More testing done with above configuration + kexec_tools change below: initrd_base = kernel_base + _ALIGN(len * 7, getpagesize()); kexec works fine on: am437x-gp-evm, am437x-sk-evm am335x-bone dra72-evm dra7-evm omap5-uevm Tested-by: Keerthy Regards, Keerthy > > Regards, > > Tony > > > Tony Lindgren (4): > ARM: OMAP4+: Initialize SAR RAM base early for proper CPU1 reset for > kexec > ARM: OMAP4+: Prevent CPU1 related hang with kexec > ARM: OMAP4+: Reset CPU1 properly for kexec > ARM: OMAP4+: Allow kexec on SMP variants > > arch/arm/mach-omap2/Makefile | 4 +- > arch/arm/mach-omap2/common.h | 8 ++- > arch/arm/mach-omap2/io.c | 3 + > arch/arm/mach-omap2/omap-hotplug.c | 6 ++ > arch/arm/mach-omap2/omap-mpuss-lowpower.c | 29 ++++++++-- > arch/arm/mach-omap2/omap-smp.c | 96 ++++++++++++++++++++++--------- > arch/arm/mach-omap2/omap4-common.c | 14 ++--- > 7 files changed, 118 insertions(+), 42 deletions(-) >
