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>.

BUG=chrome-os-partner:18390
TEST=Boot a GDB enabled image in recovery mode (or get it to hit a
halt()), close your terminal, execute '<toolchain>-gdb --symbols
/build/<board>/firmware/depthcharge_gdb/depthcharge.elf --directory
~/trunk/src/third_party/coreboot/payloads/libpayload --directory
~/trunk/src/platform/depthcharge --directory
~/trunk/src/platform/vboot_reference --ex "target remote
<cpu_uart_pty>"' and behold the magic.
(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.

BUG=chrome-os-partner:24957
TEST=Compiled Falco and Nyan_Big both with and without the new option,
disassembled output binaries to ensure that memcpy() looks as expected.

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.

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 069f4766a0 mainboard: 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 mainboard code to use printk() on all non-ROMCC
boards.

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.

The hp/abm board is used in network/server applications.

Notes:
- The hp/abm board is headless and therefore does not define
  CONFIG_GFXUMA, and does not require a video bios.
- The micro USB connector on the board edge is connected to COM4
  (i.e. I/O=2E8h). Coreboot needs to be configured to use Index=3.
- If you are using SeaBIOS it would also need to be configured to
  use the UART at I/O=2E8h.
- This board has been tested with headless installed versions of
  Ubuntu 12.10 and Fedora 19.
