Workaround for booting time crash in R-CarH3SK wth Kingfisher boardlamprey_12.1.0lamprey/12.1.012.1.0
When I run AGL Instrument Cluster with IVI in R-CarH3SK wth Kingfisher board, it's frequently crash at booting time. RGX driver has race condition issue at firmware download time. This issue occur in multi compositor environment such as IC container integration. This issue will fix by renesas in next BSP update time, may be. This patch enable workaround for this race condition issue. AGL-Bug : SPEC-4164 Change-Id: I5ca3affdfd681fd08391805ee765b3252afe190f Signed-off-by: Naoto Yamaguchi <naoto.yamaguchi@aisin.co.jp>
