23 * ======== Boot ========
24 * Concerto M3 Boot Support.
25 *
26 * The Boot module supports boot initialization for the Concerto M3 core.
27 * A special boot init function is created based on the configuration
28 * settings for this module. This function is hooked into the
29 * xdc.runtime.Reset.fxns[] array and called very early at boot time (prior
30 * to cinit processing).
31 *
32 * The code to support the boot module is placed in a separate section
33 * named `".text:.bootCodeSection"` to allow placement of this section in
34 * the linker .cmd file if necessary. This section is a subsection of the
35 * `".text"` section so this code will be placed into the .text section unless
36 * explicitly placed, either through
37 * `{@link xdc.cfg.Program#sectMap Program.sectMap}` or through a linker
38 * command file.
