It’s unclear why this option was commented out. Activate the line, and
copy the CMOS layout and defaults from qemu-i440fx.
TEST=Boot 2.11.1(Debian 1:2.11+dfsg-1ubuntu7) and see that nvramcui

All ARM architecture boards are supposed to have a TTB region for their
page tables. ARM systems cannot use the data cache without enabling
paging, so it is imperative to do that as soon as possible. They will
also fault on unaligned accesses when not using the cache, which breaks
assumptions in CBFS code.
Unfortunately, we have some old boards in various stages of disrepair in
the tree that don't always follow these sorts of standard conventions.
It's not clear whether they actually boot anymore and if anyone still
has the respective hardware available to maintain them. I cannot really
fix and test them right now, but we should at least create a fake TTB
section for them so that common architecture code may make the correct
assumptions about which regions exist.

Current patch fixes problem with validation of ACPI in Linux kernel:
ACPI BIOS Error (bug): A valid RSDP was not found (20180313/tbxfroot-210)

There have been discussions about removing this since it does not seem
to be used much and only creates troubles for boards without defaults,
not to mention that it was configurable on many boards that do not
even feature uart.
It is still possible to configure the baudrate through the Kconfig

These functions will allow us to remove hardcodes,

implement the configstring correctly. Hence, for the
most part, we'll start with mainboard changes first.

which has a default value that works on all existing
systems but which can be changed
as needed for a new SOC or mainboard.

This version of coreboot successfully starts a Harvey (Plan 9) kernel as a payload,
entering main() with no supporting assembly code for startup. The Harvey port
is not complete so it just panics but ... it gets started.
We provide a standard payload function that takes a pointer argument
and makes the jump from machine to supervisor mode;
the days of kernels running in machine mode are over.
We do some small tweaks to the virtual memory code. We temporarily
disable two functions that won't work on some targets as register
numbers changed between 1.7 and 1.9. Once lowrisc catches up
we'll reenable them.
We add the PAGETABLES to the memlayout.ld and use _pagetables in the virtual
memory setup code.
We now use the _stack and _estack from memlayout so we know where things are.
As time goes on maybe we can kill all the magic numbers.

Almost all boards and chipsets within the codebase assume or
use SPI flash as the boot device. Therefore, provide an option
for the boards/chipsets which don't currently support SPI flash
as the boot device. The default is to assume SPI flash is the
boot device unless otherwise instructed. This falls in line
with the current assumptions, but it also allows one to
differentiate a platform desiring SPI flash support while it not
being the actual boot device.
One thing to note is that while google/daisy does boot with SPI
flash part no SPI API interfaces were ever implemented. Therefore,
mark that board as not having a SPI boot device.

Since commit 3bfd7cc (drivers/pc80: Rework normal / fallback selector
code) the reboot counter stored in `reboot_bits` isn't reset on a reboot
with `boot_option = 1` any more. Hence, with SKIP_MAX_REBOOT_CNT_CLEAR
enabled, later stages (e.g. payload, OS) have to clear the counter too,
when they want to switch to normal boot. So change the bits to (h)ex
instead of (r)eserved.
To clarify their meaning, rename `reboot_bits` to `reboot_counter`. Also
remove all occurences of the obsolete `last_boot` bit that have sneaked
in again since 24391321 (mainboard: Remove last_boot NVRAM option).

mb() is used in src/arch/riscv/ and src/mainboard/emulation/*-riscv/.
It is currently provided by atomic.h, but I think it fits better into
barrier.h.
The "fence" instruction represents a full memory fence, as opposed to
variants such as "fence r, rw" which represent a partial fence. An
operating system might want to use precisely the right fence, but
coreboot doesn't need this level of performance at the cost of
simplicity.
