Looks like CONFIG_ARCH_DMA_ADDR_T_64BIT=y is missing. For e.g. CAAM (crypto engine) is a DMA device able to use 40-bit bus addresses. Note that ARCH_DMA_ADDR_T_64BIT does not depend / is not selected by ARM_LPAE. Thanks, Horia

Another thing: Commit 385c0fb0e2c4 ("ARM: imx_v6_v7_defconfig: Select LS1021A") added CONFIG_SOC_LS1021A in imx_v6_v7_defconfig. Besides this, booting a LS1021 AQDS board (Rev2) using imx_v6_v7_defconfig did not work (stuck at "Starting kernel"). Horia

What would be the recommended approach? - Fix imx_v6_v7_defconfig so that it can make LS1021A to boot or - Use this proposed ls1021a_defconfig and remove LS1021A from imx_v6_v7_defconfig? Regards, Fabio Estevam
Hi, Fabio, Based on the analysis and discussion, we prefer to use ls1021a_defconfig and remove LS1021A from imx_v6_v7_defconfig. Thanks.

[Alison Wang] I don’t know CONFIG_ARCH_DMA_ADDR_T_64BIT=y is suggested. Could you help to explain the suggestion? I need Fabio's confirmation about removing CONFIG_SOC_LS1021A from imx_v6_v7_config.

Yes, if Shawn accepts ls1021a_defconfig then we should remove CONFIG_SOC_LS1021A from imx_v6_v7_config. Regards, Fabio Estevam

Can you please resend the patch with some explanation in the commit log on why we need a new defconfig, i.e. why imx_v6_v7_config doesn't work for LS1021A. Shawn
