Aaron Durbin 4409a5eef6 coreboot: add thread cooperative multitasking
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().

    […]

memory has to be reserved for the `PCIe_COMPLEX_DESCRIPTOR` and,
as two struct members are pointers to arrays with elements of type
`PCIe_PORT_DESCRIPTOR` and `PCIe_DDI_DESCRIPTOR`, space for these
times the number of array elements have to be reserved:
a + b * 5 + c * 2.

      sizeof(PCIe_COMPLEX_DESCRIPTOR)
    + sizeof(PCIe_PORT_DESCRIPTOR) * 5
    + sizeof(PCIe_DDI_DESCRIPTOR) * 2;

But for whatever reason parentheses were put in there making this
calculation incorrect and reserving too much memory.

    (a + b * 5 + c) * 2

So, remove the parentheses to reserve the exact amount of memory
needed.

The ASRock E350M1 still boots with these changes. No changes were
observed as expected.

Rudolf Marek made this change as part of his patch »ASUS F2A85-M:
Correct and clean up PCIe config« [1]. Factor this hunk out as it
affects all AMD Brazos and Trinity based boards.

Ronald G. Minnich 711a6fde0d Get rid of MAXIMUM_CONSOLE_LOGLEVEL; compile all messages into the coreboot binary
This option has never had much if any use. It solved a problem over 10
years ago that resulted from an argument over the value or lack thereof
of including all the debug strings in a coreboot image. The answer is
in: it's a good idea to maintain the capability to print all messages,
for many reasons.

This option is  also misleading people, as in a recent discussion, to
believe that log messges are controlled at build time in a way they are
not. For the record, from this day forward, we can print messages at all
log levels and the default log level is set at boot time, as directed by
DEFAULT_CONSOLE_LOGLEVEL. You can set the default to 0 at build time and
if you are having trouble override it in CMOS and get more messages.

Besides, a quick glance shows it's always set to max (9 in this case) in
the very few cases (1) in which it is set.

Aaron Durbin 703aa978aa x86: harden tsc udelay() function
Since the TSC udelay() function can be used in SMM that means the
TSC can count up to whatever value. The current loop was not handling
TSC rollover properly. In most cases this should not matter as the TSC
typically starts ticking at value 0, and it would take a very long time
to roll it over. However, it is my understanding that this behavior is
not guaranteed. Theoretically the TSC could start or be be written to
with a large value that would cause the rollover.

Aaron Durbin 0748d30554 boot state: add ability to block state transitions
In order to properly sequence the boot state machine it's
important that outside code can block the transition from
one state to the next. When timers are not involved there's
no reason for any of the existing code to block a state
transition. However, if there is a timer callback that needs to
complete by a certain point in the boot sequence it is necessary
to place a block for the given state.

To that end, 4 new functions are added to provide the API for
blocking a state.
1. boot_state_block(boot_state_t state, boot_state_sequence_t seq);
2. boot_state_unblock(boot_state_t state, boot_state_sequence_t seq);
3. boot_state_current_block(void);
4. boot_state_current_unblock(void);

Some boards use the local apic for udelay(), but they also provide
their own implementation of udelay() for SMM. The reason for using
the local apic for udelay() in ramstage is to not have to pay the
penalty of calibrating the TSC frequency. Therefore provide a
TSC_CONSTANT_RATE option to indicate that TSC calibration is not
needed. Instead rely on the presence of a tsc_freq_mhz() function
provided by the cpu/board.  Additionally, assume that if
TSC_CONSTANT_RATE is selected the udelay() function in SMM will
be the tsc.

David Hendricks 2fde9668b4 exynos5250/snow: deprecate time.h
time.h We Hardly Knew Ye.

This deprecates time.h which is currently only used by Exynos5250 and
Snow. The original idea was to try and unify some of the various timer
interfaces and has been supplanted by the monotonic timer API.

timer_us() is now obsolete. timer_start() is now mct_start() and
is exposed in exynos5250/clk.h.

Idwer Vollering 37714f33a6 crossgcc: update to gcc 4.7.3
Update crossgcc to use gcc 4.7.3
The resulting coreboot.rom is not runtime tested (any volunteers?).

Drop the texinfo patch, rename the armv7a patch.

Some Linux distributions have moved on to gcc 4.8,
under certain circumstances this version can't (cross-)compile gcc 4.7.2

`select UDELAY_LAPIC` is present in `src/cpu/amd/agesa/Kconfig` which
applies also to AMD Family 15tn.

Therefore remove `select UDELAY_LAPIC` again from
`cpu/amd/agesa/family15tn/Kconfig`.

`2 << 24`, which is the same value, makes it clear, that the
I/O APIC ID is 2.
