From b9d66a061b93e4679bd3afddb24413d5a51dabcc Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Mon, 30 Aug 2021 09:16:29 -0400 Subject: imx: Convert SERIAL_TAG support to ENV_VARS_UBOOT_RUNTIME_CONFIG No iMX platforms have supported ATAG-based booting. They have however re-used the CONFIG_SERIAL_TAG option as a way to enable support of reading the OTP fuses and setting the serial# environment variable in some cases. Change the warp7 support to use this symbol, use this for updating the rest of the imx7 code, and update the imx8 conditionals.
