This fixes the possible link/relo errors, since restore_regs will be provided by ISA code, but called from ARC common code. The .L prefix reassures binutils that it will be in same compilation unit. Signed-off-by: NVineet Gupta <vgupta@synopsys.com>

That is because __after_dc_op() already reads it for status check, so it is better anyways to use that "newer" value. Also reduces the clutter in callers for passing from/to these routines. Signed-off-by: NVineet Gupta <vgupta@synopsys.com>

As DW Mobile Storage databook says it's required to use "Hold Register" if card is enumerated in SDR12 or SDR25 modes. It means we need to act in the same way as in Altera's Socfpga implementation - set "use hold reg" bit in commad. Note that for upstream proper solution would be to remove dw_mci_pltfm_prepare_command() at all and set the bit right in dw_mci_prepare_command() for all platforms.

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.

Back when ARC700 4.10 was released, the related kernel features were tied to this config item so they could be disabled in one shot (i.e. LLOCK/SCOND, SWAPE, RTSC..) That having happened a while back, all new ARC customers weill get 4.11+ so those features can be assumed to be present and need not be tied to a top-level (we still retain the ability to individually disable them). Further, since ARCv2 also shares some of those feautes, removing it simplifies things a bit in Kconfig Signed-off-by: NVineet Gupta <vgupta@synopsys.com>
