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