[U-Boot-Users] New buildroot-atmel

Have updated my buildroot at ftp://at91dist:distrib@ -> AT91_Third_party..-> Linux_Host -> Source
to buildroot-atmel-2007-05-12.tar.bz2.
Also updated my u-boot 1.2.0 and dataflashboot so this needs to be deleted and reloaded from the ftp site.

Some fixes in u-boot:
1) NAND flash is now detected in my U-boot
2) SAM9263EK machine id set correctly.
3) Some cleanup of the "defenv" command
	The follwoing command sequence should boot the linux
	defenv			- generate your customized u-boot environment
	run config		- runs an autoscript wiuth further configuration
	run flash-kernel	- downloads the kernel to dataflash
	run flash-ramdisk	- downloads the ramdisk to dataflash
	run bootcmd		- start linux
4) Kernel space increased from 1.25 MB to 1.5 MB

Fixes in buildroot
1) Support for building with Andrews patches. This is now the default.
2) A script "netcfg.sh" which sets the U-boot default ipaddr/serverip/gatewayip
   for first time u-boot programming (See make_boards.sh)
3) A problem with nm getting linux symbols from the wrong file is fixed.
4) DataflashBoot-1.05 has been modified to avoid recompiling every time.
   A new download is needed.

Big Thanks to everyone pointing out problems.

Following issues remains:
u-boot seems to be recompiled every time make is done in buildroot.

The following issues in the linux boot:

"Ignoring unrecognised tag 0x54410008"
==> Anyone got a clue?

atmel_lcdfb: probe of atmel_lcdfb.0 failed with error -2
==> Driver seems only to support sam9261.

No NAND device found!!!
==> I think this is because I enabled OneNAND support.

usbmon: debugfs is not available
==> Is this an issue?

ads7846 spi0.3: external vREF for ADS7843 not specified
==> ???

ALSA device list:
  No soundcards found.

drivers/rtc/hctosys.c: unable to open rtc device (rtc0)

mount: can't find udev in /etc/fstab
==> This is quite serious.
    I enclose my fstab. Anyone with ideas what to modify

ip: RTNETLINK answers: File exists
==> Is this normal?

Full boot below.
