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.

2016-06-26common: Pass the boot device into spl_boot_mode()Marek Vasut
The SPL code already knows which boot device it calls the spl_boot_mode() on, so pass that information into the function. This allows the code of spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets board_boot_order() correctly alter the behavior of the boot process. The later one is important, since in certain cases, it is desired that spl_boot_device() return value be overriden using board_boot_order().

PSCI stack setup is the only part left completely in assembly. In theory this part could be split out of psci_arch_init into a separate common function, and psci_arch_init could be completely in C.

2016-06-20ARM: allocate extra space for PSCI stack in secure section during link phaseChen-Yu Tsai
The PSCI implementation expects at most 2 pages worth of space reserved at the end of the secure section for its stacks. If PSCI is relocated to secure SRAM, then everything is fine. If no secure SRAM is available, and PSCI remains in main memory, the reserved memory space doesn't cover the space used by the stack. If one accesses PSCI after Linux has fully booted, the memory that should have been reserved for the PSCI stacks may have been used by the kernel or userspace, and would be corrupted. Observed after effects include the system hanging or telinit core dumping when trying to reboot. It seems the init process gets hit the most on my test bed. This fix allocates the space used by the PSCI stacks in the secure section by skipping pages in the linker script, but only when there is no secure SRAM, to avoid bloating the binary. This fix is only a stop gap. It would be better to rework the stack allocation mechanism, maybe with proper usage of CONFIG_ macros and an explicit symbol.

Sometimes this header may only be a few bytes of information, and sometimes this might simply be space that needs to be reserved for a post-processing tool. Introduce a config option to allow assembler preprocessor commands to be inserted into the code at the appropriate location; typical assembler preprocessor commands might be: .space 1000 .word 0x12345678 Signed-off-by: Andre Przywara <andre.przywara@arm.com> Signed-off-by: Steve Rae <srae@broadcom.com> Commit Notes: Please note that the current code: start.S (arm64) and vectors.S (arm) already jumps over some portion of data already, so this option basically just increases the size of this region (and the resulting binary). For use with Allwinner's boot0 blob there is a tool called boot0img[1], which fills the header to allow booting A64 based boards. For the Pine64 we need a 1536 byte header (including the branch instruction) at the moment, so we add this to the defconfig.
