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