The GIC is ARM's "Generic Interrupt Controller". This
change essentially implements the rudimentary support
for a GICv2 implementation that routes all interrupts
to Group1. This should also work for GICv1 with security
extensions.

This code ports antirollback module and tpm library from platform/vboot_reference.
names are modified to conform to coreboot's style.
The rollback_index module is split in a bottom half and top half. The top half
contains generic code which hides the underlying storage implementation.
The bottom half implements the storage abstraction.
With this change, the bottom half is moved to coreboot, while the top half stays
in vboot_reference.
TEST=Built with USE=+/-vboot2 for Blaze. Built Samus, Link.

When the driver is included in bootblock, malloc() is not available.
Come to think of it, it is perfectly fine to use a statically

unlikely to require concurrent support of multiple SPI devices of the

The GCC 4.9.2 update showed that the boot_state_init_entry
structures were being padded and assumed to be aligned in to an
increased size. The bootstate scheduler for static entries,
boot_state_schedule_static_entries(), was then calculating the
wrong values within the array. To fix this just use a pointer to
the boot_state_init_entry structure that needs to be scheduled.
In addition to the previous issue noted above, the .bs_init
section was sitting in the read only portion of the image while
the fields within it need to be writable. Also, the
boot_state_schedule_static_entries() was using symbol comparison
to terminate a loop which in C can lead the compiler to always
evaluate the loop at least once since the language spec indicates
no 2 symbols can be the same value.

This improves readability significantly.
One of the changes is to remove in inline stub declaration of
(get|set)_option. Although that provided the ability for the compiler
to optimize out code when USE_OPTION_TABLE is not selected, there is
no evidence that such savings are measureable.

int do_smbus_write_byte(u32 smbus_io_base, u32 device, u32 address, u8 val)

The FSP uses a lot of UEFI HOB (Hand Off Block) functions for reporting
and passing information to coreboot. These seem to me like they should
be in their own file, so I'm splitting them out of fsp_util.c. I'll
be adding a couple more functions in the next patch.
These functions should all be compliant to the Hand Off Block spec.

This patch has a rather twisted history. It was originally split off
from a chromium patch, which moved ALTCENTURY to Kconfig. However,
since we have no user without ALTCENTURY, we've agreed that the best
way to proceed is to eliminate the non-ALTCENTURY case entirely.
The old commit message and identifiers are kept below for reference:
The availability of "ALTCENTURY" is now set through a kconfig
variable so it can be available to the RTC driver without having to have a
specialized interface.

Coreboot has all necessary infrastructure to use the proper SPI flash
interface in bootblock for CBFS. This patch creates a common CBFS
wrapper which can be enabled on different platforms as required.
COMMON_CBFS_SPI_WRAPPER, a new configuration option, enables the
common CBFS interface and prevents default inclusion of all SPI chip
drivers, only explicitly configured ones will be included when the new
feature is enabled. Since the wrapper uses the same driver at all
stages, enabling the new feature will also make it necessary to
include the SPI chip drivers in bootblock and romstage images.
init_default_cbfs_media() can now be common for different platforms,
and as such is defined in the library.

This consolidates all calls to spi_claim_bus() and spi_release_bus()
to a single location where spi_xfer() is called. This avoids confusing
(and potentially redundant) calls that were being done throughout the
generic spi_flash.c functions and chip-specific functions.
I don't think the current approach could even work since many chip
drivers assert /CS once and then issue multiple commands such as page
program followed by reading the status register. I suspect the reason
we didn't notice it on x86 is because the ICH/PCH handled each
individual command correctly (spi_claim_bus() and spi_release_bus()
are noops) in spite of the broken code.

This adds a wrapper function and a Kconfig variable to differentiate
between SPI controllers which use atomic cycle sequencing versus
those where the transaction sequence is controlled manually. Currently
this boils down to x86 vs. non-x86.
Yes, it's hideous. The current API only worked because, for better or
worse, x86 platforms have been homogeneous in this regard since they
started using SPI as an alternative to FWH for boot flash. Now that
we have non-x86 platforms which use general purpose SPI controllers,
we should overhaul the entire SPI infrastructure to be more adaptable.

