2016-07-14arm64: add better and more generic spin-table supportMasahiro Yamada
There are two enable methods supported by ARM64 Linux; psci and spin-table. The latter is simpler and helpful for quick SoC bring up. My main motivation for this patch is to improve the spin-table support, which allows us to boot an ARMv8 system without the ARM Trusted Firmware. Currently, we have multi-entry code in arch/arm/cpu/armv8/start.S and the spin-table is supported in a really ad-hoc way, and I see some problems: - We must hard-code CPU_RELEASE_ADDR so that it matches the "cpu-release-addr" property in the DT that comes from the kernel tree. - The Documentation/arm64/booting.txt in Linux requires that the release address must be zero-initialized, but it is not cared by the common code in U-Boot. We must do it in a board function. - There is no systematic way to protect the spin-table code from the kernel. We are supposed to do it in a board specific manner, but it is difficult to predict where the spin-table code will be located after the relocation. So, it also makes difficult to hard-code /memreserve/ in the DT of the kernel. So, here is a patch to solve those problems; the DT is run-time modified to reserve the spin-table code (+ cpu-release-addr). Also, the "cpu-release-addr" property is set to an appropriate address after the relocation, which means we no longer need the hard-coded CPU_RELEASE_ADDR.

2016-07-08armv8: Enable CPUECTLR.SMPEN for coherencyMingkai Hu
For A53, data coherency is enabled only when the CPUECTLR.SMPEN bit is set. The SMPEN bit should be set before enabling the data cache. If not enabled, the cache is not coherent with other cores and data corruption could occur. For A57/A72, SMPEN bit enables the processor to receive instruction cache and TLB maintenance operations broadcast from other processors in the cluster. This bit should be set before enabling the caches and MMU, or performing any cache and TLB maintenance operations.

DISTRO_DEFAULTS is intended to mirror / replace include/config_distro_defaults.h. The intend is for boards which include this file to select this from their Kconfig files and when moving setting to Kconfig which are #define-ed in config_distro_defaults.h to select this from DISTRO_DEFAULTS so that boards which have selected DISTRO_DEFAULTS will keep the same configuration as before without needing any defconfig file changes. The initial list of selected things matches all settings recently removed from config_distro_defaults.h because they have been converted to Kconfig, with the exception of CMD_ELF and CMD_NET, which have a default of y, if the default of these ever changes they should be selected by DISTRO_DEFAULTS too.
