072890c1bf arch/arm/src/armv7-m/arm_vectors.c : Add the address alignment.
Add the address alignment to keep the constraint of ARMv7-M architecture same as RAM vector.

ARMv7-M architecture describes the vector table address alignment as following.
The Vector table must be naturally aligned to a power of two
whose alignment value is greater than or equal to (Number of Exceptions supported x 4),
with a minimum alignment of 128 bytes.

I wonder why the implementation of arm_vectors.c does not follow
this constraint of address alignment about ARMv7-M architecture.
Although RAM vector is taken care about it.

I think, as the result it was done by linker script on each board.
At our system, NuttX will be started by bootloader.
To fix the address of entry point(__start) I set the address of entry point to beginning of binary,
so the beginning of binary is not a vector table.
At this case, keeping the address alignment constraint of arm_vectors.c is needed.

16f8966fa9 esp32s2: add simple boot support
The Simple Boot feature for Espressif chips is a method of booting
that doesn't depend on a 2nd stage bootloader. Its not the
intention to replace a 2nd stage bootloader such as MCUboot and
ESP-IDF bootloader, but to have a minimal and straight-forward way
of booting, and also simplify the building.

This commit also removes deprecated code and makes this bootloader
configuration as default for esp32s2 targets and removes the need
for running 'make bootloader' command for it.

e6973c764c riscv/syscall: Optimize user service call performance
This patch changes how user service calls are executed:
Instead of using the common interrupt logic, execute the user service
call directly.

Why? When a user makes a service call request, all of the service call
parameters are already loaded into the correct registers, thus it makes
no sense to first clobber them and then reload them, which is what the
old logic does. It is much more effective to run the system call directly.

During a user system call the interrupts must be re-enabled, which the
new logic does as soon as we know the exception is a user service call
request.

This patch does NOT change the behavior of reserved system calls (like
switch_context), only the user service call request is affected.
