2014-04-02xtensa: split bootparam and kernel meminfoMax Filippov
Bootparam meminfo is a bootloader ABI, kernel meminfo is for the kernel bookkeeping, keep them separate. Kernel doesn't care of memory region types, so drop the type field and don't pass it to add_sysmem_bank. Move kernel sysmem structures and prototypes to asm/sysmem.h and sysmem variable and add_sysmem_bank to mm/init.c Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

2012-12-18xtensa: add device trees supportMax Filippov
Device trees allow specification of hardware topology and device parameters at runtime instead of hard-coding them in platform setup code. This allows running single binary kernel on a range of compatible boards. New boot parameters tag BP_TAG_FDT is allocated and a pointer to flat device tree is passed in it. Note that current interrupt mapping scheme uses single cell for interrupt identification. That means that IRQ numbers used in DTS must be CPU internal IRQ numbers, not external. It is possible to extend interrupt identification to two cells, and use second cell to tell external IRQ numbers form internal. That would allow to use single DTS on multiple boards with different mapping of external IRQ numbers. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Chris Zankel <chris@zankel.net>
2008-11-06xtensa: move headers files to arch/xtensa/includeChris Zankel
Move all header files for xtensa to arch/xtensa/include and platform and variant header files to the appropriate arch/xtensa/platforms/ and arch/xtensa/variants/ directories. Moving the files gets also rid of all uses of symlinks in the Makefile. This has been completed already for the majority of the architectures and xtensa is one out of six missing.
