- use I/O accessors -> For accessing the FPGA therefore a struct km_bec_fpga is introduced. - no longer externs needed - to defines, that only select functions, don;t assign a numeric value - Codingstyle changes to prevent checkpatch errors/warnings Signed-off-by: Heiko Schocher <hs@denx.de> cc: Kim Phillips <kim.phillips@freescale.com> cc: Holger Brunck <holger.brunck@keymile.com> cc: Wolfgang Denk <wd@denx.de> cc: Detlev Zundel <dzu@denx.de> cc: Valentin Longchamp <valentin.longchamp@keymile.com> cc: Prafulla Wadaskar <prafulla@marvell.com> --- Changes for v3: - new in this patchset, to prevent a lot of checkpatch errors/warnings Changes for v4: - correct struct km_bec_fpga board/keymile/common/common.c | 347 ++++++++++++++++++-------------------- board/keymile/common/common.h | 40 ++++- board/keymile/km_arm/km_arm.c | 25 ++-- board/keymile/kmeter1/kmeter1.c | 122 +++++++------- board/keymile/mgcoge/mgcoge.c | 82 +++++----- include/configs/keymile-common.h | 62 ++++---- include/configs/km_arm.h | 8 +- include/configs/kmeter1.h | 104 +++++++----- include/configs/mgcoge.h | 107 +++++++----- 9 files changed, 476 insertions(+), 421 deletions(-)
