 * Name: stm32_romfs_initialize
 *
 * Description:
 *   Registers built-in ROMFS image as block device and mounts it.
 *
 * Returned Value:
 *   Zero (OK) on success, a negated errno value on error.
 *
 * Assumptions/Limitations:
 *   Memory addresses [romfs_data_begin .. romfs_data_end) should contain
 *   ROMFS volume data, as included in the assembly snippet above (l. 84).
