* arm: exynos7420: remove custome low level init functionThomas Abraham2016-11-22-8/+11
| | | | | | | | | | | | | | | | | Remove the custom low-level initialization function and reuse the default low-level initialization function. But this requires the ARMV8_MULTIENTRY config option to be enabled for Exynos7420. On Exynos7420, the boot CPU belongs to the second cluster and so with ARMV8_MULTIENTRY config option enabled, the 'branch_if_master' macro fails to detect the CPU as boot CPU. As a temporary workaround the CPU_RELEASE_ADDR is set to point to '_main'.

* ARM: Rework and correct barrier definitionsTom Rini2016-08-05-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of testing booting Linux kernels on Rockchip devices, it was discovered by Ziyuan Xu and Sandy Patterson that we had multiple and for some cases incomplete isb definitions. This was causing a failure to boot of the Linux kernel. In order to solve this problem as well as cover any corner cases that we may also have had a number of changes are made in order to consolidate things. First, <asm/barriers.h> now becomes the source of isb/dsb/dmb definitions. This however introduces another complexity. Due to needing to build SPL for 32bit tegra with -march=armv4 we need to borrow the __LINUX_ARM_ARCH__ logic from the Linux Kernel in a more complete form. Move this from arch/arm/lib/Makefile to arch/arm/Makefile and add a comment about it. Now that we can always know what the target CPU is capable off we can get always do the correct thing for the barrier. The final part of this is that need to be consistent everywhere and call isb()/dsb()/dmb() and NOT call ISB/DSB/DMB in some cases and the function names in others.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear away the ugly logic in include/fdtdec.h: #ifdef CONFIG_OF_CONTROL # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL) # define OF_CONTROL 0 # else # define OF_CONTROL 1 # endif #else # define OF_CONTROL 0 #endif Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for SPL. Also, we no longer have to cancel CONFIG_OF_CONTROL in include/config_uncmd_spl.h and scripts/Makefile.spl.
