The arm32 GDB architecture code contains a little hack that allows it to
(sort of) correctly deal with a reentrant exception triggered from
within the GDB stub. The main logic for this isn't really arm32 specific
and could be useful for other architectures as well, so factor it out
into a separate function.

This patch reworks the arm64 exception handling to be more similar to
how it works on arm32. This includes a bunch of features like actually
saving and restoring more exception state in the exception_state
structure and supporting the same sort of partial reentrancy that is
useful for GDB. Since there's no instruction to directly load into or
store out of SP on arm64, we can't do quite the same thing where we use
that to read an exception_state_ptr variable right after exception entry
when no other register is available. But we can do something very
similar by (ab-)using the "high" stack pointer (SP_EL2) as a pointer to
the exception_state struct and providing a function to change it.

This patch adds the new, faster architectural register accessors to
libpayload that were already added to coreboot in CB:27881. It also
hardcodes the assumption that coreboot payloads run at EL2, which has
already been hardcoded in coreboot with CB:27880 (see rationale there).
This means we can drop all the read_current/write_current stuff which
added a lot of unnecessary helpers to check the current exception level.
This patch breaks payloads that used read_current/write_current
accessors, but it seems unlikely that many payloads deal with this stuff
anyway, and it should be a trivial fix (just replace them with the
respective _el2 versions).
Also add accessors for a couple of more registers that are required to
enable debug mode while I'm here.

I need to setup the APIC timer to fire interrupts. I would like to reuse
the existing interrupt table. So I extended it to support user defined
interrupts. I just added all 255 vectors so there wouldn't need to be
any additional build time configuration.
I'm going to deprecate exception_install_hook and remove it in a follow
up. It will be replaced with set_interrupt_handler. This way the
exception lookup does not have to manage a list of callbacks, or have to
worry about the order they are processed.

In order to support booting a GNU/Linux payload on non x86, the FIT format
should be used, as it is the defacto standard on ARM.
Due to greater complexity of FIT it is not converted to simple ELF format.
Add support for autodecting FIT payloads and add them as new CBFS_TYPE 'fit'.
The payload is included as is, with no special header.
The code can determine the type at runtime using the CBFS_TYPE field.
Support for parsing FIT payloads in coreboot is added in a follow on
commit.
Compression of FIT payloads is not supported, as the FIT sections might be
compressed itself.
Starting at this point a CBFS payload/ can be either of type FIT or SELF.
Tested on Cavium SoC.

When GDB support is compiled in, halt() in libpayload will call
gdb_enter(). halt() is defined in <stdlib.h> and gdb_enter() in
<libpayload.h>. Usually files just include <libpayload.h> so this is not
a problem, but in some situatons a payload may just include <stdlib.h>
(or a file including it like <assert.h>), leading to an undeclared
identifier here. Move the GDB functions to <stdlib.h> to solve this.

The USBHID driver zero-initializes some but not all of the fields in its
usbhid_inst_t structure. This is a problem because under some
circumstances, some of the uninitialized fields may be read and lead to
incorrect behavior. Some (broken) USB keyboards keep sending reports
that contain all zeroes even when they have no new keys... these usually
get silently ignored, but if the usbhid_inst_t structure is in an
inconsistent state where 'previous' is zeroed out but 'lastkeypress'
is non-zero because it wasn't properly initialized, these reports will
be interpreted as keyrepeats of the bogus 'lastkeypress'. This patch
changes the code to just xzalloc() the whole structure so we won't have
to worry about initialization issues anymore.

bebitenc() just runs a downward loop over the same body as lebitenc().
That doesn't give you a byte-swapped result, it gives you the same final
value, just starting from the other side to fill it in. (Also, it
confused i++ and i--, so it really gives you a compiler error.)
The correct code needs to have the array index inverted relative to the
bit shift index to produce a big endian result.

If the framebuffer address is zero the corebootfb_init() function
should abort and not attempt to use it for video, otherwise it
will likely hang.
This was tested by booting on a board that does not have a display
attached and includes the previous patch to zero the framebuffer
structure in the coreboot tables.

Add a Kconfig value to enable building libpayload with the 586 compiler.
Update the cross compiler script to add the Kconfig value name that is
used when libpayload builds.
The Quark SOC does not support some of the instructions generated with
the 686 compiler (e.g. CMOV). Success occurs when
payloads/libpayload/build/config.h indicates that
CONFIG_LP_USE_MARCH_586=1.
TEST=Build and run on Galileo Gen2.

coreboot and libpayload currently use completely different code to
perform a full cache flush on ARM64, with even different function names.
The libpayload code is closely inspired by the ARM32 version, so for the
sake of overall consistency let's sync coreboot to that. Also align a
few other cache management details to work the same way as the
corresponding ARM32 parts (such as only flushing but not invalidating
the data cache after loading a new stage, which may have a small
performance benefit).

This patch allows the CBMEM console to persist across reboots, which
should greatly help post factum debugging of issues involving multiple
reboots. In order to prevent the console from filling up, it will
instead operate as a ring buffer that continues to evict the oldest
lines once full. (This means that if even a single boot doesn't fit into
the buffer, we will now drop the oldest lines whereas previous code
would've dropped the newest lines instead.)
The console control structure is modified in a sorta
backwards-compatible way, so that new readers can continue to work with
old console buffers and vice versa. When an old reader reads a new
buffer that has already once overflowed (i.e. is operating in true ring
buffer mode) it will print lines out of order, but it will at least
still print out the whole console content and not do any illegal memory
accesses (assuming it correctly implemented cursor overflow as it was
already possible before this patch).

CBGFX currently doesn't support portrait screens at all. This will have
to be fixed eventually but might take a bit of effort. As a first step
to make devices with a portrait panel somewhat usable, this patch will
just force a square canvas on these panels and keep the bottom part of
the screen black.
Also switch set_pixel to calculate framebuffer position via
bytes_per_line instead of x_resolution. This is supposed to be the
canonical way to do that and may differ in cases where the display
controller requires a certain alignment from framebuffer lines.
