Implicit fall throughs are a perpetual source of bugs and Coverity Scan
issues, so let's squash them once and for all. GCC can flag implicit fall
throughs using the -Wimplicit-fallthrough warning, and this should
ensure no more enter the code base. However, many fall throughs are
intentional, and we can use the following comment style to have GCC
suppress the warning.
switch (x) {
case 1:
y += 1;
/* fall through */
case 2:
y += 2;
/* fall through - but this time with an explanation */
default:
y += 3;
}
This patch adds comments for all remaining intentional fall throughs,
and tweaks some existing fall through comments to fit the syntax that
GCC expects.

"if (_pcidata != 0xFFFFFFFF || _pcidata != 0)", is always true.
The right test should be && not ||.
Error found using -Wlogical-op warning option.

This patch fixes up all code that would throw a -Wtype-limits warning.
This sometimes involves eliminating unnecessary checks, adding a few odd
but harmless casts or just pragma'ing out the warning for a whole file
-- I tried to find the path of least resistance. I think the overall
benefit of the warning outweighs the occasional weirdness.

Fix regression of IDS debugging after commit
1210026 AGESA buildsystem: Reduce include path exposure
Mainboard directory was removed from libagesa includes
path here, and this resulted with fam15tn and fam16kb using
a template OptionsIds.h file under vendorcode/ instead.
Add mainboard directory back to include path of libagesa
and remove those (empty) template files.

Having CFLAGS with -Os disables -falign-function, for
unlucky builds this may delay entry to ramstage by 600ms.
Build the low-level IO functions aligned with -O2 instead.
