Linux - Change the location of a linux fs in flash

Hello, does anybody know how to change the location of the linux romfs in flash. I have a small custom board with only 1 MByte flash "available" and therefor i'm currently running my kernel directly from SDRAM (just while i'm testing). How do I change the location of the romfs to begin from addr. 0x0 (in flash) instead of 0x200000???

I&#39;ve modified the location_on_target in <filesystem>.stf to the following:

<location_on_target offset=&#39;0x0&#39;>

then i&#39;ve modified the following lines in asm-offsets.c:

from:

DEFINE(KERNEL_FLASH_START, na_flash_kernel);

to:

DEFINE(KERNEL_FLASH_START, na_flash_kernel+0x200000);

from:

DEFINE(LINUX_ROMFS_START, na_flash_kernel+0x200000);

to:

DEFINE(LINUX_ROMFS_START, na_flash_kernel+0x0);

from:

DEFINE(LINUX_ROMFS_END, na_flash_kernel_end);

to:

DEFINE(LINUX_ROMFS_END, na_flash_kernel+0x200000);

but still I get the following kernel panic error:

Using deadline io scheduler
microtronix: RAM probe address=0x200000 size=0x4005000
Creating 1 MTD partitions on "RAM":
0x00000000-0x04005000 : "ROMfs"
microtronix: set ROMfs to be root filesystem
Kernel panic: VFS: Unable to mount root fs on mtdblock0

I guess it&#39;s got something to do with the very large address 0x04005000 but where it comes from I do not know......weird!

The custom board contains: 16Mbit flash (<-unfortunately on the test-board i&#39;m working with the highest address pin from the flash are NOT connected to the Nios II - processor, so for now i&#39;m just running it as a 1MByte flash)/2MByte SDRAM/Cyclone EP1C6/LAN91C113 (<-the same as LAN91C111, but it only operates in 16bit mode)

Hope you can help me!
