+# - install : install headers, project library, and some programs
+# - clean : remove all generated content (except autoconf files)
+# - dist : make a source tarball
+# - distcheck : make a source tarball, untar it, check it, clean it
+# - distclean : remove everything

+RISC-V Proxy Kernel and Boot Loader
+=====================================
+
+About
+---------
+
+The RISC-V Proxy Kernel, `pk`, is a lightweight application execution
+environment that can host statically-linked RISC-V ELF binaries. It is
+designed to support tethered RISC-V implementations with limited I/O
+capability and and thus handles I/O-related system calls by proxying them to
+a host computer.
+
+This package also contains the Berkeley Boot Loader, `bbl`, which is a
+supervisor execution environment for tethered RISC-V systems. It is
+designed to host the RISC-V Linux port.
+
+Build Steps
+---------------
+
+We assume that the RISCV environment variable is set to the RISC-V tools
+install path, and that the riscv-gnu-toolchain package is installed.
+Please note that building the binaries directly inside the source
+directory is not supported; you need to use a separate build directory.
+
+ $ mkdir build
+ $ cd build
+ $ ../configure --prefix=$RISCV --host=riscv64-unknown-elf
+ $ make
+ $ make install
+
+Alternatively, the GNU/Linux toolchain may be used to build this package,
+by setting `--host=riscv64-unknown-linux-gnu`.
+
+By default, 64-bit (RV64) versions of `pk` and `bbl` are built. To
+built 32-bit (RV32) versions, supply a `--enable-32bit` flag to the
+configure command.
+
+The `install` step installs 64-bit build products into a directory
+matching your host (e.g. `$RISCV/riscv64-unknown-elf`). 32-bit versions
+are installed into a directory matching a 32-bit version of your host (e.g.
+`$RISCV/riscv32-unknown-elf`).

+# Local Autoconf Macros
+#=========================================================================
+# This file contains the macros for the Modular C++ Build System and
+# additional autoconf macros which developers can use in their
+# configure.ac scripts. Please read the documentation in
+# 'mcppbs-doc.txt' for more details on how the Modular C++ Build System
+# works. The documenation for each macro should include information
+# about the author, date, and copyright.
+
+#-------------------------------------------------------------------------
+# MCPPBS_PROG_INSTALL
+#-------------------------------------------------------------------------
+# This macro will add an --enable-stow command line option to the
+# configure script. When enabled, this macro will first check to see if
+# the stow program is available and if so it will set the $stow shell
+# variable to the binary name and the $enable_stow shell variable to
+# "yes". These variables can be used in a makefile to conditionally use
+# stow for installation.
+#
+# This macro uses two environment variables to help setup default stow
+# locations. The $STOW_PREFIX is used for stowing native built packages.
+# The packages are staged in $STOW_PREFIX/pkgs and then symlinks are
+# created from within $STOW_PREFIX into the pkgs subdirectory. If you
+# only do native builds then this is all you need to set. If you don't
+# set $STOW_PREFIX then the default is just the normal default prefix
+# which is almost always /usr/local.
+#
+# For non-native builds we probably want to install the packages in a
+# different location which includes the host architecture name as part
+# of the prefix. For these kind of builds, we can specify the $STOW_ROOT
+# environment variable and the effective prefix will be
+# $STOW_ROOT/${host_alias} where ${host_alias} is specified on the
+# configure command line with "--host".
+#
+# Here is an example setup:
+#

+#
+# Subproject names can also include a ** suffix which indicates that it
+# is an optional subproject, but there is a group with the same name.
+# Thus the --enable-<sproj> command line option will enable not just the

+# There is no error checking to make sure that if you use the ** suffix

+\`configure' configures RISC-V Proxy Kernel ? to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]

