Soby Mathew e60f2af949 ARM plat changes to enable CryptoCell integration
This patch makes the necessary changes to enable ARM platform to
successfully integrate CryptoCell during Trusted Board Boot. The
changes are as follows:

* A new build option `ARM_CRYPTOCELL_INTEG` is introduced to select
  the CryptoCell crypto driver for Trusted Board boot.

* The TrustZone filter settings for Non Secure DRAM is modified
  to allow CryptoCell to read this memory. This is required to
  authenticate BL33 which is loaded into the Non Secure DDR.

* The CSS platforms are modified to use coherent stacks in BL1 and BL2
  when CryptoCell crypto is selected. This is because CryptoCell makes
  use of DMA to transfer data and the CryptoCell SBROM library allocates
  buffers on the stack during signature/hash verification.

Masahiro Yamada 3d8256b2a1 Use #ifdef for IMAGE_BL* instead of #if
One nasty part of ATF is some of boolean macros are always defined
as 1 or 0, and the rest of them are only defined under certain
conditions.

For the former group, "#if FOO" or "#if !FOO" must be used because
"#ifdef FOO" is always true.  (Options passed by $(call add_define,)
are the cases.)

For the latter, "#ifdef FOO" or "#ifndef FOO" should be used because
checking the value of an undefined macro is strange.

Here, IMAGE_BL* is handled by make_helpers/build_macro.mk like
follows:

  $(eval IMAGE := IMAGE_BL$(call uppercase,$(3)))

  $(OBJ): $(2)
          @echo "  CC      $$<"
          $$(Q)$$(CC) $$(TF_CFLAGS) $$(CFLAGS) -D$(IMAGE) -c $$< -o $$@

This means, IMAGE_BL* is defined when building the corresponding
image, but *undefined* for the other images.

So, IMAGE_BL* belongs to the latter group where we should use #ifdef
or #ifndef.

Yatharth Kochar a8aa7fec1d ARM platform changes for new version of image loading
This patch adds changes in ARM platform code to use new
version of image loading.

Following are the major changes:
  -Refactor the signatures for bl31_early_platform_setup()
   and arm_bl31_early_platform_setup() function to use
   `void *` instead of `bl31_params_t *`.
  -Introduce `plat_arm_bl2_handle_scp_bl2()` to handle
   loading of SCP_BL2 image from BL2.
  -Remove usage of reserve_mem() function from
   `arm_bl1_early_platform_setup()`
  -Extract BL32 & BL33 entrypoint info, from the link list
   passed by BL2, in `arm_bl31_early_platform_setup()`
  -Provides weak definitions for following platform functions:
     plat_get_bl_image_load_info
     plat_get_next_bl_params
     plat_flush_next_bl_params
     bl2_plat_handle_post_image_load
  -Instantiates a descriptor array for ARM platforms
   describing image and entrypoint information for
   `SCP_BL2`, `BL31`, `BL32` and `BL33` images.

All the above changes are conditionally compiled using the
`LOAD_IMAGE_V2` flag.

Antonio Nino Diaz 0289970d6c ARM platforms: Define common image sizes
Compile option `ARM_BOARD_OPTIMISE_MMAP` has been renamed to
`ARM_BOARD_OPTIMISE_MEM` because it now applies not only to defines
related to the translation tables but to the image size as well.

The defines `PLAT_ARM_MAX_BL1_RW_SIZE`, `PLAT_ARM_MAX_BL2_SIZE` and
`PLAT_ARM_MAX_BL31_SIZE` have been moved to the file board_arm_def.h.
This way, ARM platforms no longer have to set their own values if
`ARM_BOARD_OPTIMISE_MEM=0` and they can specify optimized values
otherwise. The common sizes have been set to the highest values used
for any of the current build configurations.

This is needed because in some build configurations some images are
running out of space. This way there is a common set of values known
to work for all of them and it can be optimized for each particular
platform if needed.

The space reserved for BL2 when `TRUSTED_BOARD_BOOT=0` has been
increased. This is needed because when memory optimisations are
disabled the values for Juno of `PLAT_ARM_MMAP_ENTRIES` and
`MAX_XLAT_TABLES` are higher. If in this situation the code is
compiled in debug mode and with "-O0", the code won't fit.

Rationalise MMU and Page table related constants on ARM platforms
2016-02-22 13:23:49 +00:00
Vikram Kanigiri c64a04486f Rationalise MMU and Page table related constants on ARM platforms
`board_arm_def.h` contains multiple definitions of
`PLAT_ARM_MMAP_ENTRIES` and `MAX_XLAT_TABLES` that are optimised for
memory usage depending upon the chosen build configuration. To ease
maintenance of these constants, this patch replaces their multiple
definitions with a single set of definitions that will work on all ARM
platforms.

Platforms can override the defaults with optimal values by enabling the
`ARM_BOARD_OPTIMISE_MMAP` build option. An example has been provided in
the Juno ADP port.

Additionally, `PLAT_ARM_MMAP_ENTRIES` is increased by one to accomodate
future ARM platforms.

