Reimplement atomic code in inline assembly. This can improve
optimisation, and avoids potential architectural problems with using
LDREX/STREX intrinsics.
API further extended:
* Bitwise operations (fetch_and/fetch_or/fetch_xor)
* fetch_add and fetch_sub (like incr/decr, but returning old value -
aligning with C++11)
* compare_exchange_weak
* Explicit memory order specification
* Basic freestanding template overloads for C++
This gives our existing C implementation essentially all the functionality
needed by C++11.
An actual Atomic<T> template based upon these C functions could follow.
Purposes:
* Remove MbedOS-specific code from system_psoc6_{cm4,cm0plus}.c
to simplify updates to new PDL version (startup code is part of PDL).
* Unify mbed_sdk_init initialization sequence for both CPU cores.
This change is non-functional, sequence itself is not changed for any
of the PSoC 6 M4/M0 PSA/non-PSA targets.
According to their cmsis.h, FPU is present, so change targets.json to
use it.
* ARM_MPS2_M4: already was Cortex-M4F
* ARM_MPS2_M7: Cortex-M7 -> M7FD
* FVP_MPS2_M4: Cortex-M4 -> M4F
* FVP_MPS2_M7: Cortex-M7 -> M7FD
If they do not in fact have FPU, then cmsis.h should be modified to set
`__FPU_PRESENT` to 0. This will currently cause compilation problems
with ARMC6, but I'll be submitting a fix for that.
On NUC472, on wake-up from power-down mode, we may meet hard fault or some other
unknown error. Before its cause is found, we enter idle mode instead for a workaround.
To simulate power-down mode with idle mode, we also disable us_ticker during
power-down period.
PDL Flash API requires that the data buffer is 32-bit aligned, otherwise
programming can hung. Buffer declared as uint8_t array is not always
properly aligned, e.g. with gcc 6 when -Os option is used.
Flash driver 3.30:
Moved ipcWaitMessageStc structure to the RAM section called ".cy_sharedmem"
Added support Secure Boot devices
Moved CY_FLASH_EFFECTIVE_PAGE_SIZE to flash_api.c (the macro is Mbed specific).
GeneratedSource folders are BSP specific. No parts of the kit BSP can be reused
as generic chip support package. Remove TARGET_CY8C62XX directory,
and use flat BSP inheritance model:
MCU_PSOC6 -> MCU_PSOC6_M4 -> CY8CKIT_062_WIFI_BT
MCU_PSOC6 -> MCU_PSOC6_M0 -> CY8CKIT_062_WIFI_BT_M0

These file changes provide small fixes for various targets
on MPS2 platform in order to work properly and pass all
Greentea test cases. The __initial_sp has been explicitly set
in the targets' startup files, and also INITIAL_SP has been
given a different value. The values have been extracted from
the specific targets' Application Note documentation.
Affected targets are: ARM_MPS2_M0, ARM_MPS2_M0P, ARM_MPS2_M3,
ARM_MPS2_M4 and ARM_MPS2_M7.

Spotted in compiler warnings - code was trying to access a non-existent
second security control block, rather than access the settings for the
second APB bridge in the first and only security control block.
The hal code for this target uses "const volatile" types inside of
structs, which are non-trivially copyable in clang (used by ARMC6). This
causes the build to fail.
Here's the commit that changed this in clang:
a3d727ba77
It seems this was reverteed some time ago in clang, but ARMC6 may not
be up to date.
To have the flexibilty in application; to use any of the section
(data/bss/heap) without updating linker script in every use case,
following decisions are made:
1. Fixed size and small sections moved to SRAM2 (32K)
Vectors
Crash data
Remaining section - RW / ZI
2. Large memory space should be used for variable sections
RW/ZI
Heap - (Minimum - 0x12000)
Stack - At bottom
Please note the heap address of the both the banks must not be contigious else
GCC considers it to be single memory bank and does allocation across the banks,
which might result into hard-fault

