      Tegra: remove weakly defined platform setup handlers · 39171cd0
      Varun Wadekar authored 
      

This patch converts the weakly defined platform setup handlers into
actual platform specific handlers to improve code coverage numbers
and some MISRA defects.

The weakly defined handlers never get executed thus resulting in
lower coverage - function, function calls, statements, branches
and pairs.

      Tegra: introduce plat_enable_console() · 117dbe6c
      Varun Wadekar authored 
      

This patch introduces the 'plat_enable_console' handler to allow
the platform to enable the right console. Tegra194 platform supports
multiple console, while all the previous platforms support only one
console.

For Tegra194 platforms, the previous bootloader checks the platform
config and sets the uart-id boot parameter, to 0xFE. On seeing this
boot parameter, the platform port uses the proper memory aperture
base address to communicate with the SPE. This functionality is
currently protected by a platform macro, ENABLE_CONSOLE_SPE.

      Tegra: fix defects flagged by MISRA Rule 10.3 · aa64c5fb
      Anthony Zhou authored 
      

MISRA Rule 10.3, the value of an expression shall not be assigned to
an object with a narrower essential type or of a different essential
type category.

The essential type of a enum member is anonymous enum, the enum member
should be casted to the right type when using it.

Both UL and ULL suffix equal to uint64_t constant in compiler
aarch64-linux-gnu-gcc, to avoid confusing, only keep U and ULL suffix
in platform code. So in some case, cast a constant to uint32_t is
necessary.

      Tegra186: reduce complexity for the 'get_target_pwr_state' handler · 4e1830a9
      Varun Wadekar authored 
      

This patch reduces the code complexity for the platform's 'get_target_pwr_state'
handler, by reducing the number of 'if' conditions and adding helper functions
to calculate power state for the cluster/system.

Tested with 'pmccabe'

      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.

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]

Convert object type to match the type of function parameters
[Rule 10.3]

Force operands of an operator to the same type category [Rule 10.4]

Expressions resulting from the expansion of macro parameters
shall be enclosed in parentheses[Rule 20.7]
