No need for these wrapper functions anymore. The compiler-rt builtins
provide runtime support for 64-bit division and modulo operations.

Add support for firmware upgrade on AArch32.
This patch has been tested on the FVP models.
NOTE: Firmware upgrade on Juno AArch32 is not currently supported.

This patch adds `TRUSTED_BOARD_BOOT` support for AArch32 mode.
To build this patch the "mbedtls/include/mbedtls/bignum.h"
needs to be modified to remove `#define MBEDTLS_HAVE_UDBL`
when `MBEDTLS_HAVE_INT32` is defined. This is a workaround
for "https://github.com/ARMmbed/mbedtls/issues/708"
NOTE: TBBR support on Juno AArch32 is not currently supported.

Minor fixes to the xlat tables lib v2

A previous patch superseded the MBEDTLS_KEY_ALG. This patch updates
the ARM platforms to use the new TF_MBEDTLS_KEY_ALG define.

This patch renames MBEDTLS_KEY_ALG to TF_MBEDTLS_KEY_ALG. This
completes the migration of TF specific macros so that they do not
have the MBEDTLS_ suffix (see arm-trusted-firmware#874).

An earlier patch (arm-trusted-firmware#874) migrated MBEDTLS_ suffixed
macros to have a TBBR_ suffix to avoid any potential clash with future
mbedtls macros.
But on reflection the TBBR_ suffix could be confusing as the macros
are used to drive TF-specific configuration of mbedtls. As such
this patch migrates these macros from TBBR_suffix to TF_MBEDTLS_
suffix which more accurately conveys their use.

The current SMC context data structure `smc_ctx_t` and related helpers are
optimized for case when SMC call does not result in world switch. This was
the case for SP_MIN and BL1 cold boot flow. But the firmware update usecase
requires world switch as a result of SMC and the current SMC context helpers
were not helping very much in this regard. Therefore this patch does the
following changes to improve this:
1. Add monitor stack pointer, `spmon` to `smc_ctx_t`
The C Runtime stack pointer in monitor mode, `sp_mon` is added to the
SMC context, and the `smc_ctx_t` pointer is cached in `sp_mon` prior
to exit from Monitor mode. This makes is easier to retrieve the
context when the next SMC call happens. As a result of this change,
the SMC context helpers no longer depend on the stack to save and
restore the register.
This aligns it with the context save and restore mechanism in AArch64.
2. Add SCR in `smc_ctx_t`
Adding the SCR register to `smc_ctx_t` makes it easier to manage this
register state when switching between non secure and secure world as a
result of an SMC call.

Migrate secure payload dispatchers to new SMC terminology
|
|
AEMv8-A Model release v8.4 has been made available and Trusted Firmware
has been tested against these versions as part of its CI system. This
patch updates the user guide documentation to reflect the version of AEM
and Cortex Models that Trusted Firmware has been tested against.
Additionally, ARM FVPs FVP_Base_Cortex-A57x1-A53x1 and
FVP_Base_Cortex-A57x2-A53x4 are removed from the list of tested FVPs
as they are currently not being tested with the latest version of ARM
Trusted Firmware.
Also, documentation and links to Linaro pages have been updated to
reflect the changes in the ARM community document hosting.

Fix execute-never permissions in xlat tables libs

Since Issue B (November 2016) of the SMC Calling Convention document
standard SMC calls are renamed to yielding SMC calls to help avoid
confusion with the standard service SMC range, which remains unchanged.
http://infocenter.arm.com/help/topic/com.arm.doc.den0028b/ARM_DEN0028B_SMC_Calling_Convention.pd
A previous patch introduced a new define for yielding SMC call type.
This patch updates the secure payload dispatchers (except the TSPD) to
use this new define and also migrates the code to use the new
terminology.

