This patch series depends on the "mach-snapdragon: handle platforms without PSCI support" patch that was submitted earlier today. That first patch lays some groundwork to handle detecting when a device is booting without PSCI and deletes the /psci node in that case.
This series builds on top of that detection by rewriting all CPUs with enable-method="psci" to "spin-table".
Once this is done, the existing spin-table support in U-Boot handles further patching the nodes with the appropriate cpu-release-addr and reserving the memory with the spin-table instructions.
Interestingly, this spin-table code doesn't seem to be in active use anywhere, and it had bitrotted a little. But after blowing the dust off it and fixing a couple of missing #includes, it works great.
I extended the spin-table support a little to make it easier for consumers to plug in a method that is called for each CPU that needs to be brought online. This saves the qcom board code from needing to hook into ft_board_setup or something that runs before booting the OS.
