Julius Werner 83da50173c libpayload: xhci: Use Event Data TRBs for transfer event generation
The current XHCI code only sets IOC on the last TRB of a TD, and
doesn't set ISP anywhere. On my Synopsys DesignWare3 controller, this
won't generate an event at all when we have a short transfer that is not
on the last TRB of a TD, resulting in event ring desync and everyone
having a bad time. However, just setting ISP on other TRBs doesn't
really make for a nice solution: we then need to do ugly special casing
to fish out the spurious second transfer event you get for short
packets, and we still need a way to figure out how many bytes were
transferred. Since the Short Packet transfer event only reports
untransferred bytes for the current TRB, we would have to manually walk
the rest of the unprocessed TRB chain and add up the bytes. Check out
U-Boot and the Linux kernel to see how complicated this looks in
practice.

Now what if we had a way to just tell the HC "I want an event at exactly
*this* point in the TD, I want it to have the right completion code for
the whole TD, and to contain the exact number of bytes written"? Enter
the Event Data TRB: this little gizmo really does pretty much exactly
what any sane XHCI driver would want, and I have no idea why it isn't
used more often. It solves both the short packet event generation and
counting the transferred bytes without requiring any special magic in
software.

libpayload: Make lzma truncation non-fatal.

If the size the lzma header claims it needs is bigger than the space we have,
print a message and continue rather than erroring out. Apparently the encoder
is lazy sometimes and just puts a large value there regardless of what the
actual size is.

This was the original intention for this code, but an outdated version of the
patch ended up being submitted.

Julius Werner 985ff36bee armv7: Support stack dump after exceptions
This patch enhances the armv7 exception handlers in Coreboot and
libpayload to show the correct SP and LR registers from the aborted
context, and also dump a part of the current stack. Since we cannot
access the banked registers of SVC mode from a different exception mode,
it changes Coreboot (and its payloads) to run in System mode instead. As
both modes can execute all privileged instructions, this should not have
any noticeable effect on firmware operation (please correct me if I'm
wrong!).

Gabe Black 1ee2c6dbdf libpayload: Change CONFIG_* to CONFIG_LP_* in the kconfig.
When libpayload header files are included in the payload itself, it's possible
that the payloads config settings will conflict with the ones in libpayload.
It's also possible for the libpayload config settings to conflict with the
payloads. To avoid that, the libpayload config settings have _LP_ (for
libpayload) added to them. The symbols themselves as defined in the Config.in files
are still the same, but the prefix added to them is now CONFIG_LP_ instead of just
CONFIG_.

Julius Werner 52e3f449ac libpayload: Increase USB EHCI transfer timeout
The EHCI driver defines a maximum transfer timeout of two seconds. The
comments state that during tests the maximum amount of required transfer
time was for the SCSI TEST_UNIT_READY command on certain devices. We
have now observed a USB device (Patriot Memory 13fe:3100) that can NAK
this command for slightly more than two seconds. It will also completely
fail if the timeout hits, since it gets confused by the subsequent CSW
retry/recovery mechanism and starts producing babble errors. This patch
increases the timeout to three seconds to circumvent this problem.

To test, boot a Falco from a red-black RageXT USB stick.

checks as an easy way to generate an exception for testing purposes. It was

Built and booted into depthcharge on pit with an unaligned accesses added
after the call to exception_init in the depthcharge's main. Before this
change, the access caused an exception. After this change, the access
completed successfully.

Gabe Black cfe77beea4 libpayload: Make the region to scan for the cb tables configurable.
The address range to scan for the coreboot tables varies from machine to
machine based on the range memory occupies on the SOC being booted and on the
amount of memory installed on the machine. To make libpayload work on
different ARM systems with different needs, this change makes the region to
scan configurable. In the future, we might want to come up with a more
automatic mechanism like on x86, although there's less consistency on ARM as
far as what ranges are even memory in the first place.