Soby Mathew 0108047ae4 Allow multi cluster topology definitions for ARM platforms
The common topology description helper funtions and macros for
ARM Standard platforms assumed a dual cluster system. This is not
flexible enough to scale to multi cluster platforms. This patch does
the following changes for more flexibility in defining topology:

1. The `plat_get_power_domain_tree_desc()` definition is moved from
   `arm_topology.c` to platform specific files, that is `fvp_topology.c`
   and `juno_topology.c`. Similarly the common definition of the porting
   macro `PLATFORM_CORE_COUNT` in `arm_def.h` is moved to platform
   specific `platform_def.h` header.

2. The ARM common layer porting macros which were dual cluster specific
   are now removed and a new macro PLAT_ARM_CLUSTER_COUNT is introduced
   which must be defined by each ARM standard platform.

3. A new mandatory ARM common layer porting API
   `plat_arm_get_cluster_core_count()` is introduced to enable the common
   implementation of `arm_check_mpidr()` to validate MPIDR.

4. For the FVP platforms, a new build option `FVP_NUM_CLUSTERS` has been
   introduced which allows the user to specify the cluster count to be
   used to build the topology tree within Trusted Firmare. This enables
   Trusted Firmware to be built for multi cluster FVP models.

Current code assumes `SCP_COM_SHARED_MEM_BASE` as the base address
for BOM/SCPI protocol between AP<->SCP on all CSS platforms. To
cater for future ARM platforms this is made platform specific.
Similarly, the bit shifts of `SCP_BOOT_CONFIG_ADDR` are also made
platform specific.

Vikram Kanigiri ecf70f7bdb Re-factor definition of some macros on ARM platforms
This patch moves the definition of some macros used only on
ARM platforms from common headers to platform specific headers.
It also forces all ARM standard platforms to have distinct
definitions (even if they are usually the same).
 1. `PLAT_ARM_TZC_BASE` and `PLAT_ARM_NSTIMER_FRAME_ID` have been
     moved from `css_def.h` to `platform_def.h`.
 2. `MHU_BASE` used in CSS platforms is moved from common css_def.h
    to platform specific header `platform_def.h` on Juno and
    renamed as `PLAT_ARM_MHU_BASE`.
 3. To cater for different sizes of BL images, new macros like
    `PLAT_ARM_MAX_BL31_SIZE` have been created for each BL image. All
    ARM platforms need to define them for each image.

Achin Gupta 27573c59a6 Rework use of ARM GIC drivers on ARM platforms
Suport for ARM GIC v2.0 and v3.0 drivers has been reworked to create three
separate drivers instead of providing a single driver that can work on both
versions of the GIC architecture. These drivers correspond to the following
software use cases:

1. A GICv2 only driver that can run only on ARM GIC v2.0 implementations
   e.g. GIC-400

2. A GICv3 only driver that can run only on ARM GIC v3.0 implementations
   e.g. GIC-500 in a mode where all interrupt regimes use GICv3 features

3. A deprecated GICv3 driver that operates in legacy mode. This driver can
   operate only in the GICv2 mode in the secure world. On a GICv3 system, this
   driver allows normal world to run in either GICv3 mode (asymmetric mode)
   or in the GICv2 mode. Both modes of operation are deprecated on GICv3
   systems.

ARM platforms implement both versions of the GIC architecture. This patch adds a
layer of abstraction to help ARM platform ports chose the right GIC driver and
corresponding platform support. This is as described below:

1. A set of ARM common functions have been introduced to initialise the GIC and
   the driver during cold and warm boot. These functions are prefixed as
   "plat_arm_gic_". Weak definitions of these functions have been provided for
   each type of driver.

2. Each platform includes the sources that implement the right functions
   directly into the its makefile. The FVP can be instantiated with different
   versions of the GIC architecture. It uses the FVP_USE_GIC_DRIVER build option
   to specify which of the three drivers should be included in the build.

3. A list of secure interrupts has to be provided to initialise each of the
  three GIC drivers. For GIC v3.0 the interrupt ids have to be further
  categorised as Group 0 and Group 1 Secure interrupts. For GIC v2.0, the two
  types are merged and treated as Group 0 interrupts.

  The two lists of interrupts are exported from the platform_def.h. The lists
  are constructed by adding a list of board specific interrupt ids to a list of
  ids common to all ARM platforms and Compute sub-systems.

This patch also makes some fields of `arm_config` data structure in FVP redundant
and these unused fields are removed.

Soby Mathew 5f3a60301e CSS: Implement topology support for System power domain
This patch implements the necessary topology changes for supporting
system power domain on CSS platforms. The definition of PLAT_MAX_PWR_LVL and
PLAT_NUM_PWR_DOMAINS macros are removed from arm_def.h and are made platform
specific. In addition, the `arm_power_domain_tree_desc[]` and
`arm_pm_idle_states[]` are modified to support the system power domain
at level 2. With this patch, even though the power management operations
involving the system power domain will not return any error, the platform
layer will silently ignore any operations to the power domain. The actual
power management support for the system power domain will be added later.
