Julius Werner 69cc557cfb commonlib/bsd: Remove cb_err_t
cb_err_t was meant to be used in place of `enum cb_err` in all
situations, but the choice to use a typedef here seems to be
controversial. We should not be arbitrarily using two different
identifiers for the same thing across the codebase, so since there are
no use cases for serializing enum cb_err at the moment (which would be
the primary reason to typedef a fixed-width integer instead), remove
cb_err_t again for now.

Julius Werner db29b3765b libpayload: Fix legacy CBFS code after recent refactoring
The goal when adding the new CBFS API in CB:59497 was that the old CBFS
code would be left completely untouched and just moved to the side a
bit, so that it could continue to work for the payloads that use it
until they all have time to transition to the new CBFS API.
Unfortunately, between the different iterations of the patch something
went wrong with that and the final committed version of cbfs_legacy.c
does differ in some parts from the original code, including a changed
macro definition that breaks decompression support. This patch restores
all the legacy CBFS files to exactly what they used to be (other than
the necessary changes in cbfs_core.h to avoid double definition
clashes).

Jakub Czapiga 3d91b47b42 libpayload: Add mock architecture
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
in arch/* directories.

Furquan Shaikh bda86bd497 nvs: Add Chrome OS NVS (CNVS) information to coreboot tables
CB:51638 separated Chrome OS NVS from global NVS by allocating it
separately in CBMEM. CNVS is used in depthcharge to fill firmware
information at boot time. Thus, location of CNVS needs to be shared in
coreboot tables for depthcharge to use.

This change adds a new coreboot table tag
`CB_TAG_ACPI_CNVS`/`CB_TAG_ACPI_CNVS`(0x41) which provides the
location of CNVS in CBMEM to payload (depthcharge).

Additionally, CB:51639 refactored device nvs(DNVS) and moved it to the
end of GNVS instead of the fixed offset 0x1000. DNVS is used on older
Intel platforms like baytrail, braswell and broadwell and depthcharge
fills this at boot time as well. Since DNVS is no longer used on any
new platforms, this information is not passed in coreboot
tables. Instead depthcharge is being updated to use statically defined
offsets for DNVS.

BUG=b:191324611, b:191324611
TEST=Verified that `crossystem fwid` which reads fwid information from
CNVS is reported correctly on brya.

Furquan Shaikh 493937e1d6 coreboot tables: Add SPI flash memory map windows to coreboot tables
This change adds details about the memory map windows to translate
addresses between SPI flash space and host address space to coreboot
tables. This is useful for payloads to setup the translation using the
decode windows already known to coreboot. Until now, there was a
single decode window at the top of 4G used by all x86
platforms. However, going forward, platforms might support more decode
windows and hence in order to avoid duplication in payloads this
information is filled in coreboot tables.

`lb_spi_flash()` is updated to fill in the details about these windows
by making a call to `spi_flash_get_mmap_windows()` which is
implemented by the driver providing the boot media mapping device.

However, these header files do not include the compiler.h macro that
defines what __packed is, so they are actually defining a variable named

same variable multiple times, which was caught by GCC 10. Add compiler.h
to the compiler parameters so it is included in all files automatically.

Tim Wawrzynczak e1a7a26f5e lib/libpayload: Replace strapping_ids with new board configuration entry
There are currently 3 different strapping ID entries in the coreboot
table, which adds overhead. The new fw_config field is also desired in
the coreboot table, which is another kind of strapping id. Therefore,
this patch deprecates the 3 current strapping ID entries (board ID, RAM
code, and SKU ID), and adds a new entry ("board_config") which provides
board ID, RAM code, SKU ID, as well as FW_CONFIG together.

Use `bool` whenever `0` was used to indicate an error. The mixing of
different types for return values was mildly confusing and potentially
dangerous with the i8042 API close by that uses `0` for success.

Patrick Rudolph bc744f5893 drivers/smmstore: Implement SMMSTORE version 2
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.

An example EDK2 implementation can be found here:

Hung-Te Lin d04b388381 libpayload: cbgfx: Support buffered I/O
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.

Nico Huber 5e0db58533 libpayload: Cache copy of `cb_framebuffer` struct
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().
