The next version VxWorks adopts device tree (for PowerPC and ARM) as its hardware
description mechanism. For PowerPC, the boot interface conforms to
the ePAPR standard, which is:
void (*kernel_entry)(ulong fdt_addr,
ulong r4 /* 0 */,
ulong r5 /* 0 */,
ulong r6 /* EPAPR_MAGIC */, ulong r7 /* IMA size */,
ulong r8 /* 0 */, ulong r9 /* 0 */)
For ARM, the boot interface is:
void (*kernel_entry)(void *fdt_addr)
