For A53, it enables data coherency with other cores in the
|
|
cluster, and for A57/A72, it enables receiving of instruction
|
|
cache and TLB maintenance operations.
|
|
Cortex A53/57/72 cores require CPUECTLR_EL1.SMPEN set even
|
|
for single core systems. Unfortunately write access to this
|
|
register may be controlled by EL3/EL2 firmware. To be more
|
|
precise, by default (if there is EL2/EL3 firmware running)
|
|
this register is RO for NS EL1.
|
|
This switch can be used to avoid writing to CPUECTLR_EL1,
|
|
it can be safely enabled when EL2/EL3 initialized SMPEN bit
|
|
or when CPU implementation doesn't include that register.

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
|
|
- Bring secondary CPUs into U-Boot proper in a board specific
|
|
manner. This must be done *after* relocation. Otherwise, the
|
|
secondary CPUs will spin in unprotected memory area because the
|
|
master CPU protects the relocated spin code.
|
|
|
|
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.
