Hi!

We use ADV7181B and CCD camera to do the capture task.

But , now we have a problem.

In function of bcap_open()

bottom_buffer = (unsigned char *)0x1000;

CONFIG_BOOT_LOAD also is 0x1000;

So,

if ((bottom_buffer == (unsigned char *)0x1000) &&

     ((bottom_buffer + MAX_BUFFER_SIZE) >=

      (unsigned char *)CONFIG_BOOT_LOAD)) {

  printk(KERN_ERR ": couldn't allocate bottom buffer -"

         " kernel start address too low\n");

We couldn't allocate bottom buffer,kernel start address too low.
