Subject: [PATCH] ARM: OMAP2+: PRCM: create SoC-specific chip restart
 functions

Split omap_prcm_restart() from mach-omap2/prcm.c into SoC-specific
variants.  These functions need to be able to save the reboot reason
into the scratchpad RAM.  This implies a dependency on both the PRM
and SCM IP blocks, so they've been moved into their own file.  This
will eventually call functions in the PRM and SCM drivers, once those
are created.

Vaibhav Hiremath hvaib...@ti.com identified an unused prototype in
the first version of this patch - now removed.  Tony Lindgren
t...@atomide.com noted a compile problem with some RMK Kconfigs;
resolved in this patch.

[PATCH 05/13] ARM: OMAP2+: PRCM: create SoC-specific chip restart functions

2012-10-25 Thread Paul Walmsley 
Split omap_prcm_restart() from mach-omap2/prcm.c into SoC-specific
variants.  These functions need to be able to save the reboot reason
into the scratchpad RAM.  This implies a dependency on both the PRM
and SCM IP blocks, so they've been moved into their own file.  This
will eventually call functions in the PRM and SCM drivers, once those
are created.
