ARC: [plat-hsdk] initial port for HSDK board This initial port adds support of ARC HS Development Kit board with some basic features such serial port, USB, SD/MMC and Ethernet. Essentially we run Linux kernel on all 4 cores (i.e. utilize SMP) and heavily use IO Coherency for speeding-up DMA-aware peripherals. Note as opposed to other ARC boards we link Linux kernel to 0x9000_0000 intentionally because cores 1 and 3 configured with DCCM situated at our more usual link base 0x8000_0000. We still can use memory region starting at 0x8000_0000 as we reallocate DCCM in our platform code. Note that PAE remapping for DMA clients does not work due to an RTL bug, so CREG_PAE register must be programmed to all zeroes, otherwise it will cause problems with DMA to/from peripherals even if PAE40 is not used.

ARCv2: [plat-hsdk]: Save accl reg pair by default This manifsted as strace segfaulting on HSDK because gcc was targetting the accumulator registers as GPRs, which kernek was not saving/restoring by default. Cc: stable@vger.kernel.org #4.14+ Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

ARCv2: support manual regfile save on interrupts There's a hardware bug which affects the HSDK platform, triggered by micro-ops for auto-saving regfile on taken interrupt. The workaround is to inhibit autosave. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

arc: plat-hsdk: fix kconfig dependency warning when !RESET_CONTROLLER When ARC_SOC_HSDK is enabled and RESET_CONTROLLER is disabled, it results in the following Kbuild warning: WARNING: unmet direct dependencies detected for RESET_HSDK Depends on [n]: RESET_CONTROLLER [=n] && HAS_IOMEM [=y] && (ARC_SOC_HSDK [=y] || COMPILE_TEST [=n]) Selected by [y]: - ARC_SOC_HSDK [=y] && ISA_ARCV2 [=y] The reason is that ARC_SOC_HSDK selects RESET_HSDK without depending on or selecting RESET_CONTROLLER while RESET_HSDK is subordinate to RESET_CONTROLLER. Honor the kconfig menu hierarchy to remove kconfig dependency warnings.

PCI: consolidate PCI config entry in drivers/pci There is no good reason to duplicate the PCI menu in every architecture. Instead provide a selectable HAVE_PCI symbol that indicates availability of PCI support, and a FORCE_PCI symbol to for PCI on and the handle the rest in drivers/pci.
