As we move to supporting other systems we need to get rid of assembly
where we can. The log2 function in src/lib is identical to the assembly
one (tested for all 32-bit signed integers :-) and takes about 10 ns
to run as opposed to 5ns for the non-portable assembly version. While speed
is good, I think we can spare the 15 ns or so we add to boot time
by using the C version only.

This gets rid of the somewhat unstructured placement of AMD's
sysinfo structure in CAR.
We used to carve out some CAR space using a Kconfig variable,
and then put sysinfo there manually (by "virtue" of pointer magic).
Now it's a variable with the CAR_GLOBAL qualifier, and build
system magic.
For this, the following steps were done (but must happen together
since the intermediates won't build):
- Add new CAR_GLOBAL sysinfo_car
- point all sysinfo pointers to sysinfo_car instead of GLOBAL_VAR
- remove DCACHE_RAM_GLOBAL_VAR_SIZE
- from CAR setup (no need to reserve the space)
- commented out code (that was commented out for years)
- only copy sizeof(sysinfo) into RAM after ram init, where
before it copied the whole GLOBAL_VAR area.
- from Kconfig

- Override on AMD Model fxx, 10xxx, agesa CPUs with 200MHz
- compile LAPIC code for romstage, too
- Remove #include ".../apic_timer.c" in AMD based mainboards
- Remove custom udelay implementation from intel northbridges' romstages
Future work:
- remove the compile time special case
(requires some cpuid based switching)
- drop northbridge udelay implementations (i945, i5000) if
not required anymore (eg. can SMM use the LAPIC timer?)

After collecting dependencies for ramstage, add an intermediate step
in which object files are linked per directory. The results are then
linked into the final binary.
This reduces the maximum command line length and might also help with
future use of LTO linking.
Also adapt the lint test for build dir handling, since printall
doesn't provide individual object files for ramstage anymore.

c_start.o has a special case in the build system, which we can
eliminate, somewhat simplifying the build.
To ensure that the entry point is at the beginning, introduce a
new section .textfirst that is placed appropriately. In principle
the ENTRY() definition in the linker script should be enough, but
better be safe.

The use of ramstage.a required the build system to handle some
object files in a special way, which were put in the drivers
class.
These object files didn't provide any symbols that were used
directly (but only via linker magic), and so the linker never
considered them for inclusion.
With ramstage.a gone, we can drop this special class, too.

ramstage.a has two issues:
1. duplicate source filenames don't survive the ar(1)
treatment properly (so files aren't considered)
2. ld doesn't resolve symbols if it isn't forced to, in
particular no overrides of weak symbols
Downside: The resulting binaries get slightly larger.
Link time optimizations should fix that, as would tighter
rules in the build system (to not compile unused code in
the first place).

This adds more configurability to POST codes. The current assumption
is that POST codes should be written to an IO port (e.g. LPC) if POST
codes are enabled. This changes the assumption so that POST codes can
be written to the serial console without being written to an IO port.
This enables POST codes by default using "default y" to avoid
changing current behavior.

We have to free TDs more carefully if they have been processed by the
controller yet. The current code tries to force the controller to post
them back to the done queue, but that seems wrong. We can't be sure,
when they get written back. This resulted in leaking TDs with an invalid
reference to a freed interrupt queue.
The new approach: Mark the interrupt queue to be destroyed and handle
the freeing later, when the controller posted the last TD to the done
queue.

The linking of interrupt queues into UHCI controller's framelist (in
uhci_create_intr_queue()) was incomplete. The implementation of
uhci_destroy_intr_queue() was even worse, looking like it wanted to
clean up more than uhci_create_intr_queue() did.
This patch follows the simple approach that we used for OHCI and EHCI:
Each slot in the framelist holds only one interrupt queue. Therefore, we
have to look for free slots each time we want to link an interrupt queue
into the framelist. In return, we have a much simpler structured
framelist.
With this, USB devices using interrupt transfers (e.g. keyboards) can be
detached cleanly from UHCI controllers. Also, more than one of such
devices can be attached without further risk.

