From: Dalon Westergreen <dalon.westergreen@intel.com>

Stratix10 requires a hex image of the spl plus spl devicetree offset to
the Stratix10 onchip memory located at SPL_TEXT_BASE.  This patch adds
a target to generate a hex file from the u-boot-spl binary including the
dtb offset at SPL_TEST_BASE.

Objcopy is used to convert the $(SPL_BIN).bin, which includes the spl
dtb, to a hex file.  the --change-address option is used to offset the
hex to SPL_TEXT_BASE as objcopy on the spl binary will not result in
a hex file appropriately offset at SPL_TEXT_BASE.

---
Changes in v3:
 -> Cleanup commit message and better describe the problem being
    resolved
 -> Remove extraneous hunk
 -> use SPL_BIN instead of u-boot-spl
Changes in v2:
 -> Move spl hex file generation to SPL Makefile
 -> Create hexfile from $(SPL_BIN).bin which will include the dtb
    ifneq(build_dtb,)

SoCFPGA folks?  This has been posted a few times, is this OK for the
next release?  Thanks

While I like the idea of this patch, and I *think* that this is what an 
SPL hex should look like for all platforms, I'm not 100% sure that 
globally changing the rule and objcopy flags for u-boot-spl.hex is OK 
for all architectures?

Let's try to apply this at the start of next merge window, then we'll 
hopefully see if this does break any board.

sounds good, i dont believe there are other boards with SPL hex as atarget, at

Even better. Sadly, the Quartus gen5 tools require the HEX to be at offset 0
to create a 'boot-from-FPGA' image, but since that one is easy enough to
create without Makefile help, I think this patch is still ok.
