feat(lfa): add relocatable code for BL31 live activation2026-06-30T14:56:36+00:00John Powelljohn.powell@arm.com2026-05-18T17:52:12+00:00urn:sha1:567e4357fb29be24ab5917102d2a5ed6f6feba4d
This patch adds the relocatable code functions that are copied
out of the main BL31 image during a live activation and updates
the holding pen code to have a relocatable variant.

feat(rmmd): replace ENABLE_RME with ENABLE_RMM2026-04-08T10:03:13+00:00Arunachalam Ganapathyarunachalam.ganapathy@arm.com2025-11-04T13:41:47+00:00urn:sha1:b0ddba24fe15ae6dd1d23eae165496de86e3a923
RME architectural requirements are now handled under the feature
detection option ENABLE_FEAT_RME. However, the existing ENABLE_RME build
option performs RMM-specific tasks such as GPT setup, loading the RMM,
and enabling RMMD support.
Since ENABLE_RME now only controls RMM-related functionality, rename it
to ENABLE_RMM to better reflect its purpose and avoid confusion with
ENABLE_FEAT_RME.
For backward compatibility, setting the legacy ENABLE_RME=1 (until it is
deprecated) will automatically enable both ENABLE_FEAT_RME and
ENABLE_RMM.

feat(lfa): add LFA holding pen logic2025-06-20T11:51:29+00:00Manish V BadarkheManish.Badarkhe@arm.com2025-04-15T19:16:36+00:00urn:sha1:ff7daec6f4bd151a1787c12db546509db49597df
Add LFA holding logic to be used by the LFA activate SMC call to manage
CPU rendezvous. All CPUs are expected to invoke the LFA activate call
for the rendezvous, until then, they will remain on a holding lock.
When the final CPU calls LFA activate, it will release the holding
lock after completing the activation process on that CPU, allowing
the activation process on secondary CPUs to proceed.

feat(lfa): implement LFA_GET_INFO SMC and integrate LFA build2025-06-20T08:32:22+00:00Manish V BadarkheManish.Badarkhe@arm.com2025-05-30T12:17:05+00:00urn:sha1:b9dee50c5419d351effa60fb995a6dd1724a4031
Implement the LFA_GET_INFO SMC handler, which retrieves the
number of supported firmware components and performs initial
setup via the platform APIs. This forms the entry point for
LFA usage and makes component metadata available for later use.
Update the build system to include LFA sources.

feat(lfa): create LFA SMC handler template2025-06-20T08:32:05+00:00Manish V BadarkheManish.Badarkhe@arm.com2025-04-15T19:16:32+00:00urn:sha1:cf48f49fd352b3c68635677c1564a449d3745930
As per the specification v1.0[1], added all Live Firmware Activation
(LFA) SMCs, including their Function IDs (FIDs) and associated error
codes.
A dummy handler function has been created as a template. Subsequent
patches will implement the handling of these SMCs.
