* Updates driver library to v2.3.1 (2018q1) for bugfixes and convenience functions
* Provides library in correct format (2-byte wchar_t flag) for compiling with ARMCC (#6695 uncovered by #6577)
* Reverts to using a statically-allocated packet buffer since malloc is not thread-safe (and the asserts have been turned on)
This commit changes the conversion function to do all the calculation
inside the HAL in ticks instead of microseconds.
The conversion will be done in Mbed OS side.
As SystemCoreClock is not a constant, it can not be used to initialise
the ticker_info_t structure.

- fix compiler warning message of flash_api.c
- fix compiler warning message of startup_ADuCM4050.c
- eliminate absolute address of ROM tables
- add MBED_APP_START and MBED_APP_SIZE to linker scripts
* Consolidated device_has and macros to the main MCU targets.
* Moved errata configuration to mbed_lib.json for HAL implementation.
* Moved clock configuration to mbed_lib.json for HAL implementation.
* Moved UART configuration to mbed_lib.json for HAL implementation.
Instance counter keeps track of how many objects have been
initialized and freed. On the first object the instance is
enabled and on the last object the instance is disabled.
Serial implementation uses UARTE instead of UART peripheral:
* EasyDMA is used for reading and writing data.
* Triple buffering for receiving data.
See README for full description.
When possible, the I2C HAL will now use the TWI driver in SDK 14.
The manual I2C API still maps onto the old TWI peripheral directly
because the TWI driver doesn't provide the needed low-level functionality.
The NRF52 series can map digital signals to any physical pin which
makes it challenging to associate pin names with hardware instances.
pinmap_ex:
Keep track of which hardware instance is in use and what pins are
associated with it. Currently only supports I2C and SPI, but
provides a mechanism for allocating the shared I2C/SPI hardware.
PeripheralPinsDefault:
Optional pin map for pre-assigning hardware instances at compile
time. This makes it easier to optimize hardware utilization.
* Add NRF_SD_BLE_API_VERSION=5 macro to MCU_NRF52832 target

object will turn the TRNG off for the other objects. This fix
adds a counter to ensure that only when the last object is
destroyed will it cause the TRNG to be disabled.
* The corner case where a user request 0 bytes is correctly handled

Add fstorage and fds from Nordic SDK for SoftDevice compatible
flash storage. Mbed HAL flash API mapped to use fstorage API
to ensure write and erase doesn't conflict with BLE operation.
Various bug fixes:
* Moved SPIM3 location in vector table based on new location in SDK 14.2.
* Updated vector table entries and size in startup code and linker scripts.
* Added missing vector table RAM section to IAR linker script.
Ability to swap SoftDevices using the mbed configuration system.
For example, build NRF52840_DK without SoftDevice:
"target_overrides": {
"*": {
"target.MERGE_SOFT_DEVICE": false,
"target.extra_labels_remove": ["SOFTDEVICE_COMMON", "SOFTDEVICE_S140"],
"target.extra_labels_add": ["SOFTDEVICE_NONE"]
}
}
Pinned down vector table to beginningn of RAM.
Critical section enter/exit is now delegated to Nordic SDK's
sd_nvic_critical_region_enter
sd_nvic_critical_region_exit
When the SoftDevice is not included these functions map to
__disable_irq
__enable_irq
Initial commit for separating NRF52 code from the NRF51 and for
combining the NRF52832 and NRF52840 SDK to version 14.
nRF5_SDK_14.2.0_17b948a.zip has been used as baseline.
The folders in SDK/components:
* ble
* boards
* device
* drivers_nrf
* libraries
* softdevice
have been copied to TARGET_NORDIC/TARGET_NRF52/TARGET_SDK14.
Each folder contains a README.md file describing any modifications
made to that particular folder. Most common operation is deletion
of files.
If the need arise in the future the missing files can be added again.
The SoftDevices have been moved to TARGET_SOFTDEVICE_x folders for
flexible selection.
ble.h has been renamed to nrf_ble.h to avoid namespace clash with
mbed OS BLE.

STDOUT.
Usage:
* Define pin names STDIO_UART_RTS for Rx-flow-control and
STDIO_UART_CTS for Tx-flow-control.
* Set target.console-uart-flow-control. Valid options are:
null, RTS, CTS, and RTSCTS.
Replace looping construct with actual block writes.
Transaction in spi_master_block_write funtion is protected by critical
section to ensure it is completed without interruption. A hardware
limitation may cause data corruption if the TX fifo is allowed to run
empty.

