AFAIR, there's a bit of a caveat to that errata, since it applies only to multi-core systems or systems with ACP, so some of the cores might not need it and IMHO in order to properly apply that errata one would have to consult individual SoC's reference manuals. But the main reason why I applied it only there was that there didn't seem to be a common place where those erratas are applied for all platforms (I suspect it might have to do with the fact that it is possible to build BB for multiple generations or ARM), but there was a place where erratas were applied for i.MX6, so I followed the path of least resistance. > > Mit freundlichen Grüßen / Kind regards, > Stefan Christ > > On Tue, Mar 15, 2016 at 08:33:47PM -0700, Andrey Smirnov wrote: >> Signed-off-by: Andrey Smirnov <andrew.smirnov@xxxxxxxxx> >> --- >> arch/arm/mach-imx/cpu_init.c | 1 + >> 1 file changed, 1 insertion(+) >> >> diff --git a/arch/arm/mach-imx/cpu_init.c b/arch/arm/mach-imx/cpu_init.c >> index 8b10e63..7603883 100644 >> --- a/arch/arm/mach-imx/cpu_init.c >> +++ b/arch/arm/mach-imx/cpu_init.c >> @@ -31,4 +31,5 @@ void imx6_cpu_lowlevel_init(void) >> enable_arm_errata_751472_war(); >> enable_arm_errata_761320_war(); >> enable_arm_errata_794072_war(); >> + enable_arm_errata_845369_war(); >> } >> -- >> 2.5.0 >> >> >> _______________________________________________ >> barebox mailing list >> barebox@xxxxxxxxxxxxxxxxxxx >> http://lists.infradead.org/mailman/listinfo/barebox _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
