[U-Boot] [PATCH 00/32] Initial sparse fix series

This 32-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., in this
initial dose whose main purpose is to reduce the output volume to workable
levels, a couple of endianness bugs are found and fixed in
of_bus_default_translate() and fdt_get_base_address(). See [PATCH 14/32]
common/fdt_support.c: sparse fixes.
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.
Patches 2-6 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.
Patches 7-10 are general sparse fixes to common header areas.
Patch 11 is too, which also changes the long-standing u-boot image header
types to __be32, as per u-boot image definition.
Patches 12-14 address further misc. sparse issues in common/.
Patches 15-16 do the same for the net subsystem.
Patches 17-18 do the same for lib/.
Patch 19 for include/fdt.h.
Patches 20-23 for Power Arch's mpc8xxx, 83xx, and 85xx subsystems.
Last but not least, patches 24-32 attempt to clean up various drivers.
Note that there are two libfdt dependencies:
1. commits aa28b89b "libfdt: Add helpers for 64-bit integer properties" and
commit 786ed04 "libfdt: Add support for appending the values to a existing
property", currently sitting in u-boot-fdt/next. This series is based
on today's mainline u-boot/next with those two patches pre-applied.
2. potential upstream dtc change dependencies, due to having to attribute base
device tree header types to __be32 in include/libfdt. See patch 19/32
"include/fdt.h: sparse fixes". It is unknown whether such changes would
be welcome to dtc (but there's a way to find out :).
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.
For your convenience, I've pushed the series onto the u-boot-mpc83xx
tree, 'sparsefixes' branch [1]. The branch includes libfdt dependency
#1 mentioned above.
Build-tested in both endians :). Please help test.
Thanks,
Kim
