The NXP ls1043 and ls1046 systems do not (yet) have PSCI enablement for reset. Don't enable generic PSCI reset code on them. Signed-off-by: Alexander Graf <agraf@suse.de>

Say Y here to support "spin-table" enable method for booting Linux.
|
|
|
|
To use this feature, you must do:
|
|
- Specify enable-method = "spin-table" in each CPU node in the
|
|
Device Tree you are using to boot the kernel
|
|
- Let secondary CPUs in U-Boot (in a board specific manner)
|
|
before the master CPU jumps to the kernel
|
|
|
|
U-Boot automatically does:
|
|
- Set "cpu-release-addr" property of each CPU node
|
|
(overwrites it if already exists).
|
|
- Reserve the code for the spin-table and the release address
|
|
via a /memreserve/ region in the Device Tree.

Most armv8 systems have PSCI support enabled in EL3, either through
|
|
ARM Trusted Firmware or other firmware.
|
|
|
|
On these systems, we do not need to implement system reset manually,
|
|
but can instead rely on higher level firmware to deal with it.

|
Select Y here to make use of PSCI calls for system reset
