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.

ARC: [plat-hsdk] use actual clk driver to manage cpu clk With corresponding clk driver now merged upstream, switch to it. - core_clk now represent the PLL (vs. fixed clk before) - input_clk represent the clk signal src for PLL (basically xtal) Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com> 2017-09-04 09:48:43 +00:00			`bool "ARC HS Development Kit SOC"`
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.

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> 2018-06-06 17:20:37 +00:00			`select ARC_IRQ_NO_AUTOSAVE`

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.
