3f98d41b6e device/pci_ops: Make PCI_BDF() available in all stages
Caller needs to take into account that bus numbers may
have not been assigned yet. Same issue existed before
with early ramstage and mostly does not cause problems
when used with static devices on bus 0.

db7a3ae863 src/device/oprom: Fix bootsplash display code for optionroms
So far the bootsplash is only correctly rendered if the framebuffer is
set up as 1024x768@16.
Different resolutions did not show anything, differnent depth resulted
in the distorted images.

This commit removes this limit by using the actual framebuffer resolutions
and combines the code for x86 and yabel.

For the moment the bootsplash is still limited to VGA-OptionROM
framebuffer init.

It was tested in 1280x1024@32 on the wip razer blade stealth using the
intel vgabios.

c76bfac088 device/oprom/realmode: Add vbe return status support as per VBE spec 3.0
Existing coreboot oprom implementation relies on user selected
vesa mode through CONFIG_FRAMEBUFFER_VESA_MODE Kconfig option
and expects that all oprom might support user selected vesa mode.

Take an example:
Enabling AMD external radeon PCIE graphics card on ICLRVP with
default vesa mode 0x118. Unable to get valid X and Y resolution
after executing vbe_get_mode_info() with 0x4118, return data
buffer shows 0x0 resolution. It causes further hang while trying
to draw bmpblk image at depthcharge.

This patch checks for output register AH in all vbe function
(0x3 and 0x4f00/1/2) and die() if returns error.

807803afa2 vboot: remove OPROM-related code
As of CL:1605641, vboot2 code should be used for setting and
checking display init state.  Remove all vboot1 OPROM-related
code, and use the vboot2 display init code which has already
been added in previous commits.

coreboot should not be reading vboot NVRAM flags directly.
Remove the function vboot_wants_oprom(), and instead rely on
display_init_required(), which uses the
VBOOT_WD_FLAG_DISPLAY_INIT value stored in
vboot_working_data.flags, initialized during verstage.
Note that this means in the case of CONFIG_VBOOT=y, the return
value of display_init_required() can only be trusted after
verstage has been executed.  This should not be a problem
assuming that all display initialization occurs in ramstage.

d2cdfff63b device/pci: Rewrite PCI MMCONF with symbol reference
The effect of pointer aliasing on writes is that any data on CPU
registers that has been resolved from (non-const and non-volatile)
memory objects has to be discarded and resolved. In other words, the
compiler assumes that a pointer that does not have an absolute value
at build-time, and is of type 'void *' or 'char *', may write over
any memory object.

Using a unique datatype for MMIO writes makes the pointer to _not_
qualify for pointer aliasing with any other objects in memory. This
avoid constantly resolving the PCI MMCONF address, which is a derived
value from a 'struct device *'.

6d9c131061 vboot: Change oprom checks to CONFIG_VBOOT, assert OPROM_MATTERS
Skipping display init on normal-mode boot is a vboot feature, not
specific to Chrome OS. Fix the code in display_init_required() and
pci_dev_init() to check CONFIG_VBOOT rather than CONFIG_CHROMEOS now
that the two aren't always the same anymore.

Also add a check to guarantee at compile time that
CONFIG_VBOOT_OPROM_MATTERS is enabled on all platforms that make a check
to this function (when CONFIG_VBOOT is also enabled). The whole display
skipping mechanism is based on the oprom_needed NVRAM flag, and skipping
display init without enabling the option to tell vboot that it needs to
pay attention to that flag would make the whole thing not work right.
