      Remove sp_min functions from plat_common.c · 0ed8c001
      Soby Mathew authored 
      

This patch removes default platform implementations of sp_min
platform APIs from plat/common/aarch32/plat_common.c. The APIs
are now implemented in `plat_sp_min_common.c` file within the
same folder.

The ARM platform layer had a weak definition of sp_min_platform_setup2()
which conflicted with the weak definition in the common file. Hence this
patch fixes that by introducing a `plat_arm_` version of the API thus
allowing individual boards within ARM platforms to override it if they
wish to.

Fixes ARM-software/tf-issues#559

      Suppress spurious deprecated declaration warnings · 97924e45
      Dan Handley authored 
      

Some generic compatibility functions emit deprecated declaration warnings
even when platforms do not use the deprecated functions directly. This
can be confusing. Suppress these warnings by using:
`#pragma GCC diagnostic ignored "-Wdeprecated-declarations"`

Also emit a runtime warning if the weak plat/common implemntation of
plat_get_syscnt_freq2() is used, as this implies the platform has not
migrated from plat_get_syscnt_freq(). The deprecated  declaration warnings
only help detect when platforms are calling deprecated functions, not when
they are defining deprecated functions.

Fixes ARM-software/tf-issues#550

      BL1: Deprecate the `bl1_init_bl2_mem_layout()` API · 101d01e2
      Soby Mathew authored 
      

The `bl1_init_bl2_mem_layout()` API is now deprecated. The default weak
implementation of `bl1_plat_handle_post_image_load()` calculates the
BL2 memory layout and populates the same in x1(r1). This ensures
compatibility for the deprecated API.

      Introduce the new BL handover interface · a6f340fe
      Soby Mathew authored 
      

This patch introduces a new BL handover interface. It essentially allows
passing 4 arguments between the different BL stages. Effort has been made
so as to be compatible with the previous handover interface. The previous
blx_early_platform_setup() platform API is now deprecated and the new
blx_early_platform_setup2() variant is introduced. The weak compatiblity
implementation for the new API is done in the `plat_bl_common.c` file.
Some of the new arguments in the new API will be reserved for generic
code use when dynamic configuration support is implemented. Otherwise
the other registers are available for platform use.

      Add image_id to bl1_plat_handle_post/pre_image_load() · 566034fc
      Soby Mathew authored 
      

This patch adds an argument to bl1_plat_post/pre_image_load() APIs
to make it more future proof. The default implementation of
these are moved to `plat_bl1_common.c` file.

These APIs are now invoked appropriately in the FWU code path prior
to or post image loading by BL1 and are not restricted
to LOAD_IMAGE_V2.

The patch also reorganizes some common platform files. The previous
`plat_bl2_el3_common.c` and `platform_helpers_default.c` files are
merged into a new `plat_bl_common.c` file.

NOTE: The addition of an argument to the above mentioned platform APIs
is not expected to have a great impact because these APIs were only
recently added and are unlikely to be used.

      qemu: Fix interrupt type check · 53a98be3
      Santeri Salko authored 
      

Function plat_ic_get_pending_interrupt_type() should return interrupt
type, not id. The function is used in aarch64 exception handling and
currently the irq/fiq forwarding fails if a secure interrupt happens while
running normal world.

The qemu-specific gic file does not contain any extra functionality so it
can be removed and common file can be used instead.

      Add default crash console code to hook up to new console API · 17cd67d2
      Julius Werner authored 
      

This patch expands the weak stubs for the plat_crash_console_xxx
functions in common platform code to use the new console API for crash
output. This should make crash console output "just work" for most cases
without the need for the platform to explicitly set up a crash console.
For cases where the normal console framework doesn't work (e.g. very
early crashes, before the platform can register any consoles), platforms
are still able to override the functions just like before.

This feature requires the MULTI_CONSOLE_API compile-time flag to work.
For builds which don't have it set, this patch has no practical effect.

      bl2-el3: Add BL2_EL3 image · b1d27b48
      Roberto Vargas authored 
      

This patch enables BL2 to execute at the highest exception level
without any dependancy on TF BL1. This enables platforms which already
have a non-TF Boot ROM to directly load and execute BL2 and subsequent BL
stages without need for BL1.  This is not currently possible because
BL2 executes at S-EL1 and cannot jump straight to EL3.

