[U-Boot] [PATCH v2 0/5] Migrate BOUNCE_BUFFER

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
