A number of MMC drivers uses BOUNCE_BUFFER for their DMA buffers. This moves it into Kconfig and performs a step-by-step migration for the affected boards/drivers.
Given that BOUNCE_BUFFER only controls whether the bounce_buffer_* functions are build and linked, this configuration option could be entirely removed and the utility functions built unconditionally. For platforms that don't make use of these functions, the linker will then remove the unused symbols.
I'll leave the final decision if this would be a better implementation (or if this should be done in a two-stage process) to someone else...
Changes in v2: - address sequencing of changes to ensure that tree remains buildable after each individual patch is applied - extended help message in Kconfig to explicitly note that bounce buffers can be used to have properly aligned buffers
Philipp Tomsich (5): Kconfig: Migrate BOUNCE_BUFFER mmc: dw_mmc: depend on BOUNCE_BUFFER mmc: mxsmmc: select BOUNCE_BUFFER unconditionally mmc: tegra: select BOUNCE_BUFFER unconditionally arc: select BOUNCE_BUFFER for CMD_NAND on AXS10x
