Ivan Ucherdzhiev cf8c25df64 This commit brings in basic support fo the i.MX RT 1050 'crossover' SoC. The basic support is complete and compiles without error, but is still untested.
This port was the joing effort of Janne Rosberg, Ivan Ucherdzhiev, and myself.  I give credit to Ivan for the kill because he is the one to held on to the end.

Squashed commit of the following:

  Author: Gregory Nutt <gnutt@nuttx.org>
    configs/imxrt1050-evk/scripts:  Add section to linker script to handle the case where RAMFUNCs are enabled.  RAMFUNCs appear to be enabled in the default configuration ... they probably should not be enabled.

  Author: Ivan Ucherdzhiev <ivanucherdjiev@gmail.com>
    arch/arm/src/imxrt:  imxrt_lowputc.c is finished. Now everything needed for the initial port is done and ready for testing.
    arch/arm/src/imxrt:  Add logic to imxrt_lowputc.c.  Still incomplete.

  Author: Ivan Ucherdzhiev <ivanucherdjiev@gmail.com>
    arch/arm/src/imxrt:  Add serial support.  configs/imxrt1050-evk:  Add linker script.

  Author: Gregory Nutt <gnutt@nuttx.org>
    arch/arm/src/imxrt:  Add initial cut at imxrt_allocateheap.c

  Author: Ivan Ucherdzhiev <ivanucherdjiev@gmail.com>
    arm/arm/src/imxrt:  Completes all definitions for PADMUX, CTLMUX, and IOMUX_INPUT and mapping tables on imxrt_gpio.c and imxr_iomuxc.c.
    arch/arm/src/imxrt/chip:  Add definitions for IMXRT_PADCTL and IMXRT_PADMUX registers.  Only the IMXRT_INPUT definitions in this commit.
    arch/arm/src/imxrt/chip:  Add more IOMUXC register definitions.

  Author: Gregory Nutt <gnutt@nuttx.org>
    configs/imxrt1050-evk:  Add STRIP definition to Make.defs.
    arch/arm/src/imxrt:  Bring in i.MX6 memory configuration settings.
    arch/arm/src/imxrt:  Remove call to non-existent imxrt_gpioinit() from imxrt_start.c.
    arch/arm/src/imxrt:  Bring in incomplete imxrt_iomuxc.c file from i.mx6.
    arch/arm/src/imxrt:  Add first cut at GPIO interrupt logic.
    arch/arm/include:  Add definitions to support a second level of GPIO pin interrupts.

  Author: Janne Rosberg <janne.rosberg@offcode.fi>
    arch/arm/src/imxrt:  Add imxrt_wdog.c/.h

  Author: Gregory Nutt <gnutt@nuttx.org>
    arch/arm/src/imxrt:  Port SAMv7 interrupt logic to imxrt_irq.c.
    arch/arm/src/imxrt:  More clarification of the start-up memory map.
    arch/arm/src/imxrt:  Some mostly cosmetic clean-up to the imxrt_start.c file that was so rudely taken from the SAMv7.
    arch/arm/src/imxrt:  Add imxrt_start.c.  Initial commit is the the SAMv7 startup logic with name changes.

  Author: Ivan Ucherdzhiev <ivanucherdjiev@gmail.com>
    arch/arm/src/imxrt:  Adds a few IOMUXC register definitions.

  Author: Janne Rosberg <janne.rosberg@offcode.fi>
    arch/arm/src/imxrt:  Add imxrt_clockconfig.c/.h
    configs/imxrt1050-evk:  Add clock configuration definitions to board.h
    arch/arm/src/imxrt:  Fix CCM register name; Fix doubly defined in LPUART bit field.
    arch/arm/src/imxrt:  Add analog defines to CCM register definition header file.

  Author: Gregory Nutt <gnutt@nuttx.org>
    arch/arm/src/imxrt:  Bring in GPIO C files from i.MX6.  Things are in disarray now because that GPIO logic depends on IOMUXC logic which is not yet in place.
    arch/arm/src/imxrt:  Add a few more GPIO definitions to make the header file compatible with i.MX6
    arch/arm/src/imxrt/chip:  Add GPIO register definition file.

  Author: Gregory Nutt <gnutt@nuttx.org>
    Purely cosmetic

    Embarassingly trivial change left in compiler.
    arch/arm/src/imxrt:  Finishes i.MX RT1050 LPUART register definition header file.
    arch/arm/src/imxrt:  Beginning of an i.MX RT1050 LPUART register definition header file.
    Some trivial things

  Author: Janne Rosberg <janne.rosberg@offcode.fi>
    arch/arm/src/imxrt:  Add imxrt_wdog.h
    arch/arm/src/imxrt:  Add initial imxrt_ccm.h

  Author: Gregory Nutt <gnutt@nuttx.org>
    Trivial update to README.
    arch/arm/src/imxrt:  The i.MX Rt implements 4 bits of interrupt priority, not two.  Thanks, Janne.
    arch/arm/src/imxrt:  Fix some initial compile issues.  Still a long way from complete, but there is a buildable environment now for the imxrt1050-evk.
    configs/imxrt1050-evk:  Add an initial NSH configuration for testing.
    configs/Kconfig:  Hook the i.MX RT 1050 board configuration into the NuttX configuration system.
    configs/imxrt_evk:  Add the framework for i.MX RT 1050 board support.
    arch/arm/src/imxrt:  Bring in a few more files from LPC54xxx.
    arch/arm/src/imxrt:  Bring in imxrt_clrpend() from the LPC54xxx.
    arch/arm/src/imxrt:  Bring in Cortex-M7 SysTick setup from the SAMv7.
    arch/arm/src/imxrt:  Add a few easy files.
    arch/arm/src/imxrt/chip:  Add memory map header files.
    arch/arm/src/imxrt:  A few basic files to start the port to the i.MX RT 1050.

/* If CONFIG_ARMV7M_USEBASEPRI is selected, then interrupts will be disabled
* by setting the BASEPRI register to NVIC_SYSH_DISABLE_PRIORITY so that most
* interrupts will not have execution priority. SVCall must have execution
* priority in all cases.
*
* In the normal cases, interrupts are not nest-able and all interrupts run
* at an execution priority between NVIC_SYSH_PRIORITY_MIN and
* NVIC_SYSH_PRIORITY_MAX (with NVIC_SYSH_PRIORITY_MAX reserved for SVCall).
*
* If, in addition, CONFIG_ARCH_HIPRI_INTERRUPT is defined, then special
* high priority interrupts are supported. These are not "nested" in the
* normal sense of the word. These high priority interrupts can interrupt
* normal processing but execute outside of OS (although they can "get back
* into the game" via a PendSV interrupt).
*
* In the normal course of things, interrupts must occasionally be disabled
* using the up_irq_save() inline function to prevent contention in use of
* resources that may be shared between interrupt level and non-interrupt
* level logic. Now the question arises, if CONFIG_ARCH_HIPRI_INTERRUPT,
* do we disable all interrupts (except SVCall), or do we only disable the
* "normal" interrupts. Since the high priority interrupts cannot interact
* with the OS, you may want to permit the high priority interrupts even if
* interrupts are disabled. The setting CONFIG_ARCH_INT_DISABLEALL can be
* used to select either behavior:
*
* ----------------------------+--------------+----------------------------
* CONFIG_ARCH_HIPRI_INTERRUPT | NO | YES
* ----------------------------+--------------+--------------+-------------
* CONFIG_ARCH_INT_DISABLEALL | N/A | YES | NO
* ----------------------------+--------------+--------------+-------------

* Disable here and below --------> MAXNORMAL ---> HIGH --------> MAXNORMAL
