This is needed only for platforms that enable EFI_LOADER.

I will check this, and keep it if any build/size impact happens. -sughosh > > Thanks > /Ilias > > Signed-off-by: Sughosh Ganu <[email protected]> > > --- > > Changes since V1: > > * Add a config for SPL stage > > > > lib/Kconfig | 17 +++++++++++++++++ > > 1 file changed, 17 insertions(+) > > > > diff --git a/lib/Kconfig b/lib/Kconfig > > index 1dd4f271595..61452f7ac94 100644 > > --- a/lib/Kconfig > > +++ b/lib/Kconfig > > @@ -75,6 +75,23 @@ config LIB_UUID > > bool > > select SHA1 > > > > +config MEM_MAP_UPDATE_NOTIFY > > + bool "Get notified of any changes to the LMB memory map" > > + default y if EFI_LOADER > > + help > > + Enable this option to get notification on any changes to the > > + memory that is allocated or freed by the LMB module.
