[U-Boot] [PATCH] mmc:sdhci:fix: Change default interrupts enabled at SDHCI initialization
by Lukasz Majewski 12 Mar '13

12 Mar '13

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(a)samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park(a)samsung.com> Cc: Lei Wen <leiwen(a)marvell.com> Cc: Andy Fleming <afleming(a)freescale.com> --- drivers/mmc/sdhci.c | 8 +++++--- 1 files changed, 5 insertions(+), 3 deletions(-) diff --git a/drivers/mmc/sdhci.c b/drivers/mmc/sdhci.c index 0fd1337..76c14fb 100644 --- a/drivers/mmc/sdhci.c +++ b/drivers/mmc/sdhci.c @@ -412,9 +412,11 @@ int sdhci_init(struct mmc *mmc) status = sdhci_readl(host, SDHCI_PRESENT_STATE); } - /* Eable all state */ - sdhci_writel(host, SDHCI_INT_ALL_MASK, SDHCI_INT_ENABLE); - sdhci_writel(host, SDHCI_INT_ALL_MASK, SDHCI_SIGNAL_ENABLE); + /* Enable only interrupts served by the SD controller */ + sdhci_writel(host, SDHCI_INT_DATA_MASK | SDHCI_INT_CMD_MASK + , SDHCI_INT_ENABLE); + /* Mask all sdhci interrupt sources */ + sdhci_writel(host, 0x0, SDHCI_SIGNAL_ENABLE); return 0; } -- 1.7.2.3

[U-Boot] [PATCH] I2C: S3C24X0: Bug fixes in i2c_transfer
by Rajeshwari Shinde 12 Mar '13

12 Mar '13

This patch corrects the following issues 1) Write the correct M/T Stop value to I2CSTAT after i2c write. According to the spec, after finish the data transmission, we should write a M/T Stop (I2C_MODE_MT | I2C_TXRX_ENA) to I2CSTAT instead of a M/R Stop (I2C_MODE_MR | I2C_TXRX_ENA). 2) Not split the write to I2CSTAT into 2 steps in i2c read. According to the spec, we should write the combined M/R Start value to I2CSTAT after setting the slave address to I2CDS 3) Fix the mistake of making an equality check to an assignment. In the case of I2C write with the zero-length address, while tranfering the data, it should be an equality check (==) instead of an assignment (=).

[U-Boot] [PATCH] at91sam9x5: mmc: save environment as a file in FAT partition.

11 Mar '13

This patch will save U-Boot environment as a file: uboot.env, in FAT partition instead of saving it in raw sector of SD card. Since saving environment in raw sector has risk of corrupting the SD card and only can use very small size. Save as a FAT file has no above limitation.
