This series adds a host-only C reimplementation of NXP's rcw.py for the
pbiformat=2 QorIQ family (LS1028, LS1088, LS2088, LX2160), packaged as
a reusable library (libqoriq-rcw) and a CLI built on top (qoriq-rcw-c).
The library depends on mcpp (a portable C preprocessor that ships as a
reusable libmcpp) for in-process preprocessing of .rcw sources.
Motivation:
- The existing host-qoriq-rcw package wraps NXP's rcw.py reference,
which (a) is slow due to Python startup overhead on every invocation,
(b) requires host Python at build time, and (c) shells out to
gcc -E for preprocessing. The C implementation here uses libmcpp
in-process for hermetic preprocessing and runs ~10x faster on
typical .rcw inputs.
- Beyond the rcw.py reference, qoriq-rcw-c adds two recovery features:
--dump read live RCW from /dev/mem on a running board
--dump-flash recover PBL + PBI from the bootrom slot(s) in
NOR / SD / eMMC
Useful when bringing up a new board or debugging a bad flash.
- The existing host-qoriq-rcw package is untouched. Users who prefer
the rcw.py reference can keep using it; the new package is fully
independent.
Patch breakdown:
1/3 package/mcpp: new package
Matsui CPP, a portable C90/C99/C++98 preprocessor with a
reusable libmcpp. Built host-only with --enable-mcpplib so the
library + public header are available to other host packages.
2/3 package/libqoriq-rcw: new package
Library form of the C reimplementation. host-meson-package,
depends on host-mcpp. Sets -Dtests=false and -Dman=disabled:
the tests/ subdir links libcmocka (only validates library
internals, never executed by Buildroot), and the man-page
step requires pandoc. Both options were added upstream (v1.0.1
for 'tests', v1.0.2 for 'man') specifically to support
distro/Buildroot packaging.
3/3 package/qoriq-rcw-c: new package
CLI on top of libqoriq-rcw. host-meson-package, depends on
host-libqoriq-rcw (transitively pulling in host-mcpp). Also
sets -Dman=disabled; the option landed upstream in v1.0.1.
Naming note: the upstream project is just called "qoriq-rcw"; the "-c"
suffix on the Buildroot package name is purely a disambiguator from
the existing host-qoriq-rcw package (which is the rcw.py wrapper).
The installed binary itself is still named qoriq-rcw.
Tested:
- check-package clean on all files (0 warnings).
- End-to-end build of host-qoriq-rcw-c succeeds against the real
upstream tarballs (mcpp 2.7.2 from SourceForge, libqoriq-rcw 1.0.2
and qoriq-rcw 1.0.1 from GitHub).
- 'qoriq-rcw --help' runs from host/bin/, .rcwi data files install
cleanly under host/share/qoriq-rcw/.
- Fork CI test-pkg matrix (32 toolchains), all green:

mcpp (Matsui CPP) is a portable C/C++ preprocessor, implemented as
both a CLI and a reusable library (libmcpp). It is conformant to
ISO/ANSI C90, C99 and C++98 standards and validated against the
official preprocessor test suite.
This Buildroot package builds a host-only flavour of mcpp with
--enable-mcpplib, so that libmcpp.{a,so} and the public header
mcpp_lib.h are available for other host packages to embed
preprocessor functionality in-process (i.e. without forking a
real cpp binary). The standalone mcpp(1) CLI is installed as
well.

libqoriq-rcw is a C17 reimplementation of NXP's rcw.py for the
pbiformat=2 QorIQ family (LS1028, LS1088, LS2088, LX2160). It compiles
and decompiles RCW (Reset Configuration Word) binaries used by the
SoC bootrom, and exposes the same functionality as a reusable shared
library + pkg-config + public header.
Built as a host-only meson package with -Dtests=false -Dman=disabled.
The upstream tests/ subdir links libcmocka (only validates library
internals -- never executed by Buildroot), and the man-page step
requires pandoc (heavy Haskell-runtime tool typically absent from
packagers' minimal images). The 'tests' option landed upstream in
v1.0.1, the 'man' feature option in v1.0.2; we pin to v1.0.2.
Depends on host-mcpp for in-process C preprocessor support; the
library uses libmcpp instead of shelling out to gcc -E so that the
preprocessing of .rcw sources is hermetic and self-contained.

