Subject: [PATCH 07/23] ARM: i.MX8M: imx8m_tfa_start_bl31() add support for bl33 and fdt
Date: Mon, 10 Nov 2025 21:34:47 +0100	[thread overview]
Message-ID: <20251110-v2025-09-0-topic-optee-of-handling-v1-7-8f0625ac5471@pengutronix.de> (raw)
In-Reply-To: <20251110-v2025-09-0-topic-optee-of-handling-v1-0-8f0625ac5471@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.
