Adds a platform specific implementation for tickless schedular operation. This includes:
- Tickless operation for vexriscv cores.
- Tickless operation for vexriscv-smp cores.
- Ticked operation for vexriscv-smp cores.
Ticked operation for vexriscv core has been refactored.
Additional default configuration added to demonstrate operation.
Both tickless and ticked options use Litex timer0 for scheduling intervals. This is significantly faster than interfaceing with the risc-v mtimer through opensbi.
Considering kernel code, it's reasonable to use `PANIC()` instead
of `assert(0)` to handle with situations that require abort. Unlike
`assert`, `PANIC()` doesn't dependent on `NDEBUG`.
ESP32-S3 has only one 2.4 GHz ISM band RF module, which is shared
by Bluetooth and Wi-Fi, so Bluetooth can’t receive or transmit data
while Wi-Fi is receiving or transmitting data and vice versa.
Under such circumstances, ESP32-S3 uses the time-division
multiplexing method to receive and transmit packets.
The low-level Wi-Fi driver registers two peripheral interrupts to
the same CPU interrupt. Although the registered ISR is the same for
both peripherals interrupt, it's needed to call `up_enable_irq` to
ensure that the interrupt matrix is being set accordingly.
Please note that the current implementation of the ESP32-S3's IRQ
driver - although allow us to set a callback for each IRQ, which
represents the peripherals interrupt - doesn't allow us to call
both callbacks when these IRQs refers to a same CPU interrupt.
`g_cpu0_intmap` (or `g_cpu1_intmap`) associates each CPU interrupt
to a single IRQ/peripheral and, then, when a CPU interrupt is
triggered, only the last registered IRQ's callback will be called.
This isn't a problem here because 1) the registered callback is the
same for both IRQ's (in fact, it considers the CPU interrupt) and
2) we know in advance which peripheral interrupts will be attached
to which CPU interrupt and, then, we can set them directly.
This prevents us from getting stuck while polling the different
network structures in `devif_poll_connections`. This is useful for
Wi-Fi/Bluetooth coexistence, specifically.
- Fix macro values from `arch/xtensa/include/esp32s3/irq.h`
- Remove references to unexisting edge-triggered CPU interrupts
- Add `esp32s3_getirq` to get IRQ based on core and the `cpuint`
RTC subsystem controls not only the RTC itself but functions that
use RTC-enabled features like Bluetooth and Wi-Fi. Initialization
must be performed during the system start-up.
Adding the CONFIG_ARCH_PERF_EVENTS configuration to enable
hardware performance counting，solve the problem that some platform
hardware counting support is not perfect, you can choose to use
software interface.
This is configured using CONFIG_ARCH_PERF_EVENTS, so weak_functions
are removed to prevent confusion
To use hardware performance counting, must:
1. Configure CONFIG_ARCH_PERF_EVENTS, default selection
2. Call up_perf_init for initialization

If TEE nesting REE breaks, then EXC_RETURN.S=0,EXC_RETURN.ES=1;
Conversely, EXC_RETURN.S=1,EXC_RETURN.ES=0;
Interrupt nesting between TEE and REE can be determined based

Only once nesting between TEE and REE is supported, and cyclic

- Added Wi-Fi related symbols to the kernel-space linker;
- Allocate more RAM to the kernel (to be useb by the Wi-Fi driver).
- Create a specific defconfig.
Instead of setting kernel/user space instruction and data ROM as
hard-coded values on linker, set them according to the max size
of the kernel image set by CONFIG_ESP32S3_KERNEL_IMAGE_SIZE. This
is done by making KIROM, UIROM, KDROM and UDROM dependent on the
kernel size value. Also, override CONFIG_NUTTX_USERSPACE config
according to CONFIG_ESP32S3_KERNEL_IMAGE_SIZE by using a custom

- Save the FPU registers into the tcb so they don't get lost if the stack
frame for xcp.regs moves (as it does)
- Handle interger and FPU register save/load separately
- Integer registers are saved/loaded always, like before
- FPU registers are only saved during a context switch:
- Save ONLY if FPU is dirty
- Restore always if FPU has been used (not in FSTATE_OFF, FSTATE_INIT)
- Remove all lazy-FPU related logic from the macros, it is not needed
Why? The tcb can contain info that is needed by the context switch
routine. One example is lazy-FPU handling; the integer registers can
be stored into the stack, because they are always stored & restored.
Lazy-FPU however needs a non-volatile location to store the FPU registers
as the save feature will skip saving a clean FPU, but the restore must
always restore the FPU registers if the thread uses FPU.
