[U-Boot] [PATCH v3 0/5] consolidate hang()

[Andreas Bießmann]

This series started with intention to make a hung board visualize the
(end-)user that it does hang(). The first approach was to make all the
different hang() functions weak and provide board specific versions to
implement the 'visualization' there.
After some discussion it turned out, that there is still an interface to
visualize such states to the user: the 'bootstage' stuff.

BTW:
This is my first try sending a series with patman. All I can say is:
patman is really cool ;)

The 'microblaze: fix style in board.c' is an leftover from the first approach.

The 'nios2: fix style in board.c' is an leftover from the first approach.

The 'lib: consolidate hang()' is build tested on arm and avr32. It may
produces errors on other arches like ppc cause the previous SPL inlined hang()
function was also removed.  We need to discuss if we always pull in the
libgeneric unconditional into SPL or provide a second hang() for those boards
which do not link against libgeneric in SPL.

Since v2 got a complete (compile-)test on powerpc by Wolfgang I think we can
stick with the current solution.  v3 includes some minor changes mentioned in
the changelog of respective patches.

Changes in v3:
 * shorten error string for 'no FDT'
 * remove unnecessarily added linux/compiler.h
 * fix typo in new hang() docu
 * use simplified macro for SPL_LIBCOMMON_SUPPORT as suggested by Benoît

Changes in v2:
 * delete all hang() and provide generic lib/hang.c
