      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: memctrl_v2: remove weakly defined TZDRAM setup handler · f561a179
      Varun Wadekar authored 
      

This patch removes the per-platform, weakly defined TZDRAM setup handler,
as all affected platforms implement the actual handler.

      Tegra: remove weakly defined per-platform SiP handler · ba37943d
      Varun Wadekar authored 
      

This patch removes the weakly defined per-platform SiP handler
as all platforms implement this handler, defeating the need for
a weak definition.

      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;

      Tegra: prepare boot parameters for Trusty · 2783205d
      Varun Wadekar authored 
      This patch saves the boot parameters provided by the previous bootloader
during cold boot and passes them to Trusty. Commit 06ff251e

 introduced
the plat_trusty_set_boot_args() handler, but did not consider the boot
parameters passed by the previous bootloader. This patch fixes that
anomaly.

      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: dummy support for the io_storage backend · 8d56e24b
      Varun Wadekar authored 
      

This patch provides dummy macros and platform files to compile
the io_storage driver backend. This patch is necessary to
remove the "--unresolved=el3_panic" linker flag from Tegra's
makefiles and allow us to revert this workaround, previously
suggested by the ARM toolchain team.

The "--unresolved=el3_panic" flag actually was a big hammer that
allowed Tegra platforms to work with armlink previously but it
masks legit errors with the code as well.
