Nico Huber 393619b9a6 intel/gm45: Add more debug output to read/write training
Add debug output for the timing values of the edges found during
read and write training.

Now, output for one DIMM of DDR3-1066 in a roda/rk9 looks like:

[...]
Lower bound for byte lane 0 on channel 0: 0.0
Upper bound for byte lane 0 on channel 0: 8.4
Final timings for byte lane 0 on channel 0: 4.2
Lower bound for byte lane 1 on channel 0: 0.0
Upper bound for byte lane 1 on channel 0: 10.2
Final timings for byte lane 1 on channel 0: 5.1
Lower bound for byte lane 2 on channel 0: 0.0
Upper bound for byte lane 2 on channel 0: 7.5

Upper bound for group 2 on channel 0: 2.8.1
Final timings for group 2 on channel 0: 2.4.4
Lower bound for group 3 on channel 0: 2.4.7
Upper bound for group 3 on channel 0: 3.0.0
Final timings for group 3 on channel 0: 2.8.3
[...]

Final timings are always the average of the two bounds. The last dots
separate eights (not decimals) and the middles are elenvenths or twelfths
depending on the clock speed (twelfths in this case).

Paul Menzel b2cddd4c12 ASUS F2A85-M: romstage.c: Set RAM voltage for non 1.5 Volt case
Currently the code in the if statement

    if (!byte)
    	do_smbus_write_byte(0xb20, 0x15, 0x3, byte);

only gets executed if `byte == 0x0`, that means only in the
default case where RAM voltage is 1.5 Volts. But the RAM voltage
should be changed when configured for the non-default case.

So negate the predicate to alter the RAM voltage for the
non-default cases.

To prevent the build error

    make: *** [coreboot-builds/asus_f2a85-m/cbfs/fallback/romstage_null.debug] Error 1

add `southbridge/amd/agesa/hudson/smbus.c` providing the function
`do_smbus_write_byte` to ROM stage in `Makefile.inc`. That can
actually be used after the needed header files are included in a
previous commit.

The output of `make printall` (look for DEPENDENCIES=) shows which

cbmemc_reinit() no longer needs to be called from romstage

migration infrastructure.

However, the cbmem_console_p is referenced using the

is automatically copied over by calling cbmemc_reinit()
through a callback.

Aaron Durbin 716738a6b8 x86: add cache-as-ram migration option
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.

Paul Menzel 3a1457137e AMD Fam15tn boards: BiosCallOuts.c: Declare codec arrays as `static`
These arrays are declared as `static` for AMD SB800 based boards,
so do the same for this generation.

Rudolf Marek just changed `const CODEC_TBL_LIST` to `static const`
in [1]. Adapt all Fam15tn based boards (AMD Parmer, AMD Thatcher,
ASUS F2A85-M) to keep the differences between them small.

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.

Please note that AGESA seems to define bigger stack sizes. But
these seem to be too much too.

The following command was used to create the patch.

    $ git grep -l STACK_SIZE src/mainboard/ | xargs sed -i '/STACK_SIZE/,+3d'

Stefan Reinauer 3949e37834 Drop CONFIG_AP_CODE_IN_CAR
This option has not been enabled on any board and was considered
obsolete last time it was touched. If we need the functionality,
let's fix this in a generic way instead of a K8 specific way.
This was mostly a speedup hack back in the day.

Dave Frodin 37f8c3af0e cbfs_core.c: make cfbs searches even less verbose
The cbfs core code would print out the name of the file it is
searching for and when it is found would print out the name
again. This contributes to a lot of unnecessary messages in a
functioning payload’s output. Change this message to a DEBUG one
so that it will only be printed when CONFIG_DEBUG_CBFS is enabled.

Paul Menzel ea23a6b23f src/cpu/amd/agesa/Kconfig: Use tabs instead of spaces for alignment
Some entries still used spaces while others used tabulators[1]. Convert
spaces to tabs to uniformly use tabs.

---------------------- 8< -------------- 8< -----------------------------
For all of the Kconfig* configuration files throughout the source tree,
the indentation is somewhat different.  Lines under a "config" definition
are indented with one tab, while help text is indented an additional two
spaces. [2]

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.

As commented by Aaron Durbin, a separate `i82801gx_enable_acpi()` is
not needed: “The existing code path *in this file* is about enabling
the io apic.” [1].

Paul Menzel 1b3e176468 x86 I/O APIC: Dump I/O APIC regs in `ioapic.c`
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.
