From 8f3f8ba945f7e6b4225b2a5f171a64f7679bc8ba Mon Sep 17 00:00:00 2001 From: =?utf8?q?Pali=20Roh=C3=A1r?= <pali@kernel.org> Date: Wed, 11 May 2022 20:27:13 +0200 Subject: [PATCH] mmc: fsl_esdhc: Add new config option for default fallback mode MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently default fallback SDHC mode is 1-bit. Add new config option CONFIG_SYS_FSL_ESDHC_DEFAULT_BUS_WIDTH to allow specifying default fallback mode. This is useful e.g. for SPL builds which loads other parts from SD card during boot process.
