From 04fef228fb00dd79475a2313f4ba73b4fbfe2faa Mon Sep 17 00:00:00 2001 From: Eric Miao Date: Tue, 29 Jul 2008 14:26:00 +0800 Subject: [ARM] pxa: introduce reset_status and clear_reset_status for driver's usage Due to the problem of reset status bits being handled by different registers between pxa2xx and pxa3xx, introduce a global reset_status variable, initialized by SoC-specific code and later being used by other drivers. And also introduce clear_reset_status(), which is used to clear the corresponding status bits. Pass RESET_STATUS_ALL to clear all bits.
