Subject: [PATCH 0/3] ARM64 early cache fixes
Date: Thu, 19 Dec 2019 10:13:07 +0100 [thread overview]
Message-ID: <20191219091310.27421-1-l.stach@pengutronix.de> (raw)
This is a resend of the 2 ARM64 early cache fixes by Ahmad. They were
not applied at the time, as there was a report of them breaking Barebox
on i.MX8M. I finally had time to look into that, the first patch by
me cleans the stage, so the cache fixes no longer break anything.
At least the icache invalidation patch fixes an issue I hit on one
system, were minimal (harmless) changes to the Barebox code would
break execution.
Regards,
Lucas
