This is the USB host controller used on the Altera SoCFPGA and Raspbery Pi.
This code has three checkpatch warnings, but to make sure it stays at least
readable and clear, these are not fixed. These bugs are in the USB request
handling combinatorial logic, so any abstracting of those is out of question.
Tested on DENX MCV (Altera SoCFPGA 5CSFXC6C6U23C8N) and RPi B+ (BCM2835).

Without NULL termination, various commands will read past the
end of input. In particular, this was noticed with error()
calls in cb_getvar and simple_strtoul() in cb_download.
Since the download callback happens elsewhere, the 4k buffer
should always be sufficient to handle command arguments.

This bit allows the MUSB controller to negotiate for high-speed mode when
the device is reset by the hub. If unset, Babble errors occur with
high-speed mass storage devices right after the first packet. This condition
is not caught by the interrupt handles in U-Boot, so no recovery is done,
and the USB communication is stuck.
To fix this, set the bit unconditionally, not only for
CONFIG_USB_GADGET_DUALSPEED but also for host-only modes.

When we first start an int queue, the qh's overlay area is all zeros. This
gets filled by the hc with the actual qtd values as soon as it advances
the queue, but we may call poll_int_queue before then, in which case we
would think the transfer has completed as the hc has not yet copied the
qt_token to the overlay, so the active flag is not set.
This fixes this by checking the actual qtd token, rather then the overlay.
This also fixes a (theoretical) race where we see the completion in the
overlay and free and re-use the qtd before the hc has completed writing back
the overlay to the actual qtd.

This commit provides distinction between DFU device detach and reset.
The -R behavior is preserved with proper handling of the dfu-util's -e
switch, which detach the DFU device.
By running dfu-util -e; one can force device to finish the execution of
dfu command on target and execute some other scripted commands.
Moreover, some naming has been changed - the dfu_reset() method now is known
as dfu_detach(). New name better reflects the purpose of the code.
It was also necessary to increase the number of usb_gadget_handle_interrupts()
calls since we also must wait for detection of the USB reset event.
Example usage:
1. -e (detach) switch
dfu-util -a0 -D file1.bin;dfu-util -a3 -D uImage;dfu-util -e
access to u-boot prompt.
2. -R (reset) switch
dfu-util -a0 -D file1.bin;dfu-util -R -a3 -D uImage

CONFIG_SYS_DFU_DATA_BUF_SIZE may be large to allow for FAT/ext layouts
to transfer large files. However, this means that individual write
operations will take a long time. Allow backends to specify a maximum
buffer size, so that each write operation is limited to a smaller data
block. This prevents the DFU protocol from timing out when e.g. writing
to SPI flash. I would guess that NAND might benefit from setting this
value too, but I can't test that.
Signed-off-by: Stephen Warren <swarren@nvidia.com>
Fix calls to dfu_write() and dfu_flush() to detect errors in the I/O
itself. This could happen due to problems with the storage medium, or
simply when trying to write a FAT/ext file that is larger than the buffer
dfu_mmc.c maintains for this purpose.
Signal the error by switching the DFU state/status. This will be picked
up by the DFU client when it sends the next DFU request. Note that errors
can't simply be returned from e.g. dnload_request_complete(), since that
function has no way to pass errors back to the DFU client; a call to
dnload_request_complete() simply means that a USB OUT completed.
This error state/status needs to be cleared when the next DFU client
connects. While there is a DFU_CLRSTATUS request, no DFU client seems to
send this. Hence, clear this when selecting the USB alternate setting on
the USB interface.
Finally, dfu.c relies on a call to dfu_flush() to clear up the internal
state of the write transaction. Now that errors in dfu_write() are
detected, dfu_flush() may no longer be called for every transaction.
Separate out the cleanup code into a new function, and call it whenever
dfu_write() fails, as well as from any call to dfu_flush().

struct ci_req is a purely software structure, and needs no specific

There's no need to store an array of QTD pointers in the controller.
Since the calculation is so simple, just have ci_get_qtd() perform it
at run-time, rather than pre-calculating everything.
Signed-off-by: Stephen Warren <swarren@nvidia.com>
2 QTDs are allocated for each EP. The current allocation scheme aligns
the first QTD in each pair, but simply adds the struct size to calculate
the second QTD's address. This will result in a non-cache-aligned
addresss IF the system's ARCH_DMA_MINALIGN is not 32 bytes (i.e. the
size of struct ept_queue_item).
Similarly, the original ilist_ent_sz calculation aligned the value to
ARCH_DMA_MINALIGN but didn't take the USB HW's 32-byte alignment
requirement into account. This doesn't cause a practical issue unless
ARCH_DMA_MINALIGN < 32 (which I suspect is quite unlikely), but we may
as well fix the code to be explicit, so it's obviously completely
correct.
The new value of ILIST_ENT_SZ takes all alignment requirements into
account, so we can simplify ci_{flush,invalidate}_qtd() by simply using
that macro rather than calling roundup().
Similarly, the calculation of controller.items[i] can be simplified,
since each QTD is evenly spaced at its individual alignment requirement,
rather than each pair being aligned, and entries within the pair being
spaced apart only by structure size.

This will allow functions other than ci_udc_probe() to make use of the
constants in a future change.
This in turn requires converting the const int variables to #defines,
since the initialization of one global const int can't depend on the
value of another const int; the compiler thinks it's non-constant if
that dependency exists.

Fix ci_ep_submit_next_request()'s ZLP transmission code to explicitly
