mbed-os consists of mbed-core and mbed-rtos
mbed-baremetal consists of mbed-core
The main change is for mbed-core. Changing from object library to be interface. This way it allows us to do the above to have 2 main targets for users to use.
This should be backward compatible change as mbed-os target we used contains the same files/options as previously set.
Directories that start with special prefixes (TARGET_, FEATURE_, COMPONENT_) are added to the build based on Mbed target configuration from targets.json instead of calling utility function mbed_add_cmake_directory_if_labels().
The generic code in mbed_ticker_api.c uses run-time polymorphism to
handle different tickers, and has generic run-time calculations for
different ticker widths and frequencies, with a single special-case for
1MHz.
Extend the run-time special casing to handle any conversion cases where
either the multiply or divide can be done as a shift. This is a speed
optimisation for certain platforms.
Add a new option `target.custom-tickers`. If turned off, it promises
that only USTICKER and LPTICKER devices will be used. This then permits
elimination and/or simplification of runtime calculations, saving size
and speed. If either both USTICKER and LPTICKER have the same width, or
same period numerator or denominator, or only one of them exists, then
operations can be hard-coded. This is a significant ROM space saving,
and a minor speed and RAM saving.
We get to optimise all the calculations, but the run-time polymorphism
is retained even if there is only one ticker, as it doesn't
significantly affect code size versus direct calls, and the existence of
lp_ticker_wrapper and various us_ticker optimisations requires it, even
if only LPTICKER is available.
To allow overriding of the boot stack size from the Mbed configuration
system, consistently use MBED_CONF_TARGET_BOOT_STACK_SIZE rather than
MBED_BOOT_STACK_SIZE.
Fixes#10319
Remove all PSA S-mode only code, as it is unused. Only PSA S targets
would use the code, and we've removed those targets in a previous
commit.
Ensure all tests for S-mode code we are deleting is also removed, even
if that code would run in NS-mode. Keep any tests that also test our PSA
emulation support (for single v7-M targets).

All MBED_SPM targets have been removed previously, via commits
5cc66282dd ("PSOC6: remove PSA targets") and 115b09aba43b ("psoc6:
Remove FUTURE_SEQUANA and FUTURE_SEQUANA_M0"). Remove all the dead
MBED_SPM code, as no targets use it.

This is a special case since targets do not provide by default GPIO pin-maps.
This extension is required for FPGA GPIO tests - if some pins have limitations (e.g. fixed pull-up) we need to skip these pins while testing.
To do that we were adding a dummy pin-map with commented out pins that can't be tested because of the limitations.
This solution is redundant and the proposition is to provide a list of restricted gpio pins if required (by default weak implementation is provided with an empty list).
This mechanism will be backward compatible, so the old method with dummy gpio pinmap will also work. The switch from dummy pin-maps to pinmap_gpio_restricted_pins() will be performed in separate commits/PRs.
Substantiation for this is that the STDIO UART peripheral is used by Mbed, so it should never be tested.
Also solve the potential problem with accidenty skipped peripherals in FPGA testing. Currently, we have a one `pinmap_restricted_peripherals()` function for all interfaces (UART, I2C, SPI, etc.).
The problem can be encountered if different interfaces have the same peripheral ids (e.g. `UART_0` = 0, `SPI_0` = 0). In this case, if `UART_0` is on the restricted list, then SPI tests will be also skipped for `SPI_0`.
The good news is that usually, the peripheral ids are the base addresses of the peripheral's register set, but we can't rely on this. It is also good that `pinmap_restricted_peripherals()` at this moment is only required for STDIO UART (Nuvoton and STM).
To solve this issue we will change name of `pinmap_restricted_peripherals()` to `pinmap_uart_restricted_peripherals()`, make STDIO UART restricted by default for all targets and update FPGA test utilily functions to use `pinmap_uart_restricted_peripherals()` to skip only uart peripherals.
In the future if needed we can consider to add support to restrict peripherals of other interfaces(SPI, I2C, etc).
