. This structure is defined in the BootX project in the file boot_args.h .struct boot_args {
unsigned short Revision; /* Revision of boot_args structure */
unsigned short Version; /* Version of boot_args structure */
char CommandLine[BOOT_LINE_LENGTH]; /* Passed in command line */
DRAMBank PhysicalDRAM[kMaxDRAMBanks]; /* base/range pairs for the 26 DRAM banks */
Boot_Video Video; /* Video Information */
unsigned long machineType; /* Machine Type (gestalt) */
void *deviceTreeP; /* Base of flattened device tree */
unsigned long deviceTreeLength; /* Length of flattened tree */
unsigned long topOfKernelData; /* Last address of kernel data area*/
};
