[PATCH v1 2/5] images: fix force rebuild of piggy.o

[Sam Ravnborg]

piggy.o would be build for every time barebox was built
This had the sideeffect that the image(s) would
always be rebuilt despite no changes

Fix this by adding piggy.o to targets
and avoid an extra command in the rule to create .pblb files

The patch includes the removal of a stray assignment

[PATCH v1 4/5] at91sam9263ek: fix build of of_init

[Sam Ravnborg]

Fix mistake in Makefile that prevented build of
of_init.o

With this fix smc shows up in iomem like this:

  0xffffe400 - 0xffffe5ff (size 0x00000200) at91sam9-smc0
  0xffffea00 - 0xffffebff (size 0x00000200) at91sam9-smc1

And we get access to the files from defaultenv provided by the board

[PATCH v1 5/5] video: mtl017: fix driver name variable

[Sam Ravnborg]

It look like a copy-paste bug that the twl_driver name
was used.
Rename to the more sensible mtl_driver

This adds multi images support, but the actual change that this patch
fixes came with 5a1a5ed253 ("ARM: images: use piggydata").

I changed that while applying.

Thanks,

I had to drop this one as it breaks compilation on some boards. Some
boards need r0 from the ROM so they have:

void __naked __bare_init barebox_arm_reset_vector(uint32_t *data)

We have to harmonize these first. I suggest to use

void __naked __bare_init barebox_arm_reset_vector(uint32_t r0, uint32_t r1, uint32_t r2)

Sorry - I did not test more than a few boards.

Like the prototype we have for the multi images.
I added this to the TODO list in the doc I just posted.

Don't worry, that's what my compile tests are good for.
