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.

ARM Trusted Firmware or other firmware.
