* Add MXQ target. Copy HDMI fix from odroid-c1. * meson8, MXQ: add boot from usb support, configurable dtb * MXQ: remove boot logo Built-in U-BOOT is used, so the logo will not be displayed anyway. * meson: kernel update: legacy -> 6.6, current -> 6.12 * Change Odroid C1 and Onecloud to community supported as build now passes --------- Co-authored-by: Igor Pecovnik <igor@armbian.com>

Subject: dt-bindings: firmware: Document the Amlogic Meson6/8/8b/8m2 TrustZone
|
|
|
|
Amlogic Meson6/8/8b/8m2 SoCs can optionally use a TrustZone secure
|
|
firmware. This prevents anything outside of the TEE (Trusted
|
|
Execution Environment aka TrustZone secure firmware) from accessing
|
|
certain functionality of these SoCs, such as (but not limited to):
|
|
Bringing up/down secondary SMP cores, accessing the eFuse and getting
|
|
the SoC misc version.
|
|
ARM SMCCC is used for communication with the TrustZone secure
|
|
firmware.
