      plat/arm/common: add an additional platform power level · 0e27faf4
      Chandni Cherukuri authored 
      

For platforms using multi-threaded CPUs, there can be upto four
platform power domain levels. At present, there are three platform
power domain levels that are defined for the CSS platforms. Define a
fourth level 'ARM_PWR_LVL3' as well to provide support for an
additional platform power domain level.

      plat/css: allow platforms to define the system power domain level · eff2f444
      Chandni Cherukuri authored 
      

The CSS_SYSTEM_PWR_DMN_LVL macro that defines the system power domain
level is fixed at ARM_PWR_LVL2 for all CSS platforms. However, the
system power domain level can be different for CSS platforms that
use multi-threaded CPUs.

So, in preparation towards adding support for platforms that use
multi-threaded CPUs, refactor the definition of CSS_SYSTEM_PWR_DMN_LVL
such that CSS_SYSTEM_PWR_DMN_LVL is uniquely defined for each of the
CSS platform.

      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

      Arm platforms: Fix DRAM address macros · 3d449de0
      Sandrine Bailleux authored 
      

On AArch32, ARM_DRAM1_BASE and ARM_DRAM1_SIZE constants are currently
32-bit values (because they are suffixed with UL and the value
0x80000000 fits in a unsigned long int, i.e. a 32-bit value). When
summing them up, the result overflows the maximum value that can be
encoded in a 32-bit value so it wraps around and does not result in
the expected value.

This patch changes the suffix of these constants into ULL so that they
always are 64-bit values.

      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.

      plat/arm: Remove file arm_board_def.h · 0f58d4f2
      Antonio Nino Diaz authored 
      

This file is shared between FVP and all CSS platforms. While it may be
true that some definitions can be common, it doesn't make sense
conceptually. For example, the stack size depends on the platform and so
does the SRAM size.

After removing them, there are not enough common definitions to justify
having this header, so the other definitions have been moved to the
platform_def.h of FVP, board_css_def.h and arm_def.h.

      plat/arm: Move norflash driver to drivers/ folder · aa7877c4
      Antonio Nino Diaz authored 
      

This way it can be reused by other platforms if needed.

Note that this driver is designed to work with the Versatile Express NOR
flash of Juno and FVP. In said platforms, the memory is organized as an
interleaved memory of two chips with a 16 bit word.

Any platform that wishes to reuse it with a different configuration will
need to modify the driver so that it is more generic.

      FVP: Reclaim init code for the stack · cb4adb0d
      Daniel Boulby authored 
      

Map the initialization code for BL31 to overlap with the memory
required for the secondary cores stack. Once BL31 has been
initialized the memory can be remapped to RW data so that it can
be used for secondary cores stacks. By moving code from .text to
.text.init the size of the BL31 image is decreased by a page.

Split arm_common.ld.S into two linker scripts, one for tzc_dram
(arm_tzc_dram.ld.S) and one for reclaiming initialization code
(arm_reclaim_init.ld.S) so that platforms can chose which memory
regions they wish to include.

      plat/arm: Remove option ARM_BOARD_OPTIMISE_MEM · c0740e4f
      Antonio Nino Diaz authored 
      

This option makes it hard to optimize the memory definitions of all Arm
platforms because any change in the common defines must work in all of
them. The best thing to do is to remove it and move the definition to
each platform's header.

FVP, SGI and SGM were using the definitions in board_arm_def.h. The
definitions have been copied to each platform's platform_def.h. Juno
was already using the ones in platform_def.h, so there have been no
changes.

      juno: Revert FWU update detect mechanism · 4da6f6cd
      Sathees Balya authored 
      The patch 7b56928a

 unified the FWU mechanism on FVP and Juno
platforms due to issues with MCC firmware not preserving the
NVFLAGS. With MCCv150 firmware, this issue is resolved. Also
writing to the NOR flash while executing from the same flash
in Bypass mode had some stability issues. Hence, since the
MCC firmware issue is resolved, this patch reverts to the
NVFLAGS mechanism to detect FWU. Also, with the introduction
of SDS (Shared Data Structure) by the SCP, the reset syndrome
needs to queried from the appropriate SDS field.

After introducing the Mbed TLS shared heap optimisation, reducing BL2
size by 3 pages didn't leave enough space for growth. We give 1 page
back to maximum BL2 size.

      Reduce BL2 size for FVP · 37574c56

This patch reduces BL2 size by 12kB. Thanks to the shared Mbed TLS heap
between BL1 and BL2, BL2 now requires less memory since it doesn't need
to allocate a heap anymore.

      Support shared Mbed TLS heap for FVP · ba597da7
      John Tsichritzis authored 
      

This patch introduces the shared Mbed TLS heap optimisation for Arm
platforms. The objective is the Mbed TLS heap to be shared between BL1
and BL2 so as to not allocate the heap memory twice. To achieve that,
the patch introduces all the necessary helpers for implementing this
optimisation. It also applies it for FVP.

      Prepare Mbed TLS drivers for shared heap · 6d01a463
      John Tsichritzis authored 
      

The Mbed TLS drivers, in order to work, need a heap for internal usage.
This heap, instead of being directly referenced by the drivers, now it
is being accessed indirectly through a pointer. Also, the heap, instead
of being part of the drivers, now it is being received through the
plat_get_mbedtls_heap() function. This function requests a heap from the
current BL image which utilises the Mbed TLS drivers.

Those changes create the opportunity for the Mbed TLS heap to be shared
among different images, thus saving memory. A default heap
implementation is provided but it can be overridden by a platform
specific, optimised implemenetation.