qoriq-rcw-c is a C reimplementation of NXP's rcw.py CLI for the
pbiformat=2 QorIQ family (LS1028, LS1088, LS2088, LX2160). Built on
top of libqoriq-rcw, it compiles a .rcw source file (preprocessed
in-process via libmcpp) to the binary RCW + PBI image consumed by
the SoC bootrom.
Beyond the rcw.py reference, qoriq-rcw-c adds two recovery features:
--dump read the live RCW from /dev/mem on a running board
(post-PLL-lock RCWSR state; no PBI commands)
--dump-flash recover the PBL preamble + PBI commands from the
bootrom slot(s) in NOR / SD / eMMC
Built as a host-only meson package with -Dman=disabled to skip the
pandoc-based man page (host packages don't install man pages anyway,
and pandoc is a heavy Haskell-runtime build dep). The 'man' feature
option landed upstream in v1.0.1; we pin to v1.0.1.
The "-c" suffix in the Buildroot package name distinguishes the
independent C implementation from the existing host-qoriq-rcw
package, which wraps NXP's rcw.py reference. The upstream project
itself is just "qoriq-rcw"; the suffix is purely a Buildroot-side
disambiguator (the installed binary is still named qoriq-rcw).

Hi Philippe,
Thanks for leading a Buildroot package on this tool.

Right, but it means that the tool has to be compiled and run on the target,
not the host only.

The main benefit (aka faster) to that it avoid pulling/compiling
a full python framework for the host mode, so we get a quick build.

No, those options are not for the host. Moreover, the Config.in does
not need to detail all the runtime options.

Trimmed to a single line in v2:
# skip cmocka-based unit tests and pandoc-generated man page
Also adding a target variant (BR2_PACKAGE_LIBQORIQ_RCW) to satisfy patch
3's target build, which needs libqoriq-rcw at runtime for the --dump /
--dump-flash recovery modes.
Thanks.

Ack. v2 adds BR2_PACKAGE_QORIQ_RCW_C and BR2_PACKAGE_LIBQORIQ_RCW (the
target CLI needs the target library at runtime).

This series adds a C reimplementation of NXP's rcw.py for the
pbiformat=2 QorIQ family (LS1028, LS1088, LS2088, LX2160), packaged
as a reusable library (libqoriq-rcw) and a CLI built on top
(qoriq-rcw-c). Both host and target variants are built. The library
depends on mcpp (a portable C preprocessor with a reusable libmcpp)
for in-process preprocessing of .rcw sources.
Patch breakdown:
1/3 package/mcpp: new package
Matsui CPP + libmcpp. Autotools, host + target. Ships three
Buildroot-side patches for GCC 14/15 compile compatibility
(upstream is dead, last release 2008).
2/3 package/libqoriq-rcw: new package
Library form of the C reimplementation. host-meson + meson,
depends on mcpp. -Dtests=false -Dman=disabled skip the
cmocka and pandoc build-time dependencies.
3/3 package/qoriq-rcw-c: new package
CLI on top of libqoriq-rcw. host-meson + meson, depends on
libqoriq-rcw. -Dman=disabled.
Naming note: upstream project is "qoriq-rcw"; the Buildroot package
name has a "-c" suffix to disambiguate from the existing
host-qoriq-rcw package (which wraps NXP's rcw.py reference). The
installed binary is qoriq-rcw.
Both libqoriq-rcw and qoriq-rcw-c gate on BR2_TOOLCHAIN_GCC_AT_LEAST_8
because upstream declares c_std=c17 in meson.build.
Tested:
- check-package clean on all files (0 warnings).
- Full nbxv3 (LX2160A, aarch64) image cross-build succeeds; the
installed target binaries include qoriq-rcw under /usr/bin/.
- Fork CI test-pkg matrix:
https://gitlab.com/evAdopter/buildroot/-/pipelines/2659083836
Changes v1 -> v2 (addressing Vincent Jardin's on-list review):
patch 1/3 (mcpp):
* added target variant alongside host (Suggested-by: Vincent)
* shortened the --enable-mcpplib inline comment
* added three Buildroot-side patches to fix GCC 14/15 compile
breakage in mcpp's 2008-era C code:
0001 expand: split chained assignment between differently-
typed pointers (-Wincompatible-pointer-types is a hard
error in GCC 14+)
0002 system: request POSIX.1-2008 so readlink() is declared
(mcpp defaults to POSIX.1-1990 which pre-dates it)
0003 system: rename true/false labels reserved in modern C
patch 2/3 (libqoriq-rcw):
* added target variant to satisfy patch 3's target build
* dropped version-history sentence from commit body
* removed consumer-oriented text from Config.in help
* shortened the CONF_OPTS inline comment
* gated on BR2_TOOLCHAIN_GCC_AT_LEAST_8 (c17)
* bumped upstream to v1.0.2 (adds the 'man' meson option)
patch 3/3 (qoriq-rcw-c):
* added target variant per Vincent's request (Suggested-by:) --
the --dump / --dump-flash recovery modes must run on the board
itself
* dropped the --dump / --dump-flash enumeration from Config.in
* reworded the "faster than rcw.py" help text to name the
concrete benefit (avoids pulling in host Python)
* removed the duplicate "-c suffix" comment from .mk
* shortened the pandoc-skip comment
* gated on BR2_TOOLCHAIN_GCC_AT_LEAST_8 (transitive)
* bumped upstream to v1.0.1 (adds the 'man' meson option)

