      drivers: stm32_reset adapt interface to timeout argument · 45c70e68
      Etienne Carriere authored 
      

Changes stm32mp1 reset driver to API to add a timeout argument
to stm32mp_reset_assert() and stm32mp_reset_deassert() and
a return value.

With a supplied timeout, the functions wait the target reset state
is reached before returning. With a timeout of zero, the functions
simply load target reset state in SoC interface and return without
waiting.

Helper functions stm32mp_reset_set() and stm32mp_reset_release()
use a zero timeout and return without a return code.

This change updates few stm32 drivers and plat/stm32mp1 blé_plat_setup.c
accordingly without any functional change.
functional change.

      plat/stm32: Use generic fdt_read_uint32_array() implementation · 52a616b4
      Andre Przywara authored 
      

The device tree parsing code for the STM32 platform is using its own FDT
helper functions, some of them being rather generic.
In particular the existing fdt_read_uint32_array() implementation is now
almost identical to the new generic code in fdt_wrappers.c, so we can
remove the ST specific version and adjust the existing callers.

Compared to the original ST implementation the new version takes a
pointer to the DTB as the first argument, and also swaps the order of
the number of cells and the pointer.

      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.

      clk: stm32mp1: use defines for mask values in stm32mp1_clk_sel array · d4151d2f
      Yann Gautier authored 
      

Rework the macro that eases the table definition: the src and msk fields
are now using MASK and SHIFT defines of each source register.
Some macros had then to be modified: _USART1_SEL, _ASS_SEL and _MSS_SEL to
_UART1_SEL, _AXIS_SEL, and _MCUS_SEL to match register fields.

Note: the mask for RCC_ASSCKSELR_AXISSRC is changed from 0x3 to 0x7
to reflect the size of the register field, even if there are only
3 possible clock sources.

The mask value is also corrected for QSPI and FMC clock selection.

      clk: stm32mp1: move oscillator functions to generic file · f66358af
      Yann Gautier authored 
      

Those functions are generic for parsing nodes from device tree
hence could be located in generic source file.

The oscillators description structure is also moved to STM32MP1 clock
driver, as it is no more used in stm32mp1_clkfunc and cannot be in a
generic file.

      Sanitise includes across codebase · 09d40e0e
      Antonio Nino Diaz authored 
      Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca339

 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

      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
