Hei hei, while working on FPGA support for a new device I discovered debug logging in some FPGA drivers is still done as in the old days. Bring that to what I thougt would be the currently preferred approach.
Notes: Adding those Kconfig symbols in patch 1 is just to be able to build two of the old drivers. All drivers touched were build tested with sandbox_defconfig and GCC 8 on Debian GNU/Linux 10 (buster). Lines with other possibly questionable output were not touched, only what seemed to be designated debug output, and only for FPGA drivers having that ancient FPGA_DEBUG / PRINTF macros, so there's room for future improvements. Changelog: v3 -> v4: - Reordered patches, Kconfig patch comes first now (made it easier to build and test the series step by step) - Added three patches fixing printf compiler warnings first, before changing to the new logging framework (so CI should not fail anymore with -Werror) v2 -> v3: - Patch introducing FPGA uclass was completely reworked, sent independently from this series, and applied already, thus removed - Because requiring that new FPGA uclass changes, rebased on Michal's microblaze branch '20221005' - Removed '"%s …", __func__' and '"%d …", __line__' from log messages, because log framework can add those (enabled by CONFIG_LOGF_FUNC and CONFIG_LOGF_LINE) v1 -> v2: - Rebased on master - Added patch to introduce new FPGA uclass in front of the other patches - Use that new uclass as log category - Slightly reworded cover letter Greets Alex Cc: Michal Simek <michal.si...@amd.com> Alexander Dahl (10): fpga: Add missing Kconfig symbols for old FPGA drivers fpga: spartan2: Fix printf arguments warning fpga: spartan3: Fix printf arguments warning fpga: virtex2: Fix printf format string warnings fpga: altera: Use logging feature instead of FPGA_DEBUG fpga: cyclon2: Use logging feature instead of FPGA_DEBUG fpga: ACEX1K: Use logging feature instead of FPGA_DEBUG fpga: spartan2: Use logging feature instead of FPGA_DEBUG fpga: spartan3: Use logging feature instead of FPGA_DEBUG fpga: virtex2: Use logging feature instead of FPGA_DEBUG drivers/fpga/ACEX1K.c | 37 +++++++++---------- drivers/fpga/Kconfig | 12 +++++++ drivers/fpga/altera.c | 11 +++--- drivers/fpga/cyclon2.c | 38 +++++++++----------- drivers/fpga/spartan2.c | 80 +++++++++++++++++++---------------------- drivers/fpga/spartan3.c | 80 +++++++++++++++++++---------------------- drivers/fpga/virtex2.c | 69 ++++++++++++++++------------------- 7 files changed, 152 insertions(+), 175 deletions(-) base-commit: 2d8cf392a77815f062446ef441f1078958dc1b2a -- 2.30.2
