[PATCH 0/2] hw/sd: Fix broken ssi-sd implementation since v9.1.0

[Bin Meng <bmeng.cn@gmail.com>]

The U-Boot community reported a CI failure [1] where the
`sifive_unleashed` target failed to boot from an SD card after
upgrading from QEMU v8.2.0 to v9.2.3.

At that time, the issue was traced to commit da954d0e
("hw/sd/sdcard: Add spi_cmd_SEND_CSD/CID handlers (CMD9 & CMD10)")
which was introduced in v9.1.0.

Testing with the latest QEMU mainline shows that the problem still
persists, although the underlying cause has changed due to refactoring
since then.

This series fixes the broken `ssi-sd` model. After applying these
patches, U-Boot successfully boots again on the `sifive_unleashed`
target using QEMU’s `sifive_u` machine.
