2011-11-03tegra2: Move MMC clock initialization into MMC driverStephen Warren
This centralizes knowledge of MMC clocking into the MMC driver. This also removes clock setup from the board files, which will simplify later changes that modify the Harmony board to support the correct set of MMC controllers.

2011-11-03mmc: CMD7:MMC_CMD_SELECT_CARD response fixAjay Bhargav
As per JEDEC document JESD84-A441 (page 105) response for CMD7 (MMC_CMD_SELECT_CARD) response should be R1 instead of R1b. In uboot we never take MMC to disconnected state and on powerup its always ideal state which later goes to stand-by state. from document footnote: R1 while selecting from Stand-By State to Transfer State; R1b while selecting from Disconnected State to Programming State.

2011-11-03mmc: mv_sdhci: fix 8bus width access for 88SV331xV5Lei Wen
Marvell 88SV331xV5 platform's sdhci host control is not very standard with the spec in the 8bit handling. It need to set its private register to switch to the 8bit mode which is not included in the standard sdhci registers. This patch mainly hacks the writeb method, and set its private register if it find the driver is going to switch to the 8bit mode. Signed-off-by: Lei Wen <leiwen@marvell.com>

2011-09-03mmc: S5P: Support DMA restarts at buffer boundariesAnton Staaf
Currently if a DMA buffer straddles a buffer alignment boundary (512KiB) then the DMA engine will pause and generate a DMA interrupt. Since the DMA interrupt is not enabled it will hang the MMC driver. This patch adds support for restarting the DMA transfer. The SYSTEM_ADDRESS register contains the next address that would have been read/written when a boundary is hit. So we can read that and write it back. The write triggers the resumption of the transfer.

2011-07-15mmc: Access mode validation for eMMC cards > 2 GiBŁukasz Majewski
This patch provides handling of the two way handshake when SEND_OP_COND (CMD1) is send to mmc card. It is necessary to inform eMMC card if the host can work with high capacity cards (Jedec JESD84-A441, point 7.4.3). The extra flag MMC_MODE_HC (high capacity) is added to indicate if the host is capable of handling the high capacity eMMC cards. Since this change is added to the generic mmc framework, then it requires other boards to indicate if their mmc controllers can handle high capacity cards. As it is now - the old behaviour of the framework is preserved. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
