The EHCI controller has some very specific requirements for the USB 2.0
port test modes, which were not closely followed in the initial test
mode commit. It demands that the host controller is completely shut down
(all ports suspended, Run/Stop bit unset) when activating test mode, and
will not work on an already enumerated port.
This patch fixes that by introducing a new ehci_shutdown() function that
closely follows the procedure listed in EHCI 4.14. Also, when we have
such a function anyway, we might as well also use it in
usb_lowlevel_stop() to make the normal host controller shutdown cleaner.

DFU spec mentions it as a method to upgrade firmware (software stored
in writable non-volatile memory). It also says other potential uses of
DFU is beyond scope of the spec.
Here such a beyond the scope use is being attempted - directly pumping
binary images from host via USB to RAM. This facility is a developer
centric one in that it gives advantage over upgrading non-volatile
memory for testing new images every time during development and/or
testing.
Directly putting image onto RAM would speed up upgrade process. This and
convenience was the initial thoughts that led to doing this, speed
improvement over MMC was only 1 second though - 6 sec on RAM as opposed
to 7 sec on MMC in beagle bone, perhaps enabling cache and/or optimizing
DFU framework to avoid multiple copy for ram (if worth) may help, and
on other platforms and other boot media like NAND maybe improvement
would be higher.
And for a platform that doesn't yet have proper DFU suppport for
non-volatile media's, DFU to RAM can be used.
Another minor advantage would be to increase life of mmc/nand as it
would be less used during development/testing.
usage: <image name> ram <start address> <size>
eg. kernel ram 0x81000000 0x1000000
Downloading images to RAM using DFU is not something new, this is
acheived in openmoko also.
DFU on RAM can be used for extracting RAM contents to host using dfu
upload. Perhaps this can be extended to io for squeezing out register
dump through usb, if it is worth.

The patch fixes the improper read and write of sdhci
host control register for sdma transfer.
The problem comes when reading and writing 1 byte long

the value of the next registers which are in 4 bytes boundary.
This patch replaces four byte register read/write functions

In dwmci_prepare_data, the descriptors are allocated for DMA transfer.
These are allocated using the ALLOC_CACHE_ALIGN_BUFFER. This macro uses
the stack to allocate these descriptors. This becomes a problem if the
DMA transfer continues after the processor leaves the function in which
the descriptors were allocated.
Therefore, I have moved the allocated of the buffers up one level, to
dwmci_send_cmd(). The DMA transfer should be complete when leaving this
function.

"mmc_send_cmd: timeout: No status update" error sometimes happens in
omap_hsmmc driver func mmc_send_cmd() when the MMC controller card
identification and selection sequence is executed for eMMC on OMAP4
boards.
It happens due to incorrect execution of CMD line reset procedure
for OMAP4. Because CMD(DAT) lines reset procedures are slightly
different for OMAP3 and OMAP4(AM335x,OMAP5,DRA7xx).
According to OMAP3 TRM:
Set SRC(SRD) bit in MMCHS_SYSCTL register to 0x1 and wait until
it returns to 0x0.
According to OMAP4(AM335x,OMAP5,DRA7xx) TRMs, CMD(DATA) lines reset
procedure steps must be as follows:
1. Initiate CMD(DAT) line reset by writing 0x1 to SRC(SRD) bit in
MMCHS_SYSCTL register (SD_SYSCTL for AM335x).
2. Poll the SRC(SRD) bit until it is set to 0x1.
3. Wait until the SRC(SRD) bit returns to 0x0
(reset procedure is completed).
Unfortunately, at present omap_hsmmc driver has support only for
OMAP3. And as result step #2 is missing for OMAP4(AM335x,OMAP5,DRA7xx).
This sometimes leads to the fact that the waiting loop which is
required in step #3 does not executed, because SRC bit does not set
yet (at the moment of checking a condition of a loop execution).
And as a result this can cause to timeout error when sending a
next command.
In the particular case (working with eMMC witch do not respond to
some SD specific command) due to incorrect reset sequence after
command SD_CMD_SEND_IF_COND which finished with CTO flag within
64 clock cycles, the next command MMC_CMD_APP_CMD leads to a
timeout error within 1s.
So, extend CMD(DATA) lines reset procedure in func
mmc_reset_controller_fsm() by adding the missing step #2 for
OMAP4+/AM335x boards.
