The set of subdirs needed in $(obj-y) is specified at the top of the file.
Also shouldn't this be obj-$(CONFIG_DOMAIN_BUILDER)?
Later, all boot-time domain building is handled by
domain-builder/core.c. So some of domain-builder/ is always built, and
Kconfig disables multidomain support.
Then CONFIG_DOMAIN_BUILDER is a misnomer?
Dan also adds CONFIG_MULTIDOMAIN_BUILDER later... which is used only for:
- BUG_ON(!pv_shim && d->domain_id != 0);
+ if ( ! IS_ENABLED(CONFIG_MULTIDOMAIN_BUILDER) )
+ BUG_ON(!pv_shim && d->domain_id != 0);
:(
I thought it at least restricted the size of the boot domains array.
