Convert all DEBUG_SMBUS, DEBUG_SMI, and DEBUG_RAM_SETUP custom and local #defines into globally configurable kconfig options (and Options.lb options for as long as newconfig still exists) which can be enabled by the user in the "Debugging" menu. The respective menu items only appear if a board is selected where the chipset code actually provides such additional DEBUG output. All three variables default to 0 / off for now. Also, drop a small chunk of dead/useless code in the src/northbridge/via/cn700/raminit.c file, which would otherwise break compilation.

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.

Per default, YABEL only allows option ROMs to access the PCI device

help

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.
