      Tegra194: se: fix multiple MISRA issues · 8d4107f0
      Varun Wadekar authored 
      

This patch fixes violations for the following MISRA rules

* Rule 8.4  "A compatible declaration shall be visible when an object or
             function with external linkage is defined"
* Rule 10.1 "Operands shall not be of an inappropriate essential type"
* Rule 10.6 "Both operands of an operator in which the usual arithmetic
             conversions are perdormed shall have the same essential type
             category"
* Rule 17.7 "The value returned by a function having non-void return
             type shall be used"

      Tegra: compile PMC driver for Tegra132/Tegra210 platforms · 57c539f9
      Varun Wadekar authored 
      

The PMC driver is used only by Tegra210 and Tegra132 platforms. This
patch removes pmc.c from the common makefile and moves it to the
platform specific makefiles.

As a result, the PMC code from common code has been moved to Tegra132
and Tegra210 platform ports.

      Tegra: remove weakly defined PSCI platform handlers · e44f86ef
      Varun Wadekar authored 
      

This patch removes all the weakly defined PSCI handlers defined
per-platform, to improve code coverage numbers and reduce MISRA
defects.

      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.

      Enable -Wredundant-decls warning check · ca661a00
      Madhukar Pappireddy authored 
      

This flag warns if anything is declared more than once in the same
scope, even in cases where multiple declaration is valid and changes
nothing.

Consequently, this patch also fixes the issues reported by this
flag. Consider the following two lines of code from two different source
files(bl_common.h and bl31_plat_setup.c):

IMPORT_SYM(uintptr_t, __RO_START__, BL_CODE_BASE);
IMPORT_SYM(unsigned long, __RO_START__, BL2_RO_BASE);

The IMPORT_SYM macro which actually imports a linker symbol as a C expression.
The macro defines the __RO_START__ as an extern variable twice, one for each
instance. __RO_START__ symbol is defined by the linker script to mark the start
of the Read-Only area of the memory map.

Essentially, the platform code redefines the linker symbol with a different
(relevant) name rather than using the standard symbol. A simple solution to
fix this issue in the platform code for redundant declarations warning is
to remove the second IMPORT_SYM and replace it with following assignment

static const unsigned long BL2_RO_BASE = BL_CODE_BASE;

      Tegra194: memctrl: fix logic to check TZDRAM config register access · 95397d96
      Steven Kao authored 
      

This patch fixes the logic to check if the previous bootloader has
disabled access to the TZDRAM configuration registers. The polarity
for the bit was incorrect in the previous check.

      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.
