From 4f17664a4407004f71dc76de01c89fdb6efc0776 Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Fri, 31 Jan 2020 21:25:03 -0800 Subject: xtensa: separate SMP and XIP support There's no real dependency between SMP and XIP, allow them to be selected together. Always define 2- and 4-argument SECTION_VECTOR macros, always use 4-argument macro for the secondary reset vector and always define relocation entry for it.
