2017-03-27ARM: omap2+: Revert omap-smp.c changes resetting CPU1 during bootTony Lindgren1-1/+1
Commit 3251885285e1 ("ARM: OMAP4+: Reset CPU1 properly for kexec") started unconditionally resetting CPU1 because of a kexec boot issue I was seeing earlier on omap4 when doing kexec boot between two different kernel versions. This caused issues on some systems. We should only reset CPU1 as a last resort option, and try to avoid it where possible. Doing an unconditional CPU1 reset causes issues for example when booting a bootloader configured secure OS running on CPU1 as reported by Andrew F. Davis <[email protected]>. We can't completely remove the reset of CPU1 as it would break kexec booting from older kernels. But we can limit the CPU1 reset to cases where CPU1 is wrongly parked within the memory area used by the booting kernel. Then later on we can add support for parking CPU1 for kexec out of the SDRAM back to bootrom. So let's first fix the regression reported by Andrew by making CPU1 reset conditional. To do this, we need to: 1. Save configured AUX_CORE_BOOT_1 for later 2. Modify AUX_CORE_BOOT_0 reading code to for HS SoCs to return the whole register instead of the CPU mask 3. Check if CPU1 is wrongly parked into the booting kernel by the previous kernel and reset if needed Fixes: 3251885285e1 ("ARM: OMAP4+: Reset CPU1 properly for kexec") Reported-by: Andrew F.

2015-10-22ARM: Remove __ref on hotplug cpu die pathStephen Boyd1-1/+1
Now that __cpuinit has been removed, the __ref markings on these functions are useless. Remove them. This also reduces the size of the multi_v7_defconfig image: $ size before after text data bss dec hex filename 12683578 1470996 348904 14503478 dd4e36 before 12683274 1470996 348904 14503174 dd4d06 after presumably because now we don't have to jump to code in the .ref.text section and/or the noinline marking is removed.

2014-05-08ARM: OMAP2+: raw read and write endian fixVictor Kamensky1-2/+2
All OMAP IP blocks expect LE data, but CPU may operate in BE mode. Need to use endian neutral functions to read/write h/w registers. I.e instead of __raw_read[lw] and __raw_write[lw] functions code need to use read[lw]_relaxed and write[lw]_relaxed functions. If the first simply reads/writes register, the second will byteswap it if host operates in BE mode. Changes are trivial sed like replacement of __raw_xxx functions with xxx_relaxed variant.

2013-03-28ARM: OMAP4+: Remove the un-necessary cache flush from hotplug codeSantosh Shilimkar1-6/+0
This was added with intial port where OMAP PM support wasn't existing and only simple WFI based hooks were used. This should have been cleaned up while adding the PM support but some how fall through cracks. So remove the cache flush code which is no longer needed now.

WARNING: vmlinux.o(.text+0x226d0): Section mismatch in reference from the function platform_cpu_die() to the function .cpuinit.text:omap4_hotplug_cpu() The function platform_cpu_die() references the function __cpuinit omap4_hotplug_cpu(). This is often because platform_cpu_die lacks a __cpuinit annotation or the annotation of omap4_hotplug_cpu is wrong.
