add_ivrs_device_entries() is a recursive function, and each recursive
call is passed a pointer to a root_level variable declared outside the
function. In an attempt to make the function self-contained, the initial
call is made with the root_level pointer set to NULL, and then the
function attempts to detect this and allocate a root_level variable for
the rest of the calls. This makes memory management very tricky - for
example, the pi code incorrectly attempts to free the root_level
variable at the end of *each* recursive call, which only avoids being a
double-free because free() in coreboot is currently a no-op. Let's
keep life simple and declare root_level as a local variable outside the
first function call instead.

This bit shift attempts to set bits 8 and 9 of the byte variable (counting
from 0). However, as the name suggests, this variable is only 8 bits
wide, so the shift does nothing. Reading section 7.5 of the
AMD SB800-Series Southbridges Register Programming Requirements manual,
bits 8 and 9 are already set by default, so we can remove the bit shift.
(Alternatively, we could try setting the corresponding bits one byte
higher in 0xF1 if needed.)

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.

The code currently checks that 4 <= dev_index <= 10, which after
subtraction by 4 can index into an array of length at most 7. This is
fine for the largest cpl array (which does have length 7), but is
too large for some of the others, which are smaller. This adds bounds
checks for each array access to ensure they are all within bounds.

There are two hard things in computer science: cache invalidation,
naming things, and off-by-one errors. -- Anonymous
var_num records the number of initialized entries in the reg_var array.
However, this means the index of the last initialized element is one
less than the value of var_num, so we need to take that into account
when indexing into the array. This has already been fixed in several
other places (eg. sb/amd/pi/hudson/lpc.c), so let's also do so here.
