[PATCH u-boot-mvebu v2 18/41] tools: kwbimage: Add support for a new DATA_DELAY command

[Marek Behún]

From: Pali Rohár <pali at kernel.org>

This command is supported only by v1 images and specifies a milliseconds
delay after executing some set of DATA commands. The special string value
SDRAM_SETUP instructs BootROM to setup SDRAM controller instead of
executing delay. SDRAM_SETUP may be specified only once and after the
last DATA command.
