From e936e0ec5888138c1984e3c807971ecf69a6a548 Mon Sep 17 00:00:00 2001 From: Quentin Schulz Date: Thu, 15 Sep 2022 11:14:23 +0200 Subject: [PATCH] rockchip: puma-rk3399: allow non-SD-Card-loaded SPL to load U-Boot proper from SD-Card Trying to load U-Boot proper from SPL when SPL was not loaded from SD-Card is currently not working because the SDMMC pins aren't muxed correctly. It is assumed the BootROM is doing this for us when booting from SD-Card hence why it's not needed when booting TPL/SPL from SD-Card. The pinctrl properties are removed from the SPL DT property removal list and the pinctrl configuration nodes made available in the SPL DT, in addition to the pull-up configurations to allow loading U-Boot proper from SD-Card as a fallback mechanism for SPI-NOR and eMMC.
