I think we need update the existing sysreset_x86 driver to support SYSRESET_POWER_OFF, instead of creating a new driver to do such. We can add a new PCH ioctl code to get the pmbase, and do the ACPI power off in the sysreset_x86 driver. > Signed-off-by: Simon Glass <[email protected]> > --- > > arch/x86/cpu/broadwell/Kconfig | 1 + > drivers/sysreset/Kconfig | 9 ++ > drivers/sysreset/Makefile | 1 + > drivers/sysreset/sysreset_intel_pch.c | 125 ++++++++++++++++++++++++++ > 4 files changed, 136 insertions(+) > create mode 100644 drivers/sysreset/sysreset_intel_pch.c > Regards, Bin _______________________________________________ U-Boot mailing list [email protected] https://lists.denx.de/listinfo/u-boot
