      ti: k3: common: Add support for runtime detection of GICR base address · b5443284
      Andrew F. Davis authored 
      

Valid addresses for GICR base are always a set calculable distance from
the GICD and is based on the number of cores a given instance of GICv3 IP
can support. The formula for the number of address bits is given by the
ARM GIC-500 TRM section 3.2 as 2^(18+log2(cores)) with the MSB set to
one for GICR instances. Holes in the GIC address space are also
guaranteed to safely return 0 on reads. This allows us to support runtime
detection of the GICR base address by starting from GIC base address plus
BIT(18) and walking until the GICR ID register (IIDR) is detected. We
stop searching after BIT(20) to prevent searching out into space if
something goes wrong. This can be extended out if we ever have a device
with 16 or more cores.

      Sanitise includes across codebase · 09d40e0e
      Antonio Nino Diaz authored 
      Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca339

 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

      GIC: Remove lowest priority constants · 35cd9e81
      Jeenu Viswambharan authored 
      

The GIC lowest priority values for each world depends on the number of
priority values implemented in hardware. These constants currently
defined in gic_common.h only meant to enumerate lowest possible
architectural values. Since these values are not used in generic code or
upstream platforms, and that general use of these constants can be
wrong, remove these. Platforms should either define and use these as
appropriate, or determine correct values at run time.

      Standardise header guards across codebase · c3cf06f1
      Antonio Nino Diaz authored 
      

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

      tzc: Fix MISRA defects · af6491f8
      Antonio Nino Diaz authored 
      

The definitions FAIL_CONTROL_*_SHIFT were incorrect, they have been
fixed.

The types tzc_region_attributes_t and tzc_action_t have been removed and
replaced by unsigned int because it is not allowed to do logical
operations on enums.

Also, fix some address definitions in arm_def.h.

      allwinner: Add RSB driver · 103f19f0
      Andre Przywara authored 
      

The "Reduced Serial Bus" is an Allwinner specific bus, bearing many
similarities with I2C. It sports a much higher bus frequency, though,
(typically 3 MHz) and requires much less handholding for the typical
task of manipulating slave registers (fire-and-forget).
On most A64 boards this bus is used to connect the PMIC to the SoC.

This driver provides basic primitives to read and write slave registers,
it will be later used by the PMIC code.

      plat/arm: Move norflash driver to drivers/ folder · aa7877c4
      Antonio Nino Diaz authored 
      

This way it can be reused by other platforms if needed.

Note that this driver is designed to work with the Versatile Express NOR
flash of Juno and FVP. In said platforms, the memory is organized as an
interleaved memory of two chips with a 16 bit word.

Any platform that wishes to reuse it with a different configuration will
need to modify the driver so that it is more generic.
