vbe: Record which phases loaded using VBE

2022-10-31T15:04:00Z

We expect VPL and SPL to load using VBE. Add a record of this so we can check it in U-Boot proper. Signed-off-by: Simon Glass

bloblist: Describe the design goals

2022-06-28T02:09:51Z

Add a comment explaining the design goals of bloblist, to make it easier for people to understand and comment on the structure. Signed-off-by: Simon Glass

bloblist: Update to use conditional value

2022-02-09T04:07:59Z

Use the new IF_ENABLED_INT() feature to avoid needing our own inline function to handle this case. Tidy up the logic to ensure that the value is only used when present. Update the 'expected' comment also. Signed-off-by: Simon Glass

bloblist: Relicense to allow BSD-3-Clause

2022-01-13T16:13:41Z

This implementation is intended to be copied to other projects and modified, to as to foster a standard means of communcating runtime information between firmware projects. The GPL-2 license is too restrictive for some projects, e.g. those intended as reference implementations rather than designed for collaborative open-source development. Update the license to make this easier to share. Signed-off-by: Simon Glass

bloblist: doc: Bring in the API documentation

2022-01-13T16:13:41Z

FIx up various minor errors and add the API documentation to the bloblist docs, since it is quite useful to see it in the same place. Signed-off-by: Simon Glass

bloblist: Add functions to obtain base address and size

2022-01-13T16:13:41Z

Add a few convenience functions to obtain useful information about the bloblist. Signed-off-by: Simon Glass

bloblist: Refactor Kconfig to support alloc or fixed

2022-01-13T16:13:41Z

At present we do support allocating the bloblist but the Kconfig is a bit strange, since we still have to specify an address in that case. Partly this is because it is a pain to have CONFIG options that disappears when its dependency is enabled. It means that we must have #ifdefs in the code, either in the C code or header file. Make use of IF_ENABLED_INT() and its friend to solve that problem, so we can separate out the location of bloblist into a choice. Put the address and size into variables so we can log the result. Add the options for SPL as well, so we can use CONFIG_IS_ENABLED(). Signed-off-by: Simon Glass

bloblist: Use explicit numbering for the tags

2022-01-13T16:13:41Z

At present if someone adds a tag in the middle of the list it works well enough within a U-Boot build. But if these tags are used in another project, or with an older version of SPL, the numbers make become inconsistent. Use explicit tag numbers that never change, to resolve this problem. Allocate areas for existing U-Boot tags and set up an area for use by projects and vendors, as well as for private use. Keep tags above 0x10000 unallocated for now. Update bloblist_tag_name() and the tests to work with this new setup. Signed-off-by: Simon Glass

bloblist: Drop unused tags

2022-01-13T16:13:41Z

The EC event log tag is no-longer used. The vboot handoff is now handled by the vboot context instead. Drop these unused tags. Signed-off-by: Simon Glass

bloblist: Rename the SPL tag

2022-01-13T16:13:41Z

Add a U_BOOT prefix to this tag since it is specific to the U-Boot project. Signed-off-by: Simon Glass
