILE in the Bazel build.
* Allowlist some CMake-only options
* Support CXX configuration options in Bazel
* Move multiple_choice_flag.bzl
* Support all pico boards
* Support linking multiple stdio implementations
Changes the Bazel build so stdio implementations are no longer mutually
exclusive.
* Add PICO_BOOT_STAGE2_LINK_IMAGE
* Support PICO_CMSIS_PATH in Bazel
* Support PICO_USE_DEFAULT_MAX_PAGE_SIZE in Bazel
* Silence PICO_CMSIS_VENDOR and PICO_CMSIS_DEVICE differences
* Support PICO_STDIO_USB_CONNECT_WAIT_TIMEOUT_MS in Bazel
* Properly support version defines
* Support embedding binary info in Bazel
* Embed build type in binary
* Support different linker scripts in Bazel build
* Finish out missing PICO_BUILD_DEFINE in Bazel build
* Support PICO_NO_TARGET_NAME
* Reorganize initial configuration options in Bazel
Cleans up and reorganizes some of the initial configuration options
added to the Bazel build so everything is consistent.
* Add builds for pioasm and elf2uf2
* Use Python rules from rules_python
* Actually link in output formats in pioasm tool
* Make tools have public visibility
* Add UF2 Bazel aspect
* Add TODOs for pioasm/uf2 helpers
* Fix compile flag typo
* Update Bazel SDK configuration strings to match recent CMake changes
* Fix pico_divider test
* Clean up straggling TODOs
* Clarify pico_stdio_test compatibility
* Initial Bazel Pico W support
* Add new files from develop
* Clean up compatibility expressions in Bazel build
* Clean up rp2 constraint handling in Bazel
* More Bazel docs cleanup
* Format Bazel build files
* Consolidate transitions in the Pico SDK
* Make every _allowlist_function_transition explicit
* More docs cleanup
* Add a few missing defines
* Improve PICO_CONFIG_HEADER correctness in Bazel
* Minor docs clarifications
* Add ...3.27 to the cmake_minimum_required, and make minimum 3.13 everywhere

Running a build with a newer CMake version results in a deprecation
warning from the tools subdirectory
[13/108] Performing configure step for 'PioasmBuild'
loading initial cache file /.../build/pico-sdk/src/rp2_common/pico_cyw43_driver/pioasm/tmp/PioasmBuild-cache-Release.cmake
CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
Compatibility with CMake < 3.5 will be removed from a future version of
CMake.
Update the VERSION argument <min> value or use a ...<max> suffix to tell
CMake that the project does not need compatibility with older versions.
Raise the minimum version requirement for the tools to the same version
that is required in the top-level CMakeLists.txt anyway.
* Fix various non-GCC warnings (no effect on GCC)
* Reduce use of typeof since non GCC compilers may not support it
* Introduce PICO_C_COMPILER_IS_GNU, PICO_C_COMPILER_IS_CLANG, PICO_C_COMPILER_IS_IAR to CMake as if (CMAKE_C_COMPILER_ID STREQUAL "xxx") is a bit verbose
* Use "unified_asm" macro for all inline asm (it is "volatile __asm" on GNU with a .syntex unified)
* Use NOLOAD instead of COPY in linker scripts (arguably more correct anyway)
* Use the same style for setting _etext in all 4 linker scripts (to the beginning of .data). Clang aligns .data on a 16 byte boundary. Note ideally we'd
add a new symbol __data_source, however that would break backwards compatibility with existing user linker scripts
* Use "a" for .stack, .heap sections because clang complains otherwise, and they are explicitly NOLOAD anyway
* Avoid duplicating __sev, __wfe, __wfi which Clang sometimes seems to provide as built-ins
* Add missing kitchen_sink_blocked_ram binary
* Allow build with LLVM Embedded Toolchain Form ARM v 14.0.0 (unsupported atm)
* Added ARCHIVE_OUTPUT_DIRECTORY to uf2 output in CMake
This Commit enables the use of the ARCHIVE_OUTPUT_DIRECTORY target
properties in CMake for the generation of uf2 files.
The changeset in lines 47..51 is necessary due to CMake not
automatically creating the ARCHIVE_OUTPUT_DIRECTORY if no archive target
is present.
* rework cmake changes to make it friendler for non absolute paths

While working on the [online pioasm](https://wokwi.com/tools/pioasm), I found several PIO instructions that result in invalid python code. Here is a small program that demonstrate the issue:
```
.program python_issue
push block
wait 0 irq 1 rel
irq clear 1 rel
```
And the resulting Python program:
```python
# -------------------------------------------------- #
# This file is autogenerated by pioasm; do not edit! #
# -------------------------------------------------- #
import rp2
from machine import Pin
# ----------- #
# python_test #
# ----------- #
@rp2.asm_pio()
def python_test():
wrap_target()
push(, block) # 0
wait(0, irq, 1 rel) # 1
irq(clear 1 rel) # 2
wrap()
```
After this fix, the above program compiles to a valid python syntax:
```python
# -------------------------------------------------- #
# This file is autogenerated by pioasm; do not edit! #
# -------------------------------------------------- #
import rp2
from machine import Pin
# ----------- #
# python_test #
# ----------- #
@rp2.asm_pio()
def python_test():
wrap_target()
push(block) # 0
wait(0, irq, rel(1)) # 1
irq(clear, rel(1)) # 2
wrap()
```
