Subject: [PATCH v3 03/14] ARM: i.MX8M: imx8m_tfa_start_bl31() add support for bl33 and fdt
Date: Wed, 11 Feb 2026 23:41:14 +0100	[thread overview]
Message-ID: <20260211-v2025-09-0-topic-optee-of-handling-v3-3-dd83358ae624@pengutronix.de> (raw)
In-Reply-To: <20260211-v2025-09-0-topic-optee-of-handling-v3-0-dd83358ae624@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.
