d3e0747846 usb: ehci: add missing cache managment
Commit 8f62ca6 "usb: ehci: Support interrupt transfers via periodic list"
didn't include any cache management in the new interrupt transfer path.
It also added an extra write to or_asynclistaddr in usb_lowlevel_init(),
without having flushed out the data there.

Add the missing cache management calls, so that the code works again.

This allows the USB keyboard on Tegra's Seaboard/Springbank boards to
work.

e82a316d7f usb: ehci: add Faraday USB 2.0 EHCI support
This patch adds support to both Faraday FUSBH200 and FOTG210,
the differences between Faraday EHCI and standard EHCI are
listed bellow:

1. The PORTSC starts at 0x30 instead of 0x44.
2. The CONFIGFLAG(0x40) is not only un-implemented, and
   also has its address space removed.
3. Faraday EHCI is a TDI design, but it doesn't
   compatible with the general TDI implementation
   found at both U-Boot and Linux.
4. The ISOC descriptors differ from standard EHCI in
   several ways. But since U-boot doesn't support ISOC,
   we don't have to worry about that.

1dde1423ad usb: ehci: add weak-aliased function for PORTSC
There is at least one non-EHCI compliant controller (i.e. Faraday EHCI)
not only leave RESERVED and CONFIGFLAG registers un-implemented
but also has their address spaces removed.

As an result, the PORTSC register of Faraday EHCI always
starts from 0x30 instead of 0x44 in standard EHCI.

So that we'll need a weak-aliased function for abstraction.

9c6a9d7c8b usb: ehci: prevent bad PORTSC register access
1. The 'index' of ehci_submit_root() is not always > 0.

   e.g.
   While it gets invoked from usb_get_descriptor(),
   the 'index' is always a '0'. (See ch.9 of USB2.0)

2. The PORTSC register is not always required, and thus it
   should only report a port error when necessary.
   It would cause a port scan failure if the ehci_submit_root()
   always gets terminated by a port error.

4edcf0a3df usb: asix: Move software resets to basic_init
The ASIX driver calls a basic_init() function during get_info(), so that
not all initialization tasks need to be redone on every init().
Unfortunately, the most important one is still triggered too often: the
driver does a full port and MII reset on every asix_init(), requiring up
to several seconds to reestablish the link.

This patch confines that software reset into the asix_basic_init()
function so that it will only be executed once. This saves about a
second of boot time on systems using BOOTP.

Note: this patch was previously submitted many moons ago as:

   usb: usbeth: asix: Do a fast init if link already established

That patch seens to have been lost or forgotten, so this is a rebased
version. It is tested on snow with a Asix USB dongle (Cisco).

ed10e66aba usb: Correct CLEAR_FEATURE code in ehci-hcd
This commit broke USB2 on link (Chromebook Pixel):

  020bbcb usb: hub: Power-cycle on root-hub ports

However the root cause seems to be a missing mask and missing 'break'
in ehci-hcd.c. This patch fixes both.

On link, 'usb start' with a USB keyboard and memory stick inserted now
finds both. The keyboard works as expected. Also ext2ls shows a directory
listing from the memory stick.

If CONFIG_USB_DEV_PULLUP_GPIO is defined, a link error occurs because the
set_GPIO_mode() helper function is not implemented.  This function doesn't do
much except make the code a little more readable, so I just manually coded its
equivalent and removed the prototype from the header file.  It is invoked no
where else in the code.

While I was at it, I noticed that two other function prototypes in the same
header file are also neither implemented nor invoked anywhere, so I removed them
as well.

4de602f2b0 musb: am335x: disable bulk split-combine feature
On TI AM335x devices, MUSB has bulk split/combine feature enabled
in the ConfigData register, but the current MUSB driver does not
support it yet. Therefore, disable the feature for now, until the
driver adds the support.

One usecase which is broken because of this feature is that Ether
gadget stops working in Fullspeed mode (by un-defining
CONFIG_USB_GADGET_DUALSPEED)

After desabled this feature, MUSB driver send packets in proper size
(no more than 64 bytes) in Fullspeed mode.

This has been validated with Ether gadget in Fullspeed mode on AM335x
EVM.

f7b4162eb1 usb:composite:fix Provide function data when addressing device with only one interface
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
it shall be handled.

