Julius Werner 7fc928656e lib/fmap: Disable pre-RAM cache for FSP 1.0
Due to the way CAR teardown is handled in FSP 1.0, the results of
car_get_var_ptr() aren't always reliable, which can break things when
running with FMAP cache. It might be possible to fix this but would make
the code rather complicated, so let's just disable the feature on these
platforms and hope they die out soon.

Also allow this option to be used by platforms that don't have space for
the cache and want to save a little more code.

config MISSING_BOARD_RESET
bool
help
Selected by boards that don't provide a do_board_reset()
implementation. This activates a stub that logs the missing
board reset and halts execution.
config NO_EDID_FILL_FB
bool
default y if !MAINBOARD_DO_NATIVE_VGA_INIT
help
Don't include default fill_lb_framebuffer() implementation. Select
this if your drivers uses MAINBOARD_DO_NATIVE_VGA_INIT but provides
its own fill_lb_framebuffer() implementation.
config RAMSTAGE_ADA
bool
help
Selected by features that use Ada code in ramstage.
config RAMSTAGE_LIBHWBASE
bool
select RAMSTAGE_ADA
help
Selected by features that require `libhwbase` in ramstage.
config FLATTENED_DEVICE_TREE
bool
help
Selected by features that require to parse and manipulate a flattened
devicetree in ramstage.
config GENERIC_SPD_BIN
bool
help
If enabled, add support for adding spd.hex files in cbfs as spd.bin
and locating it runtime to load SPD. Additionally provide provision to
fetch SPD over SMBus.
config DIMM_MAX
int
default 4
help
Total number of memory DIMM slots available on motherboard.
It is multiplication of number of channel to number of DIMMs per
channel
config DIMM_SPD_SIZE
int
default 256
help
Total SPD size that will be used for DIMM.
Ex: DDR3 256, DDR4 512.

config NO_FMAP_CACHE
bool
help
If your platform really doesn't want to use an FMAP cache (e.g. due to
space constraints), you can select this to disable warnings and save
a bit more code.
