I've left removing it for an additional patch for another day. - Added psci_invoke_none() to use prior to the PSCI method being set - Added r-b's for each patch given, unless the commit changed too much - Didn't take Alex's suggestion to use x5 for stacktop when calling setup from start. I prefer explicitly loading it again. This series is a collection of patches derived from [1] that pave the way for new targets, e.g. target-efi[2]. These patches mostly address the elimination of memory map assumptions and they shouldn't have any functional changes. The last two patches are a couple of patches not related to the memory map, but they also prepare for bare metal targets. I tossed them in since I don't think they should be too controversial. This patch series is also available here [3].
