93064ff7cd device/dram: Inline value into print statement
By default printram() expands to nothing in normal builds, and so
scan-build thinks that the assignment to reg8 is unused. Inline the
value of reg8 into the print statement to silence the warning.

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.

8a41f4b71e device/pci_ops: Move questionable pci_locate() variants
These are defined for __SIMPLE_DEVICE__ when PCI
enumeration has not happened yet. These should not
really try to probe devices other than those on bus 0.

It's hard to track but there maybe cases of southbridge
being located on bus 2 and available for configuration, so
I rather leave the code unchanged. Just move these out of
arch/io.h because they cause build failures if one attempts
to include <arch/pci_ops.h> before <arch/io.h>.

There are two direct copies for ROMCC bootblocks to
avoid inlining them elsewhere.

ad7674ed00 device: Introduce pcidev_on_root() and friends
Semantics of dev_find_slot() are ill in the sense that
it only works after device enumeration has completed in
ramstage. Plan is to declare it as deprecated.

Introduce pcidev_on_root() and pcidev_path_on_root()
functions to replace cases where this was called with
static argument bus == 0. New implementation only walks
the root bus of the PCI tree, while old one walked
the entire linked list of devices.

Introduce pcidev_path_behind() to replace cases where
argument bus != 0. The required parent node is typically
one of the PCIe root functions that you locate using
pcidev_on_root() above.

New forms are safe to use with early devicetree and
before PCI bus numbers have been assigned.

Add the feature for bootblock, verstage and postcar, it
is required with add-on PCIe serial cards for early
console output. It's up to the board specific code to
configure PCIe root port prior to calling console_init()
for this to work.

Remove feature from ramstage, it bypasses any resource
allocations and bus number assignments.

For the moment PCI configuration support before ramstage
is available only on ARCH_X86.

To access the hardware, "simple device" handles are used. These

tree, we use `struct device` pointers. This is referred to as
DEVTREE_EARLY in the code.

This file is about the latter and its name reflects that the

bae9f85ddb devicetree: Add USB device type
This commit adds support for describing USB ports in devicetree.cb.
It allows a USB port location to be described in the tree with
configuration information, and ACPI code to be generated that
provides this information to the OS.

A new scan_usb_bus() is added that will scan bridges for devices so
a tree of ports and hubs can be created.

The device address is computed with a 'port type' and a 'port id'
which is flexible for SOC to handle depending on their specific USB
setup and allows USB2 and USB3 ports to be described separately.

For example a board may have devices on two ports, one with a USB2
device and one with a USB3 device, both of which are connected to an
xHCI controller with a root hub:

     xHCI
       |
    RootHub
    |     |
USB2[0]  USB3[2]

device pci 14.0 on
  chip drivers/usb/acpi
    register "name" = ""Root Hub""
    device usb 0.0 on
      chip drivers/usb/acpi
        register "name" = ""USB 2.0 Port 0""
        device usb 2.0 on end
      end
      chip drivers/usb/acpi
        register "name" = ""USB 3.0 Port 2""
        device usb 3.2 on end
      end
    end
  end
end

9adcbfe486 device/pciexp_device: Set values numerically instead of as bitmask
As noted on linux-pci, we have a weird way to handling "value" and
"scale" fields that are supposed to contain numerical values: we encode
them as a bitfield.
Instead define the two fields (offset and mask) and use numbers.

Another issue, not fixed in this CL, is that we write hard-coded values
while these fields really need to contain the max() of acceptable delays
of the downstream devices. That way the controller can decide whether or
not to enter a deeper power management state. It's noted as a TODO.

f0349023a2 device: further untangle device_t from struct device
This further allows compilation units to be re-used without
having to add macro guards because of declarations not being
around in the __SIMPLE_DEVICE__ case. These declarations are for
functions that operate on struct device. struct device is a known
type so just expose the functions using the correct type. Also,
DEVTREE_CONST is empty while in ramstage so there's no reason
to separate the declarations. Lastly, fix up device_util.c to
use the proper types. It's only compiled in ramstage and it only
operates on struct device.

Move ADD_VBT_DATA_FILE to "Devices" menu and rename it to
INTEL_GMA_ADD_VBT_DATA_FILE.
Depend on Intel platforms to avoid confusing users of non-Intel platforms.

The Intel GMA driver will use the vbt.bin, if present, to fill the
ACPI OpRegion.

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().

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`.

This patch uses struct device explicitly for the ramstage functions
as that's the actual type it's working on. Additionally, the
declarations for types and functions are fully exposed so that
compliation units don't have to guard certain functions from use
because it's being compiled for multiple stages.

