The reloctable ramstage support allows for the ramstage to be built
 +
as a relocatable module. The stage loader can identify a place
 +
out of the OS way so that copying memory is unnecessary during an S3

A current limitation of NEM (Non-Evict mode) is that code and data sizes

With NEM, if there is no physical memory behind the cached area,

the modified data will be lost and NEM results will be inconsistent.

The haswell romstage code caches the loaded ramstage program

Although the Intel manual says you must set the lock bit in addition

we have the option to leave it unlocked and allow the OS (e.g. Linux)

The microcode file may be removed from the ROM image at a later

 +
 
 +
A word of caution: only select this option if you are sure the

coreboot.

Note that for some CPUs, the microcode is hard-coded into the source

tree and is not loaded from CBFS. In this case, microcode will still
 +
be updated. There is a push to move all microcode to CBFS, but this
 +
change is not implemented for all CPUs.
 +
 
 +
This option currently applies to:
 +
- Intel SandyBridge/IvyBridge

- VIA Nano

Microcode may be added to the ROM image at a later time with cbfstool,
 +
if desired.
 +
 
 +
If unsure, select "Generate from tree"
 +
 
 +
The GOOD:
 +
Microcode updates intend to solve issues that have been discovered
 +
after CPU production. The expected effect is that systems work as
 +
intended with the updated microcode, but we have also seen cases where
 +
issues were solved by not applying microcode updates.
 +
 
 +
The BAD:
 +
Note that some operating system include these same microcode patches,
 +
so you may need to also disable microcode updates in your operating
 +
system for this option to have an effect.
 +
 
 +
The UGLY:
 +
A word of CAUTION: some CPUs depend on microcode updates to function
 +
correctly. Not updating the microcode may leave the CPU operating at
 +
less than optimal performance, or may cause outright hangups.
 +
There are CPUs where coreboot cannot properly initialize the CPU
 +
without microcode updates
 +
For example, if running with the factory microcode, some Intel
 +
SandyBridge CPUs may hang when enabling CAR, or some VIA Nano CPUs
 +
will hang when changing the frequency.
 +
 
 +
Make sure you have a way of flashing the ROM externally before

selecting this option.

If you don't have an Intel Firmware Descriptor (descriptor.bin) for your

 +
The resulting coreboot.rom will not contain all parts required

to get coreboot running on your board. You can however write only the

untouched. Unfortunately the current version of flashrom doesn't

The Intel Firmware Descriptor supports preventing write accesses

with an external SPI flash programmer. You will want this if you

Disable the platform heirarchy on resume path if the firmware

 +
This option is auto selected if CHROMEOS because it matches with

| VGA_ROM_RUN || device || bool || Run VGA Option ROMs ||
 +
Execute VGA Option ROMs in coreboot if found. This can be used
 +
to enable PCI/AGP/PCI-E video cards when not using a SeaBIOS
 +
payload.
 +
 
 +
When using a SeaBIOS payload it runs all option ROMs with much

more complete BIOS interrupt services available than coreboot,

which some option ROMs require in order to function correctly.
 +
 
 +
||

Some platforms (e.g. Intel Braswell and Skylake/Kaby Lake) support

such a blob.

Select this to not perform any graphics initialization in

Execute VGA Option ROMs in coreboot when resuming from S3 suspend.
 +
 
 +
When using a SeaBIOS payload it runs all option ROMs with much

more complete BIOS interrupt services available than coreboot,

which some option ROMs require in order to function correctly.

If unsure, say N when using SeaBIOS as payload, Y otherwise.

Always load option ROMs if any are found. The decision to run

the ROM is still determined at runtime, but the distinction

between loading and not running comes into play for CHROMEOS.
 +
 
 +
An example where this is required is that VBT (Video BIOS Tables)

are needed for the kernel's display driver to know how a piece of

hardware is configured to be used.

| ON_DEVICE_ROM_LOAD || device || bool || Load Option ROMs on PCI devices ||

Load Option ROMs stored on PCI/PCIe/AGP VGA devices in coreboot.
 +
 
 +
If disabled, only Option ROMs stored in CBFS will be executed by
 +
coreboot. If you are concerned about security, you might want to
 +
disable this option, but it might leave your system in a state of
 +
degraded functionality.
 +
 