833a53c627 musb-new: am35x backend driver
Backend driver for MUSB OTG controllers found on TI AM35x.

It seems that on AM35X interrupt status registers can be updated
_before_ core registers. As we don't use true interrupts in U-Boot
and poll interrupt status registers instead this can result in
interrupt handler being called with non-updated core registers.
This confuses the code and result in hanged transfers.
Add a small delay in am35x_interrupt as a workaround.

Existing U-Boot musb driver has no support for the new gadget framework
and also seems to have other limitations. As gadget framework is ported
from Linux it seems pretty natural to port musb gadget driver as well.

This driver supports both host and peripheral modes.

This is not a replacement for current musb driver (at least now) as
there are still some consumers of the old UDC interface.

No DMA operation support included, CONFIG_MUSB_PIO_ONLY should be
defined.

Virtual root hub device is not implemented.

c60795f41d usb: use linux/usb/ch9.h instead of usbdescriptors.h
Linux usb/ch9.h seems to have all the same information (and more)
as usbdescriptors.h so use the former instead of the later one.

As a consequense of this change USB_SPEED_* values don't correspond
directly to EHCI speed encoding anymore, I've added necessary
recoding in EHCI driver. Also there is no point to put speed into
pipe anymore so it's removed and a bunch of host drivers fixed to
look at usb_device->speed instead.

Old usbdescriptors.h included is not removed as it seems to be
used by old USB device code.

This makes usb.h and usbdevice.h incompatible. Fortunately the
only place that tries to include both are the old MUSB code and
it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute
on musb_regs structure but this attribute seems to be unneeded
(old MUSB code doesn't support any DMA at all).

1. The packet length check has to be adjusted, as all ASIX chips
only use 11 bits to indicate the length. AX88772B uses the other
bits to indicate unrelated things, which cause the check to fail.
This fix is based on a fix for the Linux kernel by Marek Vasut.
Linux upstream commit: bca0beb9363f8487ac902931a50eb00180a2d14a

2. AX88772B provides several bulk endpoints. Only the first
IN/OUT endpoints work in the default configuration. So stop
enumeration after we found them to avoid overwriting the
endpoint config with a non-working one.

58f8fab8a4 net: asix: add write_hwaddr function
All ASIX chipsets aside from AX88172 are able to set the MAC
address on the hardware level. Add a function to expose this
ability.

To differentiate between chip types we now carry flags as driver
private data. Also while touching the asix_dongles array
constify this.

5fae53d0f1 net: asix: split out basic reset function
The basic device reset ensures that the device is ready to
service commands and does not need to get redone before each
network operation.

Split out the basic reset from asix_init() and instead call it
from asix_eth_get_info(), so that it only gets called once.

f1273f1143 USB: Fix strict aliasing in ohci-hcd
commit 5f6aa03fda
    USB: Fix complaints about strict aliasing in OHCI-HCD

tried to fix this, but gcc4.4 still complains. So, this
patch basically reverts the above and does a simpler fix.

also, the above commit incorrectly changed
	/* corresponds to data_buf[4-7] */
	datab [1] = 0;
to

	/* corresponds to databuf.u8[4-7] */
	databuf.u8[1] = 0;

5cec214ecd ehci-hcd: Boost transfer speed
This patch takes advantage of the hardware EHCI qTD queuing mechanism to avoid
software and transfer splitting overhead so as to make transfers as fast as
possible.

The only drawback is a call to memalign. However, this is fast compared to the
transfer timings, and the heap size to allocate is small, e.g. 128 kiB in the
worst case for a transfer length of 65535 packets of 512 bytes.

Tested on i.MX25, i.MX35 and i.MX51. In my test conditions, the speed gain was
very significant (several times faster), which is really appreciable when
accessing large files.

