Subject: [PATCH 1/3] ARM: imx25: support silicon revision 1.2
Date: Thu, 2 Jun 2022 10:03:42 +0200 [thread overview]
Message-ID: <20220602080344.208702-2-martin@kaiser.cx> (raw)
In-Reply-To: <20220602080344.208702-1-martin@kaiser.cx>
Update the mx25_read_cpu_rev function to recognize silicon revision 1.2
for imx25 chipsets.
Silicon revision 1.2 is mentioned in the errata document at
https://www.nxp.com/docs/en/errata/IMX25CE.pdf. The imx25 chips on my
test boards show revision 1.2 as well.
