With LinuxBoot Linux relied on the legacy method of fetching the RSDP
pointer to get ACPI. This uses a more modern approach available since
2018 on the Linux kernel, which involves filling in the zero page.
This method takes precedence over any other method of fetching the
RSDP in Linux (UEFI, Kexec, Legacy/BIOS). Some UEFI zealots are
threatening that legacy code will be removed from Linux so it's best
to already adapt to that possibility.
Tested on Qemu:
- With qemu the RSDP is always in the EBDA, so checking if Linux uses
the provided pointer is better done with a forced bad entry
- With a fake bad pointer Linux correctly does not find RDSP

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.

extract_partition() due to parted detecting that there are overlapping
partitions, and therefore failing to print the partition layout

that ROOT-A is always partition #3, and calculate the partition
start and size using the sector size.

This patch adds a new --loglevel option to the CBMEM utility which can
be used either numerically (e.g. `cbmem -1 --loglevel 6`) or by name
(e.g. `cbmem -c --loglevel INFO`) to restrict the lines that will be
printed from the CBMEM console log to a maximum loglevel. By default,
using this option means that lines without a loglevel (which usually
happens when payloads or other non-coreboot components add their own
logs to the CBMEM console) will not be printed. Prefixing a `+`
character to the option value (e.g. `--loglevel +6` or
`--loglevel +INFO`) can be used to change that behavior.

In order to provide the same loglevel prefixes and highlighting that
were recently introduced for "interactive" consoles (e.g. UART) to
"stored" consoles (e.g. CBMEM) but minimize the amont of extra storage
space wasted on this info, this patch will write a 1-byte control
character marker indicating the loglevel to the start of every line
logged in those consoles. The `cbmem` utility will then interpret those
markers and translate them back into loglevel prefixes and escape
sequences as needed.
Since coreboot and userspace log readers aren't always in sync,
occasionally an older reader may come across these markers and not know
how to interpret them... but that should usually be fine, as the range
chosen contains non-printable ASCII characters that normally have no
effect on the terminal. At worst the outdated reader would display one
garbled character at the start of every line which isn't that bad.
(Older versions of the `cbmem` utility will translate non-printable
characters into `?` question marks.)

added the word SuperIO to the checkpatch spelling list.

1) This introduced a problem because the comparison is used in different
cases in different places. The misspelled word is compared ignoring
the case, but when looking for the correct word, it looks through the
list for the misspelling in all lowercase. When it couldn't find the
word "superio" in the list, the variable came back uninitialized.
2) The spellcheck feature isn't enabled in checkpatch unless the option
--strict is enabled, so this wasn't getting reported anyway.
3) SuperIO (or superio) will match the KCONFIG options such as
CONFIG_SUPERIO_NUVOTON_NCT5104D, and suggest "Super I/O" which doesn't
make any sense.
