As a matter of fact, it's really slow to tar -xf .tar file, compared
with my 2440 demo board.
I takes me half a day to unzip the file system to sd card with fso
image.
If it's with my demo board to unzip, very quick, about 10min or so.
What's wrong with fso image to unzip the tar package?

You could always use the .tar.gz on an sd card ( It boots way faster

NAND flash ought to be a lot faster than Glamo's MMC interface. Where is
the bug? FWIW, I tried a simple hdparm run on NOR flash, NAND flash and SD
card:
r...@debian-gta02:~# hdparm --direct -t /dev/mtdblock0# NOR flash
/dev/mtdblock0:
Timing O_DIRECT disk reads:2 MB in 1.24 seconds = 1.61 MB/sec
r...@debian-gta02:~# hdparm --direct -t /dev/mtdblock3# NAND flash
/dev/mtdblock3:
Timing O_DIRECT disk reads:8 MB in 2.89 seconds = 2.77 MB/sec
r...@debian-gta02:~# hdparm --direct -t /dev/mmcblk0 # Glamo MMC
/dev/mmcblk0:
Timing O_DIRECT disk reads:8 MB in 3.46 seconds = 2.31 MB/sec
