Edward O'Callaghan bf9f243857 superio/common/conf_mode: Provide another common pnp entry/exit
ITE Super I/O's make use of this method to enter and exit in and out of
their PNP configuration. Provide functions for use in ram stage
component.

Furquan Shaikh 99ac98f7e1 Introduce stage-specific architecture for coreboot
Make all three coreboot stages (bootblock, romstage and ramstage) aware of the
architecture specific to that stage i.e. we will have CONFIG_ARCH variables for
each of the three stages. This allows us to have an SOC with any combination of
architectures and thus every stage can be made to run on a completely different
architecture independent of others. Thus, bootblock can have an x86 arch whereas
romstage and ramstage can have arm32 and arm64 arch respectively. These stage
specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain
and compiler flags for every stage.

These options can be considered as either arch or modes eg: x86 running in
different modes or ARM having different arch types (v4, v7, v8). We have got rid
of the original CONFIG_ARCH option completely as every stage can have any
architecture of its own. Thus, almost all the components of coreboot are
identified as being part of one of the three stages (bootblock, romstage or
ramstage). The components which cannot be classified as such e.g. smm, rmodules
can have their own compiler toolset which is for now set to *_i386. Hence, all
special classes are treated in a similar way and the compiler toolset is defined
using create_class_compiler defined in Makefile.

In order to meet these requirements, changes have been made to CC, LD, OBJCOPY
and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others.
Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the
toolsets are defined using create_class_compiler.

Few additional macros have been introduced to identify the class to be used at
various points, e.g.: CC_$(class) derives the $(class) part from the name of
the stage being compiled.

We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER
as they do not make any sense for coreboot as a whole. All these attributes are
associated with each of the stages.

Edward O'Callaghan cf7b498908 superio/fintek/*: Factor out generic romstage component
The romstage of Fintek Super I/O's is identical, leading to replication
of essentially the same code prone to bitrot. Herein we consolidate the
early pre-ram UART initialisation code into fintek/common, rather we
leave the exceptions to be implemented under model/.

More precisely we provide a well documented version of early_serial.c
under fintek/common and select by way of Kconfig as a generic romstage
component to Super I/O support. We leave future Super I/O's the option
to implement `non-standard` initialisation code should such a (unlikely)
need araise. A primary advantage is that new support for romstage serial
is now trival to add. We also provide some Kconfig documentation while
here.

Christoph Grenz dc92d682ff w83627hf/acpi: Fix logical device power down in ACPI
As Nico noticed for the W83627DHG, the power management bits to power down
individual logical devices on Winbond superios are named counterintuitively
and need to be set when the logical device should be powered.

This corrects the power management methods for the W83627HF.

Damien Zammit 4c2ebeba78 it8728f: Add ITE IT8728F superio early serial support.
This is the first of a series of patches to provide support
for a new mainboard, Gigabyte GA-B75M-D3V.

This patch provides early serial for the superio and has been
tested on this mainboard.  The code is based on IT8718F superio.

Christoph Grenz 2cccacff90 w83627hf/acpi: Fix endianess error in floppy drive enumeration code
The enumeration results are stored as five DWORDs in one 20 byte buffer.
Bytes 3, 7, 11 and 15 were used to set the lowest bit of each DWORD.
ACPI uses little endian, so 1, 4, 8 and 12 are the correct indices.

Nico Huber 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.

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.

Find all the (ramstage) implementations of enter()/exit() functions
for the configuration state, register and call them through the new

pnp_mode_ops, it's not necessary to call enter()/exit() around them

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.

Nico Huber 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.
