Subject: [PATCH 07/18] hw/sd: sd: Fix incorrect populated function switch status data structure
Date: Sat, 15 Aug 2020 00:40:45 +0800	[thread overview]
Message-ID: <1597423256-14847-8-git-send-email-bmeng.cn@gmail.com> (raw)
In-Reply-To: <1597423256-14847-1-git-send-email-bmeng.cn@gmail.com>

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

At present the function switch status data structure bit [399:376]
are wrongly pupulated. These 3 bytes encode function switch status
for the 6 function groups, with 4 bits per group, starting from
function group 6 at bit 399, then followed by function group 5 at
bit 395, and so on.

However the codes mistakenly fills in the function group 1 status
at bit 399. This fixes the code logic.
