81193e6cd8 storm: add code for detecting rec/dev/write protect switches' status
The gpio access code has been moved to a separate file to match other
platforms. Accessor functions are added to read different switches
state. They will be read by verstage, when it is enabled, and by
ramstage, for passing the values to depthcharge.

It is unfortunate that the gpio values are not being cached and can
change by the time CBMEM table is filled, but we have to live with
that for now.

44cf870cb0 timer: Reestablish init_timer(), consolidate timer initialization calls
We have known for a while that the old x86 model of calling init_timer()
in ramstage doesn't make sense on other archs (and is questionable in
general), and finally removed it with CL:219719. However, now timer
initialization is completely buried in the platform code, and it's hard
to ensure it is done in time to set up timestamps. For three out of four
non-x86 SoC vendors we have brought up for now, the timers need some
kind of SoC-specific initialization.

This patch reintroduces init_timer() as a weak function that can be
overridden by platform code. The call in ramstage is restricted to x86
(and should probably eventually be removed from there as well), and
other archs should call them at the earliest reasonable point in their
bootblock. (Only changing arm for now since arm64 and mips bootblocks
are still in very early state and should sync up to features in arm once
their requirements are better understood.) This allows us to move
timestamp_init() into arch code, so that we can rely on timestamps
being available at a well-defined point and initialize our base value as
early as possible. (Platforms who know that their timers start at zero
can still safely call timestamp_init(0) again from platform code.)

4913cb78d2 storm: Fix timer init order problem
Commit 257aaee9e3a (arm: Add bootblock_mainboard_early_init() for
pre-console initialization) inadvertently moved the timer initialization
after console initialization for IPQ806x, which is apparently not a good
idea for this platform. This patch solves the issue by moving
init_timer() to bootblock_mainboard_early_init(), which is the new hook
explicitly provided to perform pre-console tasks.

BUG=None
TEST=Built and booted Storm with 257aaee9e reverted. Noticed that it was
already broken. Bisected coreboot and tracked down breakage to commit
a126a62f (ipq8064: use the new utility to build bootblock). Built and
booted successfully with this patch and a revert of a126a62f to confirm
that the bug in question here is fixed.

ec5e5e0db2 New mechanism to define SRAM/memory map with automatic bounds checking
This patch creates a new mechanism to define the static memory layout
(primarily in SRAM) for a given board, superseding the brittle mass of
Kconfigs that we were using before. The core part is a memlayout.ld file
in the mainboard directory (although boards are expected to just include
the SoC default in most cases), which is the primary linker script for
all stages (though not rmodules for now). It uses preprocessor macros
from <memlayout.h> to form a different valid linker script for all
stages while looking like a declarative, boilerplate-free map of memory
addresses to the programmer. Linker asserts will automatically guarantee
that the defined regions cannot overlap. Stages are defined with a
maximum size that will be enforced by the linker. The file serves to
both define and document the memory layout, so that the documentation
cannot go missing or out of date.

The mechanism is implemented for all boards in the ARM, ARM64 and MIPS
architectures, and should be extended onto all systems using SRAM in the
future. The CAR/XIP environment on x86 has very different requirements
and the layout is generally not as static, so it will stay like it is
and be unaffected by this patch (save for aligning some symbol names for
consistency and sharing the new common ramstage linker script include).

BUG=None
TEST=Booted normally and in recovery mode, checked suspend/resume and
the CBMEM console on Falco, Blaze (both normal and vboot2), Pinky and
Pit. Compiled Ryu, Storm and Urara, manually compared the disassemblies
with ToT and looked for red flags.

11c4c92d91 ipq8064/storm: UART enable and various fixes
The original patch from chromium was  a bit of a mishmash.
Between that, rebasing and using the coreboot.org UART infrastructure,
the patch has changed a bit from the original. It seems reasonable to
keep these changes together.
- build in the ipq UART and turn on bootblock console
- sets LPAE and ROM header address
- adds cpd.c to storm

The original commit:
ipq8064: make UART driver work in bootblock

This patch it the last one in the chain adapting the ipq9064 UART
driver for use in coreboot. A new config option
(CONSOLE_SERIAL_IPQ806X) is being introduced to control inclusion of
the driver.

The previously introduced uart_wrapper.c is now included in the build
to provide the console driver structure used by ramstage.

Necessary configuration options are added to allow use of UART in the
bootblock.

BUG=chrome-os-partner:27784

TEST=with this change the coreboot image on AP148 prints a banner on
   start up:

coreboot-4.0 Wed Apr 23 16:24:51 PDT 2014 starting...
