[U-Boot] [PATCH v3 0/7] Enable falcon boot for LS1043ARDB

[York Sun]

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.
