This commit represents the second stage of the low power implementations
that are required from Mbed 5.10 onwards. Besides the default hal
implementations (rtc_api.c and sleep.c), the PL031 RTC's native driver
needed to be added. Due to HW limitations in SSE-050 and the CM3DS,
Deep Sleep couldn't be implemented, therefore it is functionally
identical to Sleep (WFI).

This commit represents the first stage of the low power implementations
that are required from Mbed 5.10 onwards. The LP ticker has been
implemented using a CMSDK Dual Timer's both timers (HW prescaler needed
to operate in the specified frequency domain), whereas the us ticker
uses one CMSDK Timer. Besides the default hal implementations (lp_ticker.c
and us_ticker.c), the CMSDK Dual Timer's native driver needed to be added.

Ethernet controller. To ensure proper operation, some methods
needed to be updated in the SMSC9220's native driver as well.
It passes all related Greentea tests, however when supervised by
the Python environment it tends to fail because of Timeout.
The current timeout is set to 1200s that seems to be a little bit short
to finish all test cases, the timeout happens towards the end of the
last test case.

--legacyalign, --no_legacyalign are deprecated from ARMC6 compiler, in order to
remove deprecated flags all linker files (GCC and IAR as well to have uniformity)
should strictly align to 8-byte boundary
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.

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.

Few targets need more than just pending IRQ set. They include some flags to be
set that are checked in IRQ handler. This is the case for targets in this
commit.
This commit adds the UART driver and updates the UART HAL implementation
to use this driver.
It also removes legacy definitions.

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).

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.
This patch updates CMSDK_CM3DS.h to remove the
DMA peripheral memory map and defines, as
that peripheral is not present in the system.
In addition, some define names where updated
concerning rtc. RTC_api was updated accordingly.
This patch also updates SMM_MPS2 to align defines and
comments.
