      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_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.

      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 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.

      stm32mp1: add general SYSCFG management · f33b2433
      Yann Gautier authored 
      

The system configuration controller is mainly used to manage
the compensation cell and other IOs and system related settings.

The SYSCFG driver is in charge of configuring masters on the interconnect,
IO compensation, low voltage boards, or pull-ups for boot pins.
All other configurations should be handled in Linux drivers requiring it.

Device tree files are also updated to manage vdd-supply regulator.
