[ELDK] Modifying Load Location of Ramdisk

[Jonathan Haws]

All,

I need to modify the load location of the Ramdisk.  It is loading into memory that I need to reserve for DMA operations.  Is there a parameter in the Makefile of the RFSB or a parameter that I can pass to mkimage to handle that?  If not, how can it be done?

Thanks!

Jonathan


Here is the output of U-Boot when it unpacks the images.  It load the Ramdisk to 0x0FC73000.  I need to have it unpack to 0x0EC00000, that would be perfect (that gives the Ramdisk 4 MB of space below my DMA operations zone).

Any help is appreciated!
