Hi team,

 

I would like to ask about the implementation of work-around for ARM Errata#845369 in your AndroidBSP.

I found the discussion about this errata #845369 in i.MX community.

https://community.freescale.com/thread/371109

 

It is said that the work-around is included in your recent Android BSP L5.0 in the discussion.

(1)

Can I understand that the patch will be included in your latest, in future, Android BSPs after the L5.0 continuously?

 

(2)

Could you show me whether the patch code is needed for the early version of AndroidBSP than L5.0?

I found the similar code was included in JB and KK as a work-around of ARM/Errata#742231.

I believe that the workaround of #845369 (setting bit22 of P15 register) is implemented as a workaround of #742231 in JB and KK. Then there is no need to implement the workaround of #845369 anymore for JB and KK.

Am I right?

 

Thanks,

Miyamoto
