mmc: Add MMC_PROGRESS_*

2011-03-24T16:24:57Z

This is my second attempt to make this enum generally available. The first attempt added MMCIF_PROGRESS_* to include/linux/mmc/sh_mmcif.h. However this is not sufficiently generic as the enum will be used by SDHI boot code. Signed-off-by: Simon Horman Signed-off-by: Paul Mundt

mmc: sh_mmcif: Convert to __raw_xxx() I/O accessors.

2011-01-14T06:57:47Z

When using the I/O accessors in raw mode from the boot stubs we don't want to bother with any of the complexity associated with readl/writel and friends. Furthermore, utilization within the context of the host driver itself is all performed on an ioremapped window, so using the __raw variants there doesn't pose any problem either. If and when barriers need to be added in the future, these will need to be explicitly written out, but this is so far not a concern for any of the affected CPUs in question. This fixes up the link error introduced by the ARM tree via its barrier refactoring: arch/arm/boot/compressed/mmcif-sh7372.o: In function `mmcif_loader': mmcif-sh7372.c:(.text+0x9e8): undefined reference to `outer_cache Following the change in: http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=6275/1 Reported-by: Simon Horman Signed-off-by: Paul Mundt

Merge branches 'sh/memchunk' and 'common/mmcif' into sh-latest

mmc, sh: Remove sh_mmcif_boot_slurp()

2010-12-08T07:24:28Z

As the only caller of sh_mmcif_boot_do_read() is sh_mmcif_boot_slurp() the configuration portion of sh_mmcif_boot_slurp() can be merged into sh_mmcif_boot_do_read(). Once this is done sh_mmcif_boot_slurp() is only a call to sh_mmcif_boot_do_read() with platform specific information - the offset that images are stored on MMC. So make the sh_mmcif_boot_do_read() call directly from platform code and remove sh_mmcif_boot_slurp() altogether. Cc: Magnus Damm Signed-off-by: Simon Horman Signed-off-by: Paul Mundt

mmc, sh: Move MMCIF_PROGRESS_* into sh_mmcif.h

Allow MMCIF_PROGRESS_* to be shared. Cc: Magnus Damm Signed-off-by: Simon Horman Signed-off-by: Paul Mundt

sh, mmc: Use defines when setting CE_CLK_CTRL

2010-11-29T03:54:55Z

The 16-19th bits of CE_CLK_CTRL set the MMC clock frequency. Cc: Yusuke Goda Cc: Magnus Damm Signed-off-by: Simon Horman Signed-off-by: Paul Mundt

mmc, sh: Correct value for reset

2010-11-29T03:54:50Z

This resolves a regression that I introduced in "mmc, sh: Move constants to sh_mmcif.h". Having examined the manual and tested the code on an AP4EVB board it seems that the correct sequence is. 1) Write 1 to bit 31 and zeros to all other bits 2) Write zero to all bits Cc: Yusuke Goda Cc: Magnus Damm Signed-off-by: Simon Horman Signed-off-by: Paul Mundt

mmc: sh_mmcif: add DMA support

2010-11-25T07:26:46Z

The MMCIF controller on sh-mobile platforms can use the DMA controller for data transfers. Interface to the SH dmaengine driver to enable DMA. We also have to lower the maximum number of segments to match with the number od DMA descriptors on SuperH, this doesn't significantly affect driver's PIO performance.

mmc, sh: Move constants to sh_mmcif.h

2010-11-10T09:25:10Z

This moves some constants from sh_mmcif.c to sh_mmcif.h so that they can be used in sh_mmcif_boot_init(). It also alters the definition of SOFT_RST_OFF from (0 << 31) to ~SOFT_RST_ON (= ~(1 << 31)). The former seems bogus. The latter is consistent with the code in sh_mmcif_boot_init(). Cc: Yusuke Goda Cc: Magnus Damm Signed-off-by: Simon Horman Signed-off-by: Paul Mundt
