Julius Werner baa3e70084 arm64: Align cache maintenance code with libpayload and ARM32
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).

Julius Werner d67c6876b5 Turn CBMEM console into a ring buffer that can persist across reboots
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).

BUG=chromium:651966
TEST=Rebooted and confirmed output repeatedly on a Kevin and a Falco.
Also confirmed correct behavior across suspend/resume for the latter.

Julius Werner 7b58319e9c libpayload: cbgfx: Show square images on portrait displays
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.

Julius Werner 5fae829410 libpayload: usbhub: Force enumeration of all connected ports on init
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.

Don't assume anything about the register state when the called function

still the same as before the call.

Julius Werner 58caa8ba8c libpayload: Reintroduce CONFIG_LP_CHROMEOS to set suitable defaults
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).

BUG=None

Julius Werner 4fda9bd0ec libpayload: Replace majority of timer drivers with a generic one
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.

Julius Werner f975e55dcd cbfs: Add "struct" file type and associated helpers
This patch adds functionality to compile a C data structure into a raw
binary file, add it to CBFS and allow coreboot to load it at runtime.
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.

Julius Werner 1143d08f7e libpayload: head.S: Avoid clearing BSS (and heap) again
3 out of 4 architectures currently zero out the payload BSS in early
assembly code, which is pointless since the code loading the payload has
already done that (with a more efficient memset). ARM64 has never had
any code like this and can run just fine without it. This also defeats
the new optimization of moving the heap out of the BSS, since all three
implementations assume that everything between _edata and _end is BSS.
We should just take this out.

Julius Werner e25d3ff9bd libpayload: lzma: Allocate scratchpad on the heap
Allocating a 15980-byte scratchpad on the stack when your default stack
size is set to 16KB is really not a great idea. We're regularly
overflowing into the end of our heap when using LZMA in libpayload, and
just happen not to notice it because the heap rarely gets filled up all
the way. Of course, since we always *have* a heap in libpayload, the
much saner solution is to just use it directly to allocate the
scratchpad rather than accidentally grow backwards into it anyway.

the overlap with ranges in that list is checked with

cbgfx currently makes a separate function call (recomputing some values)
for every single pixel it draws. While we mostly don't care that much
about display speed, this can become an issue if you're trying to paint
the whole screen white on a lowly-clocked Cortex-A53. As a simple
solution for these extreme cases, we can build a fast path into
clear_screen() that just memset()s the whole framebuffer if the color
and pixel format allow it.
