From 61f4e5f9cfa77d0b4f8fd69f6e7c3fd4cc5b519c Mon Sep 17 00:00:00 2001 From: Jonas Karlman Date: Tue, 5 Nov 2024 21:51:46 +0000 Subject: [PATCH] rockchip: rk3288-miqi: Fix slow Ethernet initializion For some reason the Ethernet PHY reset delay is set to 1 second, this cause an unneccecery long boot delay. MiQi use RTL8211 Ethernet PHY, datasheet list an initial 10ms delay and then a 30-76ms delay before accessing registers. Change to use 80ms delay instead of a full second to speed up Ethernet initializion in U-Boot. Also enable PHY_REALTEK, DM_ETH_PHY and PHY_GIGE to improve Ethernet PHY support in U-Boot.
