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