      Anthony Zhou authored 
      

Main fixes:

Add suffix U for constant [Rule 10.1]

Match the operands type [Rule 10.4]

      Tegra: gpcdma: driver for general purpose DMA · 647d4a03
      Varun Wadekar authored 
      

This patch adds the driver for the general purpose DMA hardware
block on newer Tegra SoCs. The GPCDMA is a special purpose DMA
used to speed up memory copy operations to/from DRAM and TZSRAM.

This patch introduces a macro 'USE_GPC_DMA' to allow platforms
to override CPU based memory operations.

      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.

      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

      tegra: Fix mmap_region_t struct mismatch · 28db3e96
      Andreas Färber authored 
      Commit fdb1964c

 ("xlat: Introduce
MAP_REGION2() macro") added a granularity field to mmap_region_t.

Tegra platforms were using the v2 xlat_tables implementation in
common/tegra_common.mk, but v1 xlat_tables.h headers in soc/*/plat_setup.c
where arrays are being defined. This caused the next physical address to
be read as granularity, causing EINVAL error and triggering an assert.

Consistently use xlat_tables_v2.h header to avoid this.

Fixes ARM-software/tf-issues#548.

      Tegra: memctrl_v1: enable 'xlat_table_v2' library · c05a2197
      Varun Wadekar authored 
      

This patch enables the 'xlat_table_v2' library for the Tegra Memory
Controller driver. This library allows us to dynamically map/unmap
memory regions, with MMU enabled.

The Memory Controller driver maps/unmaps non-overlapping Video Memory
region, to clean it of any secure contents, before it resizes the
region.
