+
+ For A53, it enables data coherency with other cores in the

+ 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.

config ARMV8_SPIN_TABLE
bool "Support spin-table enable method"
depends on ARMV8_MULTIENTRY && OF_LIBFDT
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
+ - 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
- Reserve the code for the spin-table and the release address
via a /memreserve/ region in the Device Tree.
