CBMEM console buffer size is adjustable in menuconfig, but this would
not correctly adjust the overall allocation made for CBMEM.
HIGH_MEMORY_SIZE is aligned to 64kB and definitions are moved down in
the header file as HIGH_MEMORY_SIZE is not used with DYNAMIC_CBMEM.
Try to continue boot even if CBMEM cannot be created. This error would
only occur during development of new ports anyways and more log output
is better.

This patch implements the basic infrastructure required to use the USB
A-A firmware upload feature on Exynos5 processors with Coreboot. It will
require a corresponding host-side script that activates the feature and
uploads the correct image parts in the correct order to harcoded target
addresses, as described in the comments of alternate_cbfs.c.
Also fixes a bug in the Google Snow mainboard where it would not
correctly initialize the pinmux configuration for the SPI flash bus.
During a normal SPI boot the IROM would already do that for you, but
when booting from USB you have to do it yourself.

walkcbfs() is used only with ROMCC. Besides finding stages during the
bootblock, it's also used when applying microcode updates during the
bootblock phase. The function used to return only a pointer to the data of
the CBFS file, while making the header completely inaccessible. Since the
header contains the length of the CBFS file, the caller did not have a way
to know how long the data was. Then, other conventions had to be used to
determine the EOF, which might present problems if the user replaces the
CBFS file. This is not an issue when jumping to a stage (romstage), but can
present problems when accessing a microcode file which has not been
NULL-terminated.
Refactor walkcbfs_asm to return a pointer to the CBFS file header rather
than the data. Rename walkcbfs() to walkcbfs_head(), and reimplement a new
walkcbfs() based on walkcbfs_head(). Thus current usage of walkcbfs()
remains unaffected.
The code has been verified to run successfully under qemu.
Subsequent patches will change usage of walkcbfs() to walkcbfs_head where
knowing the length of the data is needed.

The original intention was to only run UPDATE_FIT when a microcode file was
included in CBFS. This happens when either CPU_MICROCODE_CBFS_GENERATE or
CPU_MICROCODE_CBFS_EXTERNAL is selected, however, the makefile checked that
CPU_MICROCODE_IN_CBFS was selected instead. The end result was that on
hasswell, the UPDATE-FIT step was always run, even when no microcode was
included, generating a build error.
Instead, introduce a new variable which tells if a microcode update is
added in CBFS during the build.

One of the most common hangs during coreboot execution
is during ramstage device init steps. Currently there
are a set of (somewhat misleading) post codes during this
phase which give some indication as to where execution
stopped, but it provides no information on what device
was actually being initialized at that point.
This uses the new CMOS "extra" log banks to store the
encoded device path of the device that is about to be
touched by coreboot. This way if the system hangs when
talking to the device there will be some indication where
to investigate next.

Since a long time GRUB 2 is a viable payload alternative to SeaBIOS and
FILO. So make it easy for coreboot users to use GRUB 2 as a payload by
integrating it into coreboot’s build system, so it can be selected in
Kconfig.
As the last GRUB 2 release 2.00 is too old and has several bugs when
used as a coreboot payload only allow to build GRUB 2 master until a new
GRUB release is done. The downside is, that accidental breakage in
GRUB’s upstream does not affect coreboot users.
Currently the GRUB 2 payload is built with the default modules which
results in an uncompressed size of around 730 kB. Compressed it has a
size of 340 kB, so it should be useable with 512 kB flash ROMs.

For both romstage and ramstage, this calls an arch-specific function
get_cbmem_table() to resolve the base and size of CBMEM region. In ramstage,
the result is cached as the query may be relatively slow involving multiple PCI
configuration reads.
For x86 CBMEM tables are located right below top of low ram and
have fixed size of HIGH_MEMORY_SIZE in EARLY_CBMEM_INIT implementation.

At least when building with the gnu toolchain, the headers the linker
automatically generate save space for the actual ELF headers in one of the
loadable segments. This creates two problems. First, the data you intended to
be at the start of the image doesn't actually show up there, it's actually the
ELF headers. Second, the ELF headers are essentially useless for firmware
since there's currently nothing to tell you where they are, and even if there
was, there isn't much of a reason to look at them. They're useful in userspace
for, for instance, the dynamic linker, but not really in firmware.
This change adds a PHDRS construct to each of the linker scripts used on ARM
which define a single segment called to_load which does not have the flag set
which would tell the linker to put headers in it. The first section defined in
the script has ": to_load" to tell the linker which segment to put it in, and
from that point on the other sections go in there by default.

The memset and memcpy functions are assembled as ARM code, likely because
that's the default of the assembler. Without special annotation, the assembler
and linker don't know that those symbols are functions which need special
handling so that ARM/thumb issues are handled properly. This change adds that
annotation which gets those functions working in Coreboot which is compiled as
thumb. Libpayload and depthcharge are compiled as ARM so they don't *need* the
annotation since it just works out in ARM mode, but it's the safe thing to do
in case we change that in the future.
We should explicitly select ARM vs. thumb when assembling assembly files to be
consistent across builds and toolchains.

When modifying the page tables, use writel to ensure the writes happen, flush
the page tables themselves to ensure they're visible to the MMU if it doesn't
look at the caches, and invalidate the right TLB entries.
The first two changes are probably safer but may not be strictly necessary.
The third change is necessary because we were invalidating the TLB using i
which was in megabytes but using an instruction that expects an address in
bytes.
One symptom of this problem was that the framebuffer, which was supposed to be
marked uncacheable, was only being partially updated since some of the updates
were still in the cache. With this change the graphics show up correctly.