2f48b7b1e9 pciexp_device: Remove useless write on a read-only register
The Role-Based Error Reporting is not a configurable field,
it's a read only field in the Device Capability register.
This code was old and comes from commit f6eb88ad but evidently
is not useful in any way. The PCIe Specification [1] states
that it's read-only and must always be set to 1.

I have also done tests on purism/librem13 hardware, trying to
change that value, without any success.

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.

bdb5c8feae coreboot_tables: specify clear interface for lb_framebuffer()

is sitting in src/include/vbe.h while also guarding the call to
fill_lb_framebuffer() with vbe_mode_info_valid() along with some

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().

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.

76f8dbc4f7 device/dram/ddr3: add FTB timings
SPD revision 1.1 introduced FTB timings, an extra set of SPD values that
specify a more precise tCKmin, tAAmin, tRCDmin, tRPmin and tRCmin.

For backwards compatibility, the MTB is usually rounded up and the FTB
part is negative. For this reason some memories were not set up optimally,
as the FTB part was ignored and the resulting timing wasn't set to the
minimum value.

The tests were performed on a Lenovo X220 with two Micron 8KTF51264HZ-1G9E
(1866 MHz): reading only the MTB part, coreboot reports a tCKmin of
1.125 ns, corresponding to a working frequency of 800 MHz; with the
additional tCKmin FTB part (-0.054 ns) the new (rounded) value is
1.070 ns, valid for a 933 MHz operation.

Tested also with Ballistix DDR3-1866 SODIMM on Lenovo T420: the memory is
now detected as DDR3-1866 instead of DDR3-1600.

Some manufacturers (like Micron) seems to expect a small rounding on the
timings, so a nearest-value rounding is performed. If this assumption
isn't correct, an error up to ~2 ps can be committed, which is low enough
to be safely ignored.

91bfa8e7ea PCIEXP_PLUGIN_SUPPORT: Change dependency on PCI access
Some PCI-e capability registers are located starting from
0x100, these are not accessible using the conventional
PCI IO config operations at 0xcf8/0xcfc, unless PCI_CFG_EXT_IO
was selected.

Thus any feature that calls pciexp_find_extended_cap()
depends on either MMCONF_SUPPORT_DEFAULT or PCI_CFG_EXT_IO
being enabled on the platform.

In theory there can be system without MMCONF_SUPPORT, but
with complete PCI Express configuration space available
using PCI_CFG_EXT_IO. Do not use explicit PCI MMCONF
operations here, but rely on the default PCI access
method to be able to access all of the configuration space.

While at it, convert to IS_ENABLED() everywhere in the source
and organize Kconfig file better.

542e9488bd drivers/intel/gma: Hook up libgfxinit
Add `libgfxinit` as another option for native graphics initialization.
For that, the function gma_gfxinit() (see drivers/intel/gma/i915.h) has
to be called by the respective northbridge/soc code.

A mainboard port needs to select `CONFIG_MAINBOARD_HAS_LIBGFXINIT` and
implement the Ada package `GMA.Mainboard` with a single function `ports`
that returns a list of ports to be probed for displays.

v2: Update 3rdparty/libgfxinit to its latest master commit to make
    things buildable within coreboot.

v3: Another update to 3rdparty/libgfxinit. Including support to select
    the I2C port for VGA.

Fix regression with commit:
   7dc4b84 device/dram/ddr3: Calculate CRC16 of SPD unique identifier

Misplaced parenthesis causes CRC check failure, potentially
rendering some platform unbootable.

7dc4b84d8c device/dram/ddr3: Calculate CRC16 of SPD unique identifier
Specification allows for the unique identifier bytes 117..125
to be excluded of CRC calculation. For such SPD, the CRC
would not identify replacement between two identical DIMM parts,
while memory training needs to be redone.

3b87812f00 Kconfig: Update default hex values to start with 0x
Kconfig hex values don't need to be in quotes, and should start with
'0x'.  If the default value isn't set this way, Kconfig will add the
0x to the start, and the entry can be added unnecessarily to the
defconfig since it's "different" than what was set by the default.

A check for this has been added to the Kconfig lint tool.

0325dc6f7c bootmode: Get rid of CONFIG_BOOTMODE_STRAPS
With VBOOT_VERIFY_FIRMWARE separated from CHROMEOS, move recovery and
developer mode check functions to vboot. Thus, get rid of the
BOOTMODE_STRAPS option which controlled these functions under src/lib.
