      plat/stm32mp1: fdt helpers for secure aware gpio bank · ccc199ed
      Etienne Carriere authored 
      

New helper functions to get GPIO banks configuration from the FDT.

stm32_get_gpio_bank_pinctrl_node() allows stm32mp platforms to
differentiate specific GPIO banks when these are defined with a specific
path in the FDT.

fdt_get_gpio_bank_pin_count() returns the number of pins in a GPIO bank
as it depends on the SoC variant.

      plat/stm32: Use generic fdt_get_stdout_node_offset() · 7a61114d
      Andre Przywara authored 
      

Now that we have an implementation for getting the node offset of the
stdout-path property in the generic fdt_wrappers code, use that to
replace the current ST platform specific implementation.

      plat/stm32: Use generic fdt_get_reg_props_by_name() · 7ad6d362
      Andre Przywara authored 
      

The STM32 platform port parse DT nodes to find base address to
peripherals. It does this by using its own implementation, even though
this functionality is generic and actually widely useful outside of the
STM32 code.

Re-implement fdt_get_reg_props_by_name() on top of the newly introduced
fdt_get_reg_props_by_index() function, and move it to fdt_wrapper.c.
This is removes the assumption that #address-cells and #size-cells are
always one.

      plat/stm32: Implement fdt_read_uint32_default() as a wrapper · be858cff
      Andre Przywara authored 
      

The STM32 platform code uses its own set of FDT helper functions,
although some of them are fairly generic.

Remove the implementation of fdt_read_uint32_default() and implement it
on top of the newly introduced fdt_read_uint32() function, then convert
all users over.

This also fixes two callers, which were slightly abusing the "default"
semantic.

      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.

      plat/st: correctly check pwr-regulators node · e9d1e5af
      Yann Gautier authored 
      

This warning was issued by cppcheck in our downstream code:
[plat/st/common/stm32mp_dt.c:629] -> [plat/st/common/stm32mp_dt.c:634]:
 (warning) Identical condition 'node<0', second condition is always false

The second test has to check variable pwr_regulators_node.

      plat/st: correct static analysis tool warning · cd4941de
      Yann Gautier authored 
      

Correct the following sparse warnings:
plat/st/common/stm32mp_dt.c:103:5: warning:
 symbol 'fdt_get_node_parent_address_cells' was not declared.
 Should it be static?
plat/st/common/stm32mp_dt.c:123:5: warning:
 symbol 'fdt_get_node_parent_size_cells' was not declared.
 Should it be static?

As those 2 functions are only used by assert(), put them under
ENABLE_ASSERTIONS flag.

      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.
