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

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