The punit is responsible for a number of things. Without
performing the sequence included it won't change processor
frequency when requested and apparently there are some bizarre
hangs introduced if this sequence isn't included either. Lastly,
this needs to come after microcode has been loaded. As that is
done in bootblock the ordering is correct.
One other side effect is that this fixes the graphics devices'
device id. Before it was showing up as the same device id of the
SoC transaction router.

Modified register contains SPI frequency for 'Normal Read' command

unintentionally clears these bits, increasing SPI frequency to 66MHz

This completes the improvements to the ELF file parsing code. We can
now parse section headers too, across all 4 combinations of word size
and endianness. I had hoped to completely remove the use of htonl
until I found it in cbfs_image.c. That's a battle for another day.
There's now a handy macro to create magic numbers in host byte order.
I'm using it for all the PAYLOAD_SEGMENT_* constants and maybe
we can use it for the others too, but this is sensitive code and
I'd rather change one thing at a time.
To maximize the ease of use for users, elf parsing is accomplished with
just one function:
int
elf_headers(const struct buffer *pinput,
Elf64_Ehdr *ehdr,
Elf64_Phdr **pphdr,
Elf64_Shdr **pshdr)
which requires the ehdr and pphdr pointers to be non-NULL, but allows
the pshdr to be NULL. If pshdr is NULL, the code will not try to read
in section headers.
To satisfy our powerful scripts, I had to remove the ^M from an unrelated
microcode file.

The AGESA resumes the GPP ports in the romstage using FchInitResetGpp(),
which does FchGppPortInitS3Phase() for S3 resume. The PreInitGppLink()
looks into CMOS to figure out what ports to just force to Gen1 or
Gen2 PCIe. Then boot continues and in the ramstage the rest of GPP
init is executed. There is a problem that nobody sets properly the
PortDetected flags in the S3 path. As the consequence FchGppDynamicPowerSaving()
thinks the GPP port is not enabled and shut downs it.
The best fix would be also to remove the CMOS dependency which
might be some left over, because AGESA does not use CMOS much for
anything else. There could be also some way how to pass the GPP state
structure from romstage to ramstage possibly via hudson/resume.c
but I don't know how to do that. Similar problem is that the "late"
stage of init again "forgets" the PortDetected state.
This fix fixes the resume issue on Asus F2A85-M. With this patch applied
both GPP ports (used as PCIe x1 and internal ethernet) are working again
after resume.

Provide a common entry point for bringing up the APs
in parallel. This work is based off of the Haswell one
which can be moved over to this in the future. The APs
are brought up and have the BSP's MTRRs duplicated in
their own MTRRs. Additionally, Microcode is loaded before
enabling caching. However, the current microcode loading
support assumes Intel's mechanism.
The infrastructure provides a notion of a flight plan
for the BSP and APs. This allows for flexibility in the
order of operations for a given architecture/chip without
providing any specific policy. Therefore, the chipset
caller can provide the order that is required.

Improve clang compatibility by dropping an opaque hack
The section attribute was only ever meant for specifying
section names, not their properties - otherwise they would
have provided section(name,attribute,class) instead of only
section(name).
The hack to add attribute and class to the name, and commenting
out the "real" definitions inserted by the compiler (see the
terminating "#"), is refused by clang developers.
This is a cleaner implementation in that the section is first
declared with its properties, then used later-on, expecting that
later conflicting declarations are ignored.
It can still break in two ways:
1. The assembler or linker could complain about a section declared
in two different ways.
2. The assembler could just use the latest declaration, not the first,
to determine the section's properties.
I won't sort these out unless they actually happen.

The sequence to inject microcode updates is virtually the same for all
Intel CPUs. The same function is used to inject the update in both CBFS
and hardcoded cases, and in both of these cases, the microcode resides in
the ROM. This should be a safe change across the board.
The function which loaded compiled-in microcode is also removed here in
order to prevent it from being used in the future.
The dummy terminators from microcode need to be removed if this change is
to work when generating microcode from several microcode_blob.c files, as
is the case for older socketed CPUs. Removal of dummy terminators is done
in a subsequent patch.

This change allows Kconfig options ROM_SIZE and CBFS_SIZE to be
set with values that are not power of 2. The region programmed
as WB cacheable will include all of ROM_SIZE.
Side-effects to consider:
Memory region below flash may be tagged WRPROT cacheable. As an
example, with ROM_SIZE of 12 MB, CACHE_ROM_SIZE would be 16 MB.
Since this can overlap CAR, we add an explicit test and fail
on compile should this happen. To work around this problem, one
needs to use CACHE_ROM_SIZE_OVERRIDE in the mainboard Kconfig and
define a smaller region for WB cache.
With this change flash regions outside CBFS are also tagged WRPROT
cacheable. This covers IFD and ME and sections ChromeOS may use.

Even though the Allwinner A10 is limited to a 24KiB bootblock, the
memory initialization takes only about 3KiB and leaves enough room for
an MMC or NAND driver, so init the memory early on. The advantage is
that we can eliminate complicated logistics of where to cache CBFS and
where to load the ramstage in SRAM.

The CPU was clocked at 384MHz in the bootblock, but the AHB bus has a

Rather than having to track which bit in which register should be
cleared or set to gate or ungate the clock to a certain peripheral,
provide a simplified enum which encodes the register and bit. This
change comes with a function which decodes the enum and gates/ungates
the clock.
This also removes the register-dependent bitmasks for APB0 and APB1
gating registers.

