Macros can be confusing on their own; hiding commas make things worse.
This can sometimes be downright misleading. A "good" example would be
the code in soc/intel/xeon_sp/spr/chip.c:
CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev,
This appears as CHIP_NAME() being some struct when in fact these are
defining 2 separate members of the same struct.
It was decided to remove this macro altogether, as it does not do
anything special and incurs a maintenance burden.

Having a separate romstage is only desirable:
- with advanced setups like vboot or normal/fallback
- boot medium is slow at startup (some ARM SOCs)
- bootblock is limited in size (Intel APL 32K)
When this is not the case there is no need for the extra complexity
that romstage brings. Including the romstage sources inside the
bootblock substantially reduces the total code footprint. Often the
resulting code is 10-20k smaller.
This is controlled via a Kconfig option.
TESTED: works on qemu x86, arm and aarch64 with and without VBOOT.

instead. The Glinda code is right now just a copy of the Mendocino code,
so it'll change in the future, but for consistency the equivalent
changes to those in Mendocino are applied there too.
