      stm32mp1: use stm32mp_get_ddr_ns_size() function · 5813e6ed
      Yann Gautier authored 
      

Instead of using dt_get_ddr_size() and withdrawing the secure and shared
memory areas, use stm32mp_get_ddr_ns_size() function.

      stm32mp1: set XN attribute for some areas in BL2 · 9c52e69f
      Yann Gautier authored 
      

DTB and BL32 area should not be set as executable in MMU during BL2
execution, hence set those areas as MT_RO_DATA.

      stm32mp1: dynamically map DDR later and non-cacheable during its test · 84686ba3
      Yann Gautier authored 
      

A speculative accesses to DDR could be done whereas it was not reachable
and could lead to bus stall.
To correct this the dynamic mapping in MMU is used.
A first mapping is done for DDR tests with MT_NON_CACHEABLE attribute,
once DDR access is setup. It is then unmapped and a new mapping DDR is done
with cacheable attribute (through MT_MEMORY) to speed-up BL33 (or OP-TEE)
load.

The disabling of cache during DDR tests is also removed, as now useless.
A call to new functions stm32mp_{,un}map_ddr_non_cacheable() is done
instead.

PLAT_XLAT_TABLES_DYNAMIC is activated globally as used in BL2 and BL32.

BL33 max size is also updated to take into account the secure and shared
memory areas. Those are used in OP-TEE case.

      stm32mp1: add a function to get non-secure DDR size · e6cc3ccf
      Yann Gautier authored 
      

This function gets the DDR size from DT, and withdraws (if defined) the
sizes of secure DDR and shared memory areas.
This function also checks DT values fits the default DDR range.
This non-secure memory is available for BL33 and non-secure OS.

      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;

      stm32mp1: add authentication support for stm32image · 4bdb1a7a
      Lionel Debieve authored 
      

This commit adds authentication binary support for STM32MP1.
It prints the bootrom authentication result if signed
image is used and authenticates the next loaded STM32 images.
It also enables the dynamic translation table support
(PLAT_XLAT_TABLES_DYNAMIC) to use bootrom services.

      Replace __ASSEMBLY__ with compiler-builtin __ASSEMBLER__ · d5dfdeb6
      Julius Werner authored 
      

NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__.

All common C compilers predefine a macro called __ASSEMBLER__ when
preprocessing a .S file. There is no reason for TF-A to define it's own
__ASSEMBLY__ macro for this purpose instead. To unify code with the
export headers (which use __ASSEMBLER__ to avoid one extra dependency),
let's deprecate __ASSEMBLY__ and switch the code base over to the
predefined standard.
