Previously Haswell used a romcc bootblock and starting verstage in
romstage was madatory but with C_ENVIRONMENT_BOOTBLOCK it is also
possible to have a separate verstage.
This selects using a separate verstage by default but still keeps the
option around to use verstage in romstage.
Also make sure mrc.bin is only added to the COREBOOT fmap region as it
requires to be run at a specific offset. This means that coreboot will
have to jump from a RW region to the RO region for that binary and
back to that RW region after that binary is done initializing the
memory.

This puts the cache-as-ram init in the bootblock.
Before setting up cache as ram the microcode updates are applied.
This removes the possibility for a normal/fallback setup although
implementing this should be quite easy.
Tested on Google peppy (Acer C720).
Setting up LPC in the bootblock to output console on SuperIOs is not
done in this patch, hence BOOTBLOCK_CONSOLE is not yet enabled by
default.

When the Haswell-specific monotonic timer is used on an ASRock H81M-HDS
with a Pentium G3258, the following exception is generated, causing the
system to hang.
CPU Index 0 - APIC 0 Unexpected Exception:13 @ 10:7f7a3736 - Halting
Code: 0 eflags: 00010006 cr2: 00000000
eax: 00262626 ebx: 00140000 ecx: 00000603 edx: 00360000
edi: 00000007 esi: 00262626 ebp: 7f7c0fd8 esp: 7f7c0e90
The exception occurs when trying to read `MSR_COUNTER_24_MHz`, located
at 0x637. This MSR only exists on Haswell-ULT CPUs.
So, allow boards to use the TSC monotonic timer instead. They can do
this by placing `select TSC_MONOTONIC_TIMER` in the mainboard Kconfig.

When CONFIG_CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM is set, this
function is now linked into the ramstage as well as the romstage,
since the former makes calls to it in panther builds.
With this commit, it's possible to build panther using the config file
from the Chromium OS project[1] if you supply the appropriate Intel
descriptor and ME binary blobs and manually set
CONFIG_VBOOT_VERIFY_FIRMWARE=n, CONFIG_BUILD_WITH_FAKE_IFD=n, and
CONFIG_HAVE_ME_BIN=y. The resulting image is at least able to load a
payload, although I only tested with depthcharge, which immediately
complained, "vboot handoff pointer is NULL" and gave up the ghost.

In some previous attempt to enable monotonic timers on all platforms,
the LAPIC monotonic timer was selected for Haswell devices, despite
the fact that LAPIC timers are not used in coreboot on Haswell
(See haswell Kconfig) and there already was a monotonic timer
implementation enabled that just needed to be added for SMM as well.

Start using the rmodtool for generating rmodules.
rmodule_link() has been changed to create 2 rules:
one for the passed in <name>, the other for creating
<name>.rmod which is an ELF file in the format of
an rmodule.
Since the header is not compiled and linked together
with an rmodule there needs to be a way of marking
which symbol is the entry point. __rmodule_entry is
the symbol used for knowing the entry point. There
was a little churn in SMM modules to ensure an
rmodule entry point symbol takes a single argument.

This patch parallelizes the AP startup for Haswell-based devices. It
does not touch the generic secondary startup code. Instead it provides
its own MP support matching up with the Haswell BWG. It seemed to be too
much trouble to support the old startup way and this new way. Because of
that parallel loading is the only thing supported.
A couple of things to note:
1. Micrcode needs to be loaded twice. Once before MTRR and caching is
enabled. And a second time after SMM relocation.
2. The sipi_vector is entirely self-contained. Once it is loaded and
written back to RAM the APs do not access memory outside of the
sipi_vector load location until a sync up in ramstage.
3. SMM relocation is kicked off by an IPI to self w/ SMI set as the
destination mode.
The following are timings from cbmem with dev mode disabled and recovery mode
enabled to boot directly into the kernel. This was done on the
baskingridge CRB with a 4-core 8-thread CPU and 2 DIMMs 1GiB each. The
kernel has console enabled on the serial port. Entry 70 is the device
initialization, and that is where the APs are brought up. With these two
examples it looks to shave off ~200 ms of boot time.

It was found that the Haswell reference code was smashing through the
stack into the reference code's heap implementation. The reason for this
is because our current CAR allocation is too small. Moreover there are
quite a few things to coordinate between 2 code bases to get correct.
This commit separates the CAR into 2 parts:
1. MRC CAR usage.
2. Coreboot CAR usage.
Pointers from one region can be passed between the 2 modules, but one
should not be able to affect the others as checking has been put into
place in both modules.
The CAR size has effectively been doubled from 0x20000 (128 KiB) to
0x40000 (256KiB). Not all of that increase was needed, but enforcing
a power of 2 size only utilizes 1 MTRR.
Old CAR layout with a single contiguous stack with the region starting
at CONFIG_DCACHE_RAM_BASE:
+---------------------------------------+ Offset CONFIG_DCACHE_RAM_SIZE
| MRC global variables |
| CONFIG_DCACHE_RAM_MRC_VAR_SIZE bytes |
+---------------------------------------+
| ROM stage stack |
| |
| |
+---------------------------------------+
| MRC Heap 30000 bytes |
+---------------------------------------+
| ROM stage console |
| CONFIG_CONSOLE_CAR_BUFFER_SIZE bytes |
+---------------------------------------+
| ROM stage CAR_GLOBAL variables |
+---------------------------------------+ Offset 0
There was some hard coded offsets in the reference code wrapper to start
the heap past the console buffer. Even with this commit the console
can smash into the following region depending on what size
CONFIG_CONSOLE_CAR_BUFFER_SIZE is.
As noted above This change splits the CAR region into 2 parts starting
at CONFIG_DCACHE_RAM_BASE:
+---------------------------------------+
| MRC Region |
| CONFIG_DCACHE_RAM_MRC_VAR_SIZE bytes |
+---------------------------------------+ Offset CONFIG_DCACHE_RAM_SIZE
| ROM stage stack |
| |
| |
+---------------------------------------+
| ROM stage console |
| CONFIG_CONSOLE_CAR_BUFFER_SIZE bytes |
+---------------------------------------+
| ROM stage CAR_GLOBAL variables |
+---------------------------------------+ Offset 0
Another variable was add, CONFIG_DCACHE_RAM_ROMSTAGE_STACK_SIZE,
which represents the expected stack usage for the romstage. A marker
is checked at the base of the stack to determine if either the stack
was smashed or the console encroached on the stack.

The Haswell parts use a PCH code named Lynx Point (Series 8). Therefore,
the southbridge support is included as well. The basis for this code is
the Sandybridge code. Management Engine, IRQ routing, and ACPI still requires
more attention, but this is a good starting point.
This code partially gets up through the romstage just before training
memory on a Haswell reference board.
