Thu Mar 24 13:27:55 CET 2011
Add generic header files support for nds32 architecture.
Cache, ptregs, data type and other definitions are included.
Signed-off-by: Macpaul Lin <macpaul at andestech.com>
---
Changes for v1-v4:
- Code cleanup and style formatting.
Changes for v5-v6:
- This patch also updated the following changes against the
change after master tree (v2010.12-rc1).
- fix upper case definitions in cache.h
- Support GD_FLG_ENV_READY and env_buf vars in nds32 global_data.h.
- Add readsb, writesb functions into io.h.
