Hi Jifl
Thank you for your consideration.

May be confusing indeed. I developed the presented method in order to avoid
changes at architecture level. Now, provided that it is not a taboo - why not?
then for protection of legacy code we can use something like
#if defined(CYG_HAL_STARTUP_ROM) || defined(CYGINT_HAL_...)

/ROM/ does not imply /standalone/. FLASH startup from Bug #1001623 is being
started from RedBoot. And it shall implement both RAM and ROM interfaces.

Regarding remaining two options, I have no strong preference either, but
CYGINT_HAL_ROM_STARTUP seems slightly better distinguished from
CYG_HAL_STARTUP_ROM than the other one.
