Introduce new bootmem tags to allow more fine grained control over buffer
allocation on various platforms. The new tags are:
BM_MEM_RAMSTAGE : Memory where any kind of boot firmware resides and that
should not be touched by bootmem (by example: stack,
TTB, program, ...).
BM_MEM_PAYLOAD : Memory where any kind of payload resides and that should
not be touched by bootmem.
Starting with this commit all bootmem methods will no longer see memory
that is used by coreboot as usable RAM.
Bootmem changes:
* Introduce a weak function to add platform specific memranges.
* Mark memory allocated by bootmem as BM_TAG_PAYLOAD.
* Assert on failures.
* Add _stack and _program as BM_MEM_RAMSTAGE.
ARMv7 and ARMv8 specific changes:
* Add _ttb and _postram_cbfs_cache as BM_MEM_RAMSTAGE.
ARMv7 specific changes:
* Add _ttb_subtables as BM_MEM_RAMSTAGE.

The ARMv8.4 RAS extensions introduce architectural support for software
to inject faults into the system in order to test fault-handling
software. This patch introduces the build option FAULT_HANDLING_SUPPORT
to allow for lower ELs to use registers in the Standard Error Record to
inject fault. The build option RAS_EXTENSIONS must also be enabled along
with fault injection.
This feature is intended for testing purposes only, and is advisable to
keep disabled for production images.

EHF currently allows for registering interrupt handlers for a defined
priority ranges. This is primarily targeted at various EL3 dispatchers
to own ranges of secure interrupt priorities in order to delegate
execution to lower ELs.
The RAS support added by earlier patches necessitates registering
handlers based on interrupt number so that error handling agents shall
receive and handle specific Error Recovery or Fault Handling interrupts
at EL3.
This patch introduces a macro, RAS_INTERRUPTS() to declare an array of
interrupt numbers and handlers. Error handling agents can use this macro
to register handlers for individual RAS interrupts. The array is
expected to be sorted in the increasing order of interrupt numbers.
As part of RAS initialisation, the list of all RAS interrupts are sorted
based on their ID so that, given an interrupt, its handler can be looked
up with a simple binary search.
For an error handling agent that wants to handle a RAS interrupt,
platform must:
- Define PLAT_RAS_PRI to be the priority of all RAS exceptions.
- Enumerate interrupts to have the GIC driver program individual EL3
interrupts to the required priority range. This is required by EHF
even before this patch.
Documentation to follow.

Previous patches added frameworks for handling RAS errors. This patch
introduces features that the platform can use to enumerate and iterate
RAS nodes:
- The REGISTER_RAS_NODES() can be used to expose an array of
ras_node_info_t structures. Each ras_node_info_t describes a RAS
node, along with handlers for probing the node for error, and if
did record an error, another handler to handle it.
- The macro for_each_ras_node() can be used to iterate over the
registered RAS nodes, probe for, and handle any errors.
The common platform EA handler has been amended using error handling
primitives introduced by both this and previous patches.

The ARMv8 RAS Extensions introduced Standard Error Records which are a
set of standard registers through which:
- Platform can configure RAS node policy; e.g., notification
mechanism;
- RAS nodes can record and expose error information for error handling
agents.
Standard Error Records can either be accessed via. memory-mapped
or System registers. This patch adds helper functions to access
registers and fields within an error record.

RAS extensions are mandatory for ARMv8.2 CPUs, but are also optional
extensions to base ARMv8.0 architecture.
This patch adds build system support to enable RAS features in ARM
Trusted Firmware. A boolean build option RAS_EXTENSION is introduced for
this.
With RAS_EXTENSION, an Exception Synchronization Barrier (ESB) is
inserted at all EL3 vector entry and exit. ESBs will synchronize pending
external aborts before entering EL3, and therefore will contain and
attribute errors to lower EL execution. Any errors thus synchronized are
detected via. DISR_EL1 register.
When RAS_EXTENSION is set to 1, HANDLE_EL3_EA_FIRST must also be set to 1.

At present, any External Abort routed to EL3 is reported as an unhandled
exception and cause a panic. This patch enables ARM Trusted Firmware to
handle External Aborts routed to EL3.
With this patch, when an External Abort is received at EL3, its handling
is delegated to plat_ea_handler() function. Platforms can provide their
own implementation of this function. This patch adds a weak definition
of the said function that prints out a message and just panics.
In order to support handling External Aborts at EL3, the build option
HANDLE_EA_EL3_FIRST must be set to 1.
Before this patch, HANDLE_EA_EL3_FIRST wasn't passed down to
compilation; this patch fixes that too.

ifdtool has relied on one of the fields within FCBA(read_freq) to
determine whether a platform supports IFD_VERSION_1 or
IFD_VERSION_2. However, newer platforms like GLK and CNL do not have
read_freq field in FCBA and so the value of these bits cannot be used
as an indicator to distinguish IFD versions. In the long run, we need
to re-write ifdtool to have a better mapping of SoC to IFD fields. But
until that is done, this change adds a list of platforms that we know
do not support read_freq field but still use IFD_VERSION_2. This
change also updates GLK and CNL to pass in platform parameter to
