mmc: sdhci.c: Add config option to use a fixed buffer for transfers While implementing SDIO/MMC SPL booting for the Marvell Armada 38x, the following problem occured. The SPL runs in internal SRAM which is the L2 cache locked to memory. When the MMC buffers now are located on the stack (or bss), the SDIO controller (SDHCI) can't write into this L2 cache memory. This patch introduces a method to use a fixed buffer that will be used for all transfers by defining CONFIG_FIXED_SDHCI_ALIGNED_BUFFER. This way, the board can use this buffer address located in SDRAM for all transfers. This solves this SPL problem on the A38x and should only be used in the SPL U-Boot version. Tested for SPL booting on Marvell Armada 38x DB-88F6820-GP board.

Fix wrong sdhci host control register read and write The patch fixes the improper read and write of sdhci host control register for sdma transfer. The problem comes when reading and writing 1 byte long host control register with the sdhci_readl() and sdhci_writel(). The misuse of these functions overwrite the value of the next registers which are in 4 bytes boundary. This patch replaces four byte register read/write functions with one byte read/write ones.

mmc: Split mmc struct, rework mmc initialization (v2) The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long. Changes since v1: * Use calloc instead of manually calling memset. * Mark mmc_register as deprecated. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>

mmc: sdhci.c: Add config option to use a fixed buffer for transfers While implementing SDIO/MMC SPL booting for the Marvell Armada 38x, the following problem occured. The SPL runs in internal SRAM which is the L2 cache locked to memory. When the MMC buffers now are located on the stack (or bss), the SDIO controller (SDHCI) can't write into this L2 cache memory. This patch introduces a method to use a fixed buffer that will be used for all transfers by defining CONFIG_FIXED_SDHCI_ALIGNED_BUFFER. This way, the board can use this buffer address located in SDRAM for all transfers. This solves this SPL problem on the A38x and should only be used in the SPL U-Boot version. Tested for SPL booting on Marvell Armada 38x DB-88F6820-GP board.

mmc: sdhci: fix bus width switching on Samsung SoCs Fix bus width switching from 8-bit mode down to 4-bit or 1-bit modes on Samsung SoCs using SDHCI_QUIRK_USE_WIDE8. These SoCs report controller version 2.0 yet they support 8-bit bus widths. If 8-bit mode was previously enabled and then an operation like "mmc dev" caused a switch back down to 4-bit or 1-bit mode, WIDE8 was left set, causing failures. This problem was manifested by "mmc dev" timing out. Signed-off-by: Matt Reimer <mreimer@sdgsystems.com>

mmc:sdhci:fix: Change default interrupts enabled at SDHCI initialization This patch changes sdhci_init()'s behavior to NOT enable all interrupt sources by default. Moreover interrupt signaling has been disabled. This patch do not enable interrupts which aren't served in u-boot (they are defined at sdhci.h but NOT used elsewhere): - SDHCI_INT_CARD_INSERT, SDHCI_INT_CARD_REMOVE, SDHCI_BUS_POWER, SDHCI_INT_CARD_REMOVE, SDHCI_INT_CARD_INT Special care shall be put on SDHCI_INT_CARD_INT, which indicates interrupt generated by SD card. According to "SD Host Controller Simplified Spec. ver 3.00" when bit 8 (Card Interrupt Status Enable) at "Normal Interrupt Status Enable Register" (offset 0x34) is set, the card interrupt detection is started. Then eMMC card may cause the SD controller to set this bit and then this interrupt is passed to booted OS and might cause kernel crash. To sum up: - Only enable interrupts, which are served at u-boot - This cleanup as a side effect fixes SDHCI's CARD INTERRUPT problem at Linux kernel (versions 3.6+, sdhci controller) - Keep masked bits at "Normal Interrupt Signal Enable Register" (0x38h) Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Cc: Lei Wen <leiwen@marvell.com> Cc: Andy Fleming <afleming@freescale.com> Acked-by: Jaehoon Chung <jh80.chung@samsung.com> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
