[U-Boot] [PATCH] config: peach: Correct memory layout environment settings
The peach boards have their SDRAM start address at 0x2000 instead of 0x4000 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 0x4200) 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.

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 :) -- Tom signature.asc Description: Digital signature ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

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 :) -- Sjoerd Simons Collabora Ltd. ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

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.

This means the layout set in exynos5-common.h causes the kernel be loaded more then 128MB (at 0x4200) 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.
