[v2 summary: zero inter-commit build errors on all power, arm,
and mips boards (which means some patches got merged into patch #1),
checkpatch fixes, and postponement of the libfdt changes, primarily
to get the bulk of these in during this merge window]
This 25-patch series only begins to address making u-boot source more
'sparseable,' or sparse-clean, ultimately to catch type, address space,
and endianness mismatches and generally improve code quality. E.g.,
a couple of endianness bugs are found in of_bus_default_translate()
and fdt_get_base_address() (not includeded in this v2 series - fixes
pending libfdt patch for dtc).
Patch 1 adds endianness attributes to byteorder.h helpers, e.g.,
cpu_to_be32(). This is required for correct operation and prevents
sparse from emitting false-positives. It comes with the side effect
of breaking many builds, because u-boot has various places where
attributes were being defined differently, so it includes fixes for those.
Patches 2-5 fix issues where u-boot had imported linux header code
and the importer simply force-#defined sparse-specific attributes to
nothing, to allow u-boot to build without redefined warnings.
Patches 6-7 are general sparse fixes to common powerpc areas.
Patches 8-10 are general sparse fixes to common header areas (e.g.,
patch 8 changes the long-standing u-boot image header types to __be32,
as per u-boot image definition).
Patches 11-12 addresses sparse fixes for the net subsystem.
Patches 13-14 do the same for lib/.
Patches 15-17 for Power Arch's mpc8xxx, 83xx, and 85xx subsystems.
Last but not least, patches 18-25 attempt to clean up various drivers.
Note that the two libfdt patches present in series one are omitted here
for u-boot merge window, they will be resubmitted after dtc have merged
a libfdt-dependent patch.
For authors of new patches not willing to sift through the still quite
large sparse output for their board/platform, though interested in what
sparse has to say about their new code, it is recommended to build
with make C=1 after changes such that sparse output will only include
newly built code.
fyi, I've pushed the series onto the u-boot-mpc83xx tree,
'sparsefixes' branch:
http://git.denx.de/u-boot.git/?p=u-boot/u-boot-mpc83xx.git;a=shortlog;h=refs/heads/sparsefixes
All power, arm, mips boards tested.
Thanks,
Kim
