Vadim Bendebury b7cf11573d storm: need larger CBFS cache
With VPD blob of certain format, CBFS cache on storm proves to be not
large enough. This patch makes it bigger, it is still well above the
area preserved for the NSS.

BUG=chrome-os-partner:32152
TEST=the system now boots with the VPD it used to fail booting.

Vadim Bendebury f32ef133dd storm: fix SW_RESET signal polarity
The actual level required to take the ethernet switch out of reset is
low, not high.

BUG=chrome-os-partner:31780
TEST=with this patch applied, when proto0.2 boots, the ethernet
     switch's LED blink once, as was the case with proto0.

Vadim Bendebury c7bbc04544 storm: deassert SW_RESET signal at startup
The proto0.2 hardware connects gpio26 (sw reset) to the ethernet
switch reset pit. The output stays low (or high-z) after power up,
which holds the switch in reset. Deassert the signal at startup on
hardware rev 1 and later.

Vadim Bendebury 1de971dd32 storm: reset TPM properly on proto0
The proto0 storm hardware has the TPM reset line wired to the SOC GPIO22
pin instead of the system reset. This causes all kind of TPM behavior
problems and requires frequent power cycles. Adding explicit TPM reset
makes all those problems go away.

BUG=chrome-os-partner:30705, chrome-os-partner:30829
TEST=tried resetting proto0 at different moments during boot up - the
     TPM does not fail anymore.

Aaron Durbin b241f57de5 arm64: add smc layer to secmon
In order to process PSCI commands SMC instructions need to be
serviced. Provide a simple way for users of SMC to register their
handlers by function.

The SMC layer hooks into the exception processing, however it only
processes AARCH64 SMC calls. All others are ignored.

BUG=chrome-os-partner:32112

TEST=Added nop smc call to depthcharge. SMC handled and continue booting

Furquan Shaikh 668316bdcc arm64: Add support for transition library
Transition library provides the following functionalities:
1) Setup the environment for switching to any particular EL and jump to the
loaded program at that EL. In short "Execute program X at exception level Y
using the state Z"
2) Provides routines for exception entry and exception exit that can be used by
any program to implement exception handling. The only routine required by the
program would be exc_dispatch which handles the exception in its own required
way and returns by making a call to exc_exit. On exc_exit, the transition
library unwinds the whole stack by popping out the saved state of xregs

If mmu_init is called more than once then, free_idx should be reset to

Tom Warren cbf17d95c5 rush: Add cpu devices to devicetree
Rush builds were throwing a _sync_sp_el0 exception due
to commit 65af2f3d (tegra132: support arm64 SMP bringup).
Fixed by copying over the rush_ryu devicetree.db, which
adds all the CPUs to the device tree. Basically the same
as commit 8f61ca2da but for rush.

BUG=None
BRANCH=None
TEST=Booted rush OK, brought up rush kernel from USB.
