Invalidate the Branch Target Buffer (BTB) on entry to EL3 by disabling and enabling the MMU. To achieve this without performing any branch instruction, a per-cpu vbar is installed which executes the workaround and then branches off to the corresponding vector entry in the main vector table. A side effect of this change is that the main vbar is configured before any reset handling. This is to allow the per-cpu reset function to override the vbar setting. This workaround is enabled by default on the affected CPUs. Change-Id: I97788d38463a5840a410e3cea85ed297a1678265 Signed-off-by: Dimitris Papastamos <dimitris.papastamos@arm.com> |
