Bootloader detection

Hello, All!
Is there a reliable way to detect a SDG bootloader in a way is it done
for Windows Mobile?

        i = 0x000414dc / 4;
        if (bootldr[i] == 0xe59f1360 && /* ldr r1, [pc, #864] ; power base */
            bootldr[i+1] == 0xe5914008 && /* ldr r4, [r1, #8] ; PSPR */
            bootldr[i+2] == 0xe1320004) { /* teq r2, r4 */
                
                printk("Stock HTC WM2003 bootloader detected\n");
                htc_bootloader = 1;
                pxa_pm_set_ll_ops(&hx4700_ll_pm_ops);
        }

Thanks in advance.
