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().

* Kconfig: Add a new DISTRO_DEFAULTS Kconfig optionHans de Goede2016-06-20-9/+0
| | | | | | | | | | | | | | | | | | | | | | 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. For testing and example purposes this commit also converts ARCH_SUNXI to use DISTRO_DEFAULT instead of selecting everything it needs itself. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
* sunxi: Add PSCI implementation in CChen-Yu Tsai2016-06-20-504/+341
| | | | | | | | | | | | | | To make the PSCI backend more maintainable and easier to port to newer SoCs, rewrite the current PSCI implementation in C. Some inline assembly bits are required to access coprocessor registers. 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.

* ARM: allocate extra space for PSCI stack in secure section during link phaseChen-Yu Tsai2016-06-20-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | For psci_get_cpu_stack_top() to be usable in C code, it must adhere to the ARM calling conventions. Since it could be called when the stack is still unavailable, and the entry code to linux also expects r1 and r2 to remain unchanged, stick to r0 and r3.

| * clk: convert API to match reset/mailbox styleStephen Warren2016-06-19-55/+204
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following changes are made to the clock API: * The concept of "clocks" and "peripheral clocks" are unified; each clock provider now implements a single set of clocks. This provides a simpler conceptual interface to clients, and better aligns with device tree clock bindings. * Clocks are now identified with a single "struct clk", rather than requiring clients to store the clock provider device and clock identity values separately. For simple clock consumers, this isolates clients from internal details of the clock API. * clk.h is split so it only contains the client/consumer API, whereas clk-uclass.h contains the provider API. This aligns with the recently added reset and mailbox APIs. * clk_ops .of_xlate(), .request(), and .free() are added so providers can customize these operations if needed. This also aligns with the recently added reset and mailbox APIs. * clk_disable() is added. * All users of the current clock APIs are updated. * Sandbox clock tests are updated to exercise clock lookup via DT, and clock enable/disable. * rkclk_get_clk() is removed and replaced with standard APIs. Buildman shows no clock-related errors for any board for which buildman can download a toolchain. test/py passes for sandbox (which invokes the dm clk test amongst others).

* | ARM: uniphier: reserve memory for DRAM PHY training on PH1-LD20Masahiro Yamada2016-06-20-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DRAM PHY layer on PH1-LD20 is able to calibrate PHY parameters periodically. This compensates for the voltage and temperature deviation and improves the PHY parameter adjustment. Instead, it requires 64 byte scratch memory in each DRAM channel for the dynamic training. The memory regions must be reserved in DT before jumping to the kernel. The scratch area can be anywhere in each DRAM channel, but the DRAM init code in SPL currently assigns it at the end of each channel. So, it makes sense to reserve the regions on run-time by U-Boot instead of statically embedding it in the DT in Linux. Anyway, a boot-loader should know much more about memory initialization than the kernel. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
