Subject: [U-Boot] [RFC PATCH 1/3] ARM: mx6: preserve Boot ROM stack in SPL
Date: Tue, 1 Nov 2016 19:06:32 -0700 [thread overview]
Message-ID: <1478052394-21499-2-git-send-email-eric@nelint.com> (raw)
In-Reply-To: <1478052394-21499-1-git-send-email-eric@nelint.com>
The i.MX6 Boot ROM starts its' stack at 0x091ffb4 and appears
to be a little less than 256 bytes deep when starting U-Boot.
This was determined experimentally on i.MX6DL and i.MX6SL.
Allow this stack to be preserved to simplify returning to
ROM when SPL is loaded as a plugin.
