[PATCH v4 0/9] hw/sd: Support block read/write in SPI mode


From: Bin Meng
Subject: [PATCH v4 0/9] hw/sd: Support block read/write in SPI mode
Date: Thu, 28 Jan 2021 14:30:26 +0800

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

This includes the previously v3 series [1], and one single patch [2].

Compared to v3, this fixed the following issue in patch [v3,6/6]:
- Keep the card state to SSI_SD_CMD instead of SSI_SD_RESPONSE after
  receiving the STOP_TRAN token per the spec

All software tested so far (U-Boot/Linux/VxWorks) do work without
the fix, but it is better to comform with the spec.

In addition to [2], one more issue was exposed when testing with
VxWorks driver related to STOP_TRANSMISSION (CMD12) response.
