I modified the _page_program() because when the request of the size exceeding the maximum size(256 byte) per one writing of Flash recieved, it was not able to loop the writing with sifting the address every 256 byte.
Also I modified the return value of flash_get_page_size() because I found that the minimum size per one writing of Flash is 1 byte by reviewing Flash spec.
"FLASH_PAGE_SIZE" macro's value is remain 256, it doesn't be used at flash_get_page_size(), used at _page_program() for refferencing of the maximum page size.
Although other venders implement this feature by using RTC, in my H/W(RZ_A1), I cannot use RTC because it does not satisfy the spec of LP Ticker (ms order and low frequency between 8 KHz and 64 KHz).
Therefore I implemented this feature by creating 1024 division by MTU2(Multi function Timer pulse Unit 2) in order to satisfy this spec.
As a result of investigating, the most unaffected channel among MTU2 placed on GR-PEACH and GR-LYCHEE was channel 3, so I use channel 3 for this feature.
- mbed_drv_cfg.h
I added a macro of MTU2 channel to this file for commonalizing code for GR-PEACH and GR-LYCHEE, and referenced it's macro at us_ticker.c.
- targets.json
I added a macro for enabling LP Ticker.
- mtu2.c mtu2.h
I defined fuction of MTU2's clock supply and stop.
Because MTU2 is utilized by pwm driver too, those function were referenced at lp_ticker driver and pwm driver.
- lp_ticker.c lp_ticker_init()
In order to satisfy the LP Ticker spec, I implemented by creating 1024 division by MTU2.
When an interrupt is required, it will be set with ticker_set_interrupt().
- lp_ticker.c lp_ticker_free()
This function stops the counting and powerdown the lp_ticker.
- lp_ticker.c lp_read()
This function returns the timer counter of MTU2.
- lp_ticker.c lp_ticker_set_interrupt()
In order to satisfy specifications, I implemented lp_ticker_set_interrupt() function.
- lp_ticker.c lp_ticker_fire_interrupt()
In order to satisfy spec, I implemented lp_ticker_fire_interrupt() function.
Also I added GIC_EnableIRQ for allowing the interrupt at end of function.
- lp_ticker.c lp_ticker_get_info()
To satisfy the spec, I implemented lp_ticker_get_info() function. The value of freq includes rounding off.
i2c_api implementation for NRF52 does a disable() followed by uninit().
The uniinit() implementation in NRF drivers layer makes another call to
disable. This throws off the state of the I2C instance leading to an
assert. Since the disable is only invoked from the I2C API layer for
Nordic, remove this redundant call.

The ITM must be initialized before the SoftDevice, but due to the
lazy initialization in C++ on (at least) GCC the ITM init call
might happen too late.
This commit moves the initialization code into the NRF52 system
startup file.
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
