kbuild: restore arch/{ppc/xtensa}/boot cflags Commit 9a39e273d4df0560c724c5fe71f6314a0583ca2b removed the boot directory addition to CFLAGS that was being used by the subdirectory builds. For the other files, that patch set EXTRA_CFLAGS, but Makefile.build explicitly sets that to empty as it is explicitly for a single directory only. Append to KBUILD_CFLAGS instead.

xtensa: don't use echo -e needlessly -e is not needed to output strings without escape sequences. This breaks big endian FSF build when the shell is dash, because its builtin echo doesn't understand '-e' switch and outputs it in the echoed string.

xtensa: clean up bootable image build targets Currently xtensa uses 'zImage' as a synonym of 'all', but in fact xtensa supports three targets: 'Image' (ELF image with reset vector), 'zImage' (compressed redboot image) and 'uImage' (U-Boot image). Provide separate 'Image', 'zImage' and 'uImage' make targets that only build corresponding image type. Make 'all' build all images appropriate for a platform.

xtensa: add XIP kernel support XIP (eXecute In Place) kernel image is the image that can be run directly from ROM, using RAM only for writable data. XIP xtensa kernel differs from regular xtensa kernel in the following ways: - it has exception/IRQ vectors merged into text section. No vectors relocation takes place at kernel startup. - .data/.bss location must be specified in the kernel configuration, its content is copied there in the _startup function. - .init.text is merged with the rest of text and is executed from ROM. - when MMU is used the virtual address where the kernel will be mapped must be specified in the kernel configuration. It may be in the KSEG or in the KIO, __pa macro is adjusted to be able to handle both. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

xtensa: add NOTES section to the linker script This section collects all source .note.* sections together in the vmlinux image. Without it .note.Linux section may be placed at address 0, while the rest of the kernel is at its normal address, resulting in a huge vmlinux.bin image that may not be linked into the xtensa Image.elf.
