On boot we don't need to perform any CPU cache management when the IDC and DIC fields in the ctr_el0 register are set. Add a command to tell loader to ignore these fields. This could be useful, for example, if the hardware is misreporting the values and we are missing a quirk to enable it. It is not expected this will be needed, but is only intended as a workaround to ensure the kernel can still boot. Sponsored by: The FreeBSD Foundation |
