[U-Boot] [PATCH v3 00/21] spl: Add features for passing info from SPL to U-Boot proper

[Simon Glass]

At present we have no standard way of passing information from SPL to
U-Boot. Such information may be the size of DRAM banks or some information
about the reset state of the machine,for example.

This series first adds a bloblist, which allows a list of 'blobs' to be
created, each with a tag so that subsystems can store data and retrieve it
later. Then it adds the SPL 'handoff' information, which uses bloblist.

Various minor sandbox enhancements are provided to make this easier, or to
support testing.

Changes in v3:
- Add comments to the log_ret() functions to indicate usage
- Update log_msg_ret() to make use of the message and avoid a warning
- Correct CONFIG_BLOBLIST_ADDR to have a default only for sandbox
- Drop patch 'spl: Print a message if we are unable to load an image'

Changes in v2:
- Fix several typos
- Add back a blank line, and put one in the new function too
- Drop the wildcard in the .lds file as it is not needed
