0457b5dce1 baytrail: Fix XHCI controller reset on resume
The toggling of XHCIBAR+80E0h[24] appears to cause the XHCI
controller to be reset on resume.  This causes the kernel to
have to reinitialize the controller and all devices.

It seems this bit should only be toggled on boot path, in
the resume path it should be left as 0.

Additionally after routing ports to XHCI don't issue a port
reset to the ports in the resume path.

4a3f2e45e0 arm: Put assembly functions into separate sections
This patch changes the ENTRY() macro in asm.h to create a new section
for every assembler function, thus providing dcache_clean/invalidate_all
and friends with the same --gc-sections goodness that our C functions
have. This requires a few minor changes of moving around data (to make
sure it ends up in the right section) and changing some libgcc functions
(which apparently need to have two names?), but nothing serious.

(You may note that some of our assembly functions have data, sometimes
even writable, within the same .text section. This has been this way
before and I'm not looking to change it for now, although it's not
totally clean. Since we don't enforce read-only sections through paging,
it doesn't really hurt.)

BUG=None
TEST=Nyan and Snow still boot. Confirm dcache_invalidate_all is not
output into any binary anymore since no one actually uses it.

07a35925dc arm: Redesign, clarify and clean up cache related code
This patch changes several cache-related pieces to be cleaner, faster or
more correct. The largest point is removing the old
arm_invalidate_caches() function and surrounding bootblock code to
initialize SCTLR and replace it with an all-assembly function that takes
care of cache and SCTLR initialization to bring the system to a known
state. It runs without stack and before coreboot makes any write
accesses to be as compatible as possible with whatever state the system
was left in by preceeding code. This also finally fixes the dreaded
icache bug that wasted hundreds of milliseconds during boot.

CQ-DEPEND=CL:183877
BUG=None
TEST=Snow and Nyan still boot. Time between entering romstage main() and
the configure_l2ctlr() call on Nyan drops from 390ms to 0.3ms. Even with
icache turned on the old implementation took 7.8ms since it cleared the
cache multiple times with a slow algorithm.

6d94f83301 arm: Fix up new cache flush algorithm and replace dcache_*_all() with it
This patch fixes the remaining few bugs in our shiny new cache iteration
by set/way/level algorithm to actually make it work: It makes it start
from cache level 0 (previously it would always start at LoC and be
"done" instantly), fixes up the two shifts that isolate the set bits at
the end (which didn't seem to account for the fact that the first shift
affects the second), and throws an S bit on that last shift so that it
actually affects the conditionals after it.

In addition, also moves the next_level block to the top so that we can
share (and thus eliminate) some code at initialization, and turns the
whole thing into a thrice-instantiated macro to create functions that
fit our existing interface.

BUG=None
TEST=Ran with cache_test code (see separate CL) and closely examined the
resulting output. Made sure results look as expected (iterating through
all sets (inner) and ways (outer) for L1 and then L2 cache, extracting
the right numbers from CLIDR and CCSIDR, not touching anything twice).
Time for a single dcache_clean_invalidate_all() on Nyan drops from 3.7ms
to 0.3ms.

4698467320 arm: Import armv7_dcache_wbinv_all function from NetBSD
This patch pulls in NetBSD's full cache flushing algorithm for ARM, to
replace our old, slow and slightly overzealous C-only implementation.
It's a beautiful piece of code that manages to run on only caller-saved
registers (meaning it doesn't need to write to memory) in a very tight
loop, and it's BSD-licensed to boot (which we need for libpayload).
Unfortunately it's also not quite correct, but I can fix that. Pulling
the original in a separate commit to make it more obvious what changes
are mine.

35e5c5e473 nyan_big: use RAM_CODE[3:2] for ram code
Cherry-picking https://chromium-review.googlesource.com/183833 for nyan_big.

BootROM uses RAM_CODE[3:2] value as index to retrieve boot device
array in BCT to reconfigure device. Since there will be one kind
of boot device, we can reuse RAM_CODE[3:2] in conjunction with
RAM_CODE[1:0] to select up to 16 RAM parameters. To support this
change without leading BootROM to read wrong boot device parameters,
we need to fill up boot device array.

8e3bb34d4a tegra124: Never touch MEM(MC)/EMC clocks in ramstage.
The clocks for MEM(MC)/EMC should be either initialized by BootROM, or in the
step of SDRAM initialization. Changing their states in ramstage may cause
unexpected results (note MC even always ignores RESET states).

To make it clear, we should remove MEM/EMC from the clock initialization list.

a6b85ad950 baytrail: Add basic support for ACPI System Wake Source
This adds the very basic top-level support for determining the
system wake source from ACPI.  It only implements the _SWS method
in the _SB scope which just returns a bit index into the PM1
status register for the first fixed functional block.

This can be used to determine wake source of RTC or Power Button
but does not help determine wake source for USB or GPIO.

The ACPI spec says to return -1 if no source can be determined
from PM1 status register.

BUG=chrome-os-partner:8127
BRANCH=baytrail
TEST=build and boot on rambi

1) Test resume from S3 by RTC:
ACPI System Wake Source is PM1 Index 10
(bit 10 is RTC_STS in ACPI spec, ACPI_EVENT_RTC in kernel)

2) Test resume from S3 by power button:
ACPI System Wake Source is PM1 Index 8
(bit 8 is PWRBTN_STS in ACPI spec, ACPI_EVENT_POWER_BUTTON in kernel)

3) Test resume from S3 by USB:
ACPI System Wake Source is PM1 Index -1
