92da206532 superio/winbond/w83627uhg: Depreciate romstage component
Depreciate the model specific early_serial.c romstage component for this
Super I/O in favor of the recent generic winbond romstage framework.

Convert dependent board to generic winbond serial init. Note the clock
function is actually invalid since it never enters into PNP config mode
to twiddle the register. Further, 48MHz is the default (page 9 of
data-sheet) and so romstage.c need not do anything to the clock rate
hence why it presumably works with this invalid function.

def00be41d src/drivers/pc80: Remove empty struct keyboard
This is a empty struct that has propagated through the superio's & ec's
but really does nothing. Time to get rid of it before it adds yet more
cruft. However, since this touches many superio's at once we do this in
stages by first changing the function type to be a pure procedure.

6c6acd79a0 superio: Uncomment the w83627uhg UART clock source initialization
The asrock/imb-a180 mainboard is the first mainboard to use this
w83627uhg/nct6627UD sio. The default h/w clock setting is 0. Adding
the SIO in the mainboard Kconfig made the builder complain that the
set_uart_clock_source() wasn't being used. So the calls to that function
were uncommented.

7037840ece w83627hf/acpi: Move floppy drive enumeration from _INI into _FDE.
Move the floppy drive enumeration from _INI() and PROB(),
which stored the enumeration results into _FDE into _FDE().
_INI is called by any ACPI-capable OS on boot while _FDE
is rarely used. So it's better to run the enumeration when
requested rather than unconditionally.

bbf096911d w83627hf/acpi: Make AddressMax a multiple of AddressAlignment
The parallel port of the W83627HF can be configured on any port
between 0x100 and 0xFFC with 4 byte alignment for traditional modes
and 8 byte alignment for EPP mode. As the ACPI specification says
that the maximum acceptable starting address has to be a multiple
of the alignment granularity, correct the maximum starting address
from 0xFFC to 0xFF8.

dd94fa93b4 winbond/w83627dhg: Fix logical device power down in ACPI
The W83627DHG has some power managements bits to power down individual
logical devices. These are called `* Power Down`. Counterintuitively and
in contrast to `Immediate Power Down` (bit to power down the whole chip),
these bits are set when the respective logical device is powered.

Unfortunately, our ACPI code set them wrong which led to disabled
devices after a S3 suspend/resume. Adding an option how to set the PM
bits and setting them to zero for the W83627DHG, corrects it.

Tested with kontron/ktqm77.

cacc58a874 winbond/w83627dhg: Correct resource setting for SPI (LDN6)
The SPI logical device on the W83627DHG uses the second i/o port
register pair but not the first one. So we have to also set `io1`
(the second io_info struct) and not `io0` in the pnp_info structure.

Setting the PNP_IO1 flag without a mask in `io1` caused coreboot to
hang in pnp_enable_devices() until commit aeead274 which added a
check for an unset mask.

13dc976a52 pnp: Register implementations of enter/exit config state
Find all the (ramstage) implementations of enter()/exit() functions
for the configuration state, register and call them through the new
struct pnp_mode_ops. As our standard PnP functions are aware of the
pnp_mode_ops, it's not necessary to call enter()/exit() around them
anymore.

Patch generated with the cocci below. It's not perfect. The movement
of the enter()/exit() calls is somehow fragile. So I checked the
remaining calls for sense, and changed some empty lines. Also a
duplicate insertion of pnp_conf_mode_ops had to be removed.

f898f7ba4d pnp: Provide alternative pnp_enable() implementation
The current default implementation of pnp_enable() only disables devices
- if set so in the devicetree - but does not enable them. Enablement takes
place in pnp_enable_resources(). Yet, many PnP chips implement their own
version of pnp_enable() which also enables devices if set in the devicetree.

It's arguable, if enabling those devices makes sense, before they get
resources assigned. Maybe we can't write the resource registers if not,
who knows? The least we can do is providing a common implementation for
this behavior, and get rid of some code duplication.

Used the following cocci:

24d1d4b472 x86: Unify arch/io.h and arch/romcc_io.h
Here's the great news: From now on you don't have to worry about
hitting the right io.h include anymore. Just forget about romcc_io.h
and use io.h instead. This cleanup has a number of advantages, like
you don't have to guard device/ includes for SMM and pre RAM
anymore. This allows to get rid of a number of ifdefs and will
generally make the code more readable and understandable.

Potentially in the future some of the code in the io.h __PRE_RAM__
path should move to device.h or other device/ includes instead,
but that's another incremental change.

one (tested for all 32-bit signed integers :-) and takes about 10 ns
to run as opposed to 5ns for the non-portable assembly version. While speed
is good, I think we can spare the 15 ns or so we add to boot time
by using the C version only.
