MIPS: dts: Boston: Fix PCI bus dtc warnings:

2018-06-20T19:01:15+00:00

[ Upstream commit 2c2bf522ed8cbfaac666f7dc65cfd38de2b89f0f ] dtc recently (v1.4.4-8-g756ffc4f52f6) added PCI bus checks. Fix the warnings now emitted: arch/mips/boot/dts/img/boston.dtb: Warning (pci_bridge): /pci@10000000: missing bus-range for PCI bridge arch/mips/boot/dts/img/boston.dtb: Warning (pci_bridge): /pci@12000000: missing bus-range for PCI bridge arch/mips/boot/dts/img/boston.dtb: Warning (pci_bridge): /pci@14000000: missing bus-range for PCI bridge Signed-off-by: Matt Redfearn Cc: Ralf Baechle Cc: Paul Burton Cc: Rob Herring Cc: Mark Rutland Cc: linux-mips@linux-mips.org Cc: devicetree@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/19070/ Signed-off-by: James Hogan Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

MIPS: Fix build with DEBUG_ZBOOT and MACH_JZ4770

2018-05-30T06:17:14+00:00

commit c60128ce97674fd05adb8b5ae79eb6745a03192e upstream. The debug definitions were missing for MACH_JZ4770, resulting in a build failure when DEBUG_ZBOOT was set. Since the UART addresses are the same across all Ingenic SoCs, we just use a #ifdef CONFIG_MACH_INGENIC instead of checking for individual Ingenic SoCs. Additionally, I added a #define for the UART0 address in-code and dropped the include, for the reason that this include file is slowly being phased out as the whole platform is being moved to devicetree.

MIPS: xilfpga: Stop generating useless dtb.o

commit a5a92abbce56c41ff121db41a33b9c0a0ff39365 upstream. A dtb.o is generated from nexys4ddr.dts but this is never used since it has been moved to mips/generic with commit b35565bb16a5 ("MIPS: generic: Add support for MIPSfpga").

zboot: fix stack protector in compressed boot phase

2018-04-19T06:54:08+00:00

commit 7bbaf27d9c83037b6e60a818e57bdbedf6bc15be upstream. Calling __stack_chk_guard_setup() in decompress_kernel() is too late that stack checking always fails for decompress_kernel() itself. So remove __stack_chk_guard_setup() and initialize __stack_chk_guard before we call decompress_kernel(). Original code comes from ARM but also used for MIPS and SH, so fix them together. If without this fix, compressed booting of these archs will fail because stack checking is enabled by default (>=4.16).

MIPS: boot: Define ASSEMBLY for its.S build

2018-02-23T01:06:25+00:00

The MIPS %.its.S compiler command did not define __ASSEMBLY__, which meant when compiler_types.h was added to kconfig.h, unexpected things appeared (e.g. struct declarations) which should not have been present. As done in the general %.S compiler command, __ASSEMBLY__ is now included here too. The failure was: Error: arch/mips/boot/vmlinux.gz.its:201.1-2 syntax error FATAL ERROR: Unable to parse input tree /usr/bin/mkimage: Can't read arch/mips/boot/vmlinux.gz.itb.tmp: Invalid argument /usr/bin/mkimage Can't add hashes to FIT blob Reported-by: kbuild test robot Fixes: 28128c61e08e ("kconfig.h: Include compiler types to avoid missed struct attributes") Signed-off-by: Kees Cook Signed-off-by: Linus Torvalds

MIPS: Fix clean of vmlinuz.{32,ecoff,bin,srec}

2018-01-18T21:53:14+00:00
