Hello Marek,
As done in PPC for all the Socs for FSL, in arch/powerpc/cpu/mpc83xx/start.S ,
and ARM v7 LS1021, in arch/arm/cpu/armv7/ls102xa/cpu.c, this uint get_svr(void)
function finds the svr number for the SoC. Now, as i have to make the code
generic for PPC and ARM (in patch 3/5 namely make errata function common for
PPC and ARM), I am currently having the same name and return type used.
Regards,
Sriram
