From 2acc24fc28ef782f4baef1aa0193d520ee9610b9 Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Fri, 30 Nov 2018 22:13:25 +0100 Subject: Kconfig: Migrate BOUNCE_BUFFER The bounce buffer is used by a few drivers (most of the MMC drivers) to overcome limitations in their respective DMA implementation. This moves the configuration to Kconfig and makes it user-selectable (even though it will be a required feature to make those drivers work): the expected usage is for drivers depending on this to 'select' it unconditionally from their respective Kconfig (see follow-up patches). This commit includes a full migration using moveconfig.py to ensure that each commit compiles. To ensure bisectability we update dependencies of various drivers to now select BOUNCE_BUFFER when needed.
