      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.

      delay: timeout detection support · 0711ee5c
      Lionel Debieve authored 
      

Introduce timeout_init_us/timeout_elapsed() delay tracking with CNTPCT.

timeout_init_us(some_timeout_us); returns a reference to detect
timeout for the provided microsecond delay value from current time.

timeout_elapsed(reference) return true/false whether the reference
timeout is elapsed.

Cherry picked from OP-TEE implementation [1].
  [1] commit 33d30a74502b ("core: timeout detection support")

Minor:
- Remove stm32mp platform duplicated implementation.
- Add new include in marvell ble.mk

      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.