+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CXX C++ compiler command
+ CXXFLAGS C++ compiler flags
+ STOW_ROOT Root for non-native stow-based installs
+ STOW_PREFIX Prefix for stow-based installs
+ CPP C preprocessor
+ RISCV top-level RISC-V install directory
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+# This script will create a version string by querying a version control
+# system. The string is appropriate for use in installations and
+# distributions. Currently this script assumes we are using git as our
+# version control system but it would be possible to check and see if we
+# are using an alternative version control system and create a version
+# string appropriately.
+#
+# The script uses git describe plus a few other git commands to create a
+# version strings in the following format:
+#
+# X.Y[-Z-gN][-dirty]
+#
+# where X is the major release, Y is the minor release, Z is the number
+# of commits since the X.Y release, N is an eight digit abbreviated SHA
+# hash of the most recent commit and the dirty suffix is appended when
+# the working directory used to create the installation or distribution
+# is not a pristine checkout. Here are some example version strings:
+#
+# 0.0 : initial import
+# 0.0-3-g99ef6933 : 3rd commit since initial import (N=99ef6933)
+# 1.0 : release 1.0
+# 1.1-12-g3487ab12 : 12th commit since release 1.1 (N=3487ab12)
+# 1.1-12-g3487ab12-dirty : 12th commit since release 1.1 (N=3487ab12)
+#
+# The last example is from a dirty working directory. To find the last
+# release, the script looks for the last tag (does not need to be an
+# annotated tag, but probably should be) which matches the format rel-*.
+# If there is no such tag in the history, then the script uses 0.0 as
+# the release number and counts the total number of commits since the
+# original import for the commit count.
+#
+# If the current directory is not within the working directory, then the
+# path to the source directory should be supplied on the command line.

+Subject: [PATCH 09/11] RISC-V: Networking fix Hack
+
+It looks like that kernel driver now supports reseting the
+signal one additional time. As it had been already reset
+twice in FSBL, PHY gets into incorrect state causing below error.
+
+----------------------------------------------------------------------
+macb 10090000.ethernet (unnamed net_device) (uninitialized): Could not attach to PHY
+macb: probe of 10090000.ethernet failed with error -110
+----------------------------------------------------------------------
+
+This patch is just a temporary fix until we have a fix a FSBL.
+It is just a **HACK** and **NOT TO BE MERGED** into mainline.

++SiFive U54 SoC clocks
++
++This binding uses the common clock binding:
++ Documentation/devicetree/bindings/clock/clock-bindings.txt
++
++The U54 PRCI controller generates clocks for the U54 SoC. There is
++a core PLL that sets the processor frequency and PLLs for ethernet
++and DDR. It takes an input clock from the board, typically an oscillator
++or crystal.
++
++Required properties:
++- compatible: Should be "sifive,aloeprci0"
++- #clock-cells: Should be <1>
++- reg: Specifies base physical address and size of the registers
++- clocks: phandles to the parent clock used as input
++
++Example:
++
++ refclk: refclk {
++ #clock-cells = <0>;
++ compatible = "fixed-clock";
++ clock-frequency = <33333333>;
++ clock-output-names = "xtal";

++TX clock switch for GEMGXL in U540 SoCs
++
++This binding uses the common clock binding:

++The U54 includes a clock mux to control the ethernet TX frequenecy. It
++switches between the local TX clock (125MHz) and PHY TX clocks. This is
++necessary to toggle between 1Gb and 100/10Mb speeds.
++
++Required properties:

++SiFive GPIO controller bindings
++
++Required properties:
++- compatible:
++ - "sifive,gpio0"
++- reg: Physical base address and length of the controller's registers.
++- #gpio-cells : Should be 2
++ - The first cell is the gpio offset number.
++ - The second cell indicates the polarity of the GPIO
++- gpio-controller : Marks the device node as a GPIO controller.
++- interrupt-controller: Mark the device node as an interrupt controller
++- #interrupt-cells : Should be 2.
++ - The first cell is the GPIO offset number within the GPIO controller.
++ - The second cell is the edge/level to use for interrupt generation.
++- interrupts: Specify the interrupts, one per GPIO
++
++Example:
++
++gpio: gpio@10060000 {
++ compatible = "sifive,gpio0";
++ interrupt-parent = <&plic>;
++ interrupts = <7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22>;
++ reg = <0x0 0x10060000 0x0 0x1000>;
++ gpio-controller;
++ #gpio-cells = <2>;
++ interrupt-controller;
++ #interrupt-cells = <2>;
++};
