25 * There are various dependencies on the core module (CM) fitted
26 * Users should refer to their CM user guide
28 #include "armcoremodule.h"
31 * Initialize and remap the core module, use SPD to detect memory size
32 * If CONFIG_SKIP_LOWLEVEL_INIT is not defined &
33 * the core module has a CM_INIT register
34 * then the U-Boot initialisation code will
35 * e.g. ARM Boot Monitor or pre-loader is repeated once
36 * (to re-initialise any existing CM_INIT settings to safe values).
38 * This is usually not the desired behaviour since the platform
39 * will either reboot into the ARM monitor (or pre-loader)
40 * or continuously cycle thru it without U-Boot running,
41 * depending upon the setting of Integrator/CP switch S2-4.
43 * However it may be needed if Integrator/CP switch S2-1
44 * is set OFF to boot direct into U-Boot.
45 * In that case comment out the line below.

52 * The ARM boot monitor initializes the board.
53 * However, the default U-Boot code also performs the initialization.
54 * If desired, this can be prevented by defining SKIP_LOWLEVEL_INIT
55 * - see documentation supplied with board for details of how to choose the
56 * image to run at reset/power up
57 * e.g. whether the ARM Boot Monitor runs before U-Boot
59 /* #define CONFIG_SKIP_LOWLEVEL_INIT */
62 * The ARM boot monitor does not relocate U-Boot.
63 * However, the default U-Boot code performs the relocation check,
64 * and may relocate the code if the memory map is changed.
65 * If necessary this can be prevented by defining SKIP_RELOCATE_UBOOT
