For emulation/qemu-q35 with ICH9 the choice INTERRUPT_ON_APIC_BUS was

For ICH4 and earlier, the choice to use FSB can be made based on the

This fixes a hard to debug hang that could occur in any stage, but in
the end it follows simple rules and is easy to fix.
In long mode the 32bit displacement addressing used on 'mov' and 'lea'
instructions is sign-extended. Those instructions can be found using
readelf on the stage and searching for relocation type R_X86_64_32S.
The sign extension is no issue when either running in protected mode or
the code module and thus the address is below 2GiB. If the address is
greater than 2GiB, as usually the case for code in TSEG, the higher
address bits [64:32] are all set to 1 and the effective address is
pointing to memory not paged. Accessing this memory will cause a page
fault, which isn't handled either.
To prevent such problems
- disable R_AMD64_32S relocations in rmodtool
- add comment explaining why it's not allowed
- use the pseudo op movabs, which doesn't use 32bit displacement addressing
- Print a useful error message if such a reloc is present in the code
Fixes a crash in TSEG and when in long mode seen on Intel Sandybridge.

The CBFS mcache size default was eyeballed to what should be "hopefully
enough" for most users, but some recent Chrome OS devices have already
hit the limit. Since most current (and probably all future) x86 chipsets
likely have the CAR space to spare, let's just double the size default
for all supporting chipsets right now so that we hopefully won't run
into these issues again any time soon.
The CBFS_MCACHE_RW_PERCENTAGE default for CHROMEOS was set to 25 under
the assumption that Chrome OS images have historically always had a lot
more files in their RO CBFS than the RW (because l10n assets were only
in RO). Unfortunately, this has recently changed with the introduction
of updateable assets. While hopefully not that many boards will need
these, the whole idea is that you won't know whether you need them yet
at the time the RO image is frozen, and mcache layout parameters cannot
be changed in an RW update. So better to use the normal 50/50 split on
Chrome OS devices going forward so we are prepared for the eventuality
of needing RW assets again.
The RW percentage should really also be menuconfig-controllable, because
this is something the user may want to change on the fly depending on
their payload requirements. Move the option to the vboot Kconfigs
because it also kinda belongs there anyway and this makes it fit in
better in menuconfig. (I haven't made the mcache size
menuconfig-controllable because if anyone needs to increase this, they
can just override the default in the chipset Kconfig for everyone using
that chipset, under the assumption that all boards of that chipset have
the same amount of available CAR space and there's no reason not to use
up the available space. This seems more in line with how this would work
on non-x86 platforms that define this directly in their memlayout.ld.)
Also add explicit warnings to both options that they mustn't be changed
in an RW update to an older RO image.

This patch removes the prog_locate() step for stages and rmodules.
Instead, the stage and rmodule loading functions will now perform the
locate step directly together with the actual loading. The long-term
goal of this is to eliminate prog_locate() (and the rdev member in
struct prog that it fills) completely in order to make CBFS verification
code safer and its security guarantees easier to follow. prog_locate()
is the main remaining use case where a raw rdev of CBFS file data
"leaks" out of cbfs.c into other code, and that other code needs to
manually make sure that the contents of the rdev get verified during
loading. By eliminating this step and moving all code that directly
deals with file data into cbfs.c, we can concentrate the code that needs
to worry about file data hashing (and needs access to cbfs_private.h
APIs) into one file, making it easier to keep track of and reason about.
This patch is the first step of this move, later patches will do the
same for SELFs and other program types.