 +
When using a SeaBIOS payload it runs all option ROMs with much

more complete BIOS interrupt services available than coreboot,

| PCI_OPTION_ROM_RUN_REALMODE || device || bool || Native mode ||
 +
If you select this option, PCI Option ROMs will be executed
 +
natively on the CPU in real mode. No CPU emulation is involved,
 +
so this is the fastest, but also the least secure option.
 +
(only works on x86/x64 systems)
 +
 
 +
||
 +
|- bgcolor="#eeeeee"
 +
| PCI_OPTION_ROM_RUN_YABEL || device || bool || Secure mode ||
 +
If you select this option, the x86emu CPU emulator will be used to
 +
execute PCI Option ROMs.
 +
 
 +
This option prevents Option ROMs from doing dirty tricks with the
 +
system (such as installing SMM modules or hypervisors), but it is
 +
also significantly slower than the native Option ROM initialization
 +
method.
 +
 
 +
This is the default choice for non-x86 systems.
 +
 
 +
||
 +
|- bgcolor="#eeeeee"
 +
| YABEL_PCI_ACCESS_OTHER_DEVICES || device || bool || Allow Option ROMs to access other devices ||
 +
Per default, YABEL only allows Option ROMs to access the PCI device
 +
that they are associated with. However, this causes trouble for some
 +
onboard graphics chips whose Option ROM needs to reconfigure the
 +
north bridge.
 +
 
 +
||
 +
|- bgcolor="#eeeeee"
 +
| YABEL_PCI_FAKE_WRITING_OTHER_DEVICES_CONFIG || device || bool || Fake success on writing other device's config space ||
 +
By default, YABEL aborts when the Option ROM tries to write to other
 +
devices' config spaces. With this option enabled, the write doesn't
 +
follow through, but the Option ROM is allowed to go on.
 +
This can create issues such as hanging Option ROMs (if it depends on
 +
that other register changing to the written value), so test for
 +
impact before using this option.
 +
 
 +
||
 +
|- bgcolor="#eeeeee"
 +
| YABEL_VIRTMEM_LOCATION || device || hex || Location of YABEL's virtual memory ||
 +
YABEL requires 1MB memory for its CPU emulation. This memory is
 +
normally located at 16MB.
 +
 
 +
||
 +
|- bgcolor="#eeeeee"
 +
| YABEL_DIRECTHW || device || bool || Direct hardware access ||
 +
YABEL consists of two parts: It uses x86emu for the CPU emulation and
 +
additionally provides a PC system emulation that filters bad device
 +
and memory access (such as PCI config space access to other devices
 +
than the initialized one).
 +
 
 +
When choosing this option, x86emu will pass through all hardware
 +
accesses to memory and I/O devices to the underlying memory and I/O
 +
addresses. While this option prevents Option ROMs from doing dirty
 +
tricks with the CPU (such as installing SMM modules or hypervisors),
 +
they can still access all devices in the system.
 +
Enable this option for a good compromise between security and speed.

switch to text mode before handing control to a payload.

This option keeps the framebuffer mode set after coreboot finishes

In the above example 1106 is the PCI vendor ID (in hex, but without

| USBDEBUG || drivers/usb || bool || USB 2.0 EHCI debug dongle support ||
 +
This option allows you to use a so-called USB EHCI Debug device
 +
(such as the Ajays NET20DC, AMIDebug RX, or a system using the
 +
Linux "EHCI Debug Device gadget" driver found in recent kernel)
 +
to retrieve the coreboot debug messages (instead, or in addition
 +
to, a serial port).
 +
 
 +
This feature is NOT supported on all chipsets in coreboot!
 +
 
 +
It also requires a USB2 controller which supports the EHCI
 +
Debug Port capability.
 +
 
 +
See https://www.coreboot.org/EHCI_Debug_Port for an up-to-date list
 +
of supported controllers.

Some boards have multiple EHCI controllers with possibly only

 +
Mapping of this index to PCI device functions is southbridge

specific and mainboard level Kconfig should already provide

a working default value here.

Setting of 0 means to scan possible ports starting from 1.
 +
 
 +
Intel platforms have hardwired the debug port location and this
 +
setting makes no difference there.
 +
 
 +
Hence, if you select the correct port here, you can speed up
 +
your boot time. Which USB port number refers to which actual
 +
port on your mainboard (potentially also USB pin headers on
 +
your mainboard) is highly board-specific, and you'll likely

have to find out by trial-and-error.
