From 39913acedd673c815af06da8dc3ef04c6e674d4a Mon Sep 17 00:00:00 2001 From: Yangbo Lu Date: Wed, 17 Jun 2020 18:08:58 +0800 Subject: Move eSDHC adapter card identification to board files The eSDHC adapter card identification and multiplexing configuration through FPGA had been implemented in both common mmc driver and fsl_esdhc driver. However it is proper to move these code to board files and do it during board initialization. The FPGA registers are also board specific. This patch is to move eSDHC adapter card identification and multiplexing configuration from mmc driver to specific board files. And the option CONFIG_FSL_ESDHC_ADAPTER_IDENT is no longer needed.
