8db31a8f4e PCI ops: Remove conflicting duplicate declarations
The code originates from times before __SIMPLE_DEVICE__ was
introduced. To keep behaviour unchanged, use explicit PCI
IO operations here.

448e386309 drivers/pc80: Add PS/2 mouse presence detect
On certain Winbond SuperIO devices, when a PS/2 mouse is not
present on the auxiliary channel both channels will cease to
function if the auxiliary channel is probed while the primary
channel is active.  Therefore, knowledge of mouse presence
must be gathered by coreboot during early boot, and used to
enable or disable the auxiliary PS/2 port before control is
passed to the operating system.

Add auxiliary channel PS/2 device presence detect, and update
the Winbond W83667HG-A driver to flag the auxiliary channel as
disabled if no device was detected.

8a13743569 x86 chipsets: Link non-code flow CHIPSET_BOOTBLOCK_INCLUDE files
Non-code flow assembly stubs do not have to be included in
bootblock.S, now that we have more freedom in bootblock linking.
Rather than bringing these stubs to the config system, just link them
in the bootblock.

Note that we cannot fully remove CHIPSET_BOOTBLOCK_INCLUDE at this
point, as some intel SOCs use this stub for code flow.

objdump -h build/cbfs/fallback/bootblock.debug on a few random boards
confirms that the appropriate sections are still included in the
final binary.

72bb66eb9c x86/bootblock: Use LDFLAGS_bootblock to enable garbage collection
The x86 bootblock linking is a mess. The bootblock is treated in
a very special manner, and never received the update to link-time
garbage collection.

On newer x86 platforms, the boot media is no longer memory-mapped.
That means we need to do a lot more setup in the bootblock. ROMCC is
unsuitable for this task, and walkcbfs only works on memory-mapped
CBFS. We need to revise the x86 bootflow for this new case.

The approach this patch series takes is to perform CAR setup in the
bootblock, and load the following stage (either romstage or verstage)
from the boot media. This approach is not new, but has been done on
our ARM ports for years.

Since we will be adding .c files to the bootblock, it is prudent to
use link-time garbage collection. This is also consistent to how we
do things on other architectures. Unification FTW!

3953e3947d x86: bootblock: remove linking and program flow from build system
The build system was previously determining the flow
and linking scripts bootblock code by the order of files
added to the bootblock_inc bootblock-y variables.Those
files were then concatenated together and built by a myriad of
make rules.

Now bootblock.S and bootblock.ld is added so that bootblock
can be built and linked using the default build rules.
CHIPSET_BOOTBLOCK_INCLUDE is introduced in order to allow the
chipset code to place include files in the path of the bootblock
program -- a replacement for the chipset_bootblock_inc
make variable.

b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

13e4182119 kbuild: automatically include southbridges
This change switches all southbridge vendors and southbridges
to be autoincluded by Makefile.inc, rather than having to be
mentioned explicitly in southbridge/Makefile.inc or in
southbridge/<vendor>/Makefile.inc.

In order to be able to drop southbridge/amd/Makefile.inc, some
scattered source files had to be moved to a southbridge/amd/common
directory, in accordance to what we are doing on other architectures
already.

This means, vendor and southbridge directories are now "drop
in", e.g. be placed in the coreboot directory hierarchy
without having to modify any higher level coreboot files.

The long term plan is to enable out of tree components to be
built with a given coreboot version (given that the API did not
change).

5ab52ddc3d southbridge: Drop print_ implementation from non-romcc boards
Because we had no stack on romcc boards, we had a separate, not as
powerful clone of printk: print_*. Back in the day, like more than
half a decade ago, we migrated a lot of boards to printk, but we never
cleaned up the existing code to be consistent. instead, we worked around
the problem with a very messy console.h (nowadays the mess is hidden in
romstage_console.c and early_print.h)
This patch cleans up the southbridge code to use printk() on all non-ROMCC
boards.

b3f08c61f1 cmos: Rename the CMOS related functions.
Most of the code related to the mc146818 is not related to the RTC and is
really for managing the CMOS storage. Since we intend to add a generic API
for RTC drivers it's inconvenient for those functions to have an rtc_ prefix.
This CL renames those functions so they start with cmos_ instead. There are
some places where rtc_init was called with a comment that says something about
starting the RTC. That wasn't correct before (the RTC is always running), but
it looks a little odd now that the function is called cmos_init.

This CL also opportunistically cleans up some style problems in this file.

b32816e9a5 Remove PCI_ROM_RUN option
The main purpose of option rom is to supply int* handlers.
But supplying those is outside of coreboot scope and if someone needs those
they should run SeaBIOS anyway which runs the option roms wonderfully.

Running VGA oprom is kept because they're needed to init graphics.

This patch still keeps the options to include the option roms to make them
available to SeaBIOS.

ac16405799 usbdebug: Fix boards without EARLY_CBMEM_INIT
The main usbdebug file lib/usbdebug.c was removed from romstage
build with commit f8bf5a10 but the chipset-specific parts were not,
leading to unresolved symbol errors for AMD platforms.

Add a silent Kconfig variable USBDEBUG_IN_ROMSTAGE for convenient
use of this feature.

8101aa6bb0 usbdebug: Support choice of EHCI controller
Nowadays, chipsets or boards do not only have one USB port with the
capabilities of a debug port but several ones. Some of these ports are
easier accessible than others, so making them configurable is also necessary.
This change adds infrastructure to switch between EHCI controllers,
but does not implement it for any chipset.

2410010018 usbdebug: Change debug port scanning
On AMD platforms, setting of USBDEBUG_DEFAULT_PORT=0 tries to scan
all physical ports one after other in incrementing order. To avoid
possible problems with other USB devices, one can select the port
number here and bypass the scan.

Intel platforms can communicate with usbdebug dongle on one
physical port only, and this option makes no difference there.

fb387dfb92 usbdebug: Drop duplicates of EHCI BAR relocation code
All the additional work that needs to be done in EHCI BAR relocation
is independent of the hardware platform and was functionally identical
in all the copies removed.

When USBDEBUG is not selected, PCI EHCI controllers use standard
pci_dev_read_resources() call.

With USBDEBUG selected, PCI EHCI controller's device_operations
.read_resources is replaced with pci_ehci_read_resources() call,
which in turn will replace the device_operations .set_resources call.
The replacement for .set_resources reconfigures usbdebug driver side,
and calls the original .set_resources to configure hardware side.

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.

5079a0d32f Remove assembly coded log2 function
As we move to supporting other systems we need to get rid of assembly
where we can. The log2 function in src/lib is identical to the assembly
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.

23f38cd05c Get rid of drivers class
The use of ramstage.a required the build system to handle some
object files in a special way, which were put in the drivers
class.

These object files didn't provide any symbols that were used
directly (but only via linker magic), and so the linker never
considered them for inclusion.

With ramstage.a gone, we can drop this special class, too.
