Multiple images for SPL
|
|
=======================
|
|
|
|
(Bogus) example FIT image description file demonstrating the usage
|
|
of multiple images loaded by the SPL.
|
|
Several binaries will be loaded at their respective load addresses.
|
|
|
|
For booting U-Boot, "firmware" is searched first. If not found, "loadables"
|
|
is used to identify images to be loaded into memory. If falcon boot is
|
|
enabled, "kernel" is searched first. If not found, it falls back to the
|
|
same flow as booting U-Boot. Changing image type will result skipping
|
|
specific image.
|
|
|
|
Finally the one image specifying an entry point will be entered by the SPL.
