Manish V Badarkhe 49e9ac2811 refactor(plat/arm): replace FIP base and size macro with a generic name
Replaced PLAT_ARM_FIP_BASE and PLAT_ARM_FIP_MAX_SIZE macro with a
generic name PLAT_ARM_FLASH_IMAGE_BASE and PLAT_ARM_FLASH_IMAGE_MAX_SIZE
so that these macros can be reused in the subsequent GPT based support
changes.

Manish V Badarkhe a07c101a4d plat/arm: Move fconf population after the enablement of MMU
In BL2, fw_config's population happened before the cache gets
enabled.
Hence to boost the performance, moved fw_config's population
after cache gets enabled (i.e. after MMU gets enabled).

Mark Dykes 436367966f Merge "Unify type of "cpu_idx" across PSCI module." into integration 2020-01-10 19:39:17 +00:00
Deepika Bhavnani 5b33ad174a Unify type of "cpu_idx" across PSCI module.
NOTE for platform integrators:
   API `plat_psci_stat_get_residency()` third argument
   `last_cpu_idx` is changed from "signed int" to the
   "unsigned int" type.

Issue / Trouble points
1. cpu_idx is used as mix of `unsigned int` and `signed int` in code
with typecasting at some places leading to coverity issues.

2. Underlying platform API's return cpu_idx as `unsigned int`
and comparison is performed with platform specific defines
`PLAFORM_xxx` which is not consistent

Misra Rule 10.4:
The value of a complex expression of integer type may only be cast to
a type that is narrower and of the same signedness as the underlying
type of the expression.

Based on above points, cpu_idx is kept as `unsigned int` to match
the API's and low-level functions and platform defines are updated
where ever required

Vishnu Banavath c20c05252c drivers: add a driver for snoop control unit
The SCU connects one to four Cortex-A5/Cortex-A9 processors
to the memory system through the AXI interfaces.

The SCU functions are to:
- maintain data cache coherency between the Cortex-A5/Cortex-A9
  processors
- initiate L2 AXI memory accesses
- arbitrate between Cortex-A5/Cortex-A9 processors requesting
  L2 accesses
- manage ACP accesses.

Snoop Control Unit will enable to snoop on other CPUs caches.
This is very important when it comes to synchronizing data between
CPUs. As an example, there is a high chance that data might be
cache'd and other CPUs can't see the change. In such cases,
if snoop control unit is enabled, data is synchoronized immediately
between CPUs and the changes are visible to other CPUs.

This driver provides functionality to enable SCU as well as enabling
user to know the following
- number of CPUs present
- is a particular CPU operating in SMP mode or AMP mode
- data cache size of a particular CPU
- does SCU has ACP port
- is L2CPRESENT

Usama Arif ec885bacb2 a5ds: add multicore support
Enable cores 1-3 using psci. On receiving the smc call from kernel,
core 0 will bring the secondary cores out pen and signal an event for
the cores. Currently on switching the cores is enabled i.e. it is not
possible to suspend, switch cores off, etc.

Usama Arif e231f3a5f4 a5ds: Hold the secondary cpus in pen rather than panic
For the secondary CPUs, hold the cpu in wfe rather then panic.
This will be needed when multicore support is added to a5ds as
the smc call will write to the hold base and signal an event to
power on the secondary CPUs.

Usama Arif 00c7d5aca3 plat/arm: Introduce A5 DesignStart platform.
This patch adds support for Cortex-A5 FVP for the
DesignStart program. DesignStart aims at providing
low cost and fast access to Arm IP.

Currently with this patch only the primary CPU is booted
and the rest of them wait for an interrupt.
