Subject: [PATCH v2] imx: Enable ACTLR.SMP in SPL for i.MX6/7
Date: Sat, 5 Feb 2022 17:42:25 +0100 (CET) [thread overview]
Message-ID: <20220205164228.C490683BB0@phobos.denx.de> (raw)

> Similar to what has been done before with c5437e5b for u-boot proper, we
> enable the SMP bit for SPL as well. This is necessary when SDP booting
> straight into Linux, i.e. falcon boot. When SDP boot mode is active, the
> ROM code does not set this bit which makes the caches not work once
> activated in Linux.
> On an i.MX6ULL (528MHz), this reduces a minimal kernel's boot time into
> an initramfs shell from ~6.1s down to ~1.2s.
