This PR adds the driver for Xingbangda XBD599 LCD Panel (based on Sitronix ST7703 LCD Controller) on PINE64 PinePhone. This PR also includes:
- The driver for X-Powers AXP803 Power Mgmt IC, which calls our driver for Allwinner A64's Reduced Serial Bus. The PMIC Driver is needed to power on the MIPI DSI Interface for the LCD Panel.
- A simple Display Driver that renders a Test Pattern on the LCD Display at startup. It calls our Allwinner A64 drivers for Display Engine, Timing Controller TCON0 and MIPI Display Serial Interface.
The NuttX Frame Buffer Driver will be implemented in the next PR.
`arch/arm64/src/a64/a64_de.c`, `a64_de.h`: Changed the Frame Buffer pointer to `const` for Allwinner A64 Display Engine
`arch/arm64/src/a64/hardware/a64_memorymap.h`: Added the Base Address for PWM, for controlling the PWM Backlight
`boards/arm64/a64/pinephone/src/pinephone_bringup.c`: Call `fb_register()` to start the Display Driver at startup
`boards/arm64/a64/pinephone/src/Makefile`: Added LCD Driver, PMIC Driver and Display Driver to Makefile
`boards/arm64/a64/pinephone/Kconfig`: Added the Kconfig option for "PINE64 PinePhone > LCD Display" (`CONFIG_PINEPHONE_LCD`) which enables the LCD Driver, PMIC Driver and Display Driver
`boards/arm64/a64/pinephone/src/pinephone_lcd.c`, `pinephone_lcd.h`: Driver for Xingbangda XBD599 LCD Panel
`boards/arm64/a64/pinephone/src/pinephone_pmic.c`, `pinephone_pmic.h`: Driver for X-Powers AXP803 Power Mgmt IC
`boards/arm64/a64/pinephone/src/pinephone_display.c`: Simple Display Driver that renders a Test Pattern in `up_fbinitialize()`
`boards/arm64/a64/pinephone/configs/lcd/defconfig`: New PinePhone Board Configuration `pinephone:lcd` that enables the LCD Driver (`CONFIG_PINEPHONE_LCD`)
`platforms/arm/a64/boards/pinephone/index.rst`: Added PinePhone Board Configuration `pinephone:lcd` that enables the LCD Driver
Summary:
- I noticed that rv-virt:ksmp64 sometimes stops during boot.
- Finally, I found that it posts the Supervisor Software Interrupt
before the OS finishes hardware initialization.
- This commit fixes this issue.
Impact:
- None
Testing:
- Tested with QEMU-7.1

When ipv4_input/ipv6_input called by devif_loopback writes wrong data into buffer (another bug we're fixing), the else block does nothing but only record the 'dropped' statistic, then infinite loop happens.
Refers to previous lo device with dropping logic:

- Adds support for the Starcat Jupiter Nano
SAMA5D27C-LD1G board
- https://github.com/starcat-io/jupiter-nano
- this board is very similar to the Microchip/Atmel
SAMA5D2-Xplained board (sama5d2-xult)
This PR adds the driver for Reduced Serial Bus (RSB) on Allwinner A64 SoC. The RSB Driver will be called by the upcoming Power Mgmt IC Driver for PINE64 PinePhone, to power on the LCD Display.
`arch/arm64/src/a64/Kconfig`: Added the Kconfig option for "A64 Peripheral Selection > RSB" (`CONFIG_A64_RSB`), which enables the RSB Driver
`arch/arm64/src/a64/hardware/a64_memorymap.h`: Added the Base Address for RSB
`arch/arm64/src/a64/Make.defs`: Added the RSB Driver to the Makefile
`arch/arm64/src/a64/a64_de.c`: Increase PLL Timeout for Allwinner A64 Display Engine
`boards/arm64/a64/pinephone/configs/nsh/defconfig`: Set PinePhone Board Config `CONFIG_BOARD_LOOPSPERMSEC` to the value computed by `calib_udelay`
`arch/arm64/src/a64/a64_rsb.c`, `a64_rsb.h`: RSB Driver for Allwinner A64
`platforms/arm/a64/boards/pinephone/index.rst`: Added RSB as supported peripheral for PinePhone
_assert is a kernel procedure, entered via system call to make the core
dump in privileged mode.
Running exit() from this context is not OK as it runs the registered
exit functions and flushes streams, which must not be done
from privileged mode as it is a security hole.
Thus, implement assert() into user space (again) and remove the exit()
call from the kernel procedure.
Instantiate the correct address environment when reading the process's
argument vector. Otherwise doing this will crash the system every time,
causing a recursive assert loop.
Also try to do a bit of sanity checking before attempting to read the
process's memory, it might be in a bad state in which case this will
fail anyway.
I don't know how to handle this properly as I don't know what this
symbol table is supposed to do. Most likely the part that uses the
symbol table needs to be patched also...
This is preparation for flushing streams from user space, like it should
be done.
- Move tg_streamlist (group, kernel space) ->
ta_streamlist (TLS, user space)
- Access stream list via tg_info in kernel
- Access stream list via TLS in user space
- Remove / rename nxsched_get_streams -> lib_getstreams
- Remove system call for nxsched_get_streams
