Here is a linker's error message for some configurations:
or1k-elf-ld: barebox section `.eh_frame' will not fit in region `ram'
or1k-elf-ld: region `ram' overflowed by 16868 bytes
This patch increases space reserved for barebox from 256K to 512K
so the error's probability is dramatically

This patch series adds device tree support for openrisc generic board.
The barebox mips device tree support is used as a sample.
Changes since v1:
* rebase over latest next;
* add 'Documentation: add OpenRISC or1ksim emulator section'.

There are some minor changes with original linux-3.16 file:
* the 'model' attribute is added (it used for barebox banner board name);
* all opencores,*-rtlsvn* 'compatible' attribute values are dropped;
these values are not actually used in the device drivers.

Hi!
Changes since v3:
- minor clean up
- add binding documentation in 5/5
- rebase to v2014.09.0

Unfortunately the transition to pinctrl for AT91 caused some damage.
The 926x do not compile anymore. Even when this is fixed the boards
won't work since the new pinctrl driver uses of_alias_get_id() even
for the platform case to translate the device into a gpio chip.
Sascha
the gpio mux functions were moved to mach/gpio.h. Add the missing
include.

Could you explain what exactly this patch fixes? It seems without this
patch the pinctrl part is non functional. Is this correct?
