From c9836bf7c38f70623b2369b361d716b26b50f67c Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Wed, 5 Nov 2025 15:17:26 +0100 Subject: [PATCH] arm64: dts: ti: k3-am642-tqma64xxl: add boot phase tags Similar to other AM64x-based boards, add boot phase tags to make the Device Trees usable for firmware/bootloaders without modification. Supported boot devices are eMMC/SD card, SPI-NOR and USB (both mass storage and DFU). The I2C EEPROM is included to allow the firmware to select the correct RAM configuration for different TQMa64xxL variants.