The end of the _PS0 method that is supposed to transition the
XHCI device to D0 state is instead putting it in D3 state.
This triggers a PME_B0 GPE which causes a Notify to the XHCI
ACPI Device in the kernel and that increments the wakeup counter
and causes aborted suspends.
Instead if we just leave the device in D0 where it should be
after executing this function then the PME_B0 is not generated
and the kernel does not see a wakeup on XHCI.
Similarly I changed the _PS3 method to always put the device in
D3 at the end of the method, rather than depending on the state
to be D3 at the start.
Before this change the kernel would see the following sequence
when trying to suspend when the XHCI controller is in D3cold:
kernel: ACPI: Execute Method [\_SB_.PCI0.XHCI._PS0] (Node ffff88017802bf28)

kernel: PM: Wakeup pending, aborting suspend
kernel: last active wakeup source: 0000:00:14.0
Now it does not get a notification (due to PME_B0) when going to D0
on the way into suspend. XHCI goes from D3cold to D0 (in order to
be able to read mmio) and then back to D3hot before suspend.

The recommended value in docs is D2, but lynxpoint XHCI does not even
support D2 state which causes the kernel to think this device cannot
be used as a wake source:
kernel: xhci_hcd 0000:00:14.0: System wakeup enabled by ACPI
kernel: ACPI: Device does not support D2
kernel: xhci_hcd 0000:00:14.0: System wakeup disabled by ACPI
Additionally this means the kernel will never put the device into D3
state by itself. There is SMI code that will put the device into D3
before suspend so advertising D3 here should be correct.
With this change the kernel will put the controller into D3 on suspend
and back to D0 on resume, including executing the ACPI methods
for _PS0/_PS3 that contain chipset specific workarounds.
In addition add a _PSC method to directly return the D state from the
device registers. With ALL USB devices removed the XHCI controller
goes into D3 state and the kernel can have a hard time determining
the state of the device at boot.
A kernel compiled with CONFIG_ACPI_DEBUG=y and module parameters
acpi.debug_layer=0x7f acpi.debug_level=0x2f can be used to see

This commit adds a new Kconfig option for the LynxPoint
southbridge that will have coreboot route all of the USB
ports to the XHCI controller in the finalize step (i.e.
after the bootloader) and disable the EHCI controller(s).
Additionally when doing this the XHCI USB3 ports need
to be put into an expected state on resume in order to make
the kernel state machine happy.
Part of this could also be done in depthcharge but there
are also some resume-time steps required so it makes sense
to keep it all together in coreboot.
This can theoretically save ~100mW at runtime.
Verify that the EHCI controller is not found in Linux and

This reads the clock select field for MUX_ACLK_66_SEL in the
CLK_SRC_TOP1 register in order to obtain the source clock rate
for I2C peripherals. Before we were always assuming that the source
was the MPLL.
Unfortunately not all fields in the CLK_SRC_TOPn registers are
enumerated the same with regard to clock select. So this is just
a one-off for now.

This re-factors clock_get_periph_rate() to be a simpler and also
make a few corrections along the way. To summarize:
- clk_bit_info is no longer used. It had numerous errors and was
really painful anyway since it was just a bunch of opaque magic
numbers that made bugs non-obvious.
- Clock source bitfields for peripherals handled in the switch
statement are 3 bits, not 4. Some divider values are 3 bits,
some are 4. The earlier code always assumed 4 bits for both
which included reserved bits in many cases.
- UART source clock and divider shift values were wrong.
- PWM clock divider was being read from the wrong register.
- SPI3 divider value was being read from the wrong register.
- There was a really confusing calculation for SDMMC0 and SDMMC2
clock rates, but it was never actually used since the switch
statement never handled PERIPH_ID_SDMMC{0,2} and would thus
return if they were ever passed into this function.

This adds a helper function to translate between peripheral clock
select fields in clock source registers and PLLs. Some of this was
already done to handle a few special cases, this generalizes the
earlier work so that follow-up patches can do further clean-up.
Unfortunately, the PLLs represented by clock select fields in
various modules are not uniformly ordered. So for now we focus on
peripheral clock sources only.

This patch implements the basic infrastructure required to use the USB
A-A firmware upload feature on Exynos5 processors with Coreboot. It will
require a corresponding host-side script that activates the feature and
uploads the correct image parts in the correct order to harcoded target
addresses, as described in the comments of alternate_cbfs.c.
Also fixes a bug in the Google Snow mainboard where it would not
correctly initialize the pinmux configuration for the SPI flash bus.
During a normal SPI boot the IROM would already do that for you, but
when booting from USB you have to do it yourself.

The existing GPIO config routines for SDMMC0-2 are over-generalized
and somewhat confusing as a result. It would work nicely if all SDMMC
ports were configured in the same fashion, but there are a few
exceptions.
For example, the inner function runs differently if we're using 8 bits
of data instead of 4, so a big chunk is skipped for SDMMC2. SDMMC0
requires SD_0_CDn to be an output rather than alternate function and
must have a value set.
This patch trades some verbosity for simplicy. Now the SDMMC GPIO
configuration a straight-forward sequence of GPIO operations
without any exceptions.
