Subject: [PATCH] powerpc: Allow for ppc_md restart, power_off, and halt to be NULL
Date: Fri, 13 Jan 2006 10:15:17 -0600 (CST) [thread overview]
Message-ID: <Pine.LNX.4.44.0601131014350.18314-100000@gate.crashing.org> (raw)
On a number of embedded reference boards there isn't always a
way to reset, power_off, or halt the board. Rather than having
each board implement a spin loop just let the generic code do
it.
