Extend EGL/GLES hardware acceleration to various new Set-Top Box models,
including Octagon SF8008/SF8008m, GigaBlue gbmv200 series, and several
Zgemma H-series models.
This involves:
* Updating `configure.ac` and `openvix.conf` to recognize these devices,
configure their GLES capabilities, and enable their EGL backends.
* Adding new OpenEmbedded `bbappend` recipes to generate missing
pkg-config files and stage required EGL/GLES headers for vendor drivers.
* Refactoring the `ABCOM_EGL` backend to a more generic `HISI_MALI_EGL`
as it now applies to multiple HiSilicon-based brands.
* Implementing a specific Nexus `AuthenticatedJoin` path for Zgemma
Broadcom boxes (H7/H17) that do not ship `libnxclient.so`.

This pull request significantly expands and refines EGL/GLES support for a range of set-top boxes, particularly those using HiSilicon Mali-450 and Broadcom V3D GPUs. It unifies and generalizes the EGL backend and header/pkg-config file staging for these devices, adds support for several new machines, and cleans up the build configuration to be more maintainable and accurate.
The most important changes are:
EGL/GLES Backend Generalization and Expansion:
HAVE_ABCOM_EGLconditional with a more generalHAVE_HISI_MALI_EGLfor all HiSilicon Mali-450 (Utgard) devices, updating source lists and includes to usehisi_window_providerinstead ofabcom_window_provider. [1] [2]configure.acto group all HiSilicon Mali-450 devices (e.g.,pulse4k,hd61,sf8008,gbmv200, and various Zgemma models) under a single backend logic, disables GLES3 for these, and documents the changes. [1] [2] [3]Machine Support and Layer Configuration:
ax61,sf8008,sf8008m,gbip4k,gbtrio4k,gbtrio4kpro, and a wide range of Zgemma models, ensuring they are properly matched to their recipes and EGL/GLES support. [1] [2]Header and pkg-config Staging for EGL/GLES:
.bbappendrecipes that stage missing EGL/GLES headers and generateegl.pc/glesv2.pcpkg-config files, ensuring builds can find the correct headers and libraries even when vendor blobs are incomplete. [1] [2] [3] [4] [5] [6]Special Handling for Broadcom V3D and Zgemma Devices:
HAVE_NXPL_NO_NXCLIENTdefine for devices that lacklibnxclient.sobut join Nexus viaNEXUS_Platform_AuthenticatedJoin. [1] [2]Documentation and Minor Cleanups:
These changes collectively make EGL/GLES support more robust, consistent, and extensible across a broad range of hardware platforms.
