[PATCHv2 0/3] mpc52xx/wdt: re-enable the MPC5200 WDT

[Albrecht Dreß]

This set of patches merges the MPC5200 WDT into the GPT code, making it
functional again - currently, the MPC5200 GPT code blocks using the WDT.

Additionally, it defines a new OF property as to reserve and/or enable the
WDT during the boot process which may be a requirement for safety-related
(e.g. ISO/EN 61508) applications.

Note that all patches are against Grant Likely's "next" tree.

Compared to the first version of the patch, the basic change is a full merge
of the WDT code into the GPT implementation in arch/powerpc/platforms/52xx.
It makes the old WDT implementation file obsolete.  As a side effect, it is
not possible any more to build the 52xx WDT support as module which shouldn't
be a big issue, though.

Cheers, Albrecht.
