Subject: [PATCH 3/3] ARM: i.MX6: boot: handle i.MX6UL differences
Date: Mon, 27 Apr 2020 09:13:51 +0200 [thread overview]
Message-ID: <20200427071351.467859-3-ahmad@a3f.at> (raw)
In-Reply-To: <20200427071351.467859-1-ahmad@a3f.at>
The i.MX6UL differs from the i.MX6Q in the interpretation of the first
two values for BOOT_CFG(7, 4):
+--------------+----------+----------+
|BOOT_CFG1(7,4)| 0x01 | 0x02 |
|==============+==========+==========|
| MX6Q | reserved | SATA |
|--------------+----------+----------|
| MX6UL | QSPI | reserved |
+--------------+----------+----------+
The reserved (forced serial) values are handled in the previous commit.
Add QSPI boot source detection now.
