Subject: [PATCH 1/4 V2] powerpc/85xx: Add support for 85xx cpu type detection
Date: Wed, 10 Jul 2013 15:39:01 +0800 [thread overview]
Message-ID: <1373441941-32650-1-git-send-email-Haijun.Zhang@freescale.com> (raw)
Add this file to help detect cpu type in runtime.
These macros will be more favorable for driver
to apply errata and workaround to specified cpu type.

changes v2:
- Remove inline function
- Ignore E bit of SOC
- Add Macro to get current soc version