In AArch64, privileged exception levels control the execution state
(a.k.a. register width) of the immediate lower Exception Level; i.e.
whether the lower exception level executes in AArch64 or AArch32 state.
For an exception level to have its execution state changed at run time,
it must request the change by raising a synchronous exception to the
higher exception level.
This patch implements and adds such a provision to the ARM SiP service,
by which an immediate lower exception level can request to switch its
execution state. The execution state is switched if the request is:
- raised from non-secure world;
- raised on the primary CPU, before any secondaries are brought online
with CPU_ON PSCI call;
- raised from an exception level immediately below EL3: EL2, if
implemented; otherwise NS EL1.
If successful, the SMC doesn't return to the caller, but to the entry
point supplied with the call. Otherwise, the caller will observe the SMC
returning with STATE_SW_E_DENIED code. If ARM Trusted Firmware is built
for AArch32, the feature is not supported, and the call will always
fail.
For the ARM SiP service:
- Add SMC function IDs for both AArch32 and AArch64;
- Increment the SiP service minor version to 2;
- Adjust the number of supported SiP service calls.
Add documentation for ARM SiP service.

Some recent changes have added direct use of the echo command without

parameters reports the mode ("ECHO is on").
This is corrected using the ECHO_BLANK_LINE macro already provided

2 problems were found, but are in one change to avoid submitting a patch
that might fail to build. The problems were:
1. The macro MAKE_PREREQ_DIR has a minor bug, in that it is capable of
generating recursive dependencies.
2. The inclusion of BUILD_DIR in TEMP_OBJ_DIRS left no explicit
dependency, BUILD_DIR might not exist when subdirectories are
created by a thread on another CPU.
This fix corrects these with the following changes:
1. MAKE_PREREQ_DIR does nothing for a direct self dependency.
2. BUILD_DIR is built using MAKE_PREREQ_DIR.
3. BUILD_DIR is an explicit prerequisite of all OBJ_DIRS.

Translation regimes that only support one virtual address space (such as
the ones for EL2 and EL3) can flag memory regions as execute-never by
setting to 1 the XN bit in the Upper Attributes field in the translation
tables descriptors. Translation regimes that support two different
virtual address spaces (such as the one shared by EL1 and EL0) use bits
PXN and UXN instead.
The Trusted Firmware runs at EL3 and EL1, it has to handle translation
tables of both translation regimes, but the previous code handled both
regimes the same way, as if both had only 1 VA range.
When trying to set a descriptor as execute-never it would set the XN
bit correctly in EL3, but it would set the XN bit in EL1 as well. XN is
at the same bit position as UXN, which means that EL0 was being
prevented from executing code at this region, not EL1 as the code
intended. Therefore, the PXN bit was unset to 0 all the time. The result
is that, in AArch64 mode, read-only data sections of BL2 weren't
protected from being executed.
This patch adds support of translation regimes with two virtual address
spaces to both versions of the translation tables library, fixing the
execute-never permissions for translation tables in EL1.
The library currently does not support initializing translation tables
for EL0 software, therefore it does not set/unset the UXN bit. If EL1
software needs to initialize translation tables for EL0 software, it
should use a different library instead.

xlat lib: Don't set mmap_attr_t enum to be -1
|
|
-1 is not a defined mmap_attr_t type. Instead of using invalid enum
types, we can either choose to define a INVALID type OR handle the
condition specifically.
Since the usage of mmap_region_attr is limited, it is easier to just
handle the error condition specifically and return 0 or -1 depending
on success or fail.

The video memory carveout has to be re-sized depending on the Video
content. This requires the NS world to send us new base/size values.
Before setting up the new region, we must zero out the previous memory
region, so that the video frames are not leaked to the outside world.
This patch adds the logic to zero out the previous memory carveout
region.

utils.h is included in various header files for the defines in it.
Some of the other header files only contain defines. This allows the
header files to be shared between host and target builds for shared defines.
Recently types.h has been included in utils.h as well as some function
prototypes.
Because of the inclusion of types.h conflicts exist building host tools
abd these header files now. To solve this problem,
move the defines to utils_def.h and have this included by utils.h and
change header files to only include utils_def.h and not pick up the new
types.h being introduced.
