This patch adds a new way of implementing flash access for libpayload.
Until now all reads had to be performed using cbfs_media, which is
obsolete. From now on all reads should be performed using
boot_device_read().
This patch also provides a default implementation of boot_device_read()

coreboot stores much information in the CBMEM IMD. Until now it was
ignored. This patch makes use of these coreboot tables entries.
It also removes get_cbmem_addr() function as it is no longer needed.
Moreover, the coreboot tables entry CB_TAG_MRC_CACHE does not exist
anymore, as it is not created by the code. It was replaced by
CBMEM_ID_MRCDATA entry, so MRCDATA should now be accessible through

Mock architecture can be used to build libpayload using host compiler.
It can be enabled by setting ARCH_MOCK=y in the dotconfig. It sets
LITTLE_ENDIAN=y, as most machines these days use little-endian CPUs.
Libpayload will use HOSTCC as CC, HOSTLD as LD, etc. instead of tools
provided by xcompile.
Mock architecture configuration can be used by payloads for testing
purposes. Thanks to it, tests can be architecture-independent,
and can be executed without requiring compatible Kconfig options,
e.g. ARCH_ARM64=y for ARM64 machine. However, one has to provide
implementation for most architecture-specific functions present

SMMSTORE version 2 is a complete redesign of the current driver. It is
not backwards-compatible with version 1, and only one version can be
used at a time.
Key features:
* Uses a fixed communication buffer instead of writing to arbitrary
memory addresses provided by untrusted ring0 code.
* Gives the caller full control over the used data format.
* Splits the store into smaller chunks to allow fault tolerant updates.
* Doesn't provide feedback about the actual read/written bytes, just
returns error or success in registers.
* Returns an error if the requested operation would overflow the
communication buffer.
Separate the SMMSTORE into 64 KiB blocks that can individually be
read/written/erased. To be used by payloads that implement a
FaultTolerant Variable store like TianoCore.
The implementation has been tested against EDK2 master.

latter would be unaffected by a relocation of the payload.
Instead of the pointer, we'll always keep a copy of the whole

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().
