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. In doing so, it turns out that a few boards/configs enabled CONFIG_BOUNCE_BUFFER in their config headers without an apparent need. The migration (using moveconfig) for those boards is kept in a separate patch, so it can be more easily reviewed by the affected parties to make a determination whether it is actually needed. 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... END.
I think this is a good idea, but I get build errors after applying patch 2/6 since CONFIG_BOUNCE_BUFFER is now enabled via Kconfig and defined as 1 while at the same time it is just defined (but to nothing) in socfpga_common.h.
Can you change or reorder this series so that every commit compiles? Regards, Simon