Since revision 5499db1 (mbed-os-5.6.0) a hardfault occurs after a power-cycle.
It doesn't occur after a reset when the application has been downloaded using
drag-and-drop or via debugger. This is probably the reason why this problem
isn't detected when testing new mbed releases.
The hardfault occured in hal_sleep(). Adding a __NOP after __WFI solves the
problem although I don't fully understand why.
- Revision ca661f9 is the last revision where the problem doesn't occur.
- The problem doesn't occur when compiling with GCC instead of ARM compiler
- This issue describes a similar, but not identical problem and led me to test adding a __NOP: https://github.com/ARMmbed/mbed-os/issues/5065

Tests have shown that there is hich-up on MSI clock during the setup phase.
If this stabilization phase happens when application has restarted again
this can have side effects, like grambled UART characters typically.
So we're adding a delay before hading-over back to application.
With this modification, on NCULEO_L476RG, the wake-up time is increased
from 2ms to 2,5ms.
If possible this should be improved in the future to save 500 microseconds
of wak-up time. See TODO
There are cases where HW registers are found in unpexcepted state when
exiting Deep Sleep only few micro-seconds after it was entered.
By using an internal clock that does not depend on anythin and clocking
the system without using PLL, this allows SetSysClock default configuration
to run fine whatever possible configuration we find the HW in when
exiting Deep Sleep.
Also we shall restore interrupts only after all cloks are back to
expected running state.
This patchs adds TRNG support using the upstreamed, open-source, TZ-TRNG
driver.
It also implements the HAL for TRNG and add it in features.

* (.ARM.exidx) and *(.init_array) must be placed explicitly, otherwise it is shared between two regions, and the linker is unable to decide where to place it.
This patch changes the linker files and defines to use the ZBT SSRAM
instead of the FPGA Block RAM for code and data.
The section 4.1.1, Code and RAM memory map, of the CM3DS Eval RTL and
testbench user guide explains the available memories.
This switch improves code memory from 256 kB to 4 MB and data memory
from 128 kB to 4 MB.
However, the ZBT SSRAM1 for code memory begins at 0x00400000 while the
processor can only boot at address 0x00000000 which means that it
expects the vector table to be at that address. That is why we have to
create 2 load regions in the linker scripts: one with only the vector
table at address 0x0 and one with code + data at address 0x00400000.
Because of these two load regions, linker will produce different
behaviours:
* GCC_ARM and IAR will only create 1 binary with both load regions
padding with 0 in between. The binary will then be very large (at least
4 MB) and the flash process will take longer.
* ARM and ARMC6 will create 2 binaries for the two load regions. The
load addresses of the two binaries can be written in the images.txt file
on the MPS2 board. You can also use the --bincombined option of fromelf
utility to produce only 1 large binary.
This patch also adds the memory_zones.h file to try to put in common all
the memory addresses that were previously hard coded in the linker
scripts / startup files.
With that patch in, the simplest option is to directly use the .elf file
with the MPS2, which is only possible with mbb_v225.ebf and more recent
firmwares. It will now be the default for CM3DS.
This commit works with greentea thanks to the now merged pull request
ARMmbed/htrun#181 in order to copy .elf file to the MPS2 board.

Originally, we use 2 H/W timers for us_ticker/lp_ticker, one for counting and the other for alarm.
With H/W timer running in continuous mode, we could use just one H/W timer for counting/alarm simultaneously.

This patch changes the way data is put in the TX_DATA_PORT register when
sending packet over Ethernet.
When this driver is compiled with release compilation profile
(space optimization compiler options) with Arm compiler version 5,
the line:
SMSC9220->TX_DATA_PORT = *pktptr;
generates the assembly instruction to get the pktptr pointed value:
LDM r2!, {r3}
with pktptr = r2
However, the code does not prevent the pktptr value from being unaligned
(to a 32 bits boundary) in that zone and the LDM instruction causes a
HardFault if this is the case. When the compiler option is not activated
(debug and develop compilation profiles), the compiler generates LDR
instruction instead which does not cause a HardFault.
The ARM v7-M states page B3-601: "Unaligned load-store multiples and
word or halfword exclusive accesses always fault."
To face that problem, we check if the data pointer is aligned or not. If
it is, we apply the same algorithm than before. If not, a local variable
is created and we copy in it, byte per byte, the contents at the
unaligned pointer. However, it will impact performances adding 8
instructions (one LD and one ST for each copied byte).

How you write and ersae the flash on the NRF52 changes depending on
whether the SoftDevice is enabled or not.
This change does a runtime check before erasing and writing, and
then chooses the correct function to perform the action.
Delta calculation from lp_ticker_set_interrupt() function:
delta_us = timestamp > now_us ? timestamp - now_us : (uint32_t)((uint64_t)timestamp + 0xFFFFFFFF - now_us);
Lets assume that timestam == now_us.
Expected delta value should be 0 and in this current version is 0xFFFFFFFF.
The following condition:
timestamp > now_us
should have the following form:
timestamp >= now_us
Additionally modified us ticker driver to provide the same logic.
Fix Details: HAL API for loguart is different that UART. Initially we
didnt have support for loguart in the mbed api. These changes have been
made to support the loguart from the mbed api by using the correct HAL
api calls
Renesas mbed boards incorporate NVIC Wrapper because Cortex-A9 use GIC. For example, NVIC_SystemReset() is defined in nvic_wrapper.c and declared in nvic_wrapper.h.
Because I removed one of include processing accidentally, I fixed the lack.
This supplements PR #5890.
The rework includes the following:
1. Remove ticker overflow handling because upper layer (mbed_ticker_api.c) has done with it.
This makes us_ticker/lp_ticker implementation more succinct and avoids potential error.
2. Refine timer register access with low-power clock source
