1From VxWorks 6.9+ (not include 6.9), VxWorks starts adopting device tree as its hardware 2decription mechansim (for PowerPC and ARM), thus requiring boot interface changes. 3This section will describe the new interface. 4 5For PowerPC, the calling convention of the new VxWorks entry point conforms to the ePAPR standard, 6which is shown below (see ePAPR for more details): 7 8 void (*kernel_entry)(fdt_addr, 9 0, 0, EPAPR_MAGIC, boot_IMA, 0, 0) 10 11For ARM, the calling convention is show below: 12 13 void (*kernel_entry)(void *fdt_addr) 14 15When booting new VxWorks kernel (uImage format), the parameters passed to bootm is like below: 16 17 bootm <kernel image address> - <device tree address> 18 19The do_bootvx command still works as it was for older VxWorks kernels. 20
