drivers: stm32_rtc: introduce STM32 RTC driver

Driver interface allows to read date&time from RTC device, generate
RTC timestamps and compute time delta between RTC date & time values.

The RTC is a firewall-aware peripheral. It means that the RTC driver is
in charge of configuring its own firewall restrictions and that the RTC
has dedicated firewall configuration registers.

The RTC provide APIs with time structure compatible with linux kernel
driver.

of using the hard coded version.

The configuration with SPMC at S-EL1, part of OP-TEE, keep the FF-A
version at version 1.1 when configured with CFG_NS_VIRTUALIZATION=y as
workaround to remain compatible with Xen. This workaround will not be

core: arm: ffa: use SMC Calling Convention 1.2

Add struct thread_smc_1_2_regs as a replacement for struct
thread_smc_args when dealing with FF-A SMCs. struct thread_smc_1_2_regs
covers the registers x0-x17 to support passing arguments and results
according to SMC Calling Convention (SMCCC) version 1.2.

The difference is that before this change x8-x17 couldn't be used as
argument nor result and the content was preserved. With this patch are
x8-x17 returned as zeroes. New FF-A SMCs can take and return values in
the full range x0-x17.

64-bit SMCCC version 1.1 and earlier specified x4-x17 as unpredictable
or scratch registers. FF-A has specified x0-x7 as argument and result
registers, regardless of SMCCC. This has changed with SMCCC version 1.2
where the two standards harmonize on this.

struct thread_smc_1_2_regs is added in a 32-bit version for
compatibility, but it only covers r0-r7.

core: mm: extend temporary dummy memory map

core_init_mmu_map() uses a temporary dummy memory map for the
virt_to_phys() and phys_to_virt() conversions to avoid asserting while
setting up translation tables before the MMU is enabled. CFG_DYN_CONFIG
will need a larger range of memory since translation tables might not be
allocated from .nozi memory only. So for CFG_DYN_CONFIG extend of end of
the unused memory range that the boot_mem_*() functions allocate memory
from.

Introduce CFG_DYN_CONFIG, enabled by default if CFG_BOOT_MEM is enabled
and CFG_WITH_PAGER disabled. CFG_DYN_CONFIG conflicts with
CFG_WITH_PAGER since the pager uses a different mechanism for memory
allocation.
