      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.

      Tegra186: mce: fix MISRA defects · ab712fd8
      Anthony Zhou authored 
      

Main fixes:

* Added explicit casts (e.g. 0U) to integers in order for them to be
  compatible with whatever operation they're used in [Rule 10.1]
* Force operands of an operator to the same type category [Rule 10.4]
* Added curly braces ({}) around if/while statements in order to
  make them compound [Rule 15.6]
* Added parentheses [Rule 12.1]
* Voided non C-library functions whose return types are not used [Rule 17.7]

      Tegra: memctrl: check GPU reset state from common place · f5f64e4d
      Varun Wadekar authored 
      

This patch moves the GPU reset state check, during VideoMem resize, to the
common SiP handler, to reduce code duplication.

      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.

      Tegra186: enable support for simulation environment · abd3a91d
      Varun Wadekar authored 
      

The Tegra simulation environment has limited capabilities. This patch
checks the chip's major and minor versions to decide the features to
enable/disable - MCE firmware version checking is disabled and limited
Memory Controller settings are enabled

      Tegra186: save/restore BL31 context to/from TZDRAM · 68c7de6f
      Varun Wadekar authored 
      

This patch adds support to save the BL31 state to the TZDRAM
before entering system suspend. The TZRAM loses state during
system suspend and so we need to copy the entire BL31 code to
TZDRAM before entering the state.

In order to restore the state on exiting system suspend, a new
CPU reset handler is implemented which gets copied to TZDRAM
during boot. TO keep things simple we use this same reset handler
for booting secondary CPUs too.

      Tegra186: re-configure MSS' client settings · e64ce3ab
      Varun Wadekar authored 
      

This patch reprograms MSS to make ROC deal with ordering of
MC traffic after boot and system suspend exit. This is needed
as device boots with MSS having all control but POR wants ROC
to deal with the ordering. Performance is expected to improve
with ROC but since no one has really tested the performance,
keep the option configurable for now by introducing a platform
level makefile variable.

      Tegra186: implement support for System Suspend · 50402b17
      Varun Wadekar authored 
      

This patch adds the chip level support for System Suspend entry
and exit. As part of the entry sequence we first query the MCE
firmware to check if it is safe to enter system suspend. Once
we get a green light, we save hardware block settings and enter
the power state. As expected, all the hardware settings are
restored once we exit the power state.
