This caused a conflict. As CMSIS update introduced low level init, lets use the types
from CMSIS. We could potentionally use __cmsis_start but as I saw for some targets,
the init routine is slightly different. So rather keep what we have in targets, and just
use types already defined in CMSIS.
Align with mainline BSP and fix relevant bugs:
1. Align with SPI module naming
(1) Remove SPI5
(2) Degrade QSPI0 to SPI4 so that it can use for standard SPI
2. Fix some code lacking GPIO H
3. Implement __PC(...) by following BSP instead of with MBED_CALLER_ADDR()
4. Add SCU_IRQHandler(). Change printf(...) with interrupt-safe error(...)
5. Other minor alignment change
1. Re-organize to make clear for all targets/toolchains support in single startup file
2. Inline assembly syntax is limited, esp. on IAR. Try paving the way for accessing external symbols still in inline assembly instead of re-write in assembly.
Add a "used" attribute to __vector_handlers to fix ARMC6 build with
the "-flto" flag.
(Error: L6236E: No section matches selector - no section to be FIRST/LAST.)
This attribute, attached to a function/variable, means that code must be emitted
for the function even if it appears that the function is not referenced.
1. Enable IAR on non-secure targets
2. Disable IAR on secure targets because:
(1) IAR toolchain bug: As of IAR 8.32, cmse_nonsecure_caller() is not always inlined.
(2) TFM hasn't supported IAR yet.
On M2351, some spaces like SYS/CLK are hard-wired to secure and cannot change.
To access these spaces from non-secure world, we must provide platform-specific NSC
functions. With TFM introduced, we must synchronize NSC calls into TFM to keep TFM
in sync instead of straight NSC calls. To achieve this goal, we go with the following
approach:
1. Like PSA APIs, enforce locked entry through tfm_ns_lock_dispatch().
2. Run platform-specific secure functions in default secure partition, in which SYS/CLK
spaces have been configured to be accessible.
Fix SPI module index error in modidx_ns_tab table in CLK_SetModuleClock_S().
Need to update secure image for this bugfix.
This is also to fix FPGA CI test mbed_hal_fpga_ci_test_shield-spi/
SPI - init/free test all pins.
Nuvoton M2351 was including generic core_armv8mbl.h from CMSIS - we
need it to be more specific to identify the specific core for
wait_ns. Change to core_cm23.h.
RAM/ROM sizes in tools were updated to report entire device size, and in M2351
they were used earlier to report secure/non-secure partition size.
M2351 files are updated to take full RAM/ROM device size and derive secure
and non-secure partition size based on that.
--legacyalign, --no_legacyalign are deprecated from ARMC6 compiler, in order to
remove deprecated flags all linker files (GCC and IAR as well to have uniformity)
should strictly align to 8-byte boundary
1. Rename m2351_stddriver_sup.h/c to stddriver_secure.h/.c for naming consistency
2. Add hal_secure.h to include hal-exported secure functions
3. Change return/argument type in secure functions:
(1) Change int to int32_t
(2) Change PinName to int32_t
(3) Change time_t to int64_t
4. Update secure lib/bin accordingly
