About the RFI instruction on Linux Powerpc

[Wang Matthew-R59995]

Hi folks,
 
Currently I meet an issue about rfi instruction. Please see the
following source code. This source code is contained at the
head_fsl_booke.h of ./arch/powerpc/kernel directory.
 
 xori r6,r4,1
 slwi r6,r6,5  /* setup new context with other address space */
 bl 1f  /* Find our address */
1: mflr r9
 rlwimi r7,r9,0,20,31
 addi r7,r7,24
 mtspr SPRN_SRR0,r7
 mtspr SPRN_SRR1,r6
 rfi

I found that rfi instruction can't jump to the address of SRR0. I take
the MPC8555CDS board to do those test. And I don't take U-Boot as
bootloader, while the Vxwerks Bootrom.
 
I just want to try if Bootrom can bring up the Linux Powerpc kernel.
 
Any suggestion for that?
 
B.R
Wang Qi.
