Prior to commit d1c0f958d1 ("acpi: Call acpi_fill_ssdt() only for
enabled devices"), uart_inject_ssdt() was used to set the ACPI status
(_STA) for both enabled and disabled devices. The aforementioned commit
limited it to being called only on enabled devices, which left disabled
devices without any _STA method at all -- which the OS assumes means
that the device is present and enabled.
To fix this, create the _STA method in the UART asl code for each port,
and set the return value to a name variable (STAT) which defaults to
0 (not present/disabled). Then, have uart_inject_ssdt() set STAT to
present and enabled (0xF) for UARTs actually present on the board.
TEST=build/boot google/skyrim (frostflow), dump ACPI tables, and verify
that _STA returns 0xF only for UARTs enabled in devicetree.

Kahlee selects AMD_SOC_CONSOLE_UART causing UART0 to be used as console,
so enable uart_0 in the devicetree to make sure that the UART will be
marked as enabled in the SSDT that will be generated with the next patch
applied. This also matches the other AMD SoC based Chromebooks.

For brya variants with a touchscreen, drive the enable GPIO high
starting in romstage while holding in reset, then disable the reset
GPIO in ramstage (done in the baseboard). This will allow coreboot
to detect the presence of i2c touchscreens during ACPI SSDT generation
(implemented in a subsequent commit).

Before add_io_regions only reported one fixed IO range to the resource
allocator that covered the whole IO range from 0x0000 to 0xffff. Instead
read the data fabric IO space decode base and limit address register
pairs to get the actual IO port decoding from the data fabric registers.
This will also help with adding support for multiple PCI root domains to
the common data fabric domain code so that Genoa can use it. In that
case each PCI root domain will only decode a part of the whole IO port
range.
Beware that the data fabric IO base and limit fields can contain values
that correspond to IO port addresses far outside of the addressable IO
port range. In case of Picasso, the IO limit read from the only enabled
DF IO range register would be 0x1ffffff after converting the raw data to
an IO port address. To not give the resource allocator wrong constraints
make sure that the IO limit we report will be at maximum 0xffff.
TEST=On Mandolin (Picasso) and Birman (Phoenix) the full range of IO
port addresses still gets reported as a domain IO resource producer like
before the patch:
DOMAIN: 0000 io: base: 0 size: 0 align: 0 gran: 0 limit: ffff done

To have both the PCI function number and the register offset into the
config space of that function of the data fabric device in the data
fabric register definitions, introduce and use the DF_REG_ID, DF_REG_FN
and DF_REG_REG macros. The DF_REG_ID macro is used for register
definitions where both the function number and the register offset are
specified, and the DF_REG_FN and DF_REG_REG macros are used to extract
the function number and the register offset from the register defines.
This will allow having one define for accessing an indexed group of
registers that are on different functions of the data fabric device.
TEST=MMIO resources read from the data fabric's MMIO decode registers
don't change on Mandolin and the ACPI CRAT table is also identical.

Debug messages shown during IDE initialization are streamlined as
follows:
"Primary IDE interface" (and similar) are shortened to
"Primary interface".
We don't need to see "IDE" twice as messages are already prefixed.
Refactor "IDE: (Primary) IDE interface: (on)" into
"IDE: (Primary interface): (on)" to allow compiler to deduplicate
component strings, also used later in messages re UDMA/33.
This reduces uncompressed string size by 32 bytes and allows ramstage
to compress a wee bit better.

I don't get around to do proper full reviews of SIO patches since maybe
3 years, so I better remove myself from the maintainers list for that
part of the coreboot tree. If anyone else wants to take this over,
please go ahead. I can still help with some advice and general ideas in
that area, but even the "odd fixes" status that I downgraded the
maintenance status of that sub-tree to some time ago was a bit too
optimistic.

Without setting these GPIO bits, you /can/ power on your board after
powering it down again. This includes after cutting the power.
The only way to recover from this is to pull the CMOS battery and cut
the power for 15mins. Then make sure you don't do this GPIO trickery or
you end up with the same state of basically an unresponsive "dead"
mainboard. So flash the chip before you pull the battery.
One small workaround I found when you like to flash from the system, is
to press the power button with 1 second after you enable power to the
board. In this small timeframe, apparently the superio chip didn't
intialise/restore/gets set with the settings that make it never want to
power on again. The other workaround is to connect the appriopriate
pins on the ATX power connector to force power to the mainboard.
