From a49460c6b6e54bf09945263e8a57119e813f6de5 Mon Sep 17 00:00:00 2001 From: Wenbin Mei Date: Wed, 8 Jun 2022 16:37:00 +0800 Subject: soc/mediatek: pass access mode to the payload Some eMMCs (for example, Kingston-EMMC64G-TX29-HP) may enter the ready state by sending CMD1 twice. If it is in the ready state, then the payload (for example, depthcharge) will not send CMD1, but the access mode is only available from the response of CMD1. Therefore, we need to pass the access mode to the payload by defining the following types: - MMC_STATUS_CMD1_READY: in ready state and access mode is byte mode. - MMC_STATUS_CMD1_READY_HCS: in ready state and access mode is sector mode.
