[U-Boot] [PATCH] igep00x0: enable CONFIG_CMD_SETEXPR

[Ladislav Michl]

Enable CONFIG_CMD_SETEXPR, useful when passing initramfs end address:
$ fatload mmc 0:1 $rdaddr root.cpio.gz
$ setexpr rdendaddr $rdaddr + $filesize
$ fdt chosen $rdaddr $rdendaddr
$ bootz $loadaddr - $fdtaddr

OK, but why do that instead of 'bootz $loadaddr $rdaddr $fdtaddr' ?

=> bootz $loadaddr $rdaddr $fdtaddr
Wrong Ramdisk Image Format
Ramdisk image is corrupt or invalid

Well, perhaps that could be done with CONFIG_SUPPORT_RAW_INITRD, which
expects size of initrd, not an end address. I'll give it a try and possibly
enable that instead.

Ok, works and is even already defined in ti_armv7_common.h and
'bootz $loadaddr $rdaddr:$filesize $fdtaddr' is even simpler. Thank you :)
