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 benoit.thebaudeau@advansee.com --- 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.
