Patch to ARM's redboot_linux_exec.c file

Hello All,
I ran into an issue with the Redboot "exec" command on an ARM-based platform. After copying the downloaded kernel to the entry address, the PC was getting set to an incorrect entry address thereby causing the kernel decompression step to fail.
 
On further debugging, I found that Register r2 was being used to store the "entry" input operand in the inline assembly code at the end of the do_exec() function. 

r2 is also used to store the Linux kernel parameters, I have attached a patch to fix this issue.
 
Best Regards,
-Mahesh
