Jonathan Neuschäfer 062c729c9b drivers/uart: Allow the 8250IO driver only on x86
The driver relies on I/O space access functions (inb, etc.), which are
only available on x86.

Rather than explicitly disallowing it on ARM, allow it only on x86.

TEST=Configure for RISC-V, and see that "Serial port on SuperIO" is not
available in the "Generic Drivers" menu anymore.

Aaron Durbin 4b032e457f arch/x86: allow idt to be available to link in all stages
Add Kconfig IDT_IN_EVERY_STAGE to optionally specify having
the interrupt handling code available to all stages. In order
to do this the idt setup is moved to a C module. The vecX
entries are made global so that a table of references to all
the interrupt vector entry points can be used to dynamically
initialize the idt. The ramification for ramstage is that
exceptions are initialized later (lib/hardwaremain.c). Not
all stages initialize exceptions when this Kconfig variable
is selected, but bootblock for the C, stages using
assembly_entry.S, and of course ramstage do. Anything left
out just needs a call to exception_init() at the right
location.

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.

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.
