fire_interrupt function should be used for events in the past. As we have now
64bit timestamp, we can figure out what is in the past, and ask a target to invoke
an interrupt immediately. The previous attemps in the target HAL tickers were not ideal, as it can wrap around easily (16 or 32 bit counters). This new
functionality should solve this problem.
set_interrupt for tickers in HAL code should not handle anything but the next match interrupt. If it was in the past is handled by the upper layer.
It is possible that we are setting next event to the close future, so once it is set it is already in the past. Therefore we add a check after set interrupt to verify it is in future.
If it is not, we fire interrupt immediately. This results in
two events - first one immediate, correct one. The second one might be scheduled in far future (almost entire ticker range),
that should be discarded.
The specification for the fire_interrupts are:
- should set pending bit for the ticker interrupt (as soon as possible),
the event we are scheduling is already in the past, and we do not want to skip
any events
- no arguments are provided, neither return value, not needed
- ticker should be initialized prior calling this function (no need to check if it is already initialized)
All our targets provide this new functionality, removing old misleading if (timestamp is in the past) checks.
The use of mktime was causing a fault when called in interrupt handler because on GCC it lock the mutex protecting the environment, To overcome this issue, this patch add dedicated routine to convert a time_t into a tm and vice versa.
In the process mktime has been optimized and is now an order of magnitude faster than the routines present in the C library.
There is an easy default implementation of spi_master_block_write that
just calls spi_master_write in a loop, so the default implementation
of spi_master_block_write has been added to all targets.

Currently, there is the issue in register setting into serial_format().
The issue is that parameter for baudrate setting is initialed zero in this function.
In baudrate is less 9600bps, the issue occurs. In baudrate is over 9600, not occurs. When call serial_baud() before serial_format(), baudrate override and set with an incorrect value.
Therefore, I fixed register setting not to set the parameter of baudrate setting in serial_format().
I modified the bug in PR #3289. But It seems not enough the changes.
For the reason, It occured the following issue.
https://github.com/ARMmbed/mbed-os/issues/3694
So I reviewed and re-modified about the setting of initial value of interrupt edge in "gpio_irq_init".
Previously, when "length = 0" as failsafe, "return 0" is executed.
But we changed so that only START bit and STOP bit are executed same as other devices.
I modified the TTB setting of RO_DATA area.
The current setting of this area is "not executable".
Therefore, when trying to execute a program placed in this area, a prefetch abort will occur.
So I changed from "Sect_Normal_RO" to "Sect_Normal_Cod".
Until now, when the frequency function of CAN driver was executed, signal no output, and the frequency could not be changed.
Since there was an error in the frequency changing procedure I modified it.
Renesas modified the initial value of interrupt edge in "gpio_irq_init" function.
The value was "both egde(rise and fall)".So we modified it to "low revel".
When the floating-point calculation is executed into the processing which is called from IRQ handlers, VFP register is overwritten.
Therefore, we fixed the issue. we added the process to execute the saving (Push) and the returning (Pop) of VFP register in before and after the appropriate processing.
Bugs are as below.
- In the case of MTU2 mode, modify a problem that does not excute "pwmout_write ()" at the end of "pwmout_pulsewidth_us ()" function.
- In the case of MTU2 mode in "pwmout_period_us ()" function, modify a problem that the executing result of "set_mtu2_duty_again ()" function does not reflect in the register of TGRA_MATCH [] and TGRC_MATCH [].
