This is the 3rd version to enable falcon boot for LS1043ARDB. With SPL FIT patches merged, enabling falcon boot for this board is straight forward after fixing some errors introduced by other commits.
Falcon boot is not enabled by default due to a conflict with recent PPA image update, which takes over entire OCRAM after being loaded. With a compatible PPA image (older version or future update), falcon boot can be enabled as described in commit message.
Secure boot is dropped in this set due to SPL image size issue. Recent changes made the SPL image bigger and the secure boot image doesn't fit any more. A follow-up patch set will enable secure boot if the image can be future trimmed to fit.
Changes in v3: Create new function to fill gd->bd for spl. Use git commit description style when mentioning previous commit. Fix typo in subject and other cosmetic fix. Drop defconfig change Not to enable falcon boot by default due to a conflict with recent PPA
Changes in v2: New patch to fix spl after rebasing to latest master. New patch to fix compiling error after rebasing to latest mater. New patch to fix gd->ram_size error after rebasing to latest mater. Drop checking secure boot in this patch after rebasing to latest mater. Recent change in SPL makes the image size bigger. Relace getenv_f() with env_get_f() after rebasing to latet master.
