[PATCH 2/9] ARM s3c boards: Do not hardcode image sizes

[Sascha Hauer]

The existing nand_boot functions all do the same, so move it to
a common place. To be flexible enough for future boards the real
image size is used instead of hardcoded 256k.

[PATCH 5/9] ARM: fix netx/MLO/s5p image build for pbl

[Sascha Hauer]

If pbl support is enabled only zbarebox.bin was built, but
not the SoC specific images. Fix this.

yeah it does the trick but I do not like the makefile target
we need to create cmd and use the $(call xxx,ifchanged) mecanism

Can do, but this would be subject to another patch. This patch only changes
the dependencies, but not what is done.

agreed but as we touch it we really need to clean it
and do not add more as with the ln

[PATCH 6/9] ARM Makefile: generate a barebox-flash-image link

[Sascha Hauer]

Depending on the SoC a barebox.bin, barebox.netx, barebox.s5p, MLO image
is generated. With pbl support there now is an additional
arch/arm/pbl/zbarebox.bin image.

To help the user to determine which image should be flashed to his device,
generate a barebox-flash-image link.

as it's not arm specific

[PATCH 9/9] ARM pbl: generate zbarebox.map in $(obj)

All other linker generated files are there, too, so it seems logical
to put the map file there aswell.

[PATCH] pbl updates

[Sascha Hauer]

Here are two updates for the MMU code in the decompressor. The first
one may come in handy when a JTAG debugger is connected. The second
one is more important. It actually makes turning on the MMU in the
decompressor useful by making map_cachable work. It turned out that
this didn't work leaving the whole mapping uncached.
Note that the code in current master should work, but slow. Since
it actually does work I do not want to put this into the upcoming
release.

As I report the current code does not work on at91sam9g45
I suspect as we boot from the second ram controler on this SoC

So please hold the release that I can try those patch on sam9g45 if they fix
the PBL they will be mandatory for it

I think they won't fix it. map_cachable currently is a noop, but this
should be fine as now we have a complete 1:1 uncached mapping. I don't
see why this shouldn't work. I hope you find out.

What we can do for now is to add an additional Kconfig option to make
enabling the MMU in the pbl optional. Then at least it should work on
your boards.

BTW I hunted down a strange problem with the MMU on a KaRO Tx53 board.
It turned out that the image header (which basically is a poke table
to initialize the SDRAM) indeed initialized the SDRAM. The problem was
that this SDRAM setup depends on some other lowlevel setup which is done
later. The SDRAM setup was good enough to load with MMU disabled, but
once the MMU is enabled the SDRAM does burst accesses and the board goes
to nirvana.
Maybe your problem is related somehow.

Sascha

yeah It may solve my issue with the MMU and nand boot

I was thinking to add a initcall support to the pbl and enable the MMU at the
right momment. This will allow to simplify the adding of generic SPL framework

I don't think this is a good idea. I don't want to grow a second
bootloader in the pbl. It should stay simple.

I want to add spi boot and mmc boot where the non shell barebox is too big to
