This SoC runs 2 OpenRISC CPUs at 50Mhz with 32MB ram, UART for console and GPIOs for LEDs. This FPGA SoC is based on the simple-smp reference board and brings in devices from the de0 nano common DTSI file. A default config is added that brings together the device tree and driver setup.

We also take this opportunity to swich underscores to dashes as that seems to be the more common convention for DTS files. Signed-off-by: Stafford Horne <shorne@gmail.com>

Add a base configuration for the board that runs an OpenRISC CPU at 50Mhz with 32MB ram, UART for console and some GPIOs for LEDs and switches. There is an older version of this floating around that defines all of the hardware on the board including SPI's, flash devices, sram, ADCs etc. Eventually it would be good to get the full version upstream but for now I think a minimal board is good to start with.

kbuild: do not quote string values in include/config/auto.conf 2022-01-08T09:03:57+00:00 Masahiro Yamada masahiroy@kernel.org 2021-12-14T02:53:53+00:00 129ab0d2d9f38b9d43df35235fc66c6740d6928b The previous commit fixed up all shell scripts to not include include/config/auto.conf.

We must rip them off when used. There are some patterns: [1] $(patsubst "%",%,$(CONFIG_X)) [2] $(CONFIG_X:"%"=%) [3] $(subst ",,$(CONFIG_X)) [4] $(shell echo $(CONFIG_X)) These are not only ugly, but also fragile. [1] and [2] do not work if the value contains spaces, like CONFIG_X=" foo bar " [3] does not work correctly if the value contains double-quotes like CONFIG_X="foo\"bar" [4] seems to work better, but has a cost of forking a process.

The previous commit fixed up all shell scripts to not include
include/config/auto.conf.

Now that include/config/auto.conf is only included by Makefiles,
we can change it into a more Make-friendly form.

Previously, Kconfig output string values enclosed with double-quotes
(both in the .config and include/config/auto.conf):

    CONFIG_X="foo bar"

Unlike shell, Make handles double-quotes (and single-quotes as well)
verbatim. We must rip them off when used.

There are some patterns:

  [1] $(patsubst "%",%,$(CONFIG_X))
  [2] $(CONFIG_X:"%"=%)
  [3] $(subst ",,$(CONFIG_X))
  [4] $(shell echo $(CONFIG_X))

These are not only ugly, but also fragile.

[1] and [2] do not work if the value contains spaces, like
   CONFIG_X=" foo bar "

[3] does not work correctly if the value contains double-quotes like
   CONFIG_X="foo\"bar"

[4] seems to work better, but has a cost of forking a process.

Anyway, quoted strings were always PITA for our Makefiles.

Fisrt off, the compatible property used an obsolete compatibility string; this caused the initialization to be skipped. Next, the register map was not given enough space to allocate ring descriptors, this caused module initialization to abort. Finally, we need to mark this device as big-endian as needed by openrisc.
