Subject: [PATCH] hw/sd: sd: Bypass the RCA check for CMD13 in SPI mode
Date: Fri, 29 Jan 2021 16:51:24 +0800 [thread overview]
Message-ID: <20210129085124.21525-1-bmeng.cn@gmail.com> (raw)
From: Bin Meng <bin.meng@windriver.com>
Unlike SD mode, when SD card is working in SPI mode, the argument
of CMD13 is stuff bits. Hence we should bypass the RCA check.