      Add new function-pointer-based console API · 9536bae6
      Julius Werner authored 
      

This patch overhauls the console API to allow for multiple console
instances of different drivers that are active at the same time. Instead
of binding to well-known function names (like console_core_init),
consoles now provide a register function (e.g. console_16550_register())
that will hook them into the list of active consoles. All console
operations will be dispatched to all consoles currently in the list.

The new API will be selected by the build-time option MULTI_CONSOLE_API,
which defaults to ${ERROR_DEPRECATED} for now. The old console API code
will be retained to stay backwards-compatible to older platforms, but
should no longer be used for any newly added platforms and can hopefully
be removed at some point in the future.

The new console API is intended to be used for both normal (bootup) and
crash use cases, freeing platforms of the need to set up the crash
console separately. Consoles can be individually configured to be active
active at boot (until first handoff to EL2), at runtime (after first
handoff to EL2), and/or after a crash. Console drivers should set a sane
default upon registration that can be overridden with the
console_set_scope() call. Code to hook up the crash reporting mechanism
to this framework will be added with a later patch.

This patch only affects AArch64, but the new API could easily be ported
to AArch32 as well if desired.

      Fix PSCI STAT time stamp collection · bfc87a8d
      Soby Mathew authored 
      

This patch includes various fixes for PSCI STAT functionality
relating to timestamp collection:

1. The PSCI stat accounting for retention states for higher level
power domains were done outside the locks which could lead to
spurious values in some race conditions. This is moved inside
the locks. Also, the call to start the stat accounting was redundant
which is now removed.

2. The timestamp wrap-around case when calculating residency did
not cater for AArch32. This is now fixed.

3. In the warm boot path, `plat_psci_stat_accounting_stop()` was
getting invoked prior to population of target power states. This
is now corrected.

      Implement log framework · 7f56e9a3
      Soby Mathew authored 
      

This patch gives users control over logging messages printed from the C
code using the LOG macros defined in debug.h Users now have the ability
to reduce the log_level at run time using the tf_log_set_max_level()
function. The default prefix string can be defined by platform by
overriding the `plat_log_get_prefix()` platform API which is also
introduced in this patch.

The new log framework results in saving of some RO data. For example,
when BL1 is built for FVP with LOG_LEVEL=LOG_LEVEL_VERBOSE, resulted
in saving 384 bytes of RO data and increase of 8 bytes of RW data. The
framework also adds about 108 bytes of code to the release build of FVP.

Fixes ARM-software/tf-issues#462

      cert: move platform_oid.h to include/tools_share for all platforms · bb41eb7a
      Masahiro Yamada authored 
      

Platforms aligned with TBBR are supposed to use their own OIDs, but
defining the same macros with different OIDs does not provide any
value (at least technically).

For easier use of TBBR, this commit allows platforms to reuse the OIDs
obtained by ARM Ltd.  This will be useful for non-ARM vendors that
do not need their own extension fields in their certificate files.

The OIDs of ARM Ltd. have been moved to include/tools_share/tbbr_oid.h

Platforms can include <tbbr_oid.h> instead of <platform_oid.h> by
defining USE_TBBR_DEFS as 1.  USE_TBBR_DEFS is 0 by default to keep the
backward compatibility.

For clarification, I inserted a blank line between headers from the
include/ directory (#include <...>) and ones from a local directory
(#include "..." ).

      Remove build option `ASM_ASSERTION` · 044bb2fa
      Antonio Nino Diaz authored 
      

The build option `ENABLE_ASSERTIONS` should be used instead. That way
both C and ASM assertions can be enabled or disabled together.

All occurrences of `ASM_ASSERTION` in common code and ARM platforms have
been replaced by `ENABLE_ASSERTIONS`.

ASM_ASSERTION has been removed from the user guide.
