Add predefined __ROMSTAGE__ and __RAMSTAGE__ macros
This patch adds the macros __ROMSTAGE__ and __RAMSTAGE__ which get
predefined in their respective stages by make, so that we have one
specific macro for every stage. It also renames __BOOT_BLOCK__ and
__VER_STAGE__ to __BOOTBLOCK__ and __VERSTAGE__ for consistency.
This change is intended to provide finer control and clearer
communication of intent after we added a new (optional) stage that falls
under __PRE_RAM__, and will hopefully provide some robustness for the
future (we don't want to end up always checking for romstage with #if
defined(__PRE_RAM__) && !defined(__BOOT_BLOCK__) &&
!defined(__VER_STAGE__) && !defined(__YET_ANOTHER_PRERAM_STAGE__)). The
__PRE_RAM__ macro stays as it is since many features do in fact need to
differentiate on whether RAM is available. (Some also depend on whether
RAM is available at the end of a stage, in which case #if
!defined(__PRE_RAM__) || defined(__ROMSTAGE__) should now be
authoritative.)
It's unfeasable to change all existing occurences of __PRE_RAM__ that
would be better described with __ROMSTAGE__, so this patch only
demonstratively changes a few obvious ones in core code.
BUG=None
TEST=None (tested together with dependent patch).
