Subject: [PATCH v2 2/4] hw/msic: imx6_ccm: Correct register value for silicon type
Date: Wed, 23 Dec 2020 14:26:05 +0800	[thread overview]
Message-ID: <1608704767-9317-3-git-send-email-bmeng.cn@gmail.com> (raw)
In-Reply-To: <1608704767-9317-1-git-send-email-bmeng.cn@gmail.com>

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

Currently when U-Boot boots, it prints "??" for i.MX processor:

  CPU:   Freescale i.MX?? rev1.0 at 792 MHz

The register that was used to determine the silicon type is
undocumented in the latest IMX6DQRM (Rev. 6, 05/2020), but we
can refer to get_cpu_rev() in arch/arm/mach-imx/mx6/soc.c in
the U-Boot source codes that USB_ANALOG_DIGPROG is used.

Update its reset value to indicate i.MX6Q.
