Kyösti Mälkki 9ab1c106c3 device: Conditionally bypass oprom execution
Builds with CHROMEOS can bypass VGA oprom when boot is not in
developer or recovery modes. Have the same functionality available
without CHROMEOS but with BOOTMODE_STRAPS.

Kyösti Mälkki ab56b3b11c ChromeOS: Remove oprom_is_loaded
A global flag oprom_is_loaded was used to indicate to
U-boot that VGA option ROM was loaded and run, or that
native VGA init was completed on GMA device.

Implement this feature without dependency to CHROMEOS option
and replace use of global variable oprom_is_loaded with call
to gfx_get_init_done().

Kyösti Mälkki 580e5642a8 device: provide option to always load PCI option roms
Certain kernel drivers require the presence of option rom
contents because the board's static configuration information
is located within the blob. Therefore, allow a chipset/board to
instruct the pci device handling code to always load but not
necessarily run the option rom.

BUG=chrome-os-partner:25885
BRANCH=baytrail
TEST=Both enabling and not enabling this option shows expected behavior.

Vladimir Serbinenko 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.

Duncan Laurie cb73a8410c Clean up POST codes for Boot State machine
Now that there is a clearly defined boot state machine
we can add some useful post codes to indicate the current
point in the state machine by having it log a post code
before the execution of each state.

This removes the currently defined POST codes that were
used by hardwaremain in favor of a new contiguous range
that are defined for each boot state.

The reason for this is that the existing codes are mostly
used to indicate when something is done, which is confusing
for actual debug because POST code debugging relies on knowing
what is about to happen (to know what may be at fault) rather
than what has just finished.

One additonal change is added during device init step as this
step often does the bulk of the work, and frequently logs POST
codes itself.  Therefore in order to keep better track of what
device is being initialized POST_BS_DEV_INIT is logged before
each device is initialized.

interrupted boot with reset button and
gathered the eventlog.  Mosys has been extended to
decode the well-known POST codes:

Duncan Laurie 8adf7a2c50 Log device path into CMOS during probe stages
One of the most common hangs during coreboot execution
is during ramstage device init steps.  Currently there
are a set of (somewhat misleading) post codes during this
phase which give some indication as to where execution
stopped, but it provides no information on what device
was actually being initialized at that point.

This uses the new CMOS "extra" log banks to store the
encoded device path of the device that is about to be
touched by coreboot.  This way if the system hangs when
talking to the device there will be some indication where
to investigate next.

Marc Jones 2a58ecde78 Add new finalize functions for devices and chips
Many chipset devices require additional configuration after
device init. It is not uncommmon for a device early in the devicetree
list to need to change a setting after a device later in the tree does
PCI init. A final function call has been added to device ops to handle
this case. It is called prior to coreboot table setup.

Another problem that is often seen is that the chipset or mainboard
need to do some final cleanup just before loading the OS. The chip
finalize has been added for this case. It is call after all coreboot
tables are setup and the payload is ready to be called.

Similar functionality could be implemented with the hardwaremain
states, but those don't fit well in the device tree function pointer
structure and should be used sparingly.

Ronald G. Minnich b2893a0169 Provide support for setting up the framebuffer from EDID
Add three functions to edid.c:

void set_vbe_mode_info_valid(struct edid *edid, uintptr_t fb_addr)
takes an edid and uintptr_t, and fills in a static lb_framebuffer struct
as well as setting the static vbe_valid to 1 unless some problem
is found in the edid. The intent here is that this could be called from
the native graphics setup code on both ARM and x86.

int vbe_mode_info_valid(void)
returns value of the static vbe_valid.

void fill_lb_framebuffer(struct lb_framebuffer *framebuffer)
copies the static edid_fb to lb_framebuffer.

There is now a common vbe.h in src/include, removed the two special ones.

In general, graphics in coreboot is a mess, but graphics is always a
mess.  We don't have a clean way to try two different ways to turn on
a device and use the one that works. One battle at a time. Overall,
things are much better.

The best part: this code would also work for ARM, which also uses EDID.

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.

