[PATCH u-boot-marvell 4/5] tools: kwboot: Replace ARM mov + movt instruction pair by mov + orr

[Marek Behún]

From: Pali Rohár <pali at kernel.org>

Older Armada SoCs have custom ARMv5te compatible core which does not
support movt instruction. So replace mov + movt instruction pair used for
immediate move construction by mov + orr instructions which are supported
also by ARMv5te.

After this change kwboot ARM code should be compatible with any 32-bit ARM
core compatible by ARMv2 or new. At least GNU AS does not throw any error
or warning.
