Selected by mainboards that use native graphics initialization
for the LVDS port. A linear framebuffer is only supported for
LVDS.
config MMCONF_BASE_ADDRESS
hex
default 0xf0000000
config OVERRIDE_CLOCK_DISABLE
bool
default n
help
Usually system firmware turns off system memory clock
signals to unused SO-DIMM slots to reduce EMI and power
consumption.
However, some boards do not like unused clock signals to
be disabled.
config MAXIMUM_SUPPORTED_FREQUENCY
int
default 0
help
If non-zero, this designates the maximum DDR frequency
the board supports, despite what the chipset should be
capable of.
config CHECK_SLFRCS_ON_RESUME
def_bool n
help
On some boards it may be neccessary to hard reset early
during resume from S3 if the SLFRCS register indicates that
a memory channel is not guaranteed to be in self-refresh.
On other boards the check always creates a false positive,
effectively making it impossible to resume.
config SMM_RESERVED_SIZE
hex
default 0x100000
