[PATCH v2 09/25] hw/sd: ssi-sd: Fix the wrong command index for STOP_TRA

From: Bin Meng
Subject: [PATCH v2 09/25] hw/sd: ssi-sd: Fix the wrong command index for STOP_TRANSMISSION
Date: Sat, 23 Jan 2021 18:40:00 +0800

From: Bin Meng <bin.meng@windriver.com>

This fixes the wrong command index for STOP_TRANSMISSION, the
required command to interrupt the multiple block read command,
in the old codes. It should be CMD12 (0x4c), not CMD13 (0x4d).

Fixes: 775616c3ae8c ("Partial SD card SPI mode support")
Signed-off-by: Bin Meng <bin.meng@windriver.com>


Changes in v2:
- Make this fix a separate patch from the CMD18 support
