dad5a79bf3 arch: arm: Fix interrupt stack handlings for SMP
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)

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

0d971d4673 arch: cxd56xx: Fix IRQ control in cxd56_dmac.c
Summary:
- This commit fixes IRQ control for the following use case
- The gs2200m Wi-Fi driver requests SPI-DMA to receive a packet.
- cxd56_dma.c enables IRQ for the SPI-DMA and start transfer.
- Then LCD driver requests SPI-DMA to display an image.
- These SPI-DMAs use different DMA channels but share the DMA controller.
- Also, they share the same IRQ.
- When the first SPI-DMA finishes the transfer, it disables the IRQ.
- And if the second SPI-DMA finishes the transfer just after the IRQ disabled.
- The second SPI-DMA will be in a deadlock condition.
- To resolve this issue, do not control IRQ during DMA transfer.
- Instead, up_enable_irq() is called in up_dma_initialize()

Impact:
- All use cases which use DMA

Testing:
- Tested with spresense:wifi with LCD

Summary

The naming standard at https://cwiki.apache.org/confluence/display/NUTTX/Naming+FAQ requires that all MCU-private functions begin with the name of the architecture, not up_.

This PR addresses function-like macro naming that was missing in previous PRs:  up_savestate() and up_restorestate() which must be named arm_savestate() and arm_restorestate().

Impact

There should be no impact of this change (other that one step toward more consistent naming).

Summary

The naming standard at https://cwiki.apache.org/confluence/display/NUTTX/Naming+FAQ requires that all MCU-private functions begin with the name of the architecture, not up_.

This PR addresses only these name changes for the ARM-private functions prototyped in arm_internal.h

This change to the files only modifies the name of called functions.  nxstyle fixes were made for all core architecture files.  However, there are well over 5000 additional complaints from MCU drivers and board logic that are unrelated to to this change but were affected by the name change.  It is not humanly possible to fix all of these.   I ask that this change be treated like other cosmetic changes that we have done which do not require full nxstyle compliance.

Impact

There should be not impact of this change (other that one step toward more consistent naming).

    up_arch.h
    up_internal.h
    up_vfork.h

The only change to the files is from including up_arch.h to arm_arch.h (for example).

The entire job required to be compatible with that Naming Convention will also require changing the naming of the up_() functions that are used only within arch/arm and board/arm.

72104c182c nxstyle fixes
Run all files modified by PR 766 through nxstyle and fix any resulting complaints.

NOTE:  Numerous "Mixed case identifier" errors in arch/arm/src/cxd56xx/cxd56_gnss.c were not fixed because this problem is of much larger scope than this file.

67ec3d7926 Remove CONFIG_CAN_PASS_STRUCT
This commit resolves issue #620:

Remove CONFIG_CAN_PASS_STRUCTS #620

The configuration option CONFIG_CAN_PASS_STRUCTS was added many years ago to support an old version of the SDCC compiler. That compiler is currently used only with the Z80 and Z180 targets. The limitation of that old compiler was that it could not pass structures or unions as either inputs or outputs. For example:

    #ifdef CONFIG_CAN_PASS_STRUCTS
    struct mallinfo mallinfo(void);
    #else
    int      mallinfo(FAR struct mallinfo *info);
    #endif

And even leads to violation of a few POSIX interfaces like:

    #ifdef CONFIG_CAN_PASS_STRUCTS
    int  sigqueue(int pid, int signo, union sigval value);
    #else
    int  sigqueue(int pid, int signo, FAR void *sival_ptr);
    #endif

This breaks the 1st INVIOLABLES rule:

Strict POSIX compliance
-----------------------

  o Strict conformance to the portable standard OS interface as defined at
    OpenGroup.org.
  o A deeply embedded system requires some special support.  Special
    support must be minimized.
  o The portable interface must never be compromised only for the sake of
    expediency.
  o Expediency or even improved performance are not justifications for
   violation of the strict POSIX interface

Also, it appears that the current SDCC compilers have resolve this issue and so, perhaps, this is no longer a problem: z88dk/z88dk#1132

NOTE:  This commit cannot pass the PR checks because it depends on matching changes to the apps/ directory.
