Re: [Qemu-arm] [PATCH] target-arm/helper.c: fix access rights of SP_ELs

The ARM ARM defines that SP_EL1 is accessible only from
EL2 or higher via the system-register instructions, and
SP_EL2 only from EL3 or higher (see table C5-7 on page
C5-288 of the v8 ARM ARM DDI0487A.h, or the register description
pages for the two registers). Why do you think this is a correct
change?

Thanks for the correction. Seems like I misunderstood the spec.

 

thanks
