On Armv8-R, the EL1&0 memory system architecture is configurable as a VMSA or PMSA, and resets to an "architecturally unknown" value. Add code to armv8_switch_to_el1_m which detects whether the MSA at EL1&0 is configurable using the id_aa64mmfr0_el1 register MSA fields. If it is we must ensure the VMSA is enabled so that a rich OS can boot. The MSA and MSA_FRAC fields are described in the Armv8-R architecture profile supplement (section G1.3.7): https://developer.arm.com/documentation/ddi0600/latest/ Signed-off-by: Peter Hoyes <Peter.Hoyes@arm.com> |
