Log:
Example scripts for the "manual" u-boot build process (i.e., without using
OpenEmbedded or anything similar.)

NOTE: this is still unfinished and largely untested work.

- scripts/README: description of what this is and of toolchain requirements
- scripts/build: build u-boot from scratch
- scripts/update: update one or both (upstream git and OM SVN) repositories

+u-boot build scripts
+====================
+
+This is a collection of scripts to build u-boot. This is the "manual" build
+process, which only needs a cross-toolchain, but nothing else from OpenEmbedded
+or any similar environment.
+
+They're mainly intended as examples for how the process works and aren't
+necessarily useful "as is" for daily work:
+
+build
+  Build u-boot from scratch, using either the latest or some specific
+  version from the u-boot upstream sources (git) and the OpenMoko patches
+  (SVN).
+
+update
+  Update the u-boot sources to either the latest or some specific version.
+
+
+Toolchain
+---------
+
+We use the OpenEmbedded EABI toolchain. Below is are instructions for a
+quick minimal setup for the purpose of building u-boot and the kernel.
+More detailed instructions can be found here:
+http://wiki.openmoko.org/wiki/Toolchain
+
+# If the host is 64 bit (x86_64):
+DL=http://downloads.openmoko.org/
+wget $DL/toolchains/openmoko-x86_64-arm-linux-gnueabi-toolchain.tar.bz2
+tar xCfj / openmoko-x86_64-arm-linux-gnueabi-toolchain.tar.bz2 
+
+# If the host is 32 bit (i686):
+DL=http://downloads.openmoko.org/
+wget $DL/toolchains/openmoko-i686-arm-linux-gnueabi-toolchain.tar.bz2
+tar xCfj / openmoko-i686-arm-linux-gnueabi-toolchain.tar.bz2 
+
+# Then set the PATH with:
+PATH=$PATH:/usr/local/openmoko/arm/bin
+
+
+Environment variables
+---------------------
+
+See "build".
