[PATCH v4 0/19] Allow images to work on sandbox

[Simon Glass]

This series adjusts the image code to work with sandbox and prepares it for
verified boot to come later.

The primary goal here is to get image loading to work on sandbox, which is
mostly a set of fairly minor changes such as using map_sysmem() instead of
just a cast when converting from a U-Boot address to a pointer. Since
common/image.c runs to over 3000 lines and half of it is FIT-related code
behind an #ifdef, this code is moved into a new image-fit.c file.

Changes in v4:
- Bring in upstream version of fdt_first/next_subnode()
- Use new upstream fdt_first/next_subnode()

Changes in v3:
- Split out image improvements into a separate series
- Update notes to note that generic board support has now landed

Changes in v2:
- Add IMAGE_ENABLE_IGNORE to avoid #ifdef around ignore property handling
- Change hash_block() to use an unsigned int len
- Clarify use of output_size parameter to hash_block()
- Fix checkpatch checks about parenthesis alignment
- Fix line continuation problem
- Put err_msgp strings on a single line
- Put params before description in fit_conf_get_prop_node() comment
- Rebase on previous patches
- Rename commit message to say "function" instead of "function"
