Renesas is seen as the 'second' best upstreaming ARM-SoC. + The first is ATMEL which is so small it's incomparable - they have less work to do :) + +* CPUidle: +** Get clarification of real issues (SYSC CPU/GSX concurrency?) +** Enable when we get newer SoC revisions where the hardware has been fixed + +* IPMMU +** Unusable on H3 before ES3.x.. +** E3/M3 might be OK (because they are newer) +** 32-bits IOVA space status?
