A new ChromeOS automated test will be introduced to check the cbmem log
of diagnostic boot mode. Because the diagnostic boot does not allow
booting into kernel, the test must perform AP reset and then check the
cbmem log afterwards. However, the memory content might not be written
back to memory (from CPU cache) during AP reset because of the cache
snooping mechanism on x86. Hence, some API to flush cache is needed.
Implement dcache_* to allow flushing cache proactively in x86. To avoid
unnecessary flush, check dma_coherent before calling dcache_* functions,
which will be always true in x86. Therefore, this change won't affect
the original functionality.

When removing SD card from USB card reader, the USB MSC stack does
not detach the device immediately. Instead, the USB MSC stack calls
usbdisk_remove() and calls usb_msc_destroy() after several pollings.
It results in usbdisk_remove() being called twice.
Since the usbmsc_inst_t instance is freed after first usbdisk_remove()
call, the second call invokes an invalid usbmsc_inst_t instance and
causes exception in CPU.
This patch prevents usbdisk_remove() from being called twice by setting
usbdisk_created to zero.

the actual order of pixels being set depends on the framebuffer
orientation. With NORMAL orientation, the framebuffer is accessed
sequentially; with LEFT_UP/RIGHT_UP orientation, it is accessed back and

Therefore, ensure sequential access to the framebuffer, regardless of

Even if we are careful, it's still possible that we read spurious
data from the keyboard, e.g. keystrokes. Namely, when we send the
reset/disable command, there is a race before the command is pro-
cessed.
So we should always process data from the keyboard in a loop. We
break it, when an ACK (0xfa) or a NAK (0xfe) is received, and warn
on unexpected data unless it might be due to the mentioned race.
This also gives us the opportunity to use command-specific timeouts
which we take from Linux: 1s for the keyboard self-test (as there
are keyboards that perform the test before acking the command) and
200ms for all other commands.

Some background first: The original XT keyboards used what we call
scancode set #1 today. The PC/AT keyboards introduced scancode set #2,
but for compatibility, its controller translated scancodes back to
set #1 by default. Newer keyboards (maybe all we have to deal with)
also support switching the scancode set.
This means the translation option in the controller and the scancode
set selection in the keyboard have to match. In libpayload, we only
support set #1 scancodes. So we either need the controller's trans-
lation on and set #2 selected in the keyboard, or the controller's
translation off and set #1 selected in the keyboard.
Valid configurations:
* SET #1 + XLATE off
* SET #2 + XLATE on
Both with and without the PC_KEYBOARD_AT_TRANSLATED option, we were
only configuring one of the two settings, leaving room for invalid
configurations. With this change, we try to select scancode set #2
first, which seems to be the most supported one, and configure the
controller's translation accordingly. We try to fall back to set #1
on failure.
We also keep translation disabled during configuration steps to
ensure that the controller doesn't accidentally translate confi-
guration data.
On the coreboot side, we leave the controller's translation at its
default setting, unless DRIVERS_PS2_KEYBOARD is enabled. The latter
enables the translation unconditionally. For QEMU this means that
the option effectively toggles the translation, as QEMU's controller
has it disabled by default. This probably made a lot of earlier
testing inconsistent.
Fixes: commit a95a6bf646 (libpayload/drivers/i8402/kbd: Fix qemu)
The reset introduced there effectively reverted the scancode
selection made before (because 2 is the default). It's unclear
if later changes to the code were only necessary to work
around it.

The current initialization of the 'equals' counter is incorrect, so that
when 'equals >= SSZ * SSZ', the pixels in the sample array might not be
all the same, leading to a wrong pixel value being set in the
framebuffer.
The 'equals' counter stores the number of latest pixels that were
exactly equal. Within the for loop of 'ox', the sample array is updated
in a column-based order, and the 'equals' counter is updated
accordingly. However, the 'equals' counter is initialized in a row-based
order, which causes it to be set too large than it should be. Consider
the example where sample[sx][sy] are initially:
[X X X A A A] // sy = 0
[X X X B B B]
[X X X B B B]
[X X X B B B]
[X X X B B B]
[X X X B B B] // sy = SSZ
Then, the correct implementation will initialize 'equals' to be 15, with
last_equal being B. Suppose all of the remaining pixels are B. Then, at
the end of the 'while (fpfloor(ixfp) > ix)' loop when ix = 4, or
equivalently after 4 more columns of sample are updated, 'equals' will
be 15 + 6 * 4 = 39, which is greater than SSZ * SSZ = 36, but we can see
there are still 2 A's in the sample:
[B B B B A A]
[B B B B B B]
[B B B B B B]
[B B B B B B]
[B B B B B B]
[B B B B B B]
Therefore, we must also initialize the 'equals' counter in a
column-based order.

We do not need to set the CS (Command Stop) bit in the Command Ring
Control Register. CS is implied by CA (Command Abort). I'm not sure if
there is a defined execution order for these command bits, so it's
safer to only use the CA bit as it includes the CS function.

This fixes issues with how we handle events generated by the xHCI
"command abort" command. first, depending on the state of the xHCI
controller, the COMMAND_ABORTED may not be generated. If the
controller was between commands, only the COMMAND_RING_STOPPED event
will be generated. Second, do not adjust the command ring "cur"
pointer as that just confuses the controller.

For payloads with UI based on CBGFX, they usually start by calling
clear_canvas or clear_screen and then draw the UI elements. However,
that makes the screen flicker.
A typical solution is to identify and minimize the area to redraw.
However for payloads with complicated UI and do not care about latency,
an alternative is to enable buffered I/O.
The new enable_graphics_buffer() will redirect all graphics I/O
into an invisible working buffer. To flush (redraw) the buffer to the
real screen, call flush_graphics_buffer(). To stop buffering, call
disable_graphics_buffer().
BUG=None
TEST=Add the enable, flush and disable calls to payload 'depthcharge',
built a firmware and boots into Chrome OS recover UI. No more
flickering. The average rendering time on x86 platform is 1.2ms.

Our AArch64 code supports dynamic framebuffer allocation which
makes it necessary to change the framebuffer information during
runtime. Having a pointer inside `libsysinfo` made a mess of it
as the pointer would either refer to the original struct inside
the coreboot table or to a new struct inside payload space. The
latter would be unaffected by a relocation of the payload.
Instead of the pointer, we'll always keep a copy of the whole
struct, which can be altered on demand without affecting the
coreboot table. To align the `video/graphics` driver with the
console driver, we also replace `fbaddr` with a macro `FB` that
calls phys_to_virt().
