[PATCH 7/8] board: phytec: phycore_am62ax: Share ethernet resources with boot r5 core

Tue Mar 25 04:58:23 CET 2025
From: Nathan Morrisson <nmorrisson at phytec.com>
During the U-Boot SPL R5 boot stage the code is running on the MAIN R5
core, which means a host ID of 36 is used for DM/TIFS communication,
see [1]. In order to enable Ethernet boot update the DMA resources used
to be shared with the MAIN R5 core instead of the MCU R5 core.

Based on patch 19 from https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1307981/sk-am62a-lp-rgmii-boot-mode-problem