This change moves all PDL drivers into common source and include
directories to alleviate issue with Windows version of GNU Make 4.x
maximum command line length limit.
New `target.console-uart` option added to indicate whether a target has
a console UART on STDIO_UART_TX/RX/RTS/CTS pins. (The existing option
`target.console-uart-flow-control` indicates whether RTS and or CTS is
available in addition to TX and RX).
The option defaults to true, and is currently true on all platforms. It
only applies if DEVICE_SERIAL is true, so no need to go through and mark
it false for non-SERIAL platforms.
An application can turn off target.console-uart to save ROM/power/etc if
they don't want to use the serial console. If this is turned off, the
console won't be activated for stdin/stdout, but the application is
still free to open `UARTSerial(STDIO_UART_TX, STDIO_UART_RX)`
themselves.
Since commit 12c6b1bd8, the i.MX RT1050 has effectively had its data
cache disabled, as the SDRAM was marked Shareable; for the Cortex-M7,
shareable memory is not cached.
This was done to make the Ethernet driver work without any cache
maintenance code. This commit adds cache maintenance and memory barriers
to the Ethernet driver, and removes the Shareable attribute from the
SDRAM, so the data cache is used again.
Cache code in the base fsl_enet.c driver has not been activated - the
bulk of it is in higher-level Read and Write calls that we're not using,
and there is one flawed invalidate in its initialisation. Instead
imx_emac.cpp takes full cache responsibility.
This commit also marks the SDRAM as read/write-allocate. As the
Cortex-M7 has its "Dynamic read allocate mode" to automatically switch
back to read-allocate in cases where write allocate is working poorly
(eg large memset), this should result in a performance boost with no
downside.
Activating write-allocate is also an attempt to provoke any flaws in
cache maintenance - the Ethernet transmit buffers for example will be
more likely to have a little data in the cache that needs cleaning.
Fixed interrupt vector settings on M0 core. Wrong vector settings prevented
LP_TICKER from working, resulting in deep sleep tests failing on M0
or PSA variant.
Internal channels use is enabling ADC "internal path" which needs
to be disabled after measurement.
Same applied here for WB family as was done for others in #10143.
Typically the RTC clock is configured by RTC driver itself.
RNG on the other hand is shared with M0+ core and it is expected that
M4 turns it on at boot time.
When doing so, do not disbale GPIO clocks as they may be used by other
drivers !
As a result, debug will be disabled by default, but can be enabled by
either modifying code or selecting MBED debug profile.
Review HSE clock initialization to match with latest CUBE firmware.
Also there is no need to set the full clock tree again after deep sleep exit.
With this change we get a stable deep sleep mode (when allowed by CORDIO stack).
Until the CMSIS pack device name is officially deployed.
then we'll the name as can be found in Keil CMSIS pack

There is no need to add FIRST attribute to MAPPING_TABLE as the default
ordering is alphabetical order.
With this change, we don't have any warning with MBED2 and the sections
are properly ordered anyway in BLE cases.
In case of mbed2, BLE feature is not built.
As there is a MAPPING_TABLE in BLE feature which is not compiled in case
of mbed2, the linker reported the below error
[ERROR] "C:/Data/Workspace/mbed/BUILD/test/NUCLEO_WB55RG/ARM/MBED_2/
.link_script.sct", line 65 (column 6): Error: L6236E:
No section matches selector - no section to be FIRST/LAST.
Solution is to check whether BLE is enabled.
These files are not BLE specific, but also needed for some clock setting
for instance.
In order to compile an MBED2 application, we need to move the files.
- move hw_conf.h file to targets/TARGET_STM/TARGET_STM32WB directory as
this is used also out of BLE feature.
- create a dedicated hal_deepsleep function as the behavior in WB is a lot
different from other existing STM32 targets
- update clock tree configuration to directly clock the entire tree @ 32MHz
out of HSE. This is needed as we want to let the M0 core running without
any change on M0-side of clocks when M4 enters /exits deep sleep.
Needed for PSoC to deep-sleep for more than 2 seconds
Max sleep with 16 bit lp_ticker (before this change) : 2sec
Max sleep with 32 bit lp_ticker (after this change) : 36hours
The cache must be refreshed when we erase or program flash memory.

The OS timer of RZ/A1 uses P0 clock, so until now it has been set the value of P0 clock in SystemCoreClock.
Changed the system clock value to set to SystemCoreClock.
Changed to refer to P0 clock macro instead of SystemCoreClock in OS timer processing.
Nuvoton targets below don't provide SPI-bus SD on-board, identified by 'SD' in
target component list. Instead, these targets provide SD-bus SD on-board, identified
by unofficial 'NUSD', driver of which is provided outside mbed-os tree. So 'SD' must
be removed to reflect the truth.
