After DDR PHY reset de-asserted, DLL automatically starts to
lock, and the lock time is maximum 5.12us. The output clock of
DLL supplies the clocks of DDR controller and PHY digital logic.
So before DLL lock, the clocks of DDR controller and PHY digital
logic are indeterminate. When programming DDR in the period of
DLL unlock, the programming maybe unstable because of the
indeterminate clocks. So we need wait for at least 5.12us after
de-asserting reset, then start to program DDR registers.
10us provide some safety margin.

Some SPI controllers (like Imgtec Pistachio), have a hard limit on SPI
read and write transactions. Limiting transfer size in the wrapper
allows to provide the API user with unlimited transfer size
transactions.
The tranfer size limitation is added to the spi_slave structure, which
is set up by the controller driver. The value of zero in this field
means 'unlimited transfer size'. It will work with existion drivers,
as they all either keep structures in the bss segment, or initialize
them to all zeros.
This patch addresses the problem for reads only, as coreboot is not

Even though coreboot always hardcodes the FMAP offset, the same is not
possible for all other tools that manipulate ROM images. Some need to
manually find the FMAP by searching for it's magic number (ASCII
"__FMAP__"). If we do something like 'memcmp(fmap_buffer, "__FMAP__",
...) in coreboot code, it has the unfortunate side effect that the
compiler will output that very same magic number as a constant in the
.rodata section to compare against. Other tools may mistake this for the
"real" FMAP location and get confused.
This patch reverses the constant defined in coreboot and changes the
only use of it correspondingly. It is not impossible but extremely
unlikely (at the current state of the art) that any compiler would be
clever enough to understand this pattern and optimize it back to a
straight memcmp() (GCC 4.9 definitely doesn't), so it should solve the
problem at least for another few years/decades.

because the code believes the log to be broken at that time. Good thing
we now have a FAFT test for these things that I had of course been too
lazy to run. -.-
The real reason for moving that line was to put it after any point in
elog_init() that could still error out. The problem is that we might add
the "cleared" event before we try to shrink (which can fail and cause an
error)... but those two things cannot happen at the same time, so it
should be okay to flip them around and mark the elog as initialized in

The elog driver has a really stupid bug that checks a result which is
stored in an unsigned variable for < 0. Surprisingly GCC does not catch
this nonsense right now, and I spent an hour trying out different
warning options without finding one that doesn't also bring a load of
stupid and unavoidable false positives (the biggest offender being
-Wtype-limits, which does exactly what we'd want except for flagging
things like if ((u8)var >= CONFIG_VAR_MIN) where the VAR_MIN Kconfig may
or may not be 0).
So, the only thing we can do is fix this one and wait for the next time
something like that blows up. -.- Also change some more code to make the
behavior more explicit (the old code already intended to work this way
since flash_base is statically initialized to 0, never assigned in the
error path and checked later in elog_init()... but there was an error
message that incorrectly claimed a different fallback behavior, and
explicitly assigning the values makes this easier to see). Finally, add
another state to the elog_initialized variable to avoid trying to
reinitialize a broken eventlog on every event (if it doesn't work the
first time, chances are that it won't work later on during the same boot
either).

This patch adds support for Pinky rev3 (board ID 2) and Jerry rev2: the
power button GPIO changed polarity to low, the 5V_DRV pin for USB power
was moved to the AP again (welcome back!), and the EMMC_RST_L is now
finally on a port with the right IO voltage so we don't need any weird
pull-up tricks anymore. Since there are very few Jerry rev1s around,
we'll just move it over to the new code directly without introducing
board ID differences (also, because I have no idea how they stuffed it

LDO7 (VCC10_LCD_PWREN_H) is essentially just a glorified GPIO that turns
the real VCC10 regulator on or off. We tried setting it to 3.3V since it
matches the VCC33_SYS voltage on the input of that regulator. However,
we didn't notice that the LDO only supports going up to 2.5V.
This patch changes the voltage to the allowed maximum, which should
still work fine as an enable line (and is the same value used by the
kernel). This removes an assertion error in the ramstage.
Also change the PMIC driver to assert maximum VSEL values based on the
LDO, because the lower-voltage ones support one more setting. (LDO3 is
actually listed to only go up to 0b1111 in the manual, and has a weird
jump from 0b1101 -> 2.2V (skipping over 0b1110) to 0b1111 -> 2.5V. I
don't know if that's a documentation error or what they were smoking
when they designed that, but we don't need to care for now.)

The eMMC enable pin is in a 3.3V IO domain. Unfortunately the eMMC
expects this pin to be 1.8V. The way we were driving this pin would
cause the eMMC to pull power through this pin and that was causing
current leaks.
In future revisions of hardware we should move this pin somewhere more
legit. However, in the current hardware we can get things working
pretty well by using a pullup to "drive" this pin. This will work in
conjunction with the external 100K pullup to give a somewhat
reasonable voltage. The eMMC will also not be able to pull much
current through this pin, so it can't leak too badly.

The CPU on/off functions are the method for the Kernel to support CPU
hot-plug function in PSCI. To support this, we still need flow controller
support to capture the WFI from the CPU and inform PMC to power gate the
CPU core. On the other path, we turn on the CPU by toggling the PMC and
use flow controller to let go when the power is steady.
BUG=chrome-os-partner:32136
BRANCH=None
TEST=built the kernel with PSCI enabled,
check both of the CPUs are coming up,
test the CPU hot-plug is working on Ryu

With support for initializing registers based on values saved by primary CPU, we
no longer need to invalidate secondary CPU stack cache lines. Before jumping to
C environment, we enable caching and update the required registers.

startup.c provides function to enable CPU in any stage to save register data
that can be used by secondary CPU (for normal boot) or any CPU (for resume
boot). stage_entry.S defines space for saving arm64_startup_data. This can be
filled by:
1) Primary CPU before bringing up secondary CPUs so that the secondary can use
register values to initialize MMU-related and other required registers to
appropriate values.
2) CPU suspend path to ensure that on resume the values which were saved are
restored appropriately.
stage_entry.S provides a common path for both normal and resume boot to
initialize saved registers. For resume path, it is important to set the
secondary entry point for startup since x26 needs to be 1 for enabling MMU and
cache.
This also ensures that we do not fall into false memory cache errors which
caused CPU to fail during normal / resume boot. Thus, we can get rid of the
stack cache invalidate for secondary CPUs.

BRANCH=None
TEST=Compiles and boots both CPU0 and CPU1 on ryu without mmu_enable and stack
cache invalidate for CPU1.
