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.

In preparation of having FIT payloads, which aren't converted to simple ELF,
rename the CBFS type payload to actually show the format the payload is
encoded in.
Another type CBFS_TYPE_FIT will be added to have two different payload
formats. For now this is only a cosmetic change.

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.

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).

We have found a non-compliant USB hub (RealTek RTS 5413) that does not
set a port's Connect Status Change bit on its USB 3.0 half if the port
had already been connected while the hub was being reset. To work around
this bug, this patch adds code to initially request the status of every
port after a hub was enumerated, clear the Connect Status Change bit if
set, and then enumerate the port iff it is currently connected,
regardless of whether the change bit was set. A similar behavior can
also be found in the Linux kernel.

Chrome OS builds always have some inherent differences to "standard"
libpayload configurations: they don't want to use curses or things like
storage drivers, they always use the coreboot framebuffer and USB, etc.
This patch reintroduces CONFIG_LP_CHROMEOS as an option that only
affects Kconfig defaults. This allows Chrome OS builds to select most of
what they need in one go and reduces board-specific .config files to
only the options that are really specific to that board.
Also restricts the 8250_SERIAL_CONSOLE Kconfig to only default to yes on
x86 boards, which probably makes sense for all of libpayload (some but
far from all ARM boards use 8250-compatible UARTs, and we should
probably not default a platform option unless it's going to be correct
with very high probability).

Currently every non-x86 platform supported by libpayload needs to
provide its own timer driver. Most of the ones we have accumulated there
look almost identical: For the frequency, return a preset constant. For
the value, read a 32-bit register, possibly read another 32-bit register
and shift+OR it with the previous one, then return that.
Let's replace this with a single .c file that can easily handle all of
those cases. Menuconfig convenience can still be maintained by providing
several presets that select different defaults for the driver's
configuration options (register address(es) and frequency).
Removes an "enabled" check from Samsung MCT driver since coreboot always
unconditionally enables that timer anyway.

This patch adds functionality to compile a C data structure into a raw

This is useful in all cases where we need to be able to have several
larger data sets available in an image, but will only require a small
subset of them at boot (a classic example would be DRAM parameters) or
only require it in certain boot modes. This allows us to load less data
from flash and increase boot speed compared to solutions that compile
all data sets into a stage.
Each structure has to be defined in a separate .c file which contains no
functions and only a single global variable. The data type must be
serialization safe (composed of only fixed-width types, paying attention
to padding). It must be added to CBFS in a Makefile with the 'struct'
file processor.

just happen not to notice it because the heap rarely gets filled up all

much saner solution is to just use it directly to allocate the
scratchpad rather than accidentally grow backwards into it anyway.
