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

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