TX clock or ref clock can be driven either from outside (PHY / oscilator) or by the ENET block.
Typical connection with RMII PHY is that the PHY drives the refclk.

New configuration IMX9_HAVE_ATF_FIRMWARE introduced,
it is default on and it selects ARM64_HAVE_PSCI, when compiling
bootloader or when using bootloader that does not have atf

Using the HLT instruction in VM usually traps into the Hypervisor and releases CPU control. This will result in real-time performance degradation. Using the NOP or MWAIT instruction for an IDLE loop can reduce energy consumption while not trapping into the Hypervisor.

Clean up the interrupt-driven logic in the driver; handle error cases properly,
remove dead code and simplify logic.

Change "DMACH_HANDLE *handle" into "DMACH_HANDLE handle". The DMACH_HANDLE is already
defined as "void *".

currently esp32 protected mode requires a patched bootloader.
it's a bit cumbersome to build the bootloader for that purpose.
this commit attempts to remove the need of the patched bootloader
by applying the changes by ourselves using esp hal.
Using the ts/tick conversion functions provided in clock.h
Do this caused we want speed up the time calculation, so change:
clock_time2ticks, clock_ticks2time, clock_timespec_add,
clock_timespec_compare, clock_timespec_subtract... to MACRO

Enforcing the default 48-bit VA for everyone also implies a 4 page table
translation system. However, if less than 40 bits are needed, a full
translation table level can be dropped, making the translations faster.
Thus, make this into a configurable option, instead of enforcing the same
address widht for everyone.
Attempt to service all interrupts pending in the PLIC's claim register. Ideally, this is more efficient than switching context for each interrupt received.
Provides two implementations:
- CSR_CYCLE: Cores which implement hardware performance monitoring.
- CSR_TIME: Uses the machine time registers.
Using the up_perf_xx bindings directory is more efficient than performing a nanosecond conversion on every gettime event.
There is a tiny possibility that when a process is started a trap is
taken which causes a context switch. This moves the kernel stack
unexpectedly and the task start logic no longer works.
Fix this by recording the initial context location, and use that to
trampoline into the user process with interrupts disabled. This ensures
the context stays intact AND the kernel stack is fully unwound before
the user process starts.
This patch unifies the extended context save/restore for RISC-V,
allowing the customized context save/restore to be used, for example,
the extended context in rv32m1.

The register context is not needed, the original idea was to provide
the user stack pointer for signal handler delivery, but the user stack
can be obtained via sp_el0 so the context registers are not needed.
SP0 is not stored upon exception entry anyways, so this code is just
completely redundant and wrong.
reason:
In SMP, when a context switch occurs, restore_critical_section is executed.
To reduce the time taken for context switching, we directly pass the required
parameters to restore_critical_section instead of acquiring them repeatedly.

The vaddr field in TLBI means: Bits[55:12] of the virtual address to match.
This basically means the page offset of the virtual address, so the input
vaddr must be shifted to the page offset.
Reference TLBI VALE1IS register description from ARMv8-A reference manual.
The 12:0 bits in table descriptors are RES0 and AF is the 10th bit, so
it is not valid to set it in this case.
Fix this by moving AF to the common MMU_MT_NORMAL_FLAGS field
Make sure the user L1 page is updated to system memory when the kernel
mappings are copied.
Also, flush the I-cache when switching address environments.
The libmad and libmp3lame libraries have been ported to
apps/audioutils and will be compiled with NuttX.

Since the introduction of the rp2350, the pico-sdk project has been
re-arranged and elf2uf2 has been merged in to a new 'picotool' binary
which is supplied and installed separately.
