booting lzma compressed linux uimage kernels worked fine on my Blackfin boards 
provided the malloc region was increased appropriately (lzma takes more mem 
than gzip or bzip2)

You can refer to Open-WRT Kamikaze ubootifx code to see how u-boot is
lzma'ed in flash and de-lzma'ed from flash to RAM....

Hi Prafulla,

This is my code to create the uimage:

# create flat binary
$(CROSS)objcopy -O binary -S $(LINUX_DIR)/vmlinux $(KDIR)/vmlinux.bin

# compress
$(TOOLS)/bin/lzma e $(KDIR)/vmlinux.bin $(KDIR)/vmlinux.lzma

# create uimage
export KERNEL_ENTRY=`$(CROSS)objdump -x $(LINUX_DIR)/vmlinux |grep -i
kernel_entry|cut -d " " -f 1` ;\
          mkimage -A mips -O linux -T kernel -C lzma -a 0x80010000 -e
$$$$KERNEL_ENTRY \
           -n 'IDF ONU BOARD Image-$(LINUX_VERSION)' \
           -d $(KDIR)/vmlinux.lzma $(KDIR)/uImage

I use everyday this script (picked from OpenWRT) to build my firmware image.

best regards,

luigi
