      Replace __ASSEMBLY__ with compiler-builtin __ASSEMBLER__ · d5dfdeb6
      Julius Werner authored 
      

NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__.

All common C compilers predefine a macro called __ASSEMBLER__ when
preprocessing a .S file. There is no reason for TF-A to define it's own
__ASSEMBLY__ macro for this purpose instead. To unify code with the
export headers (which use __ASSEMBLER__ to avoid one extra dependency),
let's deprecate __ASSEMBLY__ and switch the code base over to the
predefined standard.

Add support for multiple Cryptocell revisions which
use different APIs.

This commit only refactors the existing code in preperation to the addition
of another Cryptocell revisions later on.

      cryptocell: move Cryptocell specific API into driver · 36ec2bb0
      Gilad Ben-Yossef authored 
      

Code using Cryptocell specific APIs was used as part of the
arm common board ROT support, instead of being abstracted
in Cryptocell specific driver code, creating two problems:
- Any none arm board that uses Cryptocell wuld need to
  copy and paste the same code.
- Inability to cleanly support multiple versions of Cryptocell
  API and products.

Move over Cryptocell specific API calls into the Cryptocell
driver, creating abstraction API where needed.

      SMMUv3: Abort DMA transactions · 1461ad9f
      Alexei Fedorov authored 
      

For security DMA should be blocked at the SMMU by default
unless explicitly enabled for a device. SMMU is disabled
after reset with all streams bypassing the SMMU, and
abortion of all incoming transactions implements a default
deny policy on reset.
This patch also moves "bl1_platform_setup()" function from
arm_bl1_setup.c to FVP platforms' fvp_bl1_setup.c and
fvp_ve_bl1_setup.c files.

      SMMUv3: refactor the driver code · ccd4d475
      Alexei Fedorov authored 
      

This patch is a preparation for the subsequent changes in
SMMUv3 driver. It introduces a new "smmuv3_poll" function
and replaces inline functions for accessing SMMU registers
with mmio read/write operations. Also the infinite loop
for the poll has been replaced with a counter based timeout.

      Remove several warnings reported with W=1 · 609e053c
      Ambroise Vincent authored 
      

Improved support for W=1 compilation flag by solving missing-prototypes
and old-style-definition warnings.

The libraries are compiling with warnings (which turn into errors with
the Werror flag).

Outside of libraries, some warnings cannot be fixed without heavy
structural changes.

      ti: k3: common: Add support for runtime detection of GICR base address · b5443284
      Andrew F. Davis authored 
      

Valid addresses for GICR base are always a set calculable distance from
the GICD and is based on the number of cores a given instance of GICv3 IP
can support. The formula for the number of address bits is given by the
ARM GIC-500 TRM section 3.2 as 2^(18+log2(cores)) with the MSB set to
one for GICR instances. Holes in the GIC address space are also
guaranteed to safely return 0 on reads. This allows us to support runtime
detection of the GICR base address by starting from GIC base address plus
BIT(18) and walking until the GICR ID register (IIDR) is detected. We
stop searching after BIT(20) to prevent searching out into space if
something goes wrong. This can be extended out if we ever have a device
with 16 or more cores.

      Sanitise includes across codebase · 09d40e0e
      Antonio Nino Diaz authored 
      Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca339

 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

      GIC: Remove lowest priority constants · 35cd9e81
      Jeenu Viswambharan authored 
      

The GIC lowest priority values for each world depends on the number of
priority values implemented in hardware. These constants currently
defined in gic_common.h only meant to enumerate lowest possible
architectural values. Since these values are not used in generic code or
upstream platforms, and that general use of these constants can be
wrong, remove these. Platforms should either define and use these as
appropriate, or determine correct values at run time.

      Standardise header guards across codebase · c3cf06f1
      Antonio Nino Diaz authored 
      

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

      tzc: Fix MISRA defects · af6491f8
      Antonio Nino Diaz authored 
      

The definitions FAIL_CONTROL_*_SHIFT were incorrect, they have been
fixed.

The types tzc_region_attributes_t and tzc_action_t have been removed and
replaced by unsigned int because it is not allowed to do logical
operations on enums.

Also, fix some address definitions in arm_def.h.

      Emit warnings when using deprecated GIC init · dcf01a0a
      Dan Handley authored 
      

Emit runtime warnings when intializing the GIC drivers using the
deprecated method of defining integer interrupt arrays in the GIC driver
data structures; interrupt_prop_t arrays should be used instead. This
helps platforms detect that they have migration work to do. Previously,
no warning was emitted in this case. This affects both the GICv2 and GICv3
drivers.

Also use the __deprecated attribute to emit a build time warning if these
deprecated fields are used. These warnings are suppressed in the GIC
driver compatibility functions but will be visible if platforms use them.
