ARM: sti: Add STiH415 SOC support The STiH415 is the next generation of HD, AVC set-top box processors for satellite, cable, terrestrial and IP-STB markets. It is an ARM Cortex-A9 1.0 GHz, dual-core CPU.

ARM: sti: remove custom .init_time hook With arch/arm calling of_clk_init(NULL) from time_init(), we can now remove custom .init_time hooks. To get rid of it, move l2cc init to .init_machine hook instead. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> Acked-by: Srinivas Kandagatla <srinivas.kandagatla@st.com>

ARM: appropriate __init annotation for const data Init data marked const should be annotated with __initconst for correctness and not __initdata. In some cases the array gathering references to that data has to be marked const as well. This fixes LTO builds that otherwise fail with section mismatch errors.

ARM: STi: Update machine _namestr to be more generic. This string is used by dump_stack and as we now support more SoC's than just STiH415/6 it is misleading to have the current string in the stack trace. This patch updates it to be more generic for the STi family of SoCs.
