| * mpc8xxx_spi: fix SPI support on MPC8308RDBIra W. Snyder2012-09-18-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | The MPC8308RDB Reference Manual states that no bits in the SPMODE register are allowed to change while the enable (EN) bit is set. This driver changes the character length bits (LEN) while the enable (EN) bit is set. Clearing the EN bit while changing the LEN bits makes the driver work correctly on MPC8308RDB.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is based on Linux kernel -next: commit 14f44abf1dafc20ba42ce8616a8fc8fbd1b3712b Author: Brian Norris <computersforpeace@gmail.com> Date: Fri Jul 13 09:28:24 2012 -0700 mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It silently masks off at least one flag that might be set by the driver (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly others. Really, as long as driver writers exercise a small amount of care with NAND_* options, this mask is not necessary at all; it was only here to prevent certain options from accidentally being set by the driver. But the original thought turns out to be a bad idea occasionally. Thus, kill it. Note, this patch fixes some major gpmi-nand breakage.

| * | mmc: detect boot sectors using EXT_CSD_BOOT_MULT tooStephen Warren2012-09-05-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some eMMC devices contain boot partitions, but do not set the PART_SUPPORT bit in EXT_CSD_PARTITIONING_SUPPORT. Allow partition selection on such devices, by enabling partition switching when EXT_CSD_BOOT_MULT is set. Note that the Linux kernel enables access to boot partitions solely based on the value of EXT_CSD_BOOT_MULT; EXT_CSD_PARTITIONING_SUPPORT only influences access to "general" partitions. eMMC devices affected by this issue exist on various NVIDIA Tegra platforms (and presumably many others too), such as Harmony (plug-in eMMC), Seaboard, Springbank, and Whistler (plug-in eMMC).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch takes advantage of the hardware EHCI qTD queuing mechanism to avoid software and transfer splitting overhead so as to make transfers as fast as possible. The only drawback is a call to memalign. However, this is fast compared to the transfer timings, and the heap size to allocate is small, e.g. 128 kiB in the worst case for a transfer length of 65535 packets of 512 bytes. Tested on i.MX25, i.MX35 and i.MX51. In my test conditions, the speed gain was very significant (several times faster), which is really appreciable when accessing large files.

| * | ehci: Fail for multi-transaction interrupt transfersBenoît Thébaudeau2012-09-01-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Interrupt transfers requiring several transactions are not supported by submit_int_msg() because bInterval is ignored. This patch returns a failure code and prints an error message in this case.
