OP-TEE enables the use case of a secure interrupt triggered by the UART driver. This interrupt is routed by FFA_INTERRUPT interface to OP-TEE. Define the UART interrupt in the FF-A device region node. Without this change, OPTEE panics at the boot with the following: | I/TC: No non-secure external DT | I/TC: manifest DT found | I/TC: OP-TEE version: 4.3.0-23-gfcd8750677db | I/TC: WARNING: This OP-TEE configuration might be insecure! | I/TC: WARNING: Please check https://optee.readthedocs.io/en/latest/architecture/porting_guidelines.html | I/TC: Primary CPU initializing | E/TC:0 0 assertion '!res' failed at core/drivers/hfic.c:56 <hfic_op_enable> | E/TC:0 0 Panic at core/kernel/assert.c:28 <_assert_break> | E/TC:0 0 TEE load address @ 0x6284000 Change-Id: Icddcdfd032315aeee65ba3100f3a6b470a74435d Signed-off-by: Olivier Deprez <olivier.deprez@arm.com> Signed-off-by: Sudeep Holla <sudeep.holla@arm.com>
