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.

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.

Secondary CPUs were intermittently not coming online as expected.
Upon investigation it was found that a cache line needed to be
invalidated that corresponded to the top of the stack for the
failing CPU.
Currently the secondary CPUs come online with caching disabled.
However, the code paths are using C and thus the stack it is assigned.
The MMU is enabled in C after it's pushed its return path onto the
stack that went directly to ram. When the cache line corresponding
to its stack is valid in the cache it will hit once the MMU is enabled.
That hit will have invalid data w.r.t. the return addresses pushed
directly into ram.
This is not the best solution as the only way to guarantee we don't
hit such a situation is to tightly manage resource usage up until
the point of MMU enablement. That can be done in a followup patch.

This patch adds a few retries to NVRAM read/write transactions with the
EC. Failing to read the NVRAM is not fatal to the boot, but it's still
pretty bad... especially since a single initial read failure will cause
vboot to blindly reinitialize the whole NVRAM with zeroes, destroying
important configuration bits like dev_boot_usb. The current EC
transaction timeout is one second, so the three retries added here can
potentially increase boot time by three seconds per transaction... but
this shouldn't happen in any normal case anyway, and if there are errors
a little extra wait is probably preferrable to nuking your NVRAM.
(Also, added a missing newline to an error message in the EC code.)

Looks like Intel has added two more USB 2.0 ports from LynxPoint to
Broadwell, which shifted the port offsets of the USB 3.0 ports behind
them. The USB 2.0 ports are now 0x480 to 0x520 and the 3.0 ones 0x530 to
0x560 (at least according to what my kernel seems to think). The offset
of the first USB 3.0 port is hardcoded and seems to have been copied
over without accounting for this, meaning when we try to operate on all
USB 3.0 ports we actually operate on the last two 2.0 and the first two
3.0 ports instead.
This patch should fix the bug for now. In the future, we might want to
consider dynamically detecting port locations through the Protocol
Capability structures at the end of the XHCI register set instead.
