The peach boards have their SDRAM start address at 0x20000000 instead of
0x40000000 which seems common for all other exynos5 based boards. This
means the layout set in exynos5-common.h causes the kernel be loaded
more then 128MB (at 0x42000000) away from memory start which breaks
booting kernels with CONFIG_AUTO_ZRELADDR

Define a custom MEM_LAYOUT_ENV_SETTINGS for both peach boards which uses
the same offsets from start of memory as the common exynos5 settings.

This fixes booting via bootz and PXE

It would be great if we could have this in the device tree.

I haven't merged this patch yet, but it goes some of the way:

I think it would be awesome to have this via device tree as well as that
would be another step closer to allowing one u-boot binary for a group
of boards. However, that's clearly much more work. So for the short term
(and ideally the coming release)  i'd quite prefer this minimal change
to go in to unbreak bootz  and PXE on these boards.

I understand what you're thinking but this is environment.  And really
this is not board specific, this is SoC family specific which is why the
similar part for TI stuff is in ti_armv7_common.h :)

Exynos 5 has the same in exynos5-common.h, however for whatever reason
the peach pi/pit boards are different then other exynos board supported
by u-boot thusfar. So in this case, this information _is_ board specific
not platform specific.

But even in case of including it in device tree, a default/common
setting could go into the platforms dtsi with board-specific overrides
as needed.

One thing i have wondered though, looking at the various boards
specifying the various memory layour addresses. They all end up being
relatively similar offset to the base memory address, which makes me
think it may be possible to calculate these values in the initialisation
code rather then having to hardcode it in the environment. However, even
if that's a sensible thing, something for later :)

Oh I missed that early on, sorry.  But...

Why not change things around a bit to enable CONFIG_CMD_SETEXPR and then
have MEM_LAYOUT_ENV_SETTINGS just set the exynos5_ddr_base and then
setexpr kernel_addr_r $exynos5_ddr_base + 0x2000000
and similar in the generic part.

... Yes, we should then take what I just did above and make it even
further wide-spread among boards where we have more than ~512MB DDR or
so :)

Partially because i didn't know the setexpr command and partially
because i wanted a minimally disruptive patch that can hopefully still
make it for 2015.4. 

I think doing the above would also require tweaking the distro_boot_cmd
code to integrate it nicely.

Sounds like a plan.

For the first part I forgot it existed until this morning so that's OK
:)

I'm agreeable to taking this now to fix things if we promise to clean it
up ASAP after the release (since we can do that without breaking the
visible portion I think).

I'm ok to prepare some patches for polishing this in the next few weeks
as it peeked my interests.
