2014-12-08Kbuild: introduce Makefile in arch/$ARCH/Daniel Schwierzeck
Introduce a Makefile under arch/$ARCH/ and include it in the top Makefile (similar to Linux kernel). This allows further refactoringi like moving architecture-specific code out of global makefiles, deprecating config variables (CPU, CPUDIR, SOC) or deprecating arch/$ARCH/config.mk. In contrary to Linux kernel, U-Boot defines the ARCH variable by Kconfig, thus the arch Makefile can only included conditionally after the top config.mk.

2014-12-05powerpc/b4860qds: add workaround for XFIShaohui Xie
XFI does not work stable on current board, it's due to heat sink issue, to make it work stable the board needs additional heat sink, enable two XFI lanes only. Right now we do not have such an erratum for the issue, so use a define CONFIG_SYS_FSL_B4860QDS_XFI_ERR to identify it. The workaround will only be used in XFI protocols and only if the hwconfig indicates that XFI is prefered. A new VSC3308 config function is used instead of re-use the original function, to avoid making the function complex and ugly.

2014-11-21fdt: Allow ft_board_setup() to report failureSimon Glass
This function can fail if the device tree runs out of space. Rather than silently booting with an incomplete device tree, allow the failure to be detected. Unfortunately this involves changing a lot of places in the code. I have not changed behvaiour to return an error where one is not currently returned, to avoid unexpected breakage. Eventually it would be nice to allow boards to register functions to be called to update the device tree. This would avoid all the many functions to do this. However it's not clear yet if this should be done using driver model or with a linker list. This work is left for later.

U-Boot has imported various utility macros from Linux scattering them to various places without consistency.

Moreover, we are suffering from too cluttered include/common.h. This commit moves various macros that originate in include/linux/kernel.h of Linux to their original position.
