[RFC PATCH v2 01/11] MIPS: Alchemy: au1000 header file cleanup
From: Manuel Lauss
Date: Thu Jul 03 2014 - 09:25:42 EST
- remove the custom au_read/write{bwl} accessors as well as au_sync,
and replace them with __raw_readl/writel/wmb
- changes absolute register addresses to offsets from their base:
- rename the SYS_xxx definitions to AU1000_SYS_ so people know
that addresses have changed.
- add helpers to read/write SYS registers, and use them.
- removes unused register/bit definitions (unused hw blocks, ...)
- moves ethernet register/bit descriptions to au1000_eth driver.
No functional changes.
Tested on DB1300 and DB1500.
Signed-off-by: Manuel Lauss <manuel.lauss@xxxxxxxxx>
