2013-07-29usb: mv_udc: Add bounce bufferMarek Vasut
The requests sent to the controller are not properly cache aligned most of the time, thus implement a simple bounce buffer to avoid problem with cache.

2013-07-29usb: mv_udc: Add proper cache managementMarek Vasut
Implement functions to flush/invalidate dcache over QH and qTDs and make use of them where appropriate. Also use them to replace the old incorrect cache management attempt. This is the first step towards making this driver work with data cache enabled.

2013-07-29usb: mv_udc: Implement better qTD item accessorMarek Vasut
The code for retrieving qTD item for particular endpoint is hard to understand, moreover it's duplicated all over the driver. Move the code into single nice and documented function.

2013-07-29usb: mv_udc: Improve allocation of qTD itemsMarek Vasut
Allocate the qTD items all at once instead of allocating them separately. Moreover, make sure each qTD is properly aligned to 32-bytes boundary and that cache can be safely flushed over each qTD touple.

2013-07-29usb: mv_udc: Properly align the endpoint QH and qTD listMarek Vasut
The endpoint QH list has to be aligned to 10-bit boundary. We also have to make sure the list is aligned on a cacheline boundary. Make sure it is. Furthermore, check if the memory allocation for the QH list didn't fail. Moveover, improve the comment about the QH list structure. Finally, the qTD item list has to be aligned only to 5-bit boundary, not 10-bit as it is now, fix this as well.

2013-07-29usb: mv_udc: Clean up the initial variable checkMarek Vasut
Clean up the code that checks the validity of a USB gadget driver in usb_gadget_register_driver(). Moreover, limit the speed of the driver to either FULL or HIGH, this is more precise and once we have xHCI support, also more correct.

2013-07-29usb: mv_udc: Make use of struct ehci_ctrlMarek Vasut
The usb_lowlevel_init() call already fills and passes back struct ehci_ctrl , which readily contains correctly determined address of the port register block address computed from values from controller configuration registers. Leverage this and make use of this value as this makes the code mode universal, but also gets us rid of the CONFIG_USB_REG_BASE configuration option. Moreover, this patch cleans up the usb_gadget_register_driver() call a little by correcting the error handling. Note the usb_lowlevel_init() and mvudc_probe() are now called in reversed order, but this has no impact on the code.

2013-07-29usb: ehci: Split out struct ehci_ctrl definitionMarek Vasut

2013-07-29usb: mv_udc: Clean up the EP initializationMarek Vasut
Move the constant values that are programmed into mv_ep.ep into separate static const structure so they can be memcpy()'d when the initialization happens. Moveover, we only every init NUM_ENDPOINTS, not 2 * NUM_ENDPOINTS, so fix this bug as well.

2013-07-29usb: mv_udc: Move endpoint array into driver dataMarek Vasut

2013-07-25powerpc/ppc4xx: Remove CONFIG_SYS_FLASH_PROTECTION from gdsys boardsDirk Eibach
CONFIG_SYS_FLASH_PROTECTION was active on most gdsys boards by default, while hardware flash protection was not implemented. Hardware support was added recently and we get into trouble because backward compatibility is broken (u-boot can't unprotect the protected flash after a downgrade). So we decided to disable hardware flash protection for all our boards. Signed-off-by: Dirk Eibach <dirk.eibach@gdsys.cc> Signed-off-by: Stefan Roese <sr@denx.de>

2013-07-25cfi_flash: use buffer length in unmap_physmem()Kuo-Jung Su
While the flash_detect_legacy() of drivers/mtd/cfi_flash.c feed unmap_physmem() with MAP_NOCACHE as 2nd parameter, the do_spi_flash_read_write() of common/cmd_sf.c feed unmap_physmem() with the length of the mapped buffer as 2nd parameter. It's apparently a bug, and I personally think the 2nd parameter should be the length of the mapped buffer.
