Building a minimal userland (busybox, openssl, nginx,\ndropbear, ntp) on top of uClibc-ng exposed the fixes gathered in this\nseries.\n\nThe series can be grouped as follows:\n\n * Arch and global flags\n - arch/Config.in.m68k: new BR2_m68k_cf5441x subarch entry\n - package/gcc: force --with-arch=cf on MCF5441x so internal\n multilibs are driven by the ColdFire ISA, not m68k-classic\n - package/Makefile.in: add ColdFire workaround flags (mxgot, etc.)\n consumed by multiple packages\n\n * Toolchain companions\n - package/gdb: use static libgcc on ColdFire to avoid runtime\n libgcc_s ABI mismatch\n - package/gmp: disable C++ bindings on ColdFire (libstdc++ is not\n available on this target flavour)\n\n * Network stack\n - package/libopenssl: extend ColdFire handling (OPENSSL_NO_ATOMICS,\n OPENSSL_NO_ASM, OPENSSL_SMALL_FOOTPRINT, mxgot)\n - package/dropbear: disable ML-KEM768 which triggers an ICE in gcc\n 14 on m68k\n - package/ntp: link libatomic when the toolchain provides it, so\n 64 bit atomics resolve at link time\n - package/nginx: propagate ColdFire TLS/atomic settings\n\n * Misc\n - package/mawk: create the awk symlink on install so scripts relying\n on /usr/bin/awk keep working\n - package/libglib2: add ColdFire conditional tweaks needed for the\n target build\n\nThe series has been validated on real hardware (Freescale/NXP MCF54418\nbased ColdFire V4e board, 250 MHz, 256 MiB DDR, uClibc-ng) via a\nbuildroot initramfs image: kernel boot, openssl, nginx, dropbear and\nntpd all start cleanly with the compiled flags visible in\n\"openssl version -a\" (mxgot, OPENSSL_NO_ATOMICS, OPENSSL_NO_ASM).\n\nThe series applies cleanly on top of current master. No regressions\nexpected on other m68k variants (mcf5208, q800) or other arches; the\nchanges are all guarded by BR2_m68k_cf or MCF5441x conditionals.\n\nThanks for the review.\n\nJean-Michel Hautbois (11):\n arch/Config.in.m68k: add ColdFire MCF5441x support\n package/gcc: force --with-arch=cf on m68k MCF5441x\n package/Makefile.in: add global ColdFire workaround flags\n package/gmp: disable C++ bindings on m68k ColdFire\n package/gdb: use static libgcc on m68k ColdFire\n package/libopenssl: extend m68k ColdFire support\n package/dropbear: disable ML-KEM768 on m68k\n package/ntp: Link libatomic when available\n package/nginx: add m68k ColdFire TLS support\n package/mawk: create awk symlink on install\n package/libglib2: add m68k ColdFire support\n\n arch/Config.in.m68k | 7 +++++++\n package/Makefile.in | 4 ++++\n package/dropbear/dropbear.mk | 7 +++++++\n package/gcc/gcc.mk | 4 ++++\n package/gdb/gdb.mk | 5 +++++\n package/gmp/gmp.mk | 4 +++-\n package/libglib2/libglib2.mk | 11 ++++++++++-\n package/libopenssl/libopenssl.mk | 3 +++\n package/mawk/mawk.mk | 6 ++++++\n package/nginx/nginx.mk | 6 ++++++\n package/ntp/ntp.mk | 5 +++++\n 11 files changed, 60 insertions(+), 2 deletions(-)" }
