2925c28f8f All linker scripts: Preface all _edata defininitions with . = ALIGN(4). Otherwise, the last bytes in the .data section may not be initialized properly. Also convert all linker scripts indent in units of 8-spaces to units of 4-spaces. 2019-09-15 17:22:16 -06:00

507e01cb8e This commit adds support for the NXP S32K148EVB
Squashed commit of the following:

    boards/arm/s32k1xx/s32k148evb:  Correct linker scripts for the S32K148, Update README files, Hook eht S32K148EVB into the configuration and build system.

    arm/s32k1xx/s32k148evb:  Verify core and peripheral clocking.  It is the same as the S32K146EVB.  Fixed one-too-many copy-paste error in both.

    boards/arm/s32k1xx/s32k148evb:  Correct LED and button pin number for the S32K148EVB.

    boards/arm/s32k1xx/s32k148evb:  Change all occurrences of 146 to 148.

    boards/arm/s32k1xx/s32k148evb:  Initial S32K148EVB.  Initial commit is just  clone of S32K146EVB with file name changes

c6026d7500 With these changes the S32K146EVB minimal NSH is function. Only verifed while running from SRAM.
arch/arm/src/s32k1xx/s32k1xx_lowputc.c:  Fix a typo that prevented LPUART1 from working.
    arch/arm/src/s32k1xx/s32k1xx_periphclocks.c and related files:  Fix yet another case of confusion between pre-decremented and non-decremented divider values.  Enforce the rule that dividers are not decremented until the moment they are written into registers.
    arch/arm/src/s32k1xx/s32k1xx_clockconfig.c:  Fix another problem related to whether a divider is pre-decremented or not.  The answer must be the divder values are never pre-decremented.  They are decremented just before being written to hardware.
    arch/arm/src/s32k1xx/s32k1xx_clockconfig.c:  Clean up some bad conditional logic.  Precedence of operators problem.
    boards/arm/s32k1xx/s32k118evb:  Add support for execution out of SRAM.  This is helpful for bringup when you want to avoid putting a lethal image in FLASH.
    arch/arm/src/s32k1xx/s32k1xx_clockconfig.h:  Remove crystal frequency, it is not used.
    arch/arm/src/s32k1xx/s32k1xx_wdog.h:  Fix a typo in a register name.i
    boards/arm/s32k1xx/s32k*evb/configs/nsh/defconfig:  Create Motorola SREC output format.

    s32k1xx/s32k146evb/scripts/flash.ld:  Update the linker script for the S32K146.
    boards/:  Hook the S32K146EVB into the configuration and build system.
    s32k146_clockconfig.c:  Add S32K146 clock configuration.
    boards/arm/s32k1xx/s32k146evb/src/s32k146_periphclocks.c:  Update peripheral clocking for the S32K146.
    arm/s32k1xx/s32k146evb:  Initial support fo S32K146EVB.  Starting point is just the S32K118EVB with name changes.
