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

75 * The ARM boot monitor initializes the board.
76 * However, the default U-Boot code also performs the initialization.
77 * If desired, this can be prevented by defining SKIP_LOWLEVEL_INIT
78 * - see documentation supplied with board for details of how to choose the
79 * image to run at reset/power up
80 * e.g. whether the ARM Boot Monitor runs before U-Boot
82 /* #define CONFIG_SKIP_LOWLEVEL_INIT */
85 * The ARM boot monitor does not relocate U-Boot.
86 * However, the default U-Boot code performs the relocation check,
87 * and may relocate the code if the memory map is changed.
88 * If necessary this can be prevented by defining SKIP_RELOCATE_UBOOT
