2011-09-28arm/imx: change mxc_init_l2x0() to an imx31/35 specific callShawn Guo3-57/+38
The mxc_init_l2x0() should really be an imx31/35 specific call. The patch removes early_initcall from mxc_init_l2x0() and get imx31 and imx35 soc specific function calls mxc_init_l2x0(), so that it's not necessarily to be called for all imx socs when we build single image for multiple imx socs. Thus the function can be renamed to imx3_init_l2x0() and put into mm-imx3.c. It also changes the return type from integer to void. From what I see, the integer was picked just to satisfy early_initcall prototype. With the patch 'ARM: l2x0: add empty l2x0_of_init' applied, the code compiles even without CONFIG_CACHE_L2X0 enabled.
