ARC: [plat-hsdk] initial port for HSDK board

2017-09-01T18:26:28+00:00

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: [axs101] support early 8250 uart

2015-06-19T12:39:30+00:00

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.
