This patch series implements vmlinux.bin and vmlinuz.bin appended dtb support, and adds a user for the vmlinux one. The first two patches add the appropriate support for vmlinux.bin and vmlinuz.bin. Since enabling it for both does not make sense (and is potentially dangerous) I made it a choice for which variant it should be enabled. Patches three and four then add BMIPS as a test user for this implementation. vmlinuz.bin was tested by selecting SYS_SUPPORTS_ZBOOT and setting zload-y to 0x81000000 (ramstart + 16 MiB, so the kernel is loaded behind CFE), then wrapping vmlinuz_w_dtb.bin in the CFE expected lzma with appropriate header to unpack there. For easier testing/using I changed boot/dts/brcm to build all dts files as dtb blobs in case no built in dtb is selected. Completely untested on anything except MIPS32 / big endian. Obviously it won't work with an ELF kernel. I did not have a reasonable idea how to do that except by parsing the elf header from head.S, and that seemed a bit insane. Regards Jonas Changes RFC v2 -> v3 * Switched to UHI specs interface instead of manipulating initial_boot_params * fixed boot on !SMP * Changed PTR_LW to lw and PTR_LI to li to ensure 32bit loads/ comparisons are done also on 64 bit * Added vmlinuz.bin support * Added bmips as a user Changes RFC v1 -> v2 * changed all occurences of vmlinux to vmlinux.bin * clarified this applies to the raw vmlinux.bin without decompressor * s/initial_device_params/initial_boot_params/ Jonas Gorski (4): MIPS: add support for vmlinux.bin appended dtb MIPS: add support for vmlinuz.bin appended dtb MIPS: BMIPS: build all dtbs if no builtin dtb MIPS: BMIPS: accept UHI interface for passing a dtb arch/mips/Kconfig | 45 +++++++++++++++++++++++++++++++++++ arch/mips/bmips/setup.c | 2 ++ arch/mips/boot/compressed/head.S | 16 +++++++++++++ arch/mips/boot/compressed/ld.script | 6 ++++- arch/mips/boot/dts/brcm/Makefile | 13 ++++++++++ arch/mips/kernel/head.S | 16 +++++++++++++ arch/mips/kernel/vmlinux.lds.S | 8 ++++++- 7 files changed, 104 insertions(+), 2 deletions(-) -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
