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.

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

  ihm07m1_b16:
  ------------

    These examples are dedicated for the X-NUCLEO-IHM07M1 expansion board
    based on L6230 DMOS driver for three-phase brushless DC motors.

    X-NUCLEO-IHM07M1 must be configured to work with FOC and 3-shunt
    resistors. See ST documentation for details.

    Pin configuration for the X-NUCLEO-IHM07M1 (TIM1 configuration):