This patch was made by listenning to what Ron Minnich told
  me to do on #coreboot IRC channel on Freenode with my
  adaptations on top.

i915tool is at https://code.google.com/p/i915tool/ ,
  the one in coreboot is outdated.

Alexandru Gagniuc 78706fd61f DDR3: Add utilities for creating MRS commands
MRS commands are used to tell the DRAM chip what timing and what
termination and drive strength to use, along with other parameters.
The MRS commands are defined by the DDR3 specification [1]. This
makes MRS commands hardware-independent.

MRS command creation is duplicated in various shapes and forms in any
chipset that does DDR3. This is an effort to create a generic MRS API
that can be used with any chipset.

This is used in the VX900 branch.

Aaron Durbin a146d58ca0 ramstage: prepare for relocation
The current ramstage code contains uses of symbols that cause issues
when the ramstage is relocatable. There are 2 scenarios resolved by this
patch:

1. Absolute symbols that are actually sizes/limits. The symbols are
   problematic when relocating a program because there is no way to
   distinguish a symbol that shouldn't be relocated and one that can.
   The only way to handle these symbols is to write a program to post
   process the relocations and keep a whitelist of ones that shouldn't
   be relocated. I don't believe that is a route that should be taken
   so fix the users of these sizes/limits encoded as absolute symbols
   to calculate the size at runtime or dereference a variable in memory
   containing the size/limit.

2. Absoulte symbols that were relocated to a fixed address. These
   absolute symbols are generated by assembly files to be placed at a
   fixed location. Again, these symbols are problematic because one
   can't distinguish a symbol that can't be relocated. The symbols
   are again resolved at runtime to allow for proper relocation.

For the symbols defining a size either use 2 symbols and calculate the
difference or provide a variable in memory containing the size.

Ronald G. Minnich 69efaa0388 Google Link: Add remaining code to support native graphics
The Link native graphics commit 49428d84 [1]

    Add support for Google's Chromebook Pixel

was missing some of the higher level bits, and hence could not be
used.  This is not new code -- it has been working since last
August -- so the effort now is to get it into the tree and structure
it in a way compatible with upstream coreboot.

1. Add options to src/device/Kconfig to enable native graphics.
2. Export the MTRR function for setting variable MTRRs.
3. Clean up some of the comments and white space.

While I realize that the product name is Pixel, the mainboard in the
coreboot tree is called Link, and that name is what we will use
in our commits.

Hung-Te Lin 6fe0cab205 Extend CBFS to support arbitrary ROM source media.
Summary:
	Isolate CBFS underlying I/O to board/arch-specific implementations as
	"media stream", to allow loading and booting romstage on non-x86.

	CBFS functions now all take a new "media source" parameter; use
	CBFS_DEFAULT_MEDIA if you simply want to load from main firmware.
	API Changes:
		cbfs_find => cbfs_get_file.
		cbfs_find_file => cbfs_get_file_content.
		cbfs_get_file => cbfs_get_file_content with correct type.

CBFS used to work only on memory-mapped ROM (all x86). For platforms like ARM,
the ROM may come from USB, UART, or SPI -- any serial devices and not available
for memory mapping.

To support these devices (and allowing CBFS to read from multiple source
at the same time), CBFS operations are now virtual-ized into "cbfs_media".  To
simplify porting existing code, every media source must support both "reading
into pre-allocated memory (read)" and "read and return an allocated buffer
(map)". For devices without native memory-mapped ROM, "cbfs_simple_buffer*"
provides simple memory mapping simulation.

Every CBFS function now takes a cbfs_media* as parameter. CBFS_DEFAULT_MEDIA
is defined for CBFS functions to automatically initialize a per-board default
media (CBFS will internally calls init_default_cbfs_media).  Also revised CBFS
function names relying on memory mapped backend (ex, "cbfs_find" => actually
loads files). Now we only have two getters:
	struct cbfs_file *entry = cbfs_get_file(media, name);
	void *data = cbfs_get_file_content(CBFS_DEFAULT_MEDIA, name, type);

Test results:
 - Verified to work on x86/qemu.
 - Compiles on ARM, and follow up commit will provide working SPI driver.
