powerpc/srio-pcie-boot: Avoid the NOR_BOOT macro when boot from SRIO/PCIE
When a board (slave) boots from SRIO/PCIE, it would get the instructions
from a remote board (master) by SRIO/PCIE interface, and the slave's
u-boot image should be built with the
SYS_TEXT_BASE=0xFFF80000;
So the u-boot of the slave should avoid the NOR_BOOT branch at the
booting stage.
For example, when a P2041RDB boots from SRIO/PCIE, it will set TLB
entry 15 from base address "CONFIG_SYS_MONITOR_BASE & 0xffc00000",
and with the 4M size as the boot window in NOR_BOOT branch. Because
the CONFIG_SYS_MONITOR_BASE = CONFIG_SYS_TEXT_BASE = 0xFFF80000, so
the TLB entry will be from base address 0xffc00000 and with 4M size.
Then the u-boot will set TLB entry 14 from base address
"CONFIG_SYS_INIT_RAM_ADDR", and with the 16K size as the initial
stack window. For the P2041RDB platform, the CONFIG_SYS_INIT_RAM_ADDR
= 0xffd00000. So the TLB entry 14 and 15 will be in confliction.
There will be right TLB entries configurations when avoid the
NOR_BOOT branch and set the boot window from 0xfff00000 with 1M

i660: USBHOST Configured In Smart-Idle Can Lead To a Deadlock
On OMAP4/5, soft-resetting the UHH module can put it into
Smart-Idle mode and lead to a deadlock.
On OMAP3 this doesn't seem to be the case but still instabilities
are observed on beagle (3530 ES1.0) if soft-reset is used.
e.g. NFS root failures with Linux kernel.
dfu: Implementation of target reset after communication with dfu-util's -R switch
This patch extends dfu code to support transmission with -R switch
specified at dfu-util.
When -R is specified, the extra USB_REQ_DFU_DETACH request is sent after
successful data transmission. Then dfu resources are released and reset
command is issued.

usb: mv_udc: Add bounce buffer
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.

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

usb: mv_udc: Properly align the endpoint QH and qTD list
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.

usb: mv_udc: Make use of struct ehci_ctrl
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.
