[OpenWrt-Devel] [PATCH 2/2 v2] linux: add support of Synopsys ARCHS38-based boards
Alexey Brodkin

Mon Jan 18 12:51:58 EST 2016
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.

+ * According to DW Mobile Storage databook it is required
+ * to use "Hold Register" if card is enumerated in SDR12 or
+ * SDR25 modes.
+ *
+ * Utilization of "Hold Register" is already implemented via
+ * dw_mci_pltfm_prepare_command() which in its turn gets
+ * used through dw_mci_drv_data->prepare_command call-back.
+ * This call-back is used in Altera Socfpga platform and so
+ * we may reuse it saying that we're compatible with their
+ * "altr,socfpga-dw-mshc".
+ *
+ * Most probably "Hold Register" utilization is platform-
+ * independent requirement which means that single unified
+ * "snps,dw-mshc" should be enough for all users of DW MMC once
+ * dw_mci_pltfm_prepare_command() is used in generic platform
+ * code.
