2013-06-23sf: Update sf to support all sizes of flashesJagannadha Sutradharudu Teki
Updated the spi_flash framework to handle all sizes of flashes using bank/extd addr reg facility The current implementation in spi_flash supports 3-byte address mode due to this up to 16Mbytes amount of flash is able to access for those flashes which has an actual size of > 16MB. As most of the flashes introduces a bank/extd address registers for accessing the flashes in 16Mbytes of banks if the flash size is > 16Mbytes, this new scheme will add the bank selection feature for performing write/erase operations on all flashes.

Currently, the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" can enable the master module of Boot from SRIO and PCIE on a platform. But this is not a silicon feature, it's just a specific booting mode based on the SRIO and PCIE interfaces. So it's inappropriate to put the macro into the file arch/powerpc/include/asm/config_mpc85xx.h. Change the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" to "CONFIG_SRIO_PCIE_BOOT_MASTER", remove them from arch/powerpc/include/asm/config_mpc85xx.h file, and add those macros in configuration header file of each board which can support the master module of Boot from SRIO and PCIE.

In current code FIFO_DEPTH is getting calculated after reading the default FIFOTH register and extracting the RX_WMARK bits from it i.e (RX_WMARK = FIFO_DEPTH/2 -1). Instead of storing the correct value, we were recalculating the FIFO_DEPT each time which is not correct.

2013-06-13fsl_esdhc: Do not clear interrupt status bits until data processedAndrew Gabbasov
After waiting for the command completion event, the interrupt status bits, that occured to be set by that time, are cleared by writing them back. It is supposed, that it should be command related bits (command complete and may be command errors). However, in some cases the DMA already completes by that time before the full transaction completes. The corresponding DINT bit gets set and then cleared before even entering the loop, waiting for data part completion. That waiting loop never gets this bit set, causing the operation to hang. This is reported to happen, for example, for write operation of 1 sector to upper area (block #7400000) of SanDisk Ultra II 8GB card. The solution could be to explicitly clear only command related interrupt status bits. However, since subsequent processing does not rely on any command bits state, it could be easier just to remove clearing of any bits at that point, leaving them all until all data processing completes. After that the whole register will be cleared at once. Also, on occasion, interrupts masking moved to before writing the command, just for the case there should be no chance of interrupt between the first command and interrupts masking.

2013-06-13mmc write bug fixRuud Commandeur
This patch fixes a bug related to mmc writes. When doing fatwrites on an SD-Card, MMC bus problems can occur. Depending on the size of the file, "MMC0: Bus busy timeout!" is reported, resulting in an SD-Card that is no longer responding. It appears to be, that set_cluster can be called with a size being zero. That can be with a file that has a size being an exact multiple (including 0) of the clustersize, but also for files that are smaller than the size of one cluster. The same problem occurs if the "mmc write" command is given with a block count being 0. By adding a check for the block count being zero in mmc_write_blocks (drivers/mmc.c), this problem is solved.

2013-06-12usb: asix: Move software resets to basic_initJulius Werner
The ASIX driver calls a basic_init() function during get_info(), so that not all initialization tasks need to be redone on every init(). Unfortunately, the most important one is still triggered too often: the driver does a full port and MII reset on every asix_init(), requiring up to several seconds to reestablish the link. This patch confines that software reset into the asix_basic_init() function so that it will only be executed once. This saves about a second of boot time on systems using BOOTP. Note: this patch was previously submitted many moons ago as: usb: usbeth: asix: Do a fast init if link already established That patch seens to have been lost or forgotten, so this is a rebased version. It is tested on snow with a Asix USB dongle (Cisco).

The old probe could hang the system under certain conditions (e.g. unconfigured pads). - The read/write/probe functions try to identify unconfigured bus. - Status functions now read irqstatus_raw as per TRM guidelines (except for OMAP243X and OMAP34XX). - Driver now supports up to I2C5 (OMAP5).
