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.

In the process of streamlining coreboot code and getting
rid of unneeded ifdefs, drop a number of unneeded checks
for the GNU C compiler. This also cleans up x86emu/types.h
significantly by dropping all the duplicate types in there.

asrock/e350m1: reduce default stack size
The stack used on the ASRock E350M1 is significantly less than
what we currently set (64k per core). In fact, we use about half
of the default stack size (4k) on core 0 and even less on non
BSP cores [1]:
$ grep stack coreboot_without_patch_but_monotonic_timer.log
CPU1: stack_base 002a0000, stack_end 002afff8
CPU1: stack: 002a0000 - 002b0000, lowest used address 002afda8, stack used: 600 bytes

[…]

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

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.

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.

The current way to get a simple mono_time difference is:
1. Declare a rela_time struct
2. Assign it the value of mono_time_diff(t1, t2)
3. Get microseconds from it using rela_time_in_microseconds().
This patch adds a simpler method. Now one only needs to call
mono_time_diff_microseconds(t1, t2) to obtain the same value which
is produced from the above three steps.

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.

The "gigabit ethernet controller" (GEC) block was added to AMD
Hudson A55E to integrate ethernet capabilities into an AMD
southbridge.
The GEC is designed to work with B50610 and B50610M gigabit PHY
chips from Broadcom. These parts may not be generally available
in small quantities for embedded development.
The GEC block requires an opaque firmware blob to function. The
GEC blob is controlled by AMD and Broadcom and is not available
from coreboot.org.
This change removes GEC support from AMD Parmer and AMD Thatcher
mainboards since these boards do not have the Broadcom PHY.
AMD has requested that the GEC be hidden for Hudson FCH since
the PHY parts are not generally available. This Kconfig option
can make it appear that this is a viable and supported way to
add Ethernet to an embedded board. It is possible to use the
Hudson GEC block with other PHYs, but this requires development
of a custom GEC blob and a custom Ethernet driver. A custom GEC
blob has been developed for a Micrel PHY, but there is no
accompanying driver.

provide a barrier to the following states so that timers are drained
before proceeding. This allows for blocking state traversal for key
components of boot.
BS_OS_RESUME
BS_WRITE_TABLES
BS_PAYLOAD_LOAD
BS_PAYLOAD_BOOT
Future functionality consists of evaluating the timer callbacks within

seems to take 90% of the boot time. The timer callbacks could then be
ran in a more granular manner.

the typical policy is that the boot cpu is the only one with

Therefore, utilize the boot state callbacks to schedule the disabling

The boot flow currently has a fixed ordering. The ordering
is dictated by the device tree and on x86 the PCI device ordering
for when actions are performed. Many of the new machines and
configurations have dependencies that do not follow the device
ordering.
In order to be more flexible the concept of a boot state machine
is introduced. At the boundaries (entry and exit) of each state there
is opportunity to run callbacks. This ability allows one to schedule
actions to be performed without adding board-specific code to

Enable `EARLY_CBMEM_INIT` for CBMEM console support by looking how
other boards do this.
This commit is tested by enabling the CBMEM console (`CONSOLE_CBMEM` in
Kconfig) and then in GRUB 2 (as a payload) with the cbmemc command from
the cbmemc module and in userspace with ./cbmem -c. Both worked.

The DDR3 memory initialization (with "mem_reset" set on normal boot) will cause
resume to be unstable, especially when X is running. System may show X screen
for few seconds, then crash randomly and unable to recover - although text
console may still work for a while. Probably caused by corrupted memory pages.
'mem_reset' (which refers to RESET# in DDR3 spec) should be enabled according
to DDR3 spec. But it seems that on Exynos 5, memory can be initialized without
setting mem_reset for both normal boot and resume - at least no known failure
cases are found yet. So this can be a temporary workaround.
Verified by booting a Google/Snow device with X Window and ChromeOS, entering
browser session with fancy web pages, closing LID to suspend for 5 seconds, then
re-opening to resume. Suspend/resume worked as expected.
Also tried the "suspend_stress_test" with X running and finished 100 iterations
of suspend/resume test without failure.

Add a safety check in function `intel_update_microcode` to return when
accidentally `NULL` is passed as `microcode_updates`, which would lead
to a null pointer dereference later on.
for (c = microcode_updates; m->hdrver; m = (const struct microcode *)c) {
While at it, use `return NULL` for clarity in function
`intel_microcode_find` and include the header file `stddef.h`. for it.
The review of this patch had some more discussion on adding more
comments and more detailed error messages. But this should be done in
a separate patch.
For clarity here some history, on how this was found and what caused
the discussion and confusion.
Originally when Vladimir made this improvement, selecting
`CPU_MICROCODE_IN_CBFS` in Kconfig but not having the microcode blob
`cpu_microcode_blob.bin` in CBFS resulted in a null pointer dereference
later on causing a crash.
for (c = microcode_updates; m->hdrver; m = (const struct microcode *)c) {
Vladimir fixed this by returning if `microcode_updates` is `NULL`,
that means no file is found and successfully tested this on his
Lenovo X201.
When pushing the patch to Gerrit for review, the code was rewritten
though by Aaron in commit »intel microcode: split up microcode loading
stages« (98ffb426) [1], which also returns when no file is found. So
the other parts of the code were checked and the safety check as
described above is added.

This makes sure that the product ID (PRO_ID) register can be read
when the OS kernel is figuring out what kind of CPU it's running on.
For historical reference, the original U-Boot code seems to have
worked basically by accident here. The hardware has a quirk where by
reading the value before gating the IP block keeps the value
persistent. U-Boot reads the chip ID early on to distinguish between
chip family, but we do not mix code the same way so we do not read
the chip ID. Since the value has been read before the clock gating
happens, the value remains available for the kernel to use during the
decompression stage. We don't want to rely on that behavior when using
coreboot. Instead the kernel should gate unused IPs.
(credit to Gabe for finding symptom in the kernel)

[…]
romstage-y += cfg.c

ramstage-y += cfg.c

[…]
`src/southbridge/amd/cimx/sb800/` is passed with the switch `-I` to
the compiler, where it is also going to find the header file
`sb_cimx.h`. Therefore use `#include <sb_cimx>` everywhere, which is
what some AMD SB800 based boards already do.
The only effect is, that the compiler will not needlessly look into
directories which do not contain the header file [1].
The following command was used for the replacement.
$ git grep -l sb_cimx.h src/mainboard/ | xargs sed -i 's/#include "sb_cimx.h"/#include <sb_cimx.h>/'

Because pointers can be 32bit or 64bit big,
using them in the coreboot table requires the
OS and the firmware to operate in the same mode
which is not always the case. Hence, use 64bit
for all pointers stored in the coreboot table.
Guess we'll have to fix this up once we port to
the first 128bit machines.

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.
