      Add SCMI support for Juno platform · 40111d44
      Soby Mathew authored 
      

This patch adds the memory map region for the SCMI payload memory
and maps the Juno core indices to SCMI power domains via the
`plat_css_core_pos_to_scmi_dmn_id_map` array.

      CSS: Add SCMI driver for SCP · c04a3b6c
      Soby Mathew authored 
      

This patch adds the SCMI driver for communicating with SCP. The power
domain management and system power management protocol of the SCMI
specification[1] is implemented in the driver. The SCP power management
abstraction layer for SCMI for CSS power management is also added.

A new buid option `CSS_USE_SCMI_DRIVER` is introduced to select SCMI
driver over SCPI.

[1] ARM System Control and Management Interface v1.0 (SCMI)

      Introduce ARM GIC-600 driver · e1c59ab3
      Jeenu Viswambharan authored 
      

ARM GIC-600 IP complies with ARM GICv3 architecture, but among others,
implements a power control register in the Redistributor frame. This
register must be programmed to mark the frame as powered on, before
accessing other registers in the frame. Rest of initialization sequence
remains the same.

The driver provides APIs for Redistributor power management, and
overrides those in the generic GICv3 driver. The driver data is shared
between generic GICv3 driver and that of GIC-600.

For FVP platform, the GIC-600 driver is chosen when FVP_USE_GIC_DRIVER
is set to FVP_GIC600. Also update user guide.

      Add support for Cortex-A75 and Cortex-A55 CPUs · d40ab484
      David Wang authored 
      

Both Cortex-A75 and Cortex-A55 CPUs use the ARM DynamIQ Shared Unit
(DSU). The power-down and power-up sequences are therefore mostly
managed in hardware, and required software operations are considerably
simpler.

      FVP,Juno: switch FVP and Juno to use generic TBBR OID header · 232c6b34
      Masahiro Yamada authored 
      

The header tbbr_oid.h contains OIDs obtained by ARM Ltd.
so there is no good reason to use platform_oid.h

      cert: move platform_oid.h to include/tools_share for all platforms · bb41eb7a
      Masahiro Yamada authored 
      

Platforms aligned with TBBR are supposed to use their own OIDs, but
defining the same macros with different OIDs does not provide any
value (at least technically).

For easier use of TBBR, this commit allows platforms to reuse the OIDs
obtained by ARM Ltd.  This will be useful for non-ARM vendors that
do not need their own extension fields in their certificate files.

The OIDs of ARM Ltd. have been moved to include/tools_share/tbbr_oid.h

Platforms can include <tbbr_oid.h> instead of <platform_oid.h> by
defining USE_TBBR_DEFS as 1.  USE_TBBR_DEFS is 0 by default to keep the
backward compatibility.

For clarification, I inserted a blank line between headers from the
include/ directory (#include <...>) and ones from a local directory
(#include "..." ).
