From mboxrd@z Thu Jan 1 00:00:00 1970 From: Alexandru Gagniuc Date: Wed, 3 Feb 2021 09:21:07 -0600 Subject: [PATCH 1/5] spl: mmc: Support OP-TEE payloads in Falcon mode Message-ID: <20210203152111.1972017-1-mr.nuke.me@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de In general, Falcon mode means we're booting a linux kernel directly. With FIT images, however, an OP-TEE secure kernel can be booted before linux. Thus, if the next stage is an IH_OS_TEE, this isn't necessarily a problem. Of course, a general solution would involve mmc_load_image_raw_os() only loading the binary, and leaving the decision of suitability to someone else. However, a rework of the boot flow is beyond the scope of this patch. Accept IH_OS_TEE as a valid OS value.
