lib: uuid: supporting building as part of host tools

2024-09-12T15:35:37+00:00

Adjust the UUID library code so that it can be compiled as part of a
host tool.

This removes the one redundant log_debug() call, as well as the
incorrectly defined LOG_CATEGORY.

In general this is a fairly trivial change, just adjusting includes and
disabling list_guid.

This will be used by a new genguid tool to generate v5 GUIDs that match
those generated by U-Boot at runtime.

lib: uuid: add UUID v5 support

2024-09-12T15:35:37+00:00

Add support for generating version 5 UUIDs, these are determistic and work
by hashing a "namespace" UUID together with some unique data. One intended
usecase is to allow for dynamically generate payload UUIDs for UEFI
capsule updates, so that supported boards can have their own UUIDs
without needing to hardcode them.

In addition, move the common bit twiddling code from gen_ran_uuid into a
separate function and rewrite it not to use clrsetbits (which is not
available when building as part of host tools).

Tests for this are added in an upcoming patch.

uuid: Move function comments to header file

2023-08-25T21:55:18+00:00

These should be in the header file for easy browsing, not in the source
code. Move them and add a missing Return on one of the functions.

uuid: Add a comment for UUID_STR_LEN

2021-01-27T22:03:16+00:00

This macro is the length of the string but excludes the terminator. Users
must add 1 when declaring a large-enough string. Add a comment to make
this clear.

lib/uuid.c: change prototype of uuid_guid_get_str()

2021-01-16T19:49:09+00:00

There's no reason to require an appropriately sized output parameter
for the string, that's error-prone should the table ever grow an
element with a longer string. We can just return the const char*
pointer directly.

Update the only caller accordingly, and get rid of pointless ifdeffery
in the header so that the compiler always sees a declaration and can
thus do type-checking, whether or not PARTITION_TYPE_GUID is enabled
or not.
