1. Get the value of sp from dump regs when an exception occurs,
to avoid getting the value of fp from up_getsp and causing
incomplete stack printing.
2. Determine which stack the value belongs to based on the value
of SP to avoid false reports of stack overflow

In the lower half UART driver for PIC32MZ architecture, adding the
TIOCxBRK ioctl calls, which allow an application to transmit a UART
line BREAK signal.
This architecture does not support BSD-style BREAK in hardware so our
implementation follows the precedent set in STM32, GD32, and Kinetis
architectures: By default, if only PIC32MZ_UART_BREAKS is configured,
we produce the hardware-native BREAK, which lasts for 12 bit lengths;
if, in addition, PIC32MZ_SERIALBRK_BSDCOMPAT is configured, we
generate a BSD-style BREAK by putting the TX pin in GPIO mode and
driving it low "manually" until told to stop.
* arch/mips/src/pic32mz/Kconfig
(config PIC32MZ_UART_BREAKS): New. Appears as
CONFIG_PIC32MZ_UART_BREAKS in code.
(config PIC32MZ_SERIALBRK_BSDCOMPAT): New. Appears as
CONFIG_PIC32MZ_SERIALBRK_BSDCOMPAT in code.
* arch/mips/src/pic32mz/hardware/pic32mz_pps.h
(__PPS_OUTPUT_REGADDR_TO_GPIO, PPS_OUTPUT_REGADDR_TO_GPIO): New
macros to automatically determine the GPIO port and pin from the
corresponding PPS (Peripheral Pin Select) define. Since there is a
one-to-one correspondence between PPS output mappings and a single
port and pin, these macros avoid writing redundant pin mappings. We
use this when switching the TX pin from UART to GPIO to generate
the BREAK and we could use it in other peripheral drivers in the
future to override hardware behavior.
* arch/mips/src/pic32mz/pic32mz_serial.c
(struct up_dev_s): Add new field 'brk' to indicate line break in
progress when built with PIC32MZ_UART_BREAKS. If generating BSD-
compatible BREAKs, also add tx_gpio, tx_pps_reg, and tx_pps_val, to
let us toggle the pin between UART and GPIO modes.
(up_ioctl): Add cases for TIOCSBRK and TIOCCBRK to turn BREAK on and
off, with both hardware-native and BSD-compatible implementations.
This is similar to the STM32F7 implementation.
(up_txint): Block enabling TX interrupt if line break in progress.
This is similar to the STM32F7 implementation.
The PIC32MZ architecture provides a Peripheral Pin Select (PPS) which
allows mapping peripherals to different GPIO pins. To map a peripheral
output, a value is programmed to a register called RPnxR, where n is
the GPIO port (A thru K) and x is the GPIO pin (0 thru 15). The names
of these registers in code are PIC32MZ_RPnxR. However, in various
definitions, these were mistakenly written as PI32MZ_RPnxR (missing C
in PIC32). This prevents using any of the affected mappings. This
issue is fixed by repairing the define names.
* arch/mips/src/pic32mz/hardware/pic32mzec_pps.h,
arch/mips/src/pic32mz/hardware/pic32mzef_pps.h:
(): s/PI32MZ/PIC32MZ/g
The defines for Peripheral Pin Select (PPS) register RPE5R were called
RPE4R inadvertently; however, mappings elsewhere in the file used the
correct name of RPE5R, so the build would break if anyone attempted to
map those peripherals to GPIO pin E5. This issue is now fixed.
* arch/mips/src/pic32mz/hardware/pic32mzec_pps.h,
arch/mips/src/pic32mz/hardware/pic32mzef_pps.h:
(PIC32MZ_RPE4R_OFFSET): Rename to PIC32MZ_RPE5R_OFFSET.
(PIC32MZ_RPE4R): Rename to PIC32MZ_RPE5R.
Previously, it was impossible to build for PIC32MZ architecture with
CONFIG_SERIAL_TERMIOS because it introduced compiler errors in the
lower half driver.
Fixing the compiler errors and adding an implementation of the
TIOCSERGSTRUCT, TCGETS, and TCSETS ioctl calls.
* arch/mips/src/pic32mz/pic32mz_serial.c
(): Include nuttx/fs/ioctl.h, needed for the TIOCSERGSTRUCT, TCGETS,
and TCSETS defines.
(up_ioctl): Fix compile breakage. Implement TIOCSERGSTRUCT. Make
TCGETS return data bits, parity, and stop bits. Make TCSETS apply
changes to data bits, parity, and stop bits.
It takes about 10 cycles to obtain the task list according to the task
status. In most cases, we know the task status, so we can directly
add the task from the specified task list to reduce time consuming.

In the past, header file paths were generated by the incdir command
Now they are generated by concatenating environment variables
In this way, when executing makefile, no shell command will be executed,
it will improve the speed of executing makfile
