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

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