BOOTBOOT is a multi-platform, architecture agnostic boot protocol.
The protocol describes how to boot an ELF64 or PE32+ executable inside
an initial ram disk image into clean 64 bit mode. This version uses
libpayload to do that. Depending on the lib's configuration, initrd
can be in ROM as a cbfs file or a Flashmap partition; on disk a GPT
partition or a file on a FAT formatted ESP partition.

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.

The current realloc() works by freeing the origin buffer, allocating a
new one, and copying the data over. It's true that free() won't touch
the actual memory. However, the alloc() following it will potentially
modify the memory that belongs to the old buffer in order to create a
new free block (right after the newly allocated block). This causes 8
bytes (HDRSIZE) to be overwritten before being copied to the new buffer.
To fix the problem, we must create the header of the new free block
after the data is copied. In this patch, the content of alloc() is split
into two functions:
1. find_free_block(): Find a free block with large enough size, without
touching the memory
2. use_block(): Update the header of the newly allocated block, and
create the header of the new free block right after it
Then, inside realloc(), call memmove() call right after
find_free_block() while before use_block().

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().

default_memmove() calls memcpy() when (src > dst). This is safe for the
default_memcpy() implementation, but just calling memcpy() may invoke an
architecture-specific implementation. Architectures are free to
implement memcpy() however they want and may assume that buffers don't
overlap in either direction. So while this happens to work for all
current architecture implementations of memcpy(), it's safer not to rely
on that and only rely on the known implementation of default_memcpy()
for the forwards-overlapping case.

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

Add a function draw_line() to draw either a horizontal or vertical line
segment.
Theoretically a horizontal line can also be drawn by calling
draw_rounded_box() with dim_rel.x being the line length and dim_rel.y
being the line width. However, due to the truncation in integer division
when converting relative coordinates to absolute ones, this will
potentially produce inconsistent line widths, depending on the value of
pos_rel.y.
It is guaranteed that draw_line() will produce consistent line widths,
regardless of the position of the line. Also, when the thickness
argument is zero, this function is able to draw a line with 1-pixel
width, which is not achievable by draw_rounded_box().

This patch improves the image resampling (scaling) code in CBGFX to use
the Lanczos algorithm that is widely considered the "best" resampling
algorithm (e.g. also the first choice in Python's PIL library). It is of
course much more elaborate and therefore slower than bilinear
resampling, but a lot of the difference can be made up with
optimizations, and the resulting code was found to still produce
acceptable speeds for existing Chrome OS UI use cases (on an Arm
Cortex-A55 device, time to scale an image to 1101x593 went from ~88ms to
~275ms, a little over 3x slowdown). Nevertheless, if this should be too
slow for anyone there's also an option to tune it down a little, but
still much better than bilinear (same operation was ~170ms with this).

With the stub video_console_init() removed from depthcharge in
CL:2241493, depthcharge will fail to compile:
payloads/libpayload/gdb/stub.c:76: undefined reference to
`video_console_init'
Since video_console_init() is meant to be implemented in
libpayload, libpayload should be consistent with itself by not calling
this function when it's not implemented (i.e., when !LP_VIDEO_CONSOLE).
Therefore, initialize video console only if LP_VIDEO_CONSOLE is set.

This fixes a logic bug in how timeouts are reported back. In the
timeout case, the original code would return -1 instead of 0. All call
sites expect a return value of 0 as the timeout indicator.

This adds a hook so that a payload can optionally perform USB service
functions in conjunction with regular USB port status polling. In
particular, this allows depthcharge to control the state of an
external USB mux. Some SoCs like Tiger Lake have a USB mux for Type-C
ports that must be kept in sync with the state of the port as reported
by the TCPC. This can be achieved by hooking into the poll routine to
refresh the state of the USB mux.

When drawing two adjacent boxes with draw_box(), there will be a gap
between them. This is due to the truncation in integer division when
calculating the bottom right coordinate of the box.
In this patch, the relative bottom right coordinate is calculated before
transforming to an absolute one. The same issue is also fixed for
draw_rounded_box().
Also check validity of 'pos_rel' and 'dim_rel' arguments for
draw_rounded_box().
