conf: Enable dynamic tpm-layer support for LUKS

2026-03-26T14:40:56+00:00

Add BBFILES_DYNAMIC registration for 'tpm-layer' collection to conditionally include LUKS recipes from dynamic-layers/tpm-layer/ when meta-security/meta-tpm layer is present. Add tpm-layer to LAYERRECOMMENDS to document the optional dependency for LUKS functionality. Update ti-core-initramfs.inc to auto-enable initramfs generation when DISTRO_FEATURES contains 'luks'.

ti-core-initramfs: Add TI_CORE_INITRAMFS_EXTRA_INSTALL

2026-02-12T15:11:19+00:00

Add TI_CORE_INITRAMFS_EXTRA_INSTALL variable that another layer can use to install additional packages/changes into the initramfs. Setting this variable will also turn on the initramfs even if the platform does not have kernel modules to include. Signed-off-by: Ryan Eatmon

ti-core-initramfs: Rework logic

2026-02-12T14:56:40+00:00

Clean up the logic of the new ti-core-initramfs to reduce the impact on downstream layers. - Flip the logic in the machine .conf files to track the list of required kernel modules for that platform, but if the variable is set to "" then the ti-core-initramfs will not be created. - Redo the logic of when we require creation/usage of the initramfs to just platforms that need it (ie that set TI_CORE_INITRAMFS_KERNEL_MODULES). - Add a big switch to disable the initramfs entirely. In that case, the user is on their own to make sure that the kernel has everything it needs to boot either via config fragments to turn on the needed modules, or by using the TI_CORE_INITRAMFS_KERNEL_MODULES variable to populate their own initramfs.
