Jimmy Zhang f4ef77e844 tegra: i2c: re-init i2c controller after reset
This serves as supplemental patch to CL:197732. After clearing bus, we
should also redo controller init (because controller has been reset
before bus clear). On the upper layer, upon receiving error return status,
it should just retry instead of simply call cpu_reset().

The EC can export ALS information if the sensor is attached
to it directly rather than to the host.  This adds a basic
ACPI ALS device and implements the required information.

The kernel does not use the _ALR tuple set but it is required
by the ACPI spec so this just adds the sample two point
response curve defined in ACPI 5.0 section 9.2.5.

The EC does not currently send events for lux value changes so
a polling interval of 1 second is defined.

Julius Werner dbadb1dd63 libpayload: Reorder default memcpy, speed up memset and memcmp
The current default memcpy first copies single bytes to align the
amount, then copies the rest as full words. In practice, the start of a
buffer is much more likely to be word-aligned then the end, and aligned
word access are usually more efficient. This patch reorders those
accesses to first copy as many full words as possible and then finish
the rest with byte accesses to optimize this common case.

This fixes a data abort when using USB on ARM without CONFIG_GPL. Due to
some limitations of how DMA memory is set up in coreboot on ARM, it
currently does not support unaligned accesses. (This could be fixed with
a more complicated patch, but it's usually not an issue... unless, of
course, your memcpy happens to be braindead).

Also add word-aligned accesses to memset and memcmp while I'm at it, and
make memcmp's return value standard's compliant.

Julius Werner 50a81748fd libpayload: Add remote GDB support
This patch adds the ability to attach a GDB host through the UART to a
running payload. Libpayload implements a small stub that can parse and
respond to the GDB remote protocol and provide the required primitives
(reading/writing registers/memory, etc.) to allow GDB to control
execution.

The goal of this implementation is to be as small and uninvasive as
possible. It implements only the minimum amount of primitives required,
and relies on GDB's impressive workaround capabilities (such as
emulating breakpoints by temporarily replacing instructions) for the
more complicated features. This way, a relatively tiny amount of code on
the firmware side opens a vast range of capabilities to the user, not
just in debugging but also in remote-controlling the firmware to change
its behavior (e.g. through GDBs ability to modify variables and call
functions).

By default, a system with the REMOTEGDB Kconfig will only trap into GDB
when executing halt() (including the calls from die_if(), assert(), and
exception handlers). In addition, payloads can manually call gdb_enter()
if desired. It will print a final "Ready for GDB connection." on the
serial, detach the normal serial output driver and wait for the commands
that GDB starts sending on attach.

Based on original implementation by Gabe Black <gabeblack@chromium.org>.

(You can also SIGSTOP your terminal's parent shell and the terminal
itself, and SIGCONT them in reverse order after GDB exits. More
convenient wrapper tools to do all this automatically coming soon.)

Julius Werner 22adcd67a2 libpayload: Introduce new Kconfig to explicitly allow GPL code
There have been leaks of GPL code into libpayload for a while now, for
new features or improvements that require third party code with no
adequate alternative among BSD-licensed software. It seems silly and
counter-productive to keep holding back features and performance
improvements from libpayload for a use-case (proprietary payloads) that
doesn't even seem to be implemented anywhere to date. Open-source
payloads should not need to suffer to appease commercial ones.

Instead, this patch introduces a new Kconfig option to explicitly allow
inclusion of GPL code. It will use Kconfig dependencies and/or Makefile
rules to ensure that no GPL code can end up in the final payload if that
option is unset, allowing proprietary payloads to keep working with the
existing BSD-licensed feature set. New features and patches (that are
sufficiently separate and self-contained to allow guarding through this
config option) can choose whether to import GPL code, and need to depend
on this option if they do.

Also clean up all (known) existing uses of GPL code to depend on the new
option, add some recent third-party imports to the LICENSES file, and
relicense the selfboot.c files to BSD with permission of the author.

Julius Werner 092cac58de libpayload: Rework exception hook interface
This patch makes some slight changes to the exception hook interface.
The old code provides a different handler hook for every exception
type... however, in practice all those hook functions often need to look
very similar, so this creates more boilerplate than it removes. The new
interface just allows for a single hook with the exception type passed
as an argument, and the consumer can signal whether the exception was
handled through the return value. (Right now this still only supports
one consumer, but it could easily be extended to walk through a list of
hooks if the need arises.)

