[Qemu-devel] [PATCH 3/4] LSI53C895A: Implement TARGET RESET message

[Ryan Harper <ryanh@us.ibm.com>]

Linux and Windows send a TARGET RESET message to the device when it fails to
respond as it expects.  For example, when it tries to select LUN1, which we
don't support.  This patch is needed to support the Linux sym53c8xx_2
driver when configured with SYM_CONF_DMA_ADDRESSING_MODE=2
