      Enable ARMv8.6-ECV Self-Synch when booting to EL2 · 29d0ee54
      Jimmy Brisson authored 
      

Enhanced Counter Virtualization, ECV, is an architecture extension introduced
in ARMv8.6. This extension allows the hypervisor, at EL2, to setup
self-synchronizing views of the timers for it's EL1 Guests. This patch pokes the
control register to enable this extension when booting a hypervisor at EL2.

      Enable ARMv8.6-FGT when booting to EL2 · 110ee433
      Jimmy Brisson authored 
      

The Fine Grained Traps (FGT) architecture extension was added to aarch64 in
ARMv8.6. This extension primarily allows hypervisors, at EL2, to trap specific
instructions in a more fine grained manner, with an enable bit for each
instruction. This patch adds support for this extension by enabling the
extension when booting an hypervisor at EL2.

      xlat_tables_v2: add base table section name parameter for spm_mm · 0922e481
      Masahisa Kojima authored 
      Core spm_mm code expects the translation tables are located in the
inner & outer WBWA & shareable memory.
REGISTER_XLAT_CONTEXT2 macro is used to specify the translation
table section in spm_mm.

In the commit 363830df

 (xlat_tables_v2: merge
REGISTER_XLAT_CONTEXT_{FULL_SPEC,RO_BASE_TABLE}), REGISTER_XLAT_CONTEXT2
macro explicitly specifies the base xlat table goes into .bss by default.
This change affects the existing SynQuacer spm_mm implementation.
plat/socionext/synquacer/include/plat.ld.S linker script intends to
locate ".bss.sp_base_xlat_table" into "sp_xlat_table" section,
but this implementation is no longer available.

This patch adds the base table section name parameter for
REGISTER_XLAT_CONTEXT2 so that platform can specify the
inner & outer WBWA & shareable memory for spm_mm base xlat table.
If PLAT_SP_IMAGE_BASE_XLAT_SECTION_NAME is not defined, base xlat table
goes into .bss by default, the result is same as before.

      TF-A: Fix BL31 linker script error · 34dd1e96
      Alexei Fedorov authored 
      

The patch fixes BL31 linker script error
"Init code ends past the end of the stacks"
for platforms with number of CPUs less than 4,
which is caused by __STACKS_END__ address being
lower than __INIT_CODE_END__.
The modified BL31 linker script detects such cases
and increases the total amount of stack memory,
setting __STACKS_END__ = __INIT_CODE_END__, and
CPUs' stacks are calculated by BL31 'plat_get_my_stack'
function accordingly. For platforms with more than 4 CPUs
and __INIT_CODE_END__ < __STACKS_END__ stack memory does not
increase and allocated CPUs' stacks match the existing
implementation.
The patch removes exclusion of PSCI initialization
functions from the reclaimed .init section in
'arm_reclaim_init.ld.S' script, which increases the
size of reclaimed memory region.
