The current implementation of secmon assumes just entry/arg

We have two drivers for a 100%-identical peripheral right now, mostly
because we couldn't come up with a good common name for it back when we
checked it in. That seems like a pretty silly reason in the long run.
Both Tegra and Rockchip SoCs contain UARTs that use the common 8250
register interface (at least for the very basic byte-per-byte transmit
and receive parts we care about), memory-mapped with a 32-bit register
stride. This patch combines them to a single 8250_mmio32 driver (which
also fixes a problem when booting Rockchip without serial enabled, since
that driver forgot to check for serial initialization when registering
its console drivers). The register accesses are done using readl/writel
(as Rockchip did before), since the registers are documented as 32-bit
length (with top 24 bits RAZ/WI), although the Tegra SoC doesn't enforce
APB accesses to have the full word length. Also fixed checkpatch stuff.
A day may come when we can also merge this driver into the (completely
different, with more complicated features and #ifdefs) 8250 driver for
x86 (which has MMIO support for 8-bit register stride only), both here
and in coreboot. But it is not this day. This day I just want to get rid
of a 99% identical file without expending too much effort.

the usb_scan_pci_bus routine gets into an infinite recursive loop
which ends only when the heap or stack is exhausted. This patch
verifies that the PCI bridge is enabled by verifying that it is

In order to properly support more arm64 SoCs PSCI needs
to handle the hierarchy of cpus/clusters within the SoC.
The nodes within PSCI are kept in a tree as well as
a depth-first ordered array of same tree. Additionally,
the PSCI states are now maintained in a hierachal manner.
OFF propogates up the tree as long as all siblings are
set to OFF. ON propogates up the tree until a node is
not already set to OFF.
The SoC provides the operations for determining how many
children are at a given affinity level. Lastly, the
secmon startup has been reworked in that all non-BSP CPUs
wait for instructions from the BSP.

C0_COUNT register is a free running counter clocked by the CPU
frequency divided by two. On the FPGA board it results in 25 MHz, on
real SOCs it will have to be figured out later.
Some magic addresses and numbers are used to find out if the code is
running on the FPGA board.
timestamp_get() and timer_monotonic_get() are kept in the same file.
The CPU initialization makes sure that CO COUNT is in fact enabled and
starts from zero.

This patch is the start of a series to change all non-x86 SoC-specific
headers to be included as <soc/header.h> instead of the old
<soc/vendor/chip/header.h> or "header.h". It will add an include/soc/
directory under every src/soc/vendor/chip/ and append the .../include/
part of that to the global include path.
This matches the usage of <arch/header.h> for architecture-specific
headers and had already been done for some headers on Tegra. It has the
advantage that a source file which does not know the specific SoC used
(e.g. Tegra files common for multiple chips, or a global include file)
can still include SoC-specific headers and access macros/types defined
there. It also makes the includes for mainboard files more readable, and
reduces the chance to pull in a wrong header when copying mainboard
sources to use a different-related SoC (e.g. using a Tegra124 mainboard
as template for a Tegra132 one).
For easier maintainability, every SoC family is modified individually.
This patch starts out by changing Rk3288. Also alphabetized headers in
affected files since we touch them anyway.
BUG=None
TEST=Whole series: compared binary images for Daisy, Nyan_Blaze,
Rush_Ryu, Storm, Urara and Veyron_Pinky. Confirmed that they are

Paging code is tricky and figuring out what is wrong with it can be a
pain. This patch tries to ease the burden by giving a little more
information for prefetch and data aborts, dumping the Instruction Fault
Address Register (IFAR), Instruction Fault Status Register (IFSR) and
Auxiliary Instruction Fault Status Register (AIFSR) or the respective
Data registers. These contain additional information about the cause of
the abort (internal/external, write or read, fault subtype, etc.) and
the faulting address.
BUG=None
TEST=I have read through enough imprecise asynchronous external abort
reports with this patch that I learned the bit pattern by heart.

Remember the XN bit? The one we had so much fun with on Nyan (LPAE)
because not setting it allows random instruction prefetches to device
memory that hang the system every few thousand boots? Thankfully, we had
always been setting it in the non-LPAE MMU code already...
"When the XN bit is 1, a Permission fault is generated if the processor
attempts to execute an instruction fetched from the corresponding memory
region. However, when using the Short-descriptor translation table
format, the fault is generated only if the access is to memory in the
Client domain, see Domains[...]" - ARM A.R.M. section B3.7.2
Oops. This patch changes our Domain Access Control Register (DACR) to
set domain 0 (the only one we are using) to Client. This means that
access permissions (AP[2:0] bits) become enforced, but they are already
set to full access (0b011). It also means that non-LPAE systems will not
be allowed to execute from DCACHE_OFF memory with enabled MMU anymore.
As far as I can see, Veyron_Pinky has been the only board that does
that.
BUG=chrome-os-partner:32118
TEST=Booted Veyron_Pinky with MMU in the bootblock, saw hangs that look
like spurious prefetches and confirmed that this patch fixes them.
