This series allows the user to replace the default kernel boot logo by a custom one directly in the kernel configuration. This makes it easier to customise the boot logo without the need to modify the sources and allows such customisation to remain persistent after applying the configuration to another version of the kernel.
Patch #1 and #2 are clean-up and preparation while patch #3 is the main feature of this series: making the boot logo customisable. While working on this, I realised that managing the logo file directly in Kbuild allows us to simplify how we handle the different existing variants of the Tux logo. This series thus ends with a clean-up which moves all the logo selection logic to Kbuild except from one special case (details in the patch description), simplifying the Makefile and the C code. Patch #4 and #5 do a tree-wide clean-up on the Kconfig symbols that are to be removed in patch #7. Patch #6 removes the Macintosh 68k logo which is conflicting with our simplification plans. Patch #7 finally simplifies the logic as explained above. Signed-off-by: Vincent Mailhol <[email protected]> --- Changes in v3: - v2 broke the logo selection for m68k resulting in the MAC logo replacing the default logo on some machine where it shouldn't. v3 resolves the conflict by removing that logo. - Typo fix in patch #4 description. Link to v2: https://lore.kernel.org/r/[email protected] Changes in v2: - By removing the logo_spe_clut224.o target from the Makefile, v1 also removed the logo_spe_clut224 object which is still being referenced in arch/powerpc/platforms/cell/spu_base.c Restore the logo_spe_clut224.o target.
