From: Peng Fan Date: Thu, 15 Jun 2023 10:09:18 +0000 (+0800) Subject: imx: bootaux: change names of MACROs used to boot MCU on iMX devices X-Git-Url: http://git.dujemihanovic.xyz/img/static/%7B%7B%20%24.Site.BaseURL%20%7D%7Dposts/index.xml?a=commitdiff_plain;h=9395eb05ee816fd8e5082e10e84391e5a621d9f0;p=u-boot.git imx: bootaux: change names of MACROs used to boot MCU on iMX devices The current bootaux supports i.MX8M and i.MX93, but the name "_M4_" implies that the SoCs have Cortex-M4. Actually i.MX8MM/Q use Cortex-M4, i.MX8MN/P use Cortex-M7, i.MX93 use Cortex-M33, so use "_MCU_" in place of "_M4_" to simplify the naming.
