IIM: - Homogenize prg_p naming (the reference manuals are not always self-consistent for that). - Add missing SCSx and bank registers. - Fix the number of banks on i.MX53.
OCOTP: - Rename iim to ocotp in order to avoid confusion. - Rename fuse_data to read_fuse_data, and sticky to sw_sticky, according to the reference manual. - Merge the existing spinoff gp1 fuse definition on i.MX6. - Fix the number of banks on i.MX6. Signed-off-by: Benoît Thébaudeau <[email protected]> --- Changes in v4: - Convert spaces to tabs. Changes in v3: - Rebase against latest u-boot-imx/master. - Fix the number of banks on i.MX6. - Rename iim to ocotp on i.MX6 in order to avoid confusion, and merge in the existing gp1 fuse definition. - Rename fuse_data to read_fuse_data, and sticky to sw_sticky, according to the reference manual. Changes in v2: - Rebase against latest master. arch/arm/cpu/armv7/mx6/soc.c | 4 ++-- arch/arm/include/asm/arch-mx25/imx-regs.h | 8 ++++++-- arch/arm/include/asm/arch-mx27/imx-regs.h | 2 +- arch/arm/include/asm/arch-mx31/imx-regs.h | 9 +++++++-- arch/arm/include/asm/arch-mx35/imx-regs.h | 7 ++++++- arch/arm/include/asm/arch-mx5/imx-regs.h | 6 +++++- arch/arm/include/asm/arch-mx6/imx-regs.h | 19 +++++++------------ board/freescale/mx6qsabreauto/mx6qsabreauto.c | 5 ++++- 8 files changed, 38 insertions(+), 22 deletions(-) diff --git a/arch/arm/cpu/armv7/mx6/soc.c b/arch/arm/cpu/armv7/mx6/soc.c index 69b8487..fc436fb 100644 --- a/arch/arm/cpu/armv7/mx6/soc.c +++ b/arch/arm/cpu/armv7/mx6/soc.c @@ -172,8 +172,8 @@ void enable_caches(void) #if defined(CONFIG_FEC_MXC) void imx_get_mac_from_fuse(int dev_id, unsigned char *mac) { - struct iim_regs *iim = (struct iim_regs *)IMX_IIM_BASE;
