Summary:
- This commit fixes imx_enet.c if CONFIG_IMX_ENET_NTXBUFFERS=1
- Also adds some ninfo() debug messages
Impact:
- imx_enet.c only
Testing:
- Tested with sabre-6quad:netnsh with QEMU

Summary:
- Since imx_enet.c is based on imxrt_enet.c and still under debugging,
the differences should be minimum to keep tracking the changes
Impact:
- None

The stm32f412 was not a clean port. This is one step to fix
it. The shortcuts taken has caused more wasted hours finding
bad pin mappings then doing the job correctlry to begin with.
stm32:Kconfig Add CAN2 on STM32F412
This bug made certain values of DRIVE setting
to be wrongly applied (which can be dangerous
under certain situations since for example H0D1
was mapped to H0H1).

Summary:
- This commit adds imx_enet driver derived from imxrt_enet
Impact:
- imx6 only
Testing:
- Tested with sabre-6quad:netnsh
- NOTE: telnetd works with QEMU
Summary:
- This commit fixes peripheral IP offsets in AIPS-2
Impact:
- No impact because there is no drivers
Testing:
- Tested with sabre-6quad:nsh and sabre-6quad:smp
Summary:
- During repeating ostest with sabre-6quad:smp (QEMU),
I noticed that pthread_rwlock_test sometimes stops
- Finally, I found that nxtask_exit() released a critical
section too early before context switching which resulted in
selecting inappropriate TCB
- This commit fixes this issue by moving nxsched_resume_scheduler()
from nxtask_exit() to up_exit() and also removing
spin_setbit() and spin_clrbit() from nxtask_exit()
because the caller holds a critical section
- To be consistent with non-SMP cases, the above changes
were done for all CPU architectures
Impact:
- This commit affects all CPU architectures regardless of SMP
Testing:
- Tested with ostest with the following configs
- sabre-6quad:smp (QEMU, dev board), sabre-6quad:nsh (QEMU)
- spresense:wifi_smp
- sim:smp, sim:ostest
- maix-bit:smp (QEMU)
- esp32-devkitc:smp (QEMU)

When the architectural support for STM32G4 family was added, the
reference manual (RM0440) was at revision 2. Since then, it has
undergone several revisions. One significant change is in the
table of FLASH wait states: section 3.3.3 table 9. The outcome
of this change is that fewer FLASH wait states are needed for
most CPU clock (HCLK) frequencies. Notably, if running the CPU
clock at the maximum 170 MHz, only 4 FLASH wait states are
needed, rather than the previously programmed 8 wait states.
This gives a noticeable performance boost.
arch/arm/src/stm32/stm32g4xxxx_rcc.c:
* FLASH_ACR_LATENCY_SETTING: Reimplement compile-time logic
that selects the required wait state setting to use the new
updated table.
* Update all comments to indicate that RM0440 Rev 5 is used.
* Update section numbers mentioned in comments in cases where
they have changed due to added sections in the manual.
arch/arm/src/stm32/hardware/stm32_adc_v2g4.h:
* New file.
arch/arm/src/stm32/hardware/stm32_adc.h:
* Distinguish between the normal STM32 ADC IPv2 core and the
modified IPv2 core used in the G4 family, and include either
stm32_adc_v2.h or stm32_adc_v2g4.h as needed.
Summary:
- This commit introduces SP_WFE() and SP_SEV() to be used for spinlock
- Also, use wfe/sev instructions for ARMV7-A to reduce power consumption
Impact:
- ARMV7-a SMP only
Testing:
- sabre-6quad:smp (QEMU, dev board)
- maix-bit:smp, esp32-devkitc:smp, spresense:smp sim:smp (compile only)

Summary:
- This commit fixes global IRQ control logic
- In previous implementation, g_cpu_irqset for a remote CPU was
set in sched_add_readytorun(), sched_remove_readytorun() and
up_schedule_sigaction()
- In this implementation, they are removed.
- Instead, in the pause handler, call enter_critical_setion()
which will call up_cpu_paused() then acquire g_cpu_irqlock
- So if a new task with irqcount > 1 restarts on the remote CPU,
the CPU will only hold a critical section. Thus, the issue such as
'POSSIBLE FOR TWO CPUs TO HOLD A CRITICAL SECTION' could be resolved.
- Fix nxsched_resume_scheduler() so that it does not call spin_clrbit()
if a CPU does not hold a g_cpu_irqset
- Fix nxtask_exit() so that it acquires g_cpu_irqlock
- Update TODO
Impact:
- All SMP implementations
Testing:
- Tested with smp, ostest with the following configurations
- Tested with spresense:wifi_smp (NCPUS=2,4)
- Tested with sabre-6quad:smp (QEMU, dev board)
- Tested with maix-bit:smp (QEMU)
- Tested with esp32-core:smp (QEMU)
- Tested with lc823450-xgevk:rndis
