Subject: [PATCH v2 03/15] ARM: i.MX8M: imx8m_tfa_start_bl31() add support for bl33 and fdt
Date: Wed, 04 Feb 2026 21:01:19 +0100 [thread overview]
Message-ID: <20260204-v2025-09-0-topic-optee-of-handling-v2-3-da075e6818e0@pengutronix.de> (raw)
In-Reply-To: <20260204-v2025-09-0-topic-optee-of-handling-v2-0-da075e6818e0@pengutronix.de>
This adds the support to pass the bl33 entry and the fdt to
imx8m_tfa_start_bl31() which is required to pass it later on the the
bl31 via the bl_params.
