Timothy Pearson 7d8a478e70 device/pci_device: Set bridge primary bus number before scanning
Certain devices, such as the Intel 82575GB, contain multiple nested
PCIe bridges (for example the PES12N3A).  Coreboot does not set
the primary bus number of the lower bridges, causing upstream
forwarding failure.  This in turn causes coreboot to fail to find
the lowest devices (in this case the NICs), and as a result the
required resources are not allocated and the NICs do not function.

Timothy Pearson a693f524ca device/smbus: Avoid infinite loop if SMBUS device has wrong parent
If an SMBUS device in devicetree.cb is placed under a parent device
that does not have an SMBUS controller, coreboot will enter an
infinite loop and hang without printing any failure messages.

Modify the loop to exit under these conditions, allowing the failure
message to be printed.

Nico Huber 8193b068d4 allocator: Page align memory mapped PCI resources
To help hypervisors to assign PCI devices individually to virtualization
guests, page align dynamically allocated MMIO resources.

Tested with kontron/ktqm77 which has dynamically configured onboard
devices on the root bus and secondary buses. Booted Linux and checked
the configuration with `lspci -v`. Got the configuration through Muen's
tools which are very picky about overlapping and alignment. Booted a
Muen based system that uses many onboard devices. GMA, xHCI and one NIC
(on a secondary bus) were verified to function properly.

Aaron Durbin 75c51d9af1 x86: add standalone verstage support
To support x86 verstage one needs a working buffer for
vboot. That buffer resides in the cache-as-ram region
which persists across verstage and romstage. The current
assumption is that verstage brings cache-as-ram up
and romstage tears cache-as-ram down. The timestamp,
cbmem console, and the vboot work buffer are persistent
through in both romstage and verstage. The vboot
work buffer as well as the cbmem console are permanently
destroyed once cache-as-ram is torn down. The timestamp
region is migrated. When verstage is enabled the assumption
is that _start is the romstage entry point. It's currently
expected that the chipset provides the entry point to
romstage when verstage is employed. Also, the car_var_*()
APIs use direct access when in verstage since its expected
verstage does not tear down cache-as-ram. Lastly, supporting
files were added to verstage-y such that an x86 verstage
will build and link.

BUG=chrome-os-partner:44827
BRANCH=None
TEST=Built and booted glados using separate verstage.

Alexandru Gagniuc fdbc1af5e2 Kconfig: Remove EXPERT mode
After much consideration, and many years of an EXPERT mode sitting
almost completely unused, we've seen that it doesn't work for us.
There is no standard on what constitutes EXPERT, and most of
coreboot's options Kconfig are expert-level.

We even joked that not selecting "EXPERT" should prevent coreboot
from compiling:

@echo $(shell whoami) is not permitted to compile coreboot

Kyösti Mälkki cd37a2ba41 devicetree: Rename unused parameter to passthru
The actual use of the parameter max is to keep track of PCI bus
number while recursively scanning PCI bridges or PCI-e rootports.

Neither CPU, SMBus, LPC or other static buses are involved in this
enumeration, but the way bridge operations were originally designed
forced to pass this argument thru unrelated functions.

Follow-up removes these once the function prototype gets fixed.

Kyösti Mälkki d0e212cdce devicetree: Discriminate device ops scan_bus()
Use of scan_static_bus() and tree traversals is somewhat convoluted.
Start cleaning this up by assigning each path type with separate
static scan_bus() function.

For ME, SMBus and LPC paths a bus cannot expose bridges, as those would
add to the number of encountered PCI buses.

Aaron Durbin 899d13d0df cbfs: new API and better program loading
A new CBFS API is introduced to allow making CBFS access
easier for providing multiple CBFS sources. That is achieved
by decoupling the cbfs source from a CBFS file. A CBFS
source is described by a descriptor. It contains the necessary
properties for walking a CBFS to locate a file. The CBFS
file is then decoupled from the CBFS descriptor in that it's
no longer needed to access the contents of the file.

All of this is accomplished using the regions infrastructure
by repsenting CBFS sources and files as region_devices. Because
region_devices can be chained together forming subregions this
allows one to decouple a CBFS source from a file. This also allows
one to provide CBFS files that came from other sources for
payload and/or stage loading.

The program loading takes advantage of those very properties
by allowing multiple sources for locating a program. Because of
this we can reduce the overhead of loading programs because
it's all done in the common code paths. Only locating the
program is per source.

Patrick Georgi 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.

read and the write), so this was of limited value.

Julius Werner 7f70ad610b rk3288: Add software I2C support
This patch adds the necessary platform glue to allow the use of
software-driven I2C bit banging on the RK3288. This is just a debugging
feature that can be used to reproduce certain I2C failure cases.

Also fix Makefile verstage linking for the feature and add some new
rk3288 IOMUX macros as needed.

BRANCH=None
BUG=None
TEST=Added "CONFIG_SOFTWARE_I2C=y" to configs/config.veyron_jerry,
wrapped Jerry's bootblock and verstage in software_i2c_attach/detach()
calls, confirmed that both PMIC and TPM could be driven correctly with
software I2C driver. Tried out different combinations of
software_i2c_wedge_ack() and software_i2c_wedge_read() on the PMIC and
observed transfer results with the hardware controller after reboot...
the worst that would happen is that the first register read-modify-write
(DCDC_ILMAX) would fail to read, but all later transfers would be fine.
Since that register is written twice (due to current BUCK1 ramp
implementation) and is not terribily important anyway, I think we don't
need to worry about wedging problems.