Found a bug in the memory allocator ;-)
If the total free space in an alignment region is large enough for an
allocation but fragmented, such that there is no contiguous, sufficient
large, free space in the region, memalign() was looking at the same
region again and again in an endless loop. The advancing to the next
region was just missing.

We had mixed virtual and physical pointers in struct sysinfo_t. Some
being virtual by accident which led to problems when we tried to
reinitialize lib_sysinfo after relocating FILO (to get intentionally
virtual pointers valid again). I guess this didn't cause much trouble
before, as lib_get_sysinfo() was always called with physical addresses
being equal to their virtual counterparts.
For FILO, two possibilities seem practical: Either, have all pointers in
struct sysinfo_t physical, so relocation doesn't hurt. Or, have all
pointers virtual and call lib_get_sysinfo() again after relocation.
This patch goes the latter way, changing the following pointers for
situations where virtual pointers differ from physical:
.extra_version
.build
.compile_time
.compile_by
.compile_host
.compile_domain
.compiler
.linker
.assembler
.cb_version
.vdat_addr
.tstamp_table
.cbmem_cons
.mrc_cache
We could also just correct the accidentally virtual pointers. But, IMO,
this would lower the risk of future confusion.
Note 1: Looks like .version gets never set.
Note 2: .option_table and .framebuffer were virtual pointers but treated
like physical ones. Even in FILO, this led to no problems as
they were set before relocation.

uhci_reset() differs in semantics compared to the other HCI's reset()
implementations. uhci_reset() does some initialization work after a
controller reset. So move the initialization part to a new function,
uhci_reinit(), which get's exported through a new entry in hci_t:
hci_t.init().
Warning: This breaks code that relies on the current, special,
counterintuitive behaviour of uhci_reset(). If one wants a working host
controller after calling hci_t.reset(), he should call hci_t.init()
afterwards.

This is currently used by the ELOG GSMI interface but is a
good way to pass data to SMM so move the current searching code
to a separate function and make it a bit more versatile with the
checks it does to find a match so it can be used in other
situations.

The SMM GNVS pointer is normally updated only when the
ACPI tables are created, which does not happen in the
resume path.
In order to restore this pointer it needs to be available
at resume time. The method used to locate it at creation
time cannot be used again as that magic signature is
overwritten with the address itself. So a new CBMEM ID
is added to store the 32bit address so it can be found
again easily.
A new function is defined to save this pointer in CBMEM
which needs to be called when the ACPI tables are created
in each mainboard when write_acpi_tables() is called.
The cpu_index variable had to be renamed due to a conflict
when cpu/cpu.h is added for the smm_setup_structures()
prototype.

If the PEI System Agent doesn't run PCIe initialization, the PEG
clock gating will not be setup. Add the PEG clock gating when
pei_data->pcie_init is 0.

The IvyBridge reference code does some slow and
extensive PCIe init that we do not need on Link.
Hence, add a flag to disable/enable running that
init code from coreboot.
NMode was used during bringup. We'll switch
the setting back to auto, to let MRC decide the right thing.

This will enable DDR3 1.35V support for memory training in
the reference code. It requires the board to be setup for
1.35V with whatever board-specific GPIOs are available.

Let memory initialization code use the coreboot romstage console. This
simplifies the code and makes sure that all output is available in
/sys/firmware/log.
The pei_data structure is modified to allow passing the console output
function pointer. Romstage console_tx_byte() is used for this purpose.

This prepares the way for vboot to inform coreboot when it needs the VGA
Option ROM loaded. Coreboot can't always know when it's needed (with
keyboard-based dev-mode, coreboot can't tell if we're in dev-mode or not).
By the time we get to U-Boot, it's too late, so we need two extra bits - one
for vboot to tell coreboot to load the Option ROM and another for coreboot
to let vboot know it's been done.
This change sets up the communication, but doesn't act on it just yet.
Even with this CL we always load the VGA Option ROM, so there's nothing to
test. There should be no user-visible change.
