ARC: [axs101] Add support for AXS101 SDP (software development platform) The AXS10x platforms consist of a mainboard with peripherals, on which several daughter cards can be placed. The daughter cards typically contain a CPU and memory.

arc: Add "model" properly in device tree description of all boards As it was discussed quite some time ago (see https://lkml.org/lkml/2015/11/5/862) it's a good practice to add "model" property in .dts. Moreover as per ePAPR "model" property is required and should look like "manufacturer,model" so we do here.

ARC: [axs101] support early 8250 uart Earlycon calculates UART clock as "BASE_BAUD * 16". In case of ARC "BASE_BAUD" is calculated dynamically in runtime, basically it is an alias to arc_early_base_baud(), which in turn just does "arc_base_baud/16". 8250 UART on AXS/SDP board uses 33.3MHz clock source which is set in "arc_base_baud" with this change. Additional compatibility string "snps,arc-sdp" is introduced as well because there're different flavours of AXS boards but they all share the same motherboard and so it's possible to re-use the same code for motherbord even if CPU daughterboard changes.

ARC: Enable fatal signals on boot for dev platforms It's very convenient to have fatal signals enabled on developemnt platform as this allows to catch problems that happen early in user-space (like crashing init or dynamic loader). Otherwise we may either enable it later from alive taregt console by "echo 1 > /proc/sys/kernel/print-fatal-signals" but: 1. We might be unfortunate enough to not reach working console 2. Forget to enable fatal signals and miss something interesting Given we're talking about development platforms here it shouldn't be a problem if a bit more data gets printed to debug console. Moreover this makes behavior of all our dev platforms predictable as today some platforms already have it enabled and some don't - which is way too inconvenient.
