OMAP's hs_mmc driver is used for MMC controller operation on many omap2plus SoCs (OMAP2430, OMAP3, 4, 5 and AM335x). Considering that the device tree entries are already present for these, allow the driver to be built using the config ARCH_OMAP2PLUS rather than individually adding a config for each SoC to enable the support. Use COMPILE_TEST to enable the build for other platforms. Signed-off-by:

Commit 1f6b9fa4 consolidated writes to the STAT register in one location, moving them from omap_hsmmc_do_irq() to omap_hsmmc_irq(). This move has the unwanted side effect that the controller status flags are potentially cleared after a new command has been started as a consequence of reading the previous status flags. This means that if the new command changes the status flags before the IRQ routine returns, those flags may be cleared without handling the event which asserted them, and thus missing the event. Move the writing of the STAT register back in omap_hsmmc_do_irq(), before handling the status flags which generated the interrupt. Signed-off-by:

I'm testing SH-Mobile SDHI driver in DMA mode with a new DMA controller using 'bonnie++' and getting DMA error after which the tmio_mmc_dma.c code falls back to PIO but all commands time out after that. It turned out that the fallback code calls tmio_mmc_enable_dma() with RX/TX channels already freed and pointers to them cleared, so that the function bails out early instead of clearing the DMA bit in the CTL_DMA_ENABLE register. The regression was introduced by commit 162f43e3 (mmc: tmio: fix a deadlock). Moving tmio_mmc_enable_dma() calls to the top of the PIO fallback code in tmio_mmc_start_dma_{rx|tx}() helps.

omap_hsmmc.c depends on <linux/sizes.h> being included indirectly by another header. Once we enable COMPILE_TEST for this driver, we might compile under architectures which won't include <linux/sizes.h> for us. In fact, one such case is x86.
