It has to be copied to RAM anyway so\nstoring it uncompressed is arguably a waste of ROM resources.\n\nWhile at it, the copying of .data (when not compressed) and the\nclearing of .bss is now performed using optimized string routines\nrather than doing it one word at a time.\n\nThis work highlighted some defficiencies in linker scripts, especially\nthe XIP one. So this also includes linker script cleanups and fixes.\n\nThis series is also available here:\n\nhttp://git.linaro.org/people/nicolas.pitre/linux xip_zdata\n\nChanges from v1:\n\n- Added major fixes to vmlinux-xip.lds.S\n- Added extra cleanups to vmlinux.lds.S\n- improvements to deflate_xip_data.sh for easier debugging\n- __bss_stop aligned to 64 bits for stack usage in the XIP case\n- Various commit message clarifications\n \ndiffstat:\n\n arch/arm/Kconfig                    | 11 ++++\n arch/arm/boot/Makefile              | 13 ++++-\n arch/arm/boot/deflate_xip_data.sh   | 64 +++++++++++++++++++++\n arch/arm/kernel/Makefile            |  5 ++\n arch/arm/kernel/head-common.S       | 85 +++++++++++++++++-----------\n arch/arm/kernel/head-inflate-data.c | 62 ++++++++++++++++++++\n arch/arm/kernel/vmlinux-xip.lds.S   | 94 ++++++++++++++-----------------\n arch/arm/kernel/vmlinux.lds.S       | 40 ++-----------\n 8 files changed, 256 insertions(+), 118 deletions(-)"}
