2012-07-07st_smi: Fix smi read statusVipin Kumar
smi_read_sr fails sometimes because of TFF not getting set within assumed time. This condition may arise because of, for example, smi memory being in a erase mode. This fix is to enable reading the status register until timeout. Signed-off-by: Vipin Kumar <vipin.kumar@st.com> Signed-off-by: Amit Virdi <amit.virdi@st.com> Signed-off-by: Stefan Roese <sr@denx.de>

2012-07-07st_smi: Read status until timeout happensVipin KUMAR
SMI driver read status fails because the control register could not be overwritten. Instead, the read status should be tried until timeout. Signed-off-by: Vipin Kumar <vipin.kumar@st.com> Signed-off-by: Amit Virdi <amit.virdi@st.com> Signed-off-by: Stefan Roese <sr@denx.de>

2012-07-07st_smi: Add support for SPEAr SMI driverVipin KUMAR
SMI is the serial memory interface controller provided by ST. Earlier, a driver exists in the u-boot source code for the SMI IP. However, it was specific to spear platforms. This commit converts the same driver to a more generic driver. As a result, the driver files are renamed to st_smi.c and st_smi.h and moved into drivers/mtd folder for reusability by other platforms using smi controller peripheral.

These two function nows ensure that the MPP is configured correctly for the SPI controller before any SPI access, and restore the initial configuration when the access is over.

2012-07-07Revert "I2C: OMAP: detect more devices when probing an i2c bus"Tom Rini
This reverts commit 0e57968a215d1b9d271f3fa5bebeddeaea0c8075. The short version of the original commit is that some i2c devices cannot be probed via read as they NAK the first cycle, so try and probe via a write that we abort before it writes to the device. This however is not allowed by the TRM for any of these parts. The section on I2C_CON (table 17-35 I2C_CON for am/dm37x for example) says you must not change the register while STT has been set. On these parts, the unpredictable behavior that the chip exhibits is not problematic. On OMAP4 however it results in the chip being in a bad state: Panda # i2c probe Valid chip addresses: 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 30 31 32 33 34 35 36 37 38 39 3A 3B 3C 3D 3E 3F 40 41 42 43 44 45 46 47 48 49 4A 4B 4C 4D 4E 4F 50 51 52 53 54 55 56 57 58 59 5A 5B 5C 5D 5E 5F 60 61 62 63 64 65 66 67 68 69 6A 6B 6C 6D 6E 6F 70 71 72 73 74 75 76 77 78 79 7A 7B 7C 7D 7E 7F Panda # i2c md 50 0 timed out in wait_for_pin: I2C_STAT=0 I2C read: I/O error Error reading the chip.
