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.

This can be used to indicate sub-state within a POST
code range which can assist in debugging BIOS hangs.
For example this can be used to indicate which device
is about to be initialized so if the system hangs
while talking to that device it can be identified.

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.
Tested with QEMU.

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.

Split PCI IO configuration and MMIO configuration cycles to separate

after initial setup in bootblock.
Note that the pci_mmio_ and pcie_ functions were different in masking
the alignment for register address. PCI standard requires that 16-bit
and 32-bit configuration register writes do not cross boundaries.

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.

It might be that you want an early console in romstage before RAM is up, but
you can't or don't want to support the console all the way back in the
bootblock. By making the console in those two different environments
configurable seperately that becomes possible.
On the 5250 console output as early as the bootblock works, but on the 5420 it
only starts working in the ROM stage after clocks have been initialized.

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.

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.

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().

Some southbridges have code in their `lpc.c` files to dump the
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.

The old approach was to invalidate the entire TLB every time we set up
a table entry. This worked because we didn't turn the MMU on until
after we had set everything up. This patch uses the TLBIMVAA wrapper
to invalidate each entry as it's added/modified.

It is useful to be able to lock out certain address ranges,
NULL being the most important example.
void mmu_disable_range(unsigned long start_mb, unsigned long size_mb)
will allow us to lock out selected virtual addresses on MiB boundaries.
As in other ARM mmu functions, the addresses and quantities are in units

On x86 systems there is a concept of cachings the ROM. However,
the typical policy is that the boot cpu is the only one with
it enabled. In order to ensure the MTRRs are the same across cores
the rom cache needs to be disabled prior to OS resume or boot handoff.
Therefore, utilize the boot state callbacks to schedule the disabling
of the ROM cache at the ramstage exit points.

Utilize the static boot state callback scheduling to initialize
and tear down the coverage infrastructure at the appropriate points.
The coverage initialization is performed at BS_PRE_DEVICE which is the
earliest point a callback can be called. The tear down occurs at the
2 exit points of ramstage: OS resume and payload boot.

It's helpful to provide a distinct state that affirmatively
describes that OS resume will occur. The previous code included
the check and the actual resuming in one function. Because of this
grouping one had to annotate the innards of the ACPI resume
path to perform specific actions before OS resume. By providing
a distinct state in the boot state machine the necessary actions
can be scheduled accordingly without modifying the ACPI code.

Many of the boot state callbacks can be scheduled at compile time.
Therefore, provide a way for a compilation unit to inform the
boot state machine when its callbacks should be called. Each C
module can export the callbacks and their scheduling requirements
without changing the shared boot flow code.

This gets rid of the clock-tick based sdelay in favor of udelay().
udelay() is more consistent and easier to work with, and this allows
us to carry one less variation of timers (and headers and sources...).
Every 1 unit in the sdelay() argument was assumed to cause a delay of
2 clock ticks (@1.7GHz). So the conversion factor is roughly:
sdelay(N) = udelay(((N * 2) / 1.7 * 10^9) * 10^6)
= udelay((N * 2) / (1.7 * 10^3))
The sdelay() periods used were:
sdelay(100) --> udelay(1)
sdelay(0x10000) --> udelay(78) (rounded up to udelay(100))
There was one instance of sdelay(10000), which looked like sort of a
typo since sdelay(0x10000) was used elsewhere. sdelay(10000) should
approximate to about 12us, so we'll stick with that for now and leave
a note.

Add a microsecond timer, its declaration, the function to start it,
and its usage. To start it, one calls timer_start(). From that point
on, one can call timer_us() to find microseconds since the timer was
started.
We show its use in the bootblock. You want it started very early.
Finally, the delay.h change having been (ironically) delayed, we
create time.h and have it hold one declaration, for the timer_us() and
timer_start() prototype.
We feel that these two functions should become the hardware specific
functions, allowing us to finally move udelay() into src/lib where it
belongs.

This enables type checking for safety as to help prevent errors like
http://review.coreboot.org/#/c/3038/ . Now compilation fails if the
wrong type is passed into readb/readw/readl/writeb/writew/writel
or other macros in io.h.
This also deprecates readw/writew. The previous definition was 16-bits
which is incorrect since wordsize on ARMv7 is 32-bits and there was
only 1 instance of writew (#if 0'd anyway). Going forward we should
always use read{8,16,32} and write{8,16,32} where N specifies the
exact length rather than relying on ambiguous definition of wordsize.
Since many macros relied on __raw_*, which were basically the same
(minus data memory barrier instructions), this patch also gets rid
of __raw_*. There were parts of the code which ended up using these
macros consecutively, for example:
setbits_le32(®s->ch_cfg, SPI_CH_RST);
clrbits_le32(®s->ch_cfg, SPI_CH_RST);
In such cases the safe versions of readl() and writel() should be
used anyway.
Note: This also fixes two dubious casts as to avoid breaking
compilation.

This adds condition codes when using the msr instruction. Although
described as "optional" in the Cortex-A series programmer's guide,
our experience with using the msr instruction in the payload suggests
that the condition code is not optional and that this only worked
in coreboot (and u-boot) because the processor comes up in SVC32 mode.

The ACPI NVS region was setup in place and there was a CBMEM
table that pointed to it. In order to be able to use NVS
earlier the CBMEM region is allocated for NVS itself during
the LPC device init and the ACPI tables point to it in CBMEM.
The current cbmem region is renamed to ACPI_GNVS_PTR to
indicate that it is really a pointer to the GNVS and does
not actually contain the GNVS.

On certain architectures such as x86 the bootstrap processor
does most of the work. When CACHE_ROM is employed it's appropriate
to ensure that the caching enablement of the ROM is disabled so that
the caching settings are symmetric before booting the payload or OS.
Tested this on an x86 machine that turned on ROM caching. Linux did not
complain about asymmetric MTRR settings nor did the ROM show up as
cached in the MTRR settings.
