From c4d660d4d0abcde0fdbcee8401b215fc2b56d7aa Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 4 Jul 2017 13:31:19 -0600 Subject: dm: mmc: Allow disabling driver model in SPL At present if U-Boot proper uses driver model for MMC, then SPL has to also. While this is desirable, it places a significant barrier to moving to driver model in some cases. For example, with a space-constrained SPL it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves adjusting some drivers. Add new SPL versions of the options for DM_MMC, DM_MMC_OPS and BLK. By default these follow their non-SPL versions, but this can be changed by boards which need it.
