Subject: [Buildroot] [PATCH 2/7] boot/uboot: add support for firmware-ele-imx
Date: Tue, 20 Oct 2026 12:28:56 +0200	[thread overview]
Message-ID: <20261020102906.1918308-2-peter@korsgaard.com> (raw)
In-Reply-To: <20261020102906.1918308-1-peter@korsgaard.com>

Similar to the existing firmware-imx support, some platforms need the
EdgeLock Secure Enclave firmware when building U-Boot:

https://docs.u-boot-project.org/en/v2026.10/board/nxp/imx93_frdm.html

So add an option for this and extend the existing UBOOT_COPY_IMX_FW_FILES
logic to also handle it.
