[U-Boot] [U-boot] regression: bootaux doesn't work with DCACHE enabled

[Igor Opaniuk]

Hi all,

U-boot imx-specific bootaux command doesn't work properly
with the old legacy binary format if the DCACHE is enabled (I've
tested only executing from OCRAM) in the mainline U-boot.

Interesting thing is that invocation of `dcache flush` before bootaux
doesn't help, but only full disabling it with `dcache off`.

To reproduce:
> tftpboot ${loadaddr} ${board_name}/hello_world.bin
> cp.b ${loadaddr} 0x7F8000 $filesize
> bootaux 0x7F8000

However this works:
> tftpboot ${loadaddr} ${board_name}/hello_world.bin
> cp.b ${loadaddr} 0x7F8000 $filesize
> dcache off
> bootaux 0x7F8000

Any ideas and suggestions?
Thanks
