Get predefined boot options for platform.
@param[out] Count The number of elements in each of
BootOptions and BootKeys. On successful
return, Count is at least one.
@param[out] BootOptions An array of platform boot options.
BootOptions is pool-allocated by
GET_PLATFORM_BOOT_OPTIONS_AND_KEYS, and
GET_PLATFORM_BOOT_OPTIONS_AND_KEYS populates
every element in BootOptions with
EfiBootManagerInitializeLoadOption().
BootOptions shall not contain duplicate
entries. The caller is responsible for
releasing BootOptions after use with
EfiBootManagerFreeLoadOptions().
@param[out] BootKeys A pool-allocated array of platform boot
hotkeys. For every 0 <= Index < Count, if
BootOptions[Index] is not to be associated
with a hotkey, then BootKeys[Index] is
zero-filled. Otherwise, BootKeys[Index]
specifies the boot hotkey for
BootOptions[Index]. BootKeys shall not
contain duplicate entries (other than
zero-filled entries). The caller is
responsible for releasing BootKeys with
FreePool() after use.
@retval EFI_SUCCESS Count, BootOptions and BootKeys have
been set.
@retval EFI_OUT_OF_RESOURCES Memory allocation failed.
@retval EFI_UNSUPPORTED The platform doesn't provide boot options
as a feature.
@retval EFI_NOT_FOUND The platform could provide boot options
as a feature, but none have been
configured.
@return Error codes propagated from underlying
functions.