mcpp (Matsui CPP) is a portable C/C++ preprocessor. Builds both
host and target with --enable-mcpplib, so libmcpp.{a,so} and
mcpp_lib.h are available to other packages in addition to the
standalone mcpp(1) CLI.

+ pointers
+
+GCC 14 promotes -Wincompatible-pointer-types from warning to error by
+default. The chained assignment `m_inf->args = m_inf->loc_args = NULL`
+in src/expand.c has different pointer types on each side
+(char * vs LOCATION *) so the assignment fails to build on GCC 14+
+toolchains.
+
+Split the chain into two independent assignments to avoid the
+implicit cross-type conversion.

+Upstream: N/A, mcpp is abandoned upstream (last release 2008).

+Subject: [PATCH] system: request POSIX.1-2008 so readlink() is declared
+
+configed.H defines _POSIX_C_SOURCE=1 (POSIX.1-1990), which pre-dates
+readlink(2) (added in POSIX.1-2001). Modern glibc treats readlink()
+as guarded by _POSIX_C_SOURCE >= 200112L; with only 1 requested, the
+declaration is invisible, and GCC 15+ turns the resulting
+implicit-declaration into a hard error.
+
+Bump the requested POSIX level to 200809L (POSIX.1-2008) at the top
+of system.c, before any header inclusion. Doing it in this one
+translation unit keeps the change tightly scoped to the file that
+needs readlink(); other .c files continue to see mcpp's default.
+
+Upstream: N/A, mcpp is abandoned upstream (last release 2008).

+Subject: [PATCH] system: rename true/false labels (reserved in modern C)
+
+open_file() uses `true:` and `false:` as C label names for goto
+targets. Since C99, <stdbool.h> defines `true` and `false` as macros
+expanding to 1 and 0; in C23 they are outright keywords. Either way,
+using them as identifiers (labels here) is a syntax error on modern
+GCC (>= 14 / 15).
+
+Rename the two labels to `open_success:` and `open_failure:` (with
+the matching goto sites) so the code parses under both classic and
+C23-oriented compilers.

libqoriq-rcw is a C17 reimplementation of NXP's rcw.py, packaged
as a reusable shared library + pkg-config + public header. It
compiles and decompiles RCW (Reset Configuration Word) binaries
for the pbiformat=2 QorIQ family (LS1028, LS1088, LS2088, LX2160).
Both host and target variants are built. The library uses libmcpp
in-process instead of shelling out to gcc -E, so preprocessing is
hermetic. Built with -Dtests=false (skip cmocka unit tests) and
-Dman=disabled (skip pandoc-generated man page).

qoriq-rcw-c is a C reimplementation of NXP's rcw.py CLI for the
pbiformat=2 QorIQ family (LS1028, LS1088, LS2088, LX2160). Both
host and target variants are built: the target variant provides
recovery modes (--dump / --dump-flash) that need to run on the
board itself.
The "-c" suffix distinguishes this from the existing host-qoriq-rcw
package which wraps NXP's rcw.py reference; the installed binary
is qoriq-rcw.