189a6956eb ehci-hcd: fix external buffer cache handling
Buffer coming from upper layers should be cacheline aligned/padded
to perform safe cache operations. For now we don't do bounce
buffering so getting unaligned buffer is an upper layer error.
We can't check if the buffer is properly padded with current
interface so just assume it is (consider changing with in the
future). The following changes are done:

1. Remove useless length alignment check. We get actual transfer
length not the size of the underlying buffer so it's perfectly
valid for it to be unaligned.
2. Move flush_dcache_range() out of while loop or it will
flush too much.
3. Don't try to fix buffer address before calling invalidate:
if it's unaligned it's an error anyway so let cache subsystem
cry about that.
4. Fix end buffer address to be cacheline aligned assuming upper
layer reserved enough space. This is potentially dangerous
operation so upper layers should be careful about that.

However on some platforms we have a larger minimum requirement for cache

minimum.  We add a cpp check to <usb.h> to define USB_DMA_MINALIGN and
make use of it in ehci-hcd.c and musb_core.h.  We cannot use MAX() here

b8adb12095 USB: Drop cache flush bloat in EHCI-HCD
Discard the creepy cache flushing mechanisms in ehci-hcd.c and replace them with
more straightforward flushing. In the new approach, the flushing takes place
directly in ehci_submit_async() call instead of going through the QH list and
flushing all members and buffers. This discards a lot of weird bit operations
on the members of QH and qTD structures.

NOTE: Certainly, this flushes even qTDs which are possibly unused in some
transactions, though the overhead of the previous code was much higher than is
the overhead of flushing two more cache lines (which most probably aren't even
cached).

90579fdd41 ehci-omap: fix for enabling the correct usb port
This is just a patch for the problem reported here:
http://lists.denx.de/pipermail/u-boot/2012-February/117580.html originally reported by Igor.

"Looks like this is copy paste error from my side,(for port2/3 it should have been bypass
 for port2/3 rather its port1 set in bypass mode)"

I only submit the patch since it is missing in 2012.04-rc3 while the twister board
depends on it. Maybe it is already somewhere in the reposistory, but I cannot find it.

note: the twister boards still needs an additional `usb reset`, don't know why.

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)"

In 9792987721 Stefan describes a usecase
where the previous behavior of leaving wMaxPacketSize be unaligned
caused fatal problems.  The initial fix for this problem was incomplete
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.

5f4b4f2fed ehci: speed up initialization
According to EHCI specification v1.0, the controller should stabilize
the power on a port at most 20 ms after the port power bit transition.
So, we put this setting in the virtual descriptor corresponding field,
(bPwrOn2PwrGood = 10 => 10 x 2ms = 20ms), this saves about 500ms at each
controller initialization/enumeration.

For files like the drivers/serial/serial.c, it must include the
platform file, as the CONFIG_SYS_NS16550_COM1 must reference to the

Include the platform definition file in the config file, so that it

3ecfa9525c ehci-hcd: Allow cleanups to happen gracefully on a timeout.
With this, the EHCI seems to "recover" from a timeout. This is particularly
observable if you were to ping the wrong IP Address and then ping the correct
one or if there was a temporary failure during tftp sessions.

All it takes is one timeout to disable it. If you have a noisy network (lot
of traffic), even if the traffic is not for the board, the timeouts don't occur.

69716c1900 USB: Remove __attribute__ ((packed)) for struct ehci_hccr and ehci_hcor
Remove __attribute__ ((packed)) to prevent byte access to soc
registers in some gcc versions.

Having patches to enable ehci for the BeagleBoard lying around for
several months, this one was the show-stopper.

Switched to align(4), rather than remove the attribute, per suggestion
from Alexander.

Credits have to go to Laine Walker-Avina <lwalkera@ieee.org> for
finding the problem.

6d8962e814 Switch from archive libraries to partial linking
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.

09c83a45b7 ehci-hcd.c: fix hanging under higher load
This patch solves a problem with USB hanging under higher load on a
i.MX31 board.  It falls into class of typical USB problems and fixes:
if you don't understand the real cause, add a delay somewhere.

The problem appeared after introduction of ELF relocation, which
results in smaller code, which appears to run faster (probably because
it fits better in the cache); turning off the instruction cache,
adding debug printf()s and increasing the delay have all been found to
make the problem go away.

Moving the original "udelay(1)" up in the code to it's new place made
the problem appear much less frequently. Increasing the delay to 2
microseconds then made the code run reliably in all (hour-long) tests.
To be on the safe side, we set it to 5 microseconds here.

