The related code is below (maybe we need add additional related
comments in the patch for it ?).

in arch/h8300/kernel/setup.c

 94 void __init setup_arch(char **cmdline_p)
 95 {
 96         int bootmap_size;
 97 
 98         memory_start = (unsigned long) &_ramstart;
 99 
100         /* allow for ROMFS on the end of the kernel */
101         if (memcmp((void *)memory_start, "-rom1fs-", 8) == 0) {
102 #if defined(CONFIG_BLK_DEV_INITRD)
103                 initrd_start = memory_start;
104                 initrd_end = memory_start += be32_to_cpu(((unsigned long *) (memory_start))[2]);
105 #else
106                 memory_start += be32_to_cpu(((unsigned long *) memory_start)[2]);
107 #endif
108         }
