Alexey Brodkin 8b2eb776b1 arc: implement slave cores kick-start for Linux kernel ... With new SMP-enabled CPUs with ARC HS38 cores and corresponding support in Linux kernel it's required to add basic SMP support in U-Boot. Currently we assume the one and only core starts execution after power-on. So most of things in U-Boot is handled in UP mode. But when U-Boot is used for loading and starting Linux kernel right before jumping to kernel's entry point U-Boot: [1] Sets all slave cores to jump to the same address [kernel's entry point] [2] Really starts all slav cores In ARC's implemetation of SMP in Linux kernel all cores are supposed to run the same start-up code. But only core with ID 0 (master core) processes further while others are looping waiting for master core to complete some initialization. That means it's safe to un-pause slave cores and let them execute kernel - they will wait for master anyway.
