Aamir Bohra 2188f57a80 src/device: Update LTR configuration scheme
This patch moves out LTR programming under L1 substate
to pchexp_tune_device function, as substate programming
and LTR programming are independent.

LTR programming scheme is updated to scan through entire
tree and enable LTR mechanism on pci device if LTR mechanism
is supported by device.

BRANCH=none
BUG=b:66722364
TEST=Verify LTR is configured for end point devices and max
snoop latency gets configured.

Bill XIE c8050f4bfc device/dram/ddr2.c: fix a hidden syntax error introduced earlier
A regression is hidden in commit 7eb0157fca
(device/dram/ddr2.c: Decoding byte[12] bit7 as self refresh flag ), which
breaks the build procedure when CONFIG_DEBUG_RAM_SETUP is set.

Maybe it had better implement "printram" and the like as inline
functions instead of macros.

Nico Huber 581738642f Reinvent I2C ops
Do not use the global platform_i2c_transfer() function that can only be
implemented by a single driver. Instead, make a `struct device` aware
transfer() function the only interface function for I2C controller dri-
vers to implement.

To not force the slave device drivers to be implemented either above
generic I2C or specialized SMBus operations, we support SMBus control-
lers in the slave device interface too.

We start with four simple slave functions: i2c_readb(), i2c_writeb(),
i2c_readb_at() and i2c_writeb_at(). They are all compatible to respec-
tive SMBus functions. But we keep aliases because it would be weird to
force e.g. an I2C EEPROM driver to call smbus_read_byte().

Nico Huber 029dfff30c i2c: Move to Linux like `struct i2c_msg`
Our current struct for I2C segments `i2c_seg` was close to being compa-
tible to the Linux version `i2c_msg`, close to being compatible to SMBus
and close to being readable (e.g. what was `chip` supposed to mean?) but
turned out to be hard to fix.

Instead of extending it in a backwards compatible way (and not touching
current controller drivers), replace it with a Linux source compatible
`struct i2c_msg` and patch all the drivers and users with Coccinelle.

The new `struct i2c_msg` should ease porting drivers from Linux and help
to write SMBus compatible controller drivers.

Beside integer type changes, the field `read` is replaced with a generic
field `flags` and `chip` is renamed to `slave`.

Patched with Coccinelle using the clumsy spatch below and some manual
changes:

* Nested struct initializers and one field access skipped by Coccinelle.
* Removed assumption in the code that I2C_M_RD is 1.
* In `i2c.h`, changed all occurences of `chip` to `slave`.

Nico Huber 2e7f6ccafc fsp/gop: Add running the GOP to the choice of gfx init
The new config choice is called RUN_FSP_GOP. Some things had to happen
on the road:

  * Drop confusing config GOP_SUPPORT,
  * Add HAVE_FSP_GOP to chipsets that support it,
  * Make running the GOP an option for FSP2.0 by returning 0
    in random VBT getters.

Nico Huber d4ebeaf475 device/Kconfig: Put gfx init methods into a `choice`
Provide all gfx init methods as a Kconfig `choice`. This elimates the
option to select native gfx init along with running a Video BIOS. It's
been only theoretically useful in one corner case: Hybrid graphics
where only one controller is supported by native gfx init. Though I
suppose in that case it's fair to assume that one would use SeaBIOS to
run the VBIOS.

For the case that we want the payload to initialize graphics or no
pre-boot graphics at all, the new symbol NO_GFX_INIT was added to the
choice. If multiple options are available, the default is chosen as
follows:

  * NO_GFX_INIT, if we add a Video BIOS and the payload is SeaBIOS,
  * VGA_ROM_RUN, if we add a Video BIOS and the payload is not SeaBIOS,
  * NATIVE_VGA_INIT, if we don't add a Video BIOS.

As a side effect, libgfxinit is now an independent choice.

For some reason the "interface" for adding framebuffer information
is sitting in src/include/vbe.h while also guarding the call to
fill_lb_framebuffer() with vbe_mode_info_valid() along with some
macro if CONFIG_* for good measure.

Move the fill_lb_framebuffer() declaration to coreboot_tables.h and
provide a comment about how it should be used. Also, now that
there's no need for the notion of a global vbe_mode_info_valid()
remove it from the conditional call path of fill_lb_framebuffer().

Aaron Durbin e4d7abc0d4 lib: provide clearer devicetree semantics
The devicetree data structures have been available in more than just
ramstage and romstage. In order to provide clearer and consistent
semantics two new macros are provided:

1. DEVTREE_EARLY which is true when !ENV_RAMSTAGE
2. DEVTREE_CONST as a replacment for ROMSTAGE_CONST

The ROMSTAGE_CONST attribute is used in the source code to mark
the devicetree data structures as const in early stages even though
it's not just romstage. Therefore, rename the attribute to
DEVTREE_CONST as that's the actual usage. The only place where the
usage was not devicetree related is console_loglevel, but the same
name was used for consistency. Any stage that is not ramstage has
the const C attribute applied when DEVTREE_CONST is used.
