Both CPUs are soft-reset with a call to board_reset. This is actually a
Core Reset, so both cores and all registers are reset. The only
exception is RTC.

Endian-ness issues are mind boggling sometimes. I have been confused by the logic in inet_ntop() a few times so I thought I would add some comments so that I (and others) will understand the endian-ness issues in the future. No change to logic, only comments changed.
Summary:
- The handle_irqreq() is used for remote IRQ control.
- The logic is called via IPI (Inter-Processor Interrupt)
- And the handler should handle only one request
- However, I noticed that the handler handles up to two requests
- This commit fixes this issue
Impact:
- Affects SMP cases only
Testing:
- Tested with spresense:wifi_smp

Not all boards have an interrupt line from the phy to
the Soc. This commit allows the phy to be polled for
link status.
This may not work on all MAC/PHY combination that
have mutually exclusive link management and operating
modes. The STM32F7 and LAN8742AI do not have such a
limitation.
Summary:
- I noticed that stack for the init task was filled almost 100%
- This commit fixes this issue
Impact:
- Affects spresense:wifi configuration only
Testing:
- Tested with renew/mount/wget/nxplayer commands

When executing an MRET instruction, MIE is set to MPIE.
In order to branch to up_sigdeliver() with interrupts disabled,
we need to change MPIE, not MIE.
