      Introduce object pool allocator · 9cc4651c
      Sandrine Bailleux authored 
      

The object pool allocator provides a simplistic interface to manage
allocation in a fixed-size static array. The caller creates a static
"object pool" out of such an array and may then call pool_alloc() to
get the next available object within the pool. There is also a variant
to get multiple consecutive objects: pool_alloc_n().

Note that this interface does not provide any way to free the objects
afterwards. This is by design and it is not a limitation. We do not
want to introduce complexity induced by memory freeing, such as
use-after-free bugs, memory fragmentation and so on.

      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.

      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.

      Introduce RECLAIM_INIT_CODE build flag · 1dcc28cf
      Daniel Boulby authored 
      

This patch introduces a build flag "RECLAIM_INIT_CODE" to mark boot time
code which allows platforms to place this memory in an appropriate
section to be reclaimed later. This features is primarily targeted for
BL31. Appropriate documentation updates are also done.

      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.

      Readjust BL2 size after sharing Mbed TLS heap · 2dac2c0b
      John Tsichritzis authored 
      

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.
