Re: AW: AW: AW: initrd rootfs ramdisk

Sigh...found it, after weeks of on-and-off work...  Our board has 64 MB of
RAM but I'm passing "mem=32M" to the kernel because we want our app to man-
age the high 32 MB.

U-Boot defaults to copying an initrd into the highest available RAM.  That
put it in an area outside of Linux's knowledge, D'OH.  All I had to do was
set U-Boot's 'initrd_high' env var and things work.

Note: if you want the  content  of  this  reserved  area  to  survice
warmboots  you  can  enable  the  "protected  RAM"  feature in U-Boot
(CONFIG_PRAM), and it will not touch this area  at  all.  Useful  for
things like pramfs for example :-)