This attempts to isolate/fix some x86-isms:
- Translate flash offset to memory-mapped address only on x86.
- Guard ACPI-dependent line of code
- Use a Kconfig variable for SPI bus when probing the flash rather
than assuming the bus is always on bus 0.
- Zero-out timestamp on non-x86 until we have a better abstraction.

This severs a dependency the eventlog code has on initializing
chipset/SoC SPI controller. Currently elog_init() calls spi_init()
as a catch-all. This worked for x86 since the SPI controller is only
used for one thing on existing platforms. As we add eventlogging
support to non-x86 platforms we need to consider the more generalized
case where the assumptions about how SPI works on x86 are no longer
valid.

The new API is in use in depthcharge and is based around the "i2c_transfer"
function instead of i2c_read and i2c_write. The new function takes an array of
i2c_seg structures which represent each portion of the transfer after a start
bit and before the stop bit. If there's more than one segment, they're
seperated by repeated starts.
Some wrapper functions have also been added which make certain common
operations easy. These include reading or writing a byte from a register or
reading or writing a blob of raw data. The i2c device drivers generally use
these wrappers but can call the i2c_transfer function directly if the need
something different.
The tegra i2c driver was very similar to the one in depthcharge and was simple
to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and
replace the ones in coreboot. The Exynos 5420 driver was ported from the high
speed portion of the one in coreboot and was straightforward to port back. The
low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot
and were replaced with the depthcharge implementation.

Depending on the platform the underlying regions vboot requires
may not be accessible through a memory-mapped interface. Allow
for non-memory-mapped regions by providing a region request
abstraction. There is then only a few touch points in the code to
provide compile-time decision making no how to obtain a region.
For the vblocks a temporary area is allocated from cbmem. They
are then read from the SPI into the temporarily buffer.

On entry to ramstage CBMEM is looked for a copy of an already initialized
EHCI debug dongle state. If a copy is found, it contained the state before
CAR migration and the USB protocol data toggle can be out of sync. It's an
even/odd kind of a parity check, so roughly every other build would
show the problem as invalid first line: 'ug found in CBMEM.'
After CAR migration, re-direct the state changes to correct CBMEM table.

Most of the code related to the mc146818 is not related to the RTC and is
really for managing the CMOS storage. Since we intend to add a generic API
for RTC drivers it's inconvenient for those functions to have an rtc_ prefix.
This CL renames those functions so they start with cmos_ instead. There are
some places where rtc_init was called with a comment that says something about
starting the RTC. That wasn't correct before (the RTC is always running), but
it looks a little odd now that the function is called cmos_init.
This CL also opportunistically cleans up some style problems in this file.

Support added for Micron N25Q128 SPI flash, which has
the same manufacturer id as ST Micro. Jedec ID =
0x20 0xBB 0x18. Since existing stmicro.c only compares
the last device id byte, this flash is mistakenly
identified as M25P128, which has ID = 0x20 0x20 0x18.
To handle this situation and avoid breaking code for
existing devices, a two byte .id member is added.
New devices should be added to the beginning of the
flash table array with .idcode = STM_ID_USE_ALT_ID and
.id = the two byte jedec device id.
A 4KB subsector erase capability is added and used for
this new device. It requires using a different SPI
op-code supported by adding .op_erase member. Previous
devices defined in stmicro.c are assigned their original
op-code for 64KB sector erase.
N25Q128 is now working on a custom designed Bayley Bay
based board. Tested by verifying the MRC fastboot cache
is successfully (re)written. Note that previous devices

The W25Q128FW spi part is programatically equivalent
to the other W25Q128 parts except it operates at 1.8V.
Just add a new entry with the appropriate ID.
Tested on a modified MinnowMax Board.

tegra124: implement x2 mode for SPI transfers on CBFS media
This implements x2 mode when reading CBFS media over SPI.
In theory this effectively doubles our throughput, though the initial
results were almost negligibly better. Using a logic analyzer we see
a pattern of 12 clocks, ~70ns delay, 4 clocks, ~310ns delay. So if we
want to see further gains here then we'll probably need to tune AHB
arbitration and utilization to eliminate bubbles/stalls when copying
from APB DMA.
