Linux stopped the use of keyword 'boolean' in Kconfig.
Refer to commit 6341e62b212a2541efb0160c470e90bd226d5496 ("kconfig:
use bool instead of boolean for type definition attributes")
in Linux Kernel.

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.
