+*********************************************************************
+Steps to build the kernel:
+
+Download and install the cross toolchain gcc version 4 for Linux 2.6.
+
+$ cd /opt
+$ tar xjf mipseltools-gcc412-glibc261.tar.bz2
+$ export PATH=/opt/mipseltools-gcc412-glibc261/bin:$PATH
+
+Download the linux kernel tarball linux-2.6.24.3.tar.bz2 and unpack it:
+
+$ tar xjf linux-2.6.24.3.tar.bz2
+
+Download the latest kernel patch and patch it to the kernel tree:
+
+$ cd linux-2.6.24.3
+$ gzip -cd ../linux-2.6.24.3-jz-yyyymmdd.patch.gz | patch -p1
+
+Make defconfig of the JZSOC based platform, eg:
+
+$ make apus_defconfig	(JZ4750 based APUS board)
+or
+$ make pavo_defconfig	(JZ4740 based PAVO board)
+or
+$ make pmp_defconfig	(JZ4730 based PMP board)
+
+Build the kernel:
+
+$ make xconfig
+$ make uImage
+or
+# make zImage
+or
+# make modules

+linux-2.6.24.3-jz-20090226.patch.gz
+
+  * Fixed a bug of YAFFS2 on JZ4750 when using BCH ECC algorithm.
+    
+linux-2.6.24.3-jz-20090218.patch.gz
+
+  * Support Jz4750
+  * Converted MTD from 32bit to 64bit to support the NAND larger than 2GB, and yaffs2 was 
+    modified accordingly.
+  * Supported multi-plane operation and multiply chip selecting for NAND flash. 
+  * Whether NAND multiple planes operation for one partition is used or not could be 
+    determined by the value of use_planes in partition_info[] in drivers/mtd/nand/jz47xx_nand.c
+  * Modified yaffs2 utils mkyaffs2image to support writting 4KB pagesize NAND and enable 
+    writing soft reed-solomn ECC for yaffs2 file system information in oob area of MLC nand
+
+linux-2.6.24.3-jz-20080926.patch.gz:
+
+  * Fixed a fatal bug for mplayer, which may cause some files cannot be played and the system is crashed.
+    Updated file: arch/mips/jz4740/proc.c.
+  * Modify jzfb_mmap() for cacheable LCD framebuffer access.
+
+linux-2.6.24.3-jz-20080815.patch.gz:
+
+  * Modify ipu interface to toggle PID of MPlayer in TLB.
+  * Modify OSS ioctl function to play movie with mono channel better. 
+  * Check whether the free block of nand is erased before erasing it, 'unsigned int' instead of
+    'unsigned short' was used to store block number, and heap sort for lifetime after 
+     erasing a block was replaced by another faster method.
+  * Cache read was used in nand_read_page_hwecc_rs() for Jz4740.
+  * Faster timing in REG_EMC_SMCR1 whose value is 0x09221200 was used.
+  * Supported 4KB page size nand
+  * Soft reed solomon ECC was supported for yaffs2 information which is 16 bytes in nand 
+    oob, and it should be used for MLC nand.
+  * Added support to generate any frequency baud rate of uart for both Jz4740 and Jz4750.
+  * Modified Jz4750's INTC, CIM, TSSI, macros.
+  * Combined Jz4750 SLCD Controller support into drivers/video/jz4750_lcd.c, which now support
+    LCD Controller, Slcd Controller and TVE. And add smart lcd panel TRULY_TFT_GG1P0319LTSW_W support.
+  * Add Jz4750 LCDC and TVE driver. 
+  * Modified CONFIG_FB_JZXXX macros, rename drivers/video/jzslcd.x to drivers/video/jz4740_slcd.x
+  * Add jz_clocksource, upgrade the system time's accuracy from 10ms to about 1(or 2) us.
+    but the system timer remained 10ms.
+  * Updated UBIFS.
+
+linux-2.6.24.3-jz-20080530.patch.gz:
+
+  * Added JZ4720 virgo board support.
+  * Added definition of CONFIG_SOC_JZ4725 and CONFIG_SOC_JZ4720.
+  * Added selection of 4-bit/1-bit data bus for MMC/SD card driver.
+  * Added dipper_defconfig for JZ4725 DIPPER board.
+  * Modified sound/oss/jz_i2s.c to increase the sound buffer.
+  * Modified pavo_defconfig to select the oss sound driver by default.
+  * Fixed jzlcd.h for jz4730 pmp.
+  * Modified jzcs8900a.c to not test the chip ID.
+
+linux-2.6.24.3-jz-20080526.patch.gz:
+
+  * Rewrote all of the UBI and UBIFS codes and their utilities.
+  * Modified MMC/SD driver jz_mmc.c to support PM callback.
+  * Fixed a bug of mtdblock-jz.uu of using the badblock_table.
+  * Patch jz4740_nand.c to optimize the RS correction algorithm.
+  * Jzlcd driver added framebuffer rotation support.
+
+linux-2.6.24.3-jz-20080422.patch.gz:
+
+  * Supported multi-framebuffers LCD driver.
+  * Modified sound/soc/jz4740/jz4740-i2s.c to support 32KHz PCM sample.
+  * Ported new mtd-utils and mkfs.ubifs.
+  * Added jzslcd.c for Smart LCD framebuffer driver.
+  * Modified rtc_jz.c to use some functions in rtc library instead of our function.
+  * Added jz_keypad.c and gpio_keys.c for scan keypad drivers.
+  * Added block-jz.c to support block device layer on top of ubi.
+  * Modified jz4740_udc.c to enable the suspend irq when host unloads us.
+  * pavo_defconfig: select CONFIG_WIRELESS_EXT, CONFIG_PNP and CONFIG_SERIAL_8250_PNP.
+  * Modified jz_ts.c jz_ts.h and sadc.c to release CPU by interrupt mode instead of pio mode.
+  * Fixed a bug in jz4740_udc.c and jz4730_udc.c during rmmod the driver.
+  * Modified jz_i2s.c to fix the jz_audio_release().
+  * Fixed udc_hotplug.c to avoid the "unexpected IRQ".
+  * Fixed jz4740/cpufreq.c of calculating the new_mclk.
+  * Modified drivers/video/console/fbcon.c by adding fb_flashcursor selection.
+
+linux-2.6.24.3-jz-20080304.patch.gz: 
+
+  * First full release, support JZ4740 PAVO and JZ4730 PMP boards.
+  * Some important drivers: YAFFS2, UBI & UBIFS, Power management,
+    SLC/MLC NAND, MMC/SD, LCD framebuffer, ALSA/OSS audio, UDC,
+    USB host, Camera, RTC, WatchDog, udev, hotplug etc.
