mbed RTC specifications now dictate that the RTC needs to retain and keep on counting through reset. On Silicon Labs parts, this means the RTC API can not be backed by the Silicon Labs RTC peripheral, since that doesn't provide retention functionality.
Therefore:
* On EFM32GG, EFM32WG, EFM32LG: mbed RTC API is now backed by BURTC.
* On EFM32PG, EFR32MG, EFM32PG12, EFR32MG12: mbed RTC API is now backed by RTCC.
* On EFM32ZG, EFM32HG: mbed RTC API is sadly no longer supported, since these chips don't have retained memory.
I implemented the RTC feature.
The mainly changing is here.
- rtc_init()
Previously, I have initialized the time information register in the function, so the time count was cleaned by every calling rtc_init().
Currently, rtc_init() doesn't stop RTC from counting, and rtc_init() is safe to call repeatedly.
Therefore in order to satisfy specifications,I removed the initialization process of the time information register in the function.
- rtc_free()
Previously, I have initialized the RTC related register same as rtc_init(), so the time count was cleaned by calling rtc_free().
Currently, rtc_free() doesn't stop RTC from counting.
Therefore in order to satisfy specifications,I removed the process and decided not to do anything in the function.
If powerdown the RTC, Supply of the clock to the RTC is stopped, cannot keeping the count.
1. Enable LPTICKER for K22, K24, K64, K66, K82, KL82F, KW24D
2. Change the implementation to only use the LPTMR which reduces
the amount of interrupts generated which is required for tickless
operation

Re-implemented both us_ticker and lp_ticker to match the new API and specifications.
Details:
* On EFM32GG, EFM32WG, EFM32LG, EFM32HG, EFM32ZG: Use the RTC peripheral to back lp_ticker, and a TIMER to back us_ticker.
* On EFM32PG, EFR32MG, EFM32PG12, EFR32MG12: Use the RTCC peripheral to back lp_ticker (dual-purpose, also used to back RTC), and a TIMER to back us_ticker.

I implemented the SLEEP feature for Rnesas mbed boards.
The mainly changing is here.
- hal_sleep()
To satisfy the mbed specificationm, I implemented this function newly by using "sleep" that is one of low power mode that is incorporated in our hardware(RZ_A1).
In the "sleep", peripheral and memory state are maintained, and the peripherals continue to work and can generate interrupts.
- hal_deepsleep()
To satisfy the mbed specificationm, I implemented this function newly by combined using "sleep" and "module standby" that is the low power mode that is incorporated in our hardware(RZ_A1).
The "module standby" is peripheral module's powerdown.
Also in case of our "module standby", it need to read register as dummy when access to each register.
These boards will be re-enabled when sleep driver for them is ready.
Note:
This operation is done by removing "SLEEP" feature from target's "device_has" list (in targets.json config file).
For NRF52_DK removing of "SLEEP" feature causes some timing issues which have influence on tests. In order to successfully disable this board we need to disable also related features like "USTICKER", "LOWPOERTIMER" and slightly modify ticker tests, so they will not be executed if usticker support is not available (by default all targets support us ticker).
Implementation of unified EMAC driver for Renesas mbed boards
Based on the driver so far, Renesas implemented the emac driver for GR-PEACH and VK-RZ/A1H.
The mainly changes is below.
- Add the connection part with LWIP according to the unified emac specification.
- Add three new multicast functions(add, remove, set_all).
The Greentea test netsocket and emac test passed.
Just checking "does the chip have an EMAC" doesn't work - there are
targets using those chips which do not have an Ethernet connector and
don't provide the necessary surrounding infrastructure (eg DISCO_F429ZI,
not providing the board emac config call, and HEXIWEAR not providing PHY
info).
Make the targets that actually do want EMAC define their own local
Freescale_EMAC and STM_EMAC labels, and move the drivers into
the corresponding TARGET_ directories, removing the #ifdefs.
* Since mbed does not overwrite itself, make the flashing routines run out of flash by default
* Report a writeable size of 4 bytes (previously erroneously reported a full eraseable page as the minimum write size)
Initial work by Bartek Szatkowski in https://github.com/ARMmbed/mbed-os/pull/4079,
reworked following review of https://github.com/ARMmbed/mbed-os/pull/5202 to
transform the entire system into C++, retaining the basic functionality.
Bartek's summary:
* Porting ethernet to EMAC
* Updating EMAC to enable multiple interfaces
* Untangling networking classes, making the abstractions a bit clearer to follow, etc
* General refactoring
* Removal of DEVICE_EMAC flag and introducing DEVICE_ETH and DEVICE_WIFI
Revisions since initial branch:
* Remove lwip depencies
* Correct doxygen warnings
* Remove emac_api.h, replace with C++ EMAC abstract class.
* Create OnboardNetworkInterface, and LWIP implementation.
* Mappings since #4079
lwip-interface/nsapi_stack_lwip.c -> LWIPStack.cpp
lwip-interface/ipstack_lwip.c -> LWIPInterface.cpp
netsocket/mbed_ipstack.h -> OnboardNetworkStack.h
hal/emac_api.h -> EMAC.h
* Reinstate use of EthInterface abstraction
* Correct and clarify HW address EMAC ops
* Restore MBED_MAC_ADDR implementation
* Integrate PPP support with LWIP::Interface.
* Convert K64F lwIP driver to K64F_EMAC.
To do:
* Convert emac_stack_mem.h to follow this pattern.
* Figure out DEVICE_ETH/EMAC
* Update all drivers to use EMAC
New directory structure:
* TARGET_SOFTDEVICE_COMMON
* TARGET_SOFTDEVICE_S112
* TARGET_SOFTDEVICE_S132_FULL (MBR + SoftDevice, default)
* TARGET_SOFTDEVICE_S132_OTA (SoftDevice only, for firmware updates)
* TARGET_SOFTDEVICE_S132_MBR (MBR only, for bootloader builds)
* TARGET_SOFTDEVICE_S140_FULL (MBR + SoftDevice, default)
* TARGET_SOFTDEVICE_S140_OTA (SoftDevice only, for firmware updates)
* TARGET_SOFTDEVICE_S140_MBR (MBR only, for bootloader builds)
* TARGET_SOFTDEVICE_NONE
The X_OTA and X_MBR binaries are obtained from the original x_FULL SoftDevice
by splitting it in an MBR part and a SoftDevice part. The MBR is needed for
the bootloader and the SoftDevice for firmware updates.
Build application without SoftDevice:
"target_overrides": {
"*": {
"target.extra_labels_remove": ["SOFTDEVICE_COMMON", "SOFTDEVICE_X_FULL"],
"target.extra_labels_add": ["SOFTDEVICE_NONE"]
}
}
Build application for firmware update using SoftDevice X:
"target_overrides": {
"*": {
"target.extra_labels_remove": ["SOFTDEVICE_X_FULL"],
"target.extra_labels_add": ["SOFTDEVICE_X_OTA"]
}
}
Build bootloader without SoftDevice X:
"target_overrides": {
"*": {
"target.extra_labels_remove": ["SOFTDEVICE_COMMON", "SOFTDEVICE_X_FULL"],
"target.extra_labels_add": ["SOFTDEVICE_X_MBR"]
}
}
The unified NRF51 target and feature BLE directories have been
reorganized to follow the naming and directory structure of the
NRF52 implementation.
This reorganization does not include TARGET_MCU_NRF51822 and
derived targets.
* 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.
* When multiple TRNG objects are initialized, destroying the first
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
and will now return immediately.
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.
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.
Some platforms have interface chips with hardware flow control
enabled by default. This commit adds configurable flow control to
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.
