From d2a47176a877b1eccd3086a4c8d790d644d594cb Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Thu, 8 Jun 2017 15:23:08 +0200 Subject: mmc: core: Remove MMC_CAP2_HC_ERASE_SZ The MMC_CAP2_HC_ERASE_SZ is used only by a few mmc host drivers. Its intent is to enable eMMC's high-capacity erase size, as to improve the behaviour of the erase operations. We should strive to avoid software configuration options that aren't necessary, but instead deploy common behaviours. For these reasons, let's remove the capability bit for MMC_CAP2_HC_ERASE_SZ and make it the default behaviour. Note that this change doesn't affect eMMCs supporting trim/discard, because these commands operates on sectors and takes precedence over erase commands.