The page tables need to be aligned to a 16KB boundary and are 16KB in size.
The CBMEM allocator only guarantees 512 byte alignment, so to make sure
things are where they're supposed to be, the code was allocating extra space
and then adjusting the pointer upwards. Unfortunately, it was adding the size
of the table to the pointer first, then aligning it. Since it allocated twice
the space of the table, this had the effect of moving past the first table
size region of bytes, and then aligning upwards, pushing the end of the table
out of the space allocated for it.
You can get away with this if you push things you don't care about off the
end, and it happened to be the case that we were allocating a color map we
weren't using at the start of the next part of cbmem.

- Guard console_init() with CONFIG_EARLY_CONSOLE in bootblock
- Don't initialize console twice in the bootblock
- remove printk in memory init that would mess up the UART
- unconditionally run console_init() in romstage, as it is
also unconditionally run in the bootblock.

When starting the Exynos5250 port, a lot of unneeded u-boot code
was imported. This is an attempt to get rid of a lot of unneeded
code before the port is used as a basis for further ARM ports.
There is a lot more that can be done, including cleaning up the
5250's Kconfig file.

This patch unfortunately incorporates a number of changes,
all of which are making future ARM ports easier.
- drop cruft that came in with u-boot
- move serial console from mainboard Kconfig to Exynos Kconfig
- factor out non-board specific wakeup code
- move generic bootblock code from mainboard to Exynos
- actually call arch_cpu_init()
- remove dead code
- fix up copyright messages
- remove snow_ prefix from a lot of code to reduce the noise
when creating a new mainboard based on that code.

Define at one place whether to use IO 0xcf8/0xcfc or MMIO via
MMCONF_BASE_ADDRESS for PCI configuration access funtions in ramstage.
The implementation of pci_default_config() always returned with
pci_cf8_conf1. This means any PCI configuration access that did
not target bus 0 used PCI IO config operations, if PCI MMIO config
was not explicitly requested.

On ARM, there's frequently some firmware built into the SOC which runs
first and which loads other firmware like Coreboot from some other
media. To prevent the bootblock from having to know how to find and load
the ROM stage from what may be a complicated source (sd card,
netbooting, etc.), we can put the ROM stage immediately after the
bootblock and ensure that they're both loaded at the same time.
This change adjusts the Makefile.inc for ARM so that the ROM stage is put
into the image before any other files so that we know it comes first.
This changes the behavior of the CONFIG_UPDATE_IMAGE config option used
by abuild, although it's not entirely clear whether that's still used.

This patch adds a qemu x86 cpu chip. It has no initialization function
as this isn't needed on virtual hardware. A virtual machine can have
pretty much any CPU: qemu emulates a wide range of x86 CPUs (try 'qemu
-cpu ? for a list), also with 'qemu -cpu host' the guest will see a cpu
which is (almost) identical to the one on the host machine. So I've
added X86_VENDOR_ANY as wildcard match for the cpu_table.

The MARK_GRAPHICS_MEM_WRCOMB was spreading like a cancer
since it was defined in sandybridge. It is really
more of an x86 thing however, and we now have
three systems that can use it.
I considered making this more general, since it technically
can apply to PTE-based systems like ARM, and maybe we should.
But the 'WRCOMB' moniker is usually closely tied to the x86.

There are some boards that do a significant amount of
work after cache-as-ram is torn down but before ramstage
is loaded. For example, using vboot to verify the ramstage
is one such operation. However, there are pieces of code
that are executed that reference global variables that
are linked in the cache-as-ram region. If those variables
are referenced after cache-as-ram is torn down then the
values observed will most likely be incorrect.
Therefore provide a Kconfig option to select cache-as-ram
migration to memory using cbmem. This option is named
CAR_MIGRATION. When enabled, the address of cache-as-ram
variables may be obtained dynamically. Additionally,
when cache-as-ram migration occurs the cache-as-ram
data region for global variables is copied into cbmem.
There are also automatic callbacks for other modules
to perform their own migration, if necessary.

The cooperative multitasking support allows the boot state machine
to be ran cooperatively with other threads of work. The main thread
still continues to run the boot state machine
(src/lib/hardwaremain.c). All callbacks from the state machine are
still ran synchronously from within the main thread's context.
Without any other code added the only change to the boot sequence
when cooperative multitasking is enabled is the queueing of an idlle
thread. The idle thread is responsible for ensuring progress is made
by calling timer callbacks.
The main thread can yield to any other threads in the system. That
means that anyone that spins up a thread must ensure no shared
resources are used from 2 or more execution contexts. The support
is originally intentioned to allow for long work itesm with busy
loops to occur in parallel during a boot.
Note that the intention on when to yield a thread will be on
calls to udelay().

I/O APIC registers.
printk(BIOS_SPEW, "Dumping IOAPIC registers\n");
for (i=0; i<3; i++) {
*ioapic_index = i;
printk(BIOS_SPEW, " reg 0x%04x:", i);
reg32 = *ioapic_data;
printk(BIOS_SPEW, " 0x%08x\n", reg32);
}
Add similar code to `src/arch/x86/lib/ioapic.c` so all boards using
the function `set_ioapic_id()` get the debug feature and the other
boards can be more easily adapted in follow-up patches.
