      qemu: fix holding pen mailbox sequence · 33dd33f8
      Etienne Carriere authored 
      

Before this change, plat_secondary_cold_boot_setup reads wake up mailbox
as a byte array but through 64bit accesses on unaligned 64bit addresses.
In the other hand qemu_pwr_domain_on wakes secondary cores by writing
into a 64bit array.

This change forces the 64bit mailbox format as PLAT_QEMU_HOLD_ENTRY_SIZE
explicitly specifies it.

      GIC: Allow specifying interrupt properties · c639e8eb
      Jeenu Viswambharan authored 
      

The GIC driver initialization currently allows an array of interrupts to
be configured as secure. Future use cases would require more interrupt
configuration other than just security, such as priority.

This patch introduces a new interrupt property array as part of both
GICv2 and GICv3 driver data. The platform can populate the array with
interrupt numbers and respective properties. The corresponding driver
initialization iterates through the array, and applies interrupt
configuration as required.

This capability, and the current way of supplying array (or arrays, in
case of GICv3) of secure interrupts, are however mutually exclusive.
Henceforth, the platform should supply either:

  - A list of interrupts to be mapped as secure (the current way).
    Platforms that do this will continue working as they were. With this
    patch, this scheme is deprecated.

  - A list of interrupt properties (properties include interrupt group).
    Individual interrupt properties are specified via. descriptors of
    type 'interrupt_prop_desc_t', which can be populated with the macro
    INTR_PROP_DESC().

A run time assert checks that the platform doesn't specify both.

Henceforth the old scheme of providing list of secure interrupts is
deprecated. When built with ERROR_DEPRECATED=1, GIC drivers will require
that the interrupt properties are supplied instead of an array of secure
interrupts.

Add a section to firmware design about configuring secure interrupts.

Fixes ARM-software/tf-issues#262

      GIC: Add helpers to set interrupt configuration · 22966106
      Jeenu Viswambharan authored 
      

The helpers perform read-modify-write on GIC*_ICFGR registers, but don't
serialise callers. Any serialisation must be taken care of by the
callers.

      ARM platforms: Migrate to using interrupt properties · b2c363b1
      Jeenu Viswambharan authored 
      

An earlier patch added provision for the platform to provide secure
interrupt properties. ARM platforms already has a list of interrupts
that fall into different secure groups.

This patch defines macros that enumerate interrupt properties in the
same fashion, and points the driver driver data to a list of interrupt
properties rather than list of secure interrupts on ARM platforms.  The
deprecated interrupt list definitions are however retained to support
legacy builds.

Configuration applied to individual interrupts remain unchanged, so no
runtime behaviour change expected.

NOTE: Platforms that use the arm/common function
plat_arm_gic_driver_init() must replace their PLAT_ARM_G1S_IRQS and
PLAT_ARM_G0_IRQS macro definitions with PLAT_ARM_G1S_IRQ_PROPS and
PLAT_ARM_G0_IRQ_PROPS macros respectively, using the provided
INTR_PROP_DESC macro.
