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.

1. Move comment for console init to correct place.
2. Start output with capital letter and add full stop at the end.
3. Add missing »)« at the end of description of GPIO 10.
4. Use tabulators instead of spaces.
5. Indent the code automatically using GNU indent [1] with the `-sc`
switch adding stars in front of comment blocks as the good indent
manual documents.
$ indent -linux -sc src/mainboard/lenovo/x60/romstage.c
Leave the numbers left aligned as it is more beneficial to be
able to run indent without adapting the result afterward.

This reverts commit 2fde9668b47e74d1bfad2f1688a4481e6b966d04
Somehow this got merged before its dependencies. 3190 must be merged first, followed by 3176. However 3190 will fail while this patch is in. So the situation can't correct itself.
Reverting this until the other two go in.

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.

The notion of loading a payload in the current boot state
machine isn't actually loading the payload. The reason is
that cbfs is just walked to find the payload. The actual
loading and booting were occuring in selfboot(). Change this
balance so that loading occurs in one function and actual
booting happens in another. This allows for ample opportunity
to delay work until just before booting.

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.

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.

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
the shared boot flow.

While debugging a crash it was discovered that ld was inserting
address space for sections that were empty depending on section
address boundaries. This led to the assumption breaking down that
on-disk payload (code/data bits) was contiguous with the address
space. When that assumption breaks down relocation updates change
the wrong memory. Fix this by making the rmodule.ld linker script
put all code/data bits into a payload section.

The "console_init" does initialize UART driver (which will setup peripheral and
pinmux) and print starting message. Duplicated initialization can be removed.
Also, console_init (from console.c) is always linked to bootblock (and will do
nothing if CONFIG_EARLY_CONSOLE is not defined) so it's safe to remove #ifdef.
Verified by building and booting on Google/Snow, with and without
CONFIG_EARLY_CONSOLE.

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)

Because pointers can be 32bit or 64bit big,
using them in the coreboot table requires the

which is not always the case. Hence, use 64bit

Guess we'll have to fix this up once we port to

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.

This function isn't yet used for much, or perhaps anything, but where it

that are being ored in can be expressed and this function can stay dormant
until it actually has something to do.

When looking into possible reasons for a proposed revert [1], I noticed
that the comments use four arguments for `PCIE_DDI_DATA_INITIALIZER`,
but the actual definition only uses three.
$ git grep -A1 PCIE_DDI_DATA_INITIALIZER # manually squeeze whitespace in output
[…]
--
src/vendorcode/amd/agesa/f10/AGESA.h:#define PCIE_DDI_DATA_INITIALIZER(mConnectorType, mAuxIndex, mHpdIndex ) \

[…]
So remove the fourth argument in the comments. Luckily the compiler,
at least gcc, warns about a wrong number of arguments, and therefore
no incorrect code resulted from the wrong documentation.

Now users can use a different compiler from GCC like Clang by for example
doing `CC=clang make`.

In [1] Idwer Vollering noted, that the type `u64` is not portable so
on his FreeBSD system, the following warning is shown.
$ clang -O2 -Wall -W -I/usr/local/include -c -o amb.o amb.c
amb.c:441:22: error: use of undeclared identifier 'u64'
ambconfig_phys = ((u64)pci_read_long(dev16, 0x4c) << 32) |
The type `uint64_t` seems to be defined also on FreeBSD, so using this
fixes the warning.
Note, this warning is not reproducable with Debian Sid/unstable for
example. I have no idea why though.
