[U-Boot-Users] Adding support to M5282Lite

Hi all,
I want port U-Boot to M5282Lite board.

To it create a new target in U-Boot Makefile and create the directory
boards/m5282lite and include/configs/M5282LITE.h based on M5282EVB.

Also added the SDRAM init code to initdram().

These is my main defines:

TEXT_BASE = 0xFFE00000
#define CFG_LOAD_ADDR           0x20000
#define CFG_FLASH_BASE          0xffe00000
#define CFG_MONITOR_BASE        (CFG_INT_FLASH_BASE + 0x400)

Using the m68k-bdm-elf-gdb I am trying to start u-boot:

(gdb) target bdm /dev/bdmcf0
Detected V2 core
GDB target bdm connected to /dev/bdmcf0
 Coldfire debug module version is 0 (5206(e)/5272/5282)

[Switching to process 42000]
0xffe0808a in do_bootm (cmdtp=0xffffffff, flag=-1, argc=-1,
argv=0xffffffff) at cmd_bootm.c:345
345                     printf ("   Uncompressing %s ... ", name);

But it never goes to cpu_init_f ...

Am I doing some misconfiguration or some wrong step?
