Jonathan Neuschäfer 93c9130a67 arch/riscv: Store mprv bit in size_t
CSRs are XLEN bits wide (i.e. the same width as general purpose
registers), so size_t seems a little more correct than int.

This change doesn't affect functionality because MSTATUS_MPRV already
fits in 31 bits.

Daniel Kurtz 225b03534c soc/amd/stoneyridge: Fix smi_write32 arg order in disable_all_smi_status
The argument order for smi_write32() is offset, value.  Current code had
it backwards.

So, when disable_all_smi_status() was called by sb_slp_typ_handler(),
instead of clearing pending flag SlpTypeEvent65 (0x2) in SMIx88 SmiStatus2
by writing 0x00000002 to 0xfed80288, it would instead write
0x00000088 to 0xfed80202 - clearing the lower 2 bytes of SMIx04
Event_Enable, which disabled the lower 16 GPEs from waking the system from S3.
Thus, the EC events (Keyboard / lid switch) [GPE15] and touchpad [GPE7]
did not work as wake up sources.

BUG=b:78461678
TEST=powerd_dbus_suspend, tapping any key on keyboard wakes from S3.

Aaron Durbin 696c642afa cpu/x86: add limited runtime identity page mapping
When employing PAGING_IN_CACHE_AS_RAM more areas need to be
mapped in at runtime. Therefore, paging_identity_map_addr() is
added to support adding identity mappings. Because there are a
fixed amount of pages in cache-as-ram paging only the existing
paging structures can be used. As such that's a limitation on
what regions and length one can map. Using util/x86/x86_page_tables.go
to generate page tables will always populate all the page directory
pages. Therefore, 2MiB mappings are easy to map in.

Mario Scheithauer d127be102b siemens/mc_apl1: Provide baseboard and variant concepts
Siemens will provide further boards based on Apollo Lake. These differ
only slightly. To avoid copying the complete directory of the reference
board we simply create variants that only contain the differences, like
google/reef does.

To further the ability of multiple variant boards to share code provide
a place to land the split-up changes. This patch provides the tooling
by using a new Kconfig value, VARIANT_DIR, as well as the Make plumbing.
The directory layout with a single variant mc_apl1 (which is also the
baseboard) looks like this:

variants/baseboard - code
variants/baseboard/include/baseboard - headers
variants/mc_apl1 - code
variants/mc_apl1/include/variant - headers

New boards would then be added under their board name within the
'variants' directory.

No split has been done with providing different logic yet. This is
purely an organizational change.

Julius Werner 1732dcb90c drivers/uart: Add helper function to allow bit-banging
In some cases it may be useful to be able to bitbang a UART, such as
during early bring-up when a driver for the actual controller isn't
available yet. On some platforms we may even want to use this
permanently, such as on the SDM845 where the hardware UART controller
needs to have firmware loaded and is thus unavailable for most of the
bootblock.

This patch adds some helper code that makes it easy to implement this on
a platform, you just have to pass it a function to control the Tx pin
state and it will do the rest. It relies on the mono_time API and is
thus bound to microsecond timing granularity, but that seems to be
barely good enough for 115200 baud if the bit times are calculated
carefully.

Aaron Durbin 0f35af8f42 arch/x86: add support for cache-as-ram paging
Processors, such as glk, need to have paging enabled while
in cache-as-ram mode because the front end is agressive about
fetching lines into the L1I cache. If the line is dirty and in
the L1D then it writes it back to "memory". However, in this case
there is no backing store so the cache-as-ram data that was written
back transforms to all 0xff's when read back in causing corruption.

In order to mitigate the failure add x86 architecture support for
enabling paging while in cache-as-ram mode. A Kconfig variable,
NUM_CAR_PAGE_TABLE_PAGES, determines the number of pages to carve
out for page tables within the cache-as-ram region. Additionally,
the page directory pointer table is also carved out of cache-as-ram.
Both areas are allocated from the persist-across-stages region
of cache-as-ram so all stages utilizing cache-as-ram don't corrupt
the page tables.

The two paging-related areas are loaded by calling
paging_enable_for_car() with the names of cbfs files to load the
initial paging structures from.

Aaron Durbin c546c766c0 arch/x86/postcar: add comment clarifying reason for finalize_load()
Certain platforms need to pass different stack pointer values to
postcar depending on S3 resume or not. Add comments to ease the
reader in understanding the point. If different stack values weren't
needed the program was already cached in stage cache with the correct
value.

Aaron Durbin 851dde8255 drivers/spi: reduce confusion in the API
Julius brought up confusion about the current spi api in [1]. In order
alleviate the confusion stemming from supporting x86 spi flash
controllers:

- Remove spi_xfer_two_vectors() which was fusing transactions to
  accomodate the limitations of the spi controllers themselves.
- Add spi_flash_vector_helper() for the x86 spi flash controllers to
  utilize in validating driver/controller current assumptions.
- Remove the xfer() callback in the x86 spi flash drivers which
  will trigger an error as these controllers can't support the api.
