It is necessary to deter the host from sending subsequent DFU_GETSTATUS
request in the case of e.g. writing the buffer to medium.
Here the timeout is increased when we fill up the whole buffer. This delay
allows eMMC memory to perform its internal operations.
Otherwise we end up with HOST's error regarding GET_STATUS receive timeout.

set wMaxPacketSize for full speed descriptors
fs_source_desc, fs_sink_desc to 64.
Full-speed bulk endpoint can have a maximum packet size of
8, 16, 32, or 64 bytes, so choice 64.
The hs_source_desc, hs_sink_desc, already have their wMaxPacketSize
set to 512. That is the only legal value for high speed bulk endpoints.
Strictly speaking, this patch is not needed because
usb_ep_autoconfig will call ep_matches which will
override wMaxPacketSize for BULK endpoints only with
the size associated with the endpoint setup by the udc driver.
But if you want to rely on this, you may as well combine the
full speed descriptor with the high speed descriptor to
minimize confusion.

This commit fixes problems with some non-standard requests send with
device address instead of interface address (bmRequestType.Receipent field).
This happens with dfu-util (debian version: 0.5), which address non standard
requests (like w_value=0x21 and bRequest=GET_DESCRIPTOR) to device.
Without this fix, the above request is STALLED, and hence causes dfu-util
to assume some standard configuration (packet size = 1024B instead of 4096B)
In turn it displays following errors:
Error obtaining DFU functional descriptor
Warning: Assuming DFU version 1.0
Warning: Transfer size can not be detected

Warning: Trying default transfer size 1024
This fix allows passing non-standard request to function setup code, where

This patch adds the support for high speed in usb device framework and usbtty
driver. This feature has been kept within a macro CONFIG_USBD_HS, so the board
configuration files have to define this macro to enable high speed support.
Along with that specific peripheral drivers also need to define a function to
let the framework know that the enumeration has happened at high speed.
This function prototype is "int is_usbd_high_speed(void)"

however as it showed another cases of non-aligned access that previously
worked implicitly. This switches to making sure that all access of
wMaxPacketSize are done via (get|put)_unaligned.
In order to maintain a level of readability to the code in some cases
we now use a variable for the value of wMaxPacketSize and in others, a
macro.

(.27 gadget stack actually has composite drivers).
Signed-off-by: Vitaly Kuzmichev <vkuzmichev@mvista.com>
Disconnecting USB gadget with pending interrupt may cause its wrong
handling in the next time when interface will be started again
(especially actual for RNDIS). This interrupt may force the gadget
to queue unexpected response before setup stage.
Despite the fact that such interrupt handled after dropped pullup
also may add pending response, this will not bring to any issues due to
usb_ep_disable (which clears the queue) called on gadget unregistering.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

After gadget reinitializaton (after tftp has been done once)
packet_received may become equal to 1 due to nuking OUT_EP
while disabling it in eth_reset_config.
rx_submit called from usb_eth_init queues rx_req first time.
But the first call of usb_eth_recv from NetLoop queues rx_req
again due to packet_received = 1.
The following flow shows the path of functions calls when
this happens:
net/net.c:NetLoop

| ether.c:usb_eth_init
