Nico Huber 363cd1d886 libpayload/defconfig: Set default heap size to 1MiB
libpayload's drivers keep growing. With certain hardware/payload
combinations (last time witnessed with Kontron/bSL6 and FILO), the
default configuration runs out of memory.

As there is a lot enabled by default, also set a big default heap size.

Tested with FILO on QEMU/Q35.

Yu-Ping Wu 7b54c15a67 libpayload: cbgfx: Add color mapping functionality
Similar to set_blend(), add set_color_map() for mapping background and
foreground colors of a bitmap. Also add clear_color_map() for clearing
the saved color mappings.

Note that when drawing a bitmap, the color mapping will be applied
before blending.

Also remove unnecessary initialization for static variable 'blend'.

Yu-Ping Wu b086728094 libpayload: cbgfx: Add draw_line()
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().

Nico Huber 3c7888bf29 libpayload/xhci: Try harder to read 32-bit caps at once
With commit 287cf6c7d1 (lp/drivers/usb: Work around QEMU XHCI
register issue) we restructured our capability register accesses
because the compiler used the wrong access size. While we do use
only 32-bit types now, a compiler may still try to be clever and
optimize things in unexpected ways. So we add an explicit read32()
now.

For instance for the 8-bit MaxPorts field, in the most significant
bits of `capreg + 4`, our read + mask + shift

    ((cap)->hciparams1 & 0xff000000) >> 24

was turned into a single 8-bit read instruction by GCC on x86:

      31:   0f b6 52 07             movzbl 0x7(%edx),%edx

Julius Werner 7f87812c30 libpayload: cbgfx: Replace bilinear resampling with Lanczos
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).

Example images (scaled up by a factor of 7):
Old (bilinear): https://i.imgur.com/ytr2n4Z.png
New (Lanczos a=3): https://i.imgur.com/f0vKluM.png

(32-bits integral, 32-bits fractional) fixed-point math API that is
*much* faster (observed roughly 5x speed-up) when doing intensive

operations may lose a bit more precision than expected, but overall it's
still plenty of bits for most use cases.

Also includes support for basic trigonometric functions with a small
lookup table.

Julius Werner 63358eaff6 libpayload: cbgfx: Fix add_fractions() overflow reduction
log2(1) is 0 and log2(0) is -1. If we have the int64_t 0xffffffff then
log2(0xffffffff >> 31) = log2(0x1) = 0, so the current reduction code
would not shift. That's a bad idea, though, since 0xffffffff when
interpreted as an int32_t would become a negative number.

We need to always shift one more than the current code does to get a
safe reduction. This also means we can get rid of another compare/branch
since -1 is the smallest result log2() can return, so the shift can no
longer go negative now.

Duncan Laurie 7724f1142e lp/drivers/usb: Add quirk for QEMU XHCI root hub
The QEMU XHCI driver does not implement the Port Change Detect bit
in the USBSTS register.  As a result no devices are attached without
looking at each port individually.

Detect this as a quirk based on the QEMU XHCI controller PCI ID,
and apply it to the root hub quirk list so it can get used by the
generic hub driver to skip this check.

With this change an attached USB mass storage device is detected and
able to boot when supplied to qemu:

  -drive if=none,id=usbmsc,format=raw,file=/tmp/disk.img
  -device qemu-xhci,id-xhci
  -device usb-storage,bus=xhci.0,drive=usbmsc

Julius Werner 6c1a669b44 libpayload: xhci: Do not memcpy registers
memcpy() is meant to be used on normal memory and often implemented with
architecture-specific optimizations to make that as performant as
possible. MMIO registers often have special access restrictions that may
be incompatible with whatever memcpy() does. For example, on arm64 it
uses the LDP (load pair) to load 16 bytes at a time, which makes 4-byte
MMIO registers unhappy.

This patch removes the caching of the XHCI capreg registers and changes
it back to a pointer. The CAP_GET() macro is still accessing a full
(non-bitfield) uint32_t at the end so this should still generate a
4-byte access (which was the goal of the original change in CB:39838).

Nico Huber e6b0a32cb3 libpayload: Make 8250 UART driver relocation safe
`lib_sysinfo->serial` is a virtual pointer into coreboot tables.
It's not valid across relocation. Accessing the wrong value during
relocation of FILO resulted in a hang with DEBUG_SEGMENT and UART
console enabled. Work around that by caching the whole table entry
locally.

An alternative would be to revise `sysinfo`, to contain no virtual
pointers to anything outside the payload.

Julius Werner d61350c403 libpayload: malloc: Change memcpy() to memmove() in realloc
Our realloc() works (somewhat suboptimally) by free()ing the existing
allocation and then reallocating it wherever it fits. If there was free
space before the old location, this means the new allocation may be
before the old one, and if the free space block is smaller than the old
allocation it may overlap. Thus, we should be moving memmove() instead
of memcpy() to move the block over.

This is not a problem in practice since all our existing memcpy()s are
simple iterate and copy front to back implementations which are safe for
overlaps when the destination is in front of the source. but it's still
the more correct thing to do (in case we ever change our memcpy()s to do
something more advanced or whatever).

cbfs_get_handle() and cbfs_get_attr() are both looping over elements to
find a particular one. Each element header contains the element's
length, which is used to compute the next element's offset. Invalid or
corrupted CBFS files could lead to infinite loops where the offset would
remain constant across iterations, due to 0-length elements or integer
overflows in the computation of the next offset.

This patch makes both functions more robust by adding a check that
ensure offsets are strictly monotonic. Instead of infinite looping, the
functions are now printing an ERROR and returning a NULL value.

Fix an out-of-bounds read in the LZMA decoder which happens when the src
buffer is too small to contain the 13-byte LZMA header.

Nico Huber 16043d6742 libpayload/corebootfb: Fix character buffer relocation
The `chars` pointer references the heap which is part of the payload
and relocated along with it. So calling phys_to_virt() on it was
always wrong; and the virt_to_phys() at its initialization was a
no-op anyway, when the console was brought up before relocation.

While we are at it, add a null-pointer check.