98fae9707f USB-CDC: Prevent rx_req being enqueued twice
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:

 |   ether.c:usb_eth_init

in the loop. The driver interrupt routine is called

d5292c1647 USB-CDC: ethernet error path potential oops fix
Fix potential oops on rare error path.
The patch is based on commit e7b13ec9235b9fded90f826ceeb8c34548631351
(done by David Brownell <david-b@pacbell.net>) from linux-2.6.git.

Description of the issue taken from linux kernel bugzilla:
(https://bugzilla.kernel.org/show_bug.cgi?id=9594)

The potential error can be tracked down as follows:

(1) line 807: let the second conjunct on the "if" statment be false
    meaning "dev->status_ep" is null. This means the "if" evaluates
    to false.

follow thru the code until...

(2) line 808: usb_ep_disable(dev->status_ep) passes in a null argument,
    however "usb_ep_disable" cannot handle that:

(from include/linux/usb/gadget.h)
191 static inline int
192 usb_ep_disable (struct usb_ep *ep)
193 {
194         return ep->ops->disable (ep);
195 }

9fb3b50857 EHCI: zero out QH transfer overlay in ehci_submit_async()
ehci_submit_async() doesn't really zero out the QH transfer overlay (as the EHCI
specification suggests) which leads to the controller seeing the "token" field
as the previous call has left it, i.e.:
- if a timeout occured on the previous call (Active bit left as 1), controller
  incorrectly tries to complete a previous transaction on a newly programmed
  endpoint;
- if a halt occured on the previous call (Halted bit set to 1), controller just
  ignores the newly programmed TD(s) and the function then keeps returning error
  ad infinitum.

This turned out to be caused by the wrong orger of the arguments to the memset()
call in ehci_alloc(), so the allocated TDs weren't cleared either.

While at it, stop needlessly initializing the alternate next TD pointer in the
QH transfer overlay...

8f8bd565f3 USB Consolidate descriptor definitions
The header files usb.h and usbdescriptors.h have the same nameed
structure definitions for

usb_config_descriptor
usb_interface_descriptor
usb_endpoint_descriptor
usb_device_descriptor
usb_string_descriptor

These are out right duplicates in usb.h

usb_device_descriptor
usb_string_descriptor

This one has extra unused elements

usb_endpoint_descriptor

	unsigned char	bRefresh
	unsigned char	bSynchAddress;

These in usb.h have extra elements at the end of the usb 2.0
specified descriptor and are used.

usb_config_descriptor
usb_interface_descriptor

The change is to consolidate the definition of the descriptors
to usbdescriptors.h.  The dublicates in usb.h are removed.
The extra element structure will have their name shorted by
removing the '_descriptor' suffix.

So

usb_config_descriptor -> usb_config
usb_interface_descriptor -> usb_interface

For these, the common descriptor elements are accessed now
by an element 'desc'.

As an example

-	if (iface->bInterfaceClass != USB_CLASS_HUB)
+	if (iface->desc.bInterfaceClass != USB_CLASS_HUB)

This has been compile tested on MAKEALL arm, ppc and mips.

52cb4d4fb3 stdio/device: rework function naming convention
So far the console API uses the following naming convention:

	======Extract======
	typedef struct device_t;

	int	device_register (device_t * dev);
	int	devices_init (void);
	int	device_deregister(char *devname);
	struct list_head* device_get_list(void);
	device_t* device_get_by_name(char* name);
	device_t* device_clone(device_t *dev);
	=======

which is too generic and confusing.

Instead of using device_XX and device_t we change this
into stdio_XX and stdio_dev

This will also allow to add later a generic device mechanism in order
to have support for multiple devices and driver instances.

To prepare for the 85xx USB support, which requires interface enablement
only once in (specified) order, no different than instructions for
enabling the interface under 83xx.  It is unknown why the original author
enabled the interface twice (checked for references in errata, etc).

faa14babd7 at91: fix a USB problem for AT91SAM9261
This patch corrects the missing PLLB initialization in usb_cpu_init()
for AT91SAM9261.
Because of the missing PLLB initialization, the USB support for all
AT91SAM9261 based boards will work only if the PLLB is configured by a
precedent bootloader.
