Hi Maxime, This patchset adds in the necessary code to manage the holding pen for STi platforms. Due to all the STi upstream devs using JTAG to boot the STi boards, there is currently a SMP bug when booting upstream kernels via u-boot where only the primary core is brought up. This hasn't been noticed until now because when booting via JTAG the stlinux_arm_boot script sets the PC of the secondary cores directly. I can't test this on a STiH418 platform, as I don't have one, but a similar DT change will be required there as well. I'm not sure if u-boot uses the same SBC DMEM offset by default or not. With these patches applied booting via u-boot now works correctly.
