cuiziwei 25eb09c3bb nuttx/boards:add KEEP to *(.init_array .init_array.*) 
replace *(.init_array .init_array.*) with KEEP(*(.init_array .init_array.*)).

The KEEP statement within a linker script will instruct the linker to keep the specified section, even if no symbols inside it are referenced. This statement is used within the SECTIONS section of the linker script. This becomes relevant when garbage collection is performed at link time, enabled by passing the --gc-sections switch to the linker. The KEEP statement instructs the linker to use the specified section as a root node when creating a dependency graph, looking for unused sections. Essentially forcing the section to be marked as used.

Nucleo-64 Boards
================

The Nucleo-F334R8 is a member of the Nucleo-64 board family.  The Nucleo-64
is a standard board for use with several STM32 parts in the LQFP64 package.
Variants include

Configurations
==============

  nsh:
  ----

    Configures the NuttShell (nsh) located at apps/examples/nsh.

  adc:
  ----

    Configures the ADC example located at apps/examples/adc.

  highpri:
  --------

    Configures the high priority interrupts example (ADC + PWM)

  spwm1 and spwm2:
  ----------------

    Configures the sinusoidal PWM (SPWM) example which presents a simple use case
    of the STM32 PWM lower-half driver without generic upper-half PWM logic.

    There are two variants of this example, where functionality is achieved with
    different periperals:

      - spwm1 uses HRTIM to generate PWM and change waveform samples
      - spwm2 uses TIM1 to generate PWM and TIM6 to change waveform samples

    At the moment, the waveform parameters are hardcoded, but it should be easy to
    modify this example and make it more functional.
