[PATCH 04/22] hw/sd: sd: Support CMD59 for SPI mode

From: Bin Meng
Subject: [PATCH 04/22] hw/sd: sd: Support CMD59 for SPI mode
Date: Thu, 31 Dec 2020 19:29:52 +0800

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

After the card is put into SPI mode, CRC check for all commands
including CMD0 will be done according to CMD59 setting. But this
command is currently unimplemented. Simply allow the decoding of
CMD59, but the CRC check is still ignored.
