* Build boot_stage2 with Bazel Introduces the initial foundations of a Bazel build, including a toolchain, critical generated headers, platform patterns, and enough BUILD files to build boot_stage2. * Bazel libraries to support picotool * Move SDK defines to toolchain * Switch to `archive_override` in MODULE.bazel Uses archive_override where applicable to allow transitive bzlmod deps to propagate. * Multiplatform objcopy selection in Bazel build Makes an objcopy alias that redirects to the objcopy tool for the current exec platform, which allows boot_stage2 to build on Linux, macOS, and Windows. * Generate Bazel build files Adds initial set of generated Bazel build files. Note that these do not yet build, as dependency cycles are present. * Fix dependency cycles in Bazel build Fixes many dependency cycles, some were unintentionally created by the build file generator, others are true dependency cycles that require manual workarounds. * Silence warning in pico_stdio Bazel build Silences a stray warning in the Bazel build. * Fix wildcard Bazel build This makes `bazel build //...` succeed, and also prevents the fetching of toolchains that aren't compatible with the current execution environment (i.e. Windows computers will no longer try to download macOS toolchains). * Get the SDK working Finishes out the remainder of the work required to successfully compile a working blinky example. * Fix UART stdio dependencies in Bazel build Fixes some dependencies around pico_stdlib so that pico_stdlib links properly and UART stdio works. * Add linux support to Bazel build * Get Bazel deps from registry Adds external an external registry for resolving Bazel module dependencies. * Fix host configuration for picotool Provides the appropriate defines for host builds to support the picotool build. * Remove -ffreestanding from Bazel toolchain The -ffreestanding toolchain flag is quite strict, so remove it from the Bazel toolchain. * Remove unused .bzl file * Reduce Bazel compiler flags Cuts out most of the Bazel toolchain flags and only specifies the bare-minimum set of flags. Also, adds wrapper linker flags for functions the SDK wraps. * Get USB serial working Adds initial TinyUSB support and enough integration to get USB serial working. * Remove "Generated build file" Removes comments that indicates BUILD.bazel files are generated. This was used during initial bringup to indicate hand-crafted vs automatically generated BUILD.bazel files. * Do not build USB libraries unless configured Prevents USB libraries from being built unless the build is properly configured to use them. * Switch to rules_cc toolchains Moves toolchain configuration to use the new rules in rules_cc. * Minor cleanup in parse_version.py Cleans up trailing whitespace and runs the black formatter on parse_version.py. * Simplify constraint dimensions in Bazel build Consolidates the class/chip constraint settings to be a single constraint_setting with a config_setting that represents the rp2 class. * Update pin of rules_cc in Bazel build Includes a necessary fix for the target_compatible_with expression in the cc_toolchain to work as intended. * Move toolchains from pico.bzl to BUILD.bazel Moves toolchain definitions from pico.bzl to BUILD.bazel to make them easier to find and read. * Run buildifier on Bazel build files Fix trivial formatting issues by running buildifier on all BUILD.bazel files. * Make objcopy rule Makes a simple objcopy rule to remove direct references to the ARM toolchains. * Fix link flags in Bazel build Critical flags were not being applied to link steps. This applies -mcpu and -mthumb to the link steps to make the produced binaries work again. * Mention missing host build support * Fix various Bazel library rules * pico_bit_ops was incomplete. * pico_double and pico_float were trying to link in the "none" implementation. * Extend Bazel build documentation Improves documentation and comments across the Bazel build. * Clean up auxilary tools in Bazel build Switches genrules to use skylib rules to simplify things. Reworks version header generation to use the Bazel module version rather than parsing CMake. * Update boot_stage2 Bazel build file Moves `includes` to be enumerated on the correct library. * Add WORKSPACE version fallback WORKSPACE Bazel projects don't support querying module version, so add a fallback of '0.0.1-WORKSPACE' so the build can succeed. * Fix malloc handling in Bazel build * Fix Bazel dependency cycle in pico_malloc * Prevent malloc from being linked into boot_stage2 Prevents Bazel from ever trying to link malloc into the boot_stage2 binary. * Remove custom bootloader platform A dedicated boot_stage2 platform introduces a lot of complexity that needs to be more thought-through.
