linux: add support of Synopsys ARCHS38-based boards This patch introduces support of new boards with ARC HS38 cores. ARC HS38 is a new generation of ARC cores which utilize ARCv2 ISA. As with ARC770 we're addind support for 2 boards for now: [1] Synopsys SDP board (AXS103) This is the same base-board as in AXS101 but with FPGA-based CPU-tile where ARCHs38 core is implemented. [2] nSIM Again this is the same simulation engine but configured for new instruction set and features of new CPU.

arc: Build uImage as well as vmlinux output files Initially for ARC we were building vmlinux images because it was both simpler and more convenient to debug Linux kernel in runt-time via JTAG. Now when base system works quite nice we may finally use U-Boot for loading the system image as well. Still we keep building vmlinux images as some of our boards are development boards and loading images with JTAG could be at some points very beneficial. Note for U-Boot header it's required to specify 2 values: * loading address * entry point (if it doesn't match loading address) and in case of ARC entry point (EP) not only differs from loading address but also changes from build to build due to initramfs being placed between loading address and text section. To accommodate that feature we have to calculate EP after vmlinux gets built and before call to mkimage. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

# On ARC initramfs is put before entry point and so entry point moves
# in memory from build to built. Thus we need to extract EP from vmlinux
# every time before generation of uImage.

image.mk: clean up redundant code related to DEVICE_DTS It is used by a core build template, so the variable should be initialized and added to DEVICE_VARS in the core. Same for DEVICE_DTS_DIR Signed-off-by: Felix Fietkau <nbd@nbd.name>
