[U-Boot] [PATCH v4 1/6] powerpc/ppc4xx: Use generic accessor functions for gdsys FPGA
dirk.eibach at gdsys.cc
dirk.eibach at gdsys.cc
Thu Jun 20 15:15:33 CEST 2013
From: Dirk Eibach <eibach at gdsys.de>
A set of accessor functions was added to be able to access not only
memory mapped FPGA in a generic way.
Thanks to Wolfgang Denk for getting this sorted properly.
Signed-off-by: Dirk Eibach <dirk.eibach at gdsys.cc>
---
Changes in v4:
- Move unrelated changes ins osd.c to proper commit
- explain why fpga_gpio_ functions are actually useful
- factor out common code for fpga register access
- use macro instead of #ifdef for reflection test
Changes in v3:
- squashed with "Add generic accessor functions for gdsys FPGA"
- strictly replace base address plus offset with proper C structs
Changes in v2: None
