Subject: [PATCH] mx7dsabresd: Boot in non secure by default
Date: Tue, 18 Feb 2020 16:09:59 -0300 [thread overview]
Message-ID: <20200218190959.13787-1-festevam@gmail.com> (raw)
Booting a mainline kernel in secure mode on i.MX7D causes only
one CPU to be brought up.
Change it to booting in non secure mode by default, which
allows the two CPUs to be brought up.
It does have a side effect of not probing the CAAM driver.
If CAAM driver is needed then a secure world OS such as OPTEE needs
to be used.
