There was a bunch of dead historical cruft floating around in the arch/xtensa tree, left over from older code versions. It's time to do a cleanup pass. This is entirely refactoring and size optimization, no behavior changes on any in-tree devices should be present. Among the more notable changes: + xtensa_context.h offered an elaborate API to deal with a stack frame and context layout that we no longer use. + xtensa_rtos.h was entirely dead code + xtensa_timer.h was a parallel abstraction layer implementing in the architecture layer what we're already doing in our timer driver. + The architecture thread structs (_callee_saved and _thread_arch) aren't used by current code, and had dead fields that were removed. Unfortunately for standards compliance and C++ compatibility it's not possible to leave an empty struct here, so they have a single byte field. + xtensa_api.h was really just some interrupt management inlines used by irq.h, so fold that code into the outer header. + Remove the stale assembly offsets. This architecture doesn't use that facility. All told, more than a thousand lines have been removed. Not bad. Signed-off-by: Andy Ross <andrew.j.ross@intel.com> |
