To: u-boot
From: Dirk Eibach <eibach@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@gdsys.cc>
---
Changes in v5:
- add board/gdsys/common/fpga.c which was forgotten in v4
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

Changes in v5: None
Changes in v4:
- Move changes ins osd.c to proper commit
- do not use common FPGA register accessors here
Changes in v3:
- adapt to "powerpc/ppc4xx: Use generic accessor functions for gdsys FPGA"
- squashed with powerpc/ppc4xx: Fixup phy erratum on gdsys iocon hardware
Changes in v2:
- fpga_state has been moved to arch_global_data
- include cmd_fpgad in iocon
- use multibus soft-i2c in iocon

OSD size was constant 32x16 characters.
Now the size is set as announced by the FPGA.

From: Dirk Eibach <eibach@gdsys.de>
CONFIG_SYS_FLASH_PROTECTION was active on most gdsys boards by default,
while hardware flash protection was not implemented.
Hardware support was added recently and we get into trouble because backward
compatibility is broken (u-boot can't unprotect the protected flash after a
downgrade). So we decided to disable hardware flash protection for all our boards.
