Hello,

I have the following problem:
with buildroot-2011.11 I have generated file system, kernel (3.1.4) and 
u-boot. The board starts and everything works
fine except for one small flaw that bothers me. When starting the kernel 
providesthe following output:

...
at24 0-0050: 1024 byte 24c08 EEPROM, writable, 16 bytes/write
S3C24XX NAND Driver, (c) 2004 Simtec Electronics
s3c24xx-nand s3c2440-nand: Tacls=1, 9ns Twrph0=3 29ns, Twrph1=2 19ns
s3c24xx-nand s3c2440-nand: NAND soft ECC
NAND device: Manufacturer ID: 0xec, Chip ID: 0xd3 (Samsung NAND 1GiB 
3,3V 8-bit)
Creating 4 MTD partitions on "nand":
0x000000000000-0x000000040000 : "u-boot"
*uncorrectable error : *
0x000000040000-0x000000060000 : "u-boot-env"
*ftl_cs: FTL header not found.*

*ftl_cs: FTL header not found.*

Has anyone an idea how I can remove the bold warnings? These warnings 
seem to be generated by the file
linux-3.1.4/drivers/mtd/ftl.c (line 180).
Unfortunately I have no idea how I can fix this problem and hope for 
your expert help.