Also move the excepton state from an argument to a global. This avoids a
lot of boilerplate since some consumers need to change the state from
many places, so they would have to pass the same pointer around many
times. It also removes the false suggestion that the exception state was
not global and you could have multiple copies of it (which the exception
core doesn't support for any architecture).

On the ARM side, the exception state is separated from the exception
stack for easier access. (This requires some assembly changes, and I
threw in a few comments and corrected the immediate sigils from '$' to
the official '#' while I'm there.) Since the exception state is now both
stored and loaded through an indirection pointer, this allows for some
very limited reentrance (you could point it to a different struct while
handling an exception, and while you still won't be able to return to
the outer-level exception from there, you could at least swap out the
pointer and return back to System Mode in one go).

BUG=chrome-os-partner:18390
TEST=Made sure normal exceptions still get dumped correctly on both
archs.

libpayload: align arm64 with new exception handling model

The exception handling was previously updated, however the
arm64 changes raced with hat one. Make the arm64 align with
the new model. Without these changes compilation will fail.

Julius Werner 43e10301c0 libpayload: Add ability to unregister output driver
This patch adds a console_kill_output_driver() function, which can
remove a previously registered output driver. This is mostly useful when
you overlay some output channel over another, such as when the GDB stub
takes direct control of the UART (and thus has to get rid of the
existing serial output driver).

Stefan Reinauer d6865222c8 misc: Drop print_ implementation from non-romcc boards
Because we had no stack on romcc boards, we had a separate, not as
powerful clone of printk: print_*.

Back in the day, like more than half a decade ago, we migrated a lot
of boards to printk, but we never cleaned up the existing code to be
consistent. Instead, we worked around the problem with a very messy
console.h (nowadays the mess is hidden in romstage_console.c and
early_print.h)

This patch cleans up the generic code pieces to use printk() on all
non-ROMCC boards.

Our two remaining ROMCC boards are fixed up in this commit:
bifferos/bifferboard and dmp/vortex86ex.

Martin Roth d7689e4ad5 Doxygen: add a "simple" output config and make target
This is a doxygen target I'm using for cleaning up the coreboot doxygen
output.  It runs in about a minute instead of....  a lot longer, and
only generates documentation for the coreboot/src directory, excluding
vendorcode.

It was requested that the comments be stripped to make it easier to
read.  This was done through the following command (split for gerrit):

head -n 1 Doxyfile.coreboot_simple > Doxyfile.tmp ;
cat Doxyfile.coreboot_simple | sed 's|^\s*#.*$||' | sed '/^$/d' | sed 's|[[:space:]]\+$||' >> Doxyfile.tmp ;
mv Doxyfile.tmp Doxyfile.coreboot_simple

I'm including the command here because any time the file is updated
with the doxygen wizard, it will need to be run again.  It might be
desirable to turn this into a script in the documentation directory.

Stefan Reinauer d548e5c6d9 broadwell: Use correct include file for console functions
console_tx_byte() is defined in stream.h, not console.h. This will cause
problems later, when untangling more ROMCC and console code. Hence, fix
the issue beforehand.

Vadim Bendebury 897123ab2f libpayload: ipq808x: introduce uart driver
This adds a UART driver for the ipq8064 controller. It still does not
quite work in the receive direction - the receive FIFO returns read
data in 32 bit chunks, which means that 4 keys need to be pressed
before a character pops out of the driver (and it reports it as a
single character).

This issue is being addressed separately, the driver is being checked
in to facilitate concurrent development.

BUG=chrome-os-partner:27784, chrome-os-partner:29313

TEST=with deptcharge modifications in place, the AP148 board comes up
     to the depthcharge prompt:

Starting depthcharge on storm...

Vadim Bendebury bc8b4fad1e libpayload: Introduce bit manipulation macros
Some drivers being ported to depthcharge use io bit manipulation
macros. The libpayload include file seems the most appropriate place
to keep these macros in. There is no common io.h file across
architectures, the x86 version could be added later if required.

BUG=chrome-os-partner:27784
TEST=observed ipq806x SPI driver deptcharge port (WIP) compile properly.

Vadim Bendebury b7f82e9559 libpayload: arm: add code to clear bss
This adds some assembly code to clear .bss segment. It might have been
already cleared by the loader, but it is not guaranteed. This also
helps when the program is loaded by the debugger.

BUG=none
TEST=observed that .bss is now initialized when the program is
     restarted. Verified correct boundaries of the segment.
