+*********************************************************************
+Steps to build the u-boot:
+
+Download and install the cross toolchain gcc version 4:
+
+$ cd /opt
+$ tar xjf mipseltools-gcc412-glibc261.tar.bz2
+$ export PATH=/opt/mipseltools-gcc412-glibc261/bin:$PATH
+
+Download the u-boot tarball u-boot-1.1.6.tar.bz2 and unpack it:
+
+$ tar xjf u-boot-1.1.6.tar.bz2
+
+Download the latest u-boot patch and patch it to the u-boot tree:
+
+$ cd u-boot-1.1.6
+$ gzip -cd ../u-boot-1.1.6-jz-yyyymmdd.patch.gz | patch -p1
+
+Make defconfig of the JZSOC based platform, eg:
+
+$ make apus_nand_config (NAND boot for JZ4750 APUS board)
+
+$ make pavo_config (NOR boot for JZ4740 PAVO board)
+or
+$ make pavo_nand_config (NAND boot for JZ4740 PAVO board)
+
+$ make pmpv2_config (NOR boot for JZ4730 PMP Ver 2.x board)
+or
+$ make pmpv2_nand_config (NAND boot for JZ4730 PMP Ver 2.x board)
+
+Build the u-boot:
+
+$ make
+
+Then burn the u-boot-nand.bin (for NAND flash) or u-boot.bin (for NOR flash)
+to the target board by using JDI or USB boot tool.
