[PATCH v3 3/4] x86: Avoid #ifdef with CONFIG_HAVE_ACPI_RESUME
Simon Glass
sjg at chromium.org
Fri Jul 10 02:43:16 CEST 2020
At present this enables a few arch-specific members of the global_data
struct which are otherwise not part of the struct. As a result we have to
use #ifdef in various places.
The cost of always having these in the struct is small. Adjust things so
that we can use compile-time code instead of #ifdefs.

(no changes since v2)
Changes in v2:
- Use new three-argument CONFIG_IS_ENABLED() instead
