[U-Boot] arm: mxs: No arch specific invalidate_icache_all available!

[Stefan Wahren]

Hi,

i tried to port our Duckbill (based on NXP i.MX28 SoC) to U-Boot
v2017.03 [1]. The startup works fine, except of this warning:

No arch specific invalidate_icache_all available!

I didn't found a MXS specific implementation of invalidate_icache_all().

Did i miss something? Shouldn't be the other MXS boards also affected?
