Summary:
- Modify arm_intstack_base() to return "top" of the IRQ stack for the current CPU
- This change fixes IRQ stack dump information for ARM SMP
- Add arm_intstack_alloc() to return "bottom" of the IRQ stack for the current CPU
- Also, these functions are now implemented in xxx_irq.c (imx/cxd56/lc823450)
- up_color_intstack() and up_check_intstack() now call arm_intstack_alloc()
- These semantics are now consistent with non-SMP case
- up_color_intstack() now initializes whole IRQ stack region for SMP
- Adjust IRQ stack top address for each CPU (e.g. -8)
- Fix setintstack to handle in case of NCPUS=1 (cxd56, lc823450)
- Adjust INTSTACK_SIZE to 8 bytes alignment (cxd56, lc823450)
- Refactor setintstack for lc823450
- Remove old IRQ stack coloring code from up_irqinitialize() (lc823450)
- Introduce g_cpu_intstack_top for lc823450
- Refactor header files
Impact:
- Affects imx6/cxd56xx/lc823450 SMP with interrupt stack enabled
Testing:
- Tested with sabre-6quad:smp (with QEMU, NCPUS=1 and 4)
- Tested with spresense:wifi_smp (NCPUS=1 and 2)
- Tested with lc823450-xgevk:rndis (NCPUS=1 and 2)

cfsetispeed() now stores baud rate to c_cflag member of
struct termios, so it must not be overridden later on.

1.Get the stack pointer from sp instead of .Lstkinit's field
2.Make g_idle_topstack point to the end of the idle stack

arch/arm/src/tiva/cc13xx/cc13x2_cc26x2_v2_rom.h:
* Fix nxstyle errors; nxstyle was complaining about lack of a
space after comma because of the presence of line
continuation backslashes immediately after the comma.
Removed these backslashes as they are not necessary: these
lines are typedefs, not preprocessor defines.
arch/arm/src/tiva/cc13xx/cc13x2_v2_trim.c:
* Fix nxstyle errors.
* No functional changes; however modified one function,
trim_wakeup_fromshutdown(), to avoid blocks that existed
only to declare variables mid-function; nxstyle was
complaining about the positions of the opening and
closing braces of those blocks.
Summary:
- During Wi-Fi audio streaming test, I noticed data corruption in tcb
- Finally, I found an issue in IRQ request handing with IPI
- This commit fixes this issue
Impact:
- Affects SMP only
Testing:
- Tested with spresense:wifi_smp

Summary:
- This commit adds interrupt stack for SMP
Impact:

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 found an issue with up_interrupt_context() when testing.
- And finally found that up_interrupt_context() is not atomic.
- This commit fixes the issue
Impact:
- Affects SMP only
Testing:
- Tested with spresense:wifi_smp and sabre-6quad:smp (qemu)
