powerpc/boot: Explicitly disable usage of SPE instructions

2022-10-26T11:25:11Z

commit 110a58b9f91c66f743c01a2c217243d94c899c23 upstream. uImage boot wrapper should not use SPE instructions, like kernel itself. Boot wrapper has already disabled Altivec and VSX instructions but not SPE. Options -mno-spe and -mspe=no already set when compilation of kernel, but not when compiling uImage wrapper yet. Fix it.

powerpc/boot: Fix build of dts/fsl

2020-12-30T10:54:01Z

[ Upstream commit b36f835b636908e4122f2e17310b1dbc380a3b19 ] The lkp robot reported that some configs fail to build, for example mpc85xx_smp_defconfig, with: cc1: fatal error: opening output file arch/powerpc/boot/dts/fsl/.mpc8540ads.dtb.dts.tmp: No such file or directory This bisects to: cc8a51ca6f05 ("kbuild: always create directories of targets") Although that commit claims to be about in-tree builds, it somehow breaks out-of-tree builds. But presumably it's just exposing a latent bug in our Makefiles. We can fix it by adding to targets for dts/fsl in the same way that we do for dts.

powerpc/boot: Update Makefile comment for 64bit wrapper

2020-09-08T12:24:19Z

As of commit 147c05168fc8 ("powerpc/boot: Add support for 64bit little endian wrapper") the comment in the Makefile is misleading. The wrapper packaging 64bit kernel may built as a 32 or 64 bit elf. Update the comment to reflect this. Signed-off-by: Jordan Niethe Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/20200825035147.3239-1-jniethe5@gmail.com

powerpc/boot: Fix CONFIG_PPC_MPC52XX references

2020-07-29T11:08:22Z

Commit 866bfc75f40e ("powerpc: conditionally compile platform-specific serial drivers") made some code depend on CONFIG_PPC_MPC52XX, which doesn't exist. Fix it to use CONFIG_PPC_MPC52xx.

powerpc/boot: add DTB to 'targets'

2020-07-22T00:19:12Z

PowerPC always re-builds DTB even if nothing has been changed. As for other architectures, arch/*/boot/dts/Makefile builds DTB by using the dtb-y syntax. In contrast, arch/powerpc/boot/dts/(fsl/)Makefile does nothing unless CONFIG_OF_ALL_DTBS is defined. Instead, arch/powerpc/boot/Makefile builds DTB on demand. You need to add DTB to 'targets' explicitly so .*.cmd files are included. Signed-off-by: Masahiro Yamada Acked-by: Michael Ellerman

powerpc: Remove Xilinx PPC405/PPC440 support

2020-05-28T13:24:34Z

The latest Xilinx design tools called ISE and EDK has been released in October 2013. New tool doesn't support any PPC405/PPC440 new designs. These platforms are no longer supported and tested. PowerPC 405/440 port is orphan from 2013 by commit cdeb89943bfc ("MAINTAINERS: Fix incorrect status tag") and commit 19624236cce1 ("MAINTAINERS: Update Grant's email address and maintainership") that's why it is time to remove the support fot these platforms.
