* ARM: armv7: move CONFIG_ARMV7_PSCI to KconfigMasahiro Yamada2016-09-07-0/+1
| | | | | | | | | Add ARCH_SUPPORT_PSCI as a non-configurable option that platforms can select. Then, move CONFIG_ARMV7_PSCI, which is automatically enabled if both ARMV7_NONSEC and ARCH_SUPPORT_PSCI are enabled.

| * ARM: uniphier: display revision of Micro Support Card 3.6.x kindlyMasahiro Yamada2016-08-28-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The revision of the original support card (rev 3.5, rev 3.6) fits in the 8 bit width revision register. When it was extended in a weird way, it was versioned in the format of "3.6.x" (where it should have been "3.7", of course). What is worse, only the sub-level version "6.x" was recorded in the 8 bit width register, completely ignoring the compatibility of the revision register format. This patch saves madly-versioned support cards by assuming the major version "3" when the MSB 4 bit of the register is read as "6". With this, the support card revision that were displayed as "6.10" is now corrected to "3.6.10". Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
| * ARM: uniphier: support system reset functionality for PSCIMasahiro Yamada2016-08-28-2/+17
| | | | | | | | | | | | | | | | | | | | This supports the system reset via PSCI for ARMv7 SoCs. Because the system reset is not supported on PSCI 0.1, let's define CONFIG_ARMV7_PSCI_1_0. (it is supported since PSCI 0.2, but there is no CONFIG to enable it in U-Boot for now.) Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

* | ARM: Move SYS_CACHELINE_SIZE over to KconfigTom Rini2016-08-26-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This series moves the CONFIG_SYS_CACHELINE_SIZE. First, in nearly all cases we are mirroring the values used by the Linux Kernel here. Also, so long as (and in this case, it is true) we implement flushes in hunks that are no larger than the smallest implementation (and given that we mirror the Linux Kernel, again we are fine) it is OK to align higher. The biggest changes here are that we always use 64 bytes for CPU_V7 even if for example the underlying core is only 32 bytes (this mirrors Linux). Second, we say ARM64 uses 64 bytes not 128 (as found in the Linux Kernel) as we do not need multi-platform support (to this degree) and only the Cavium ThunderX 88xx series has a use for such large alignment.

* ARM: uniphier: move lowlevel debug init code after page table switchMasahiro Yamada2016-08-11-4/+4
| | | | | | | | | As the sLD3 Boot ROM has a complex page table, it is difficult to set up the debug UART with enabling it. It will be much easier to initialize the UART port after switching over to the straight-mapped page table. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: fix ROM boot mode for PH1-sLD3Masahiro Yamada2016-08-11-0/+5
| | | | | | | | | | | | | | Commit 4b50369fb535 ("ARM: uniphier: create early page table at run-time") broke the ROM boot mode for PH1-sLD3 SoC, because the run-time page table creation requires the outer cache register access but the page table in the sLD3 Boot ROM does not straight-map virtual/physical addresses. The idea here is to check the current page table to determine if it is a straight map table. If not, adjust the outer cache register base.

* ARM: uniphier: refactor L2 zero-touching code in lowlevel_initMasahiro Yamada2016-08-11-26/+22
| | | | | | | Here, the ldr pseudo-instruction falls into the ldr + data set. The register access by [r1, #offset] produces shorter code. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: do not compile v7_outer_cache_disable if L2 is disabledMasahiro Yamada2016-08-11-1/+1
| | | | | | | | If CONFIG_UNIPHIER_L2CACHE_ON is undefined, the L2 cache is never enabled, so there is no need for v7_outer_cache_disable(). The weak stub avoids the compile error anyway. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: support prefetch and touch operations for outer cacheMasahiro Yamada2016-08-11-10/+57
| | | | | | | | | | The UniPhier outer cache (L2 cache on ARMv7 SoCs) can be used as SRAM by locking ways. These functions will be used to transfer the trampoline code for SMP into the locked SRAM. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: refactor outer cache codeMasahiro Yamada2016-08-11-47/+52

* ARM: uniphier: use (devm_)ioremap() instead of map_sysmem()Masahiro Yamada2016-07-24-21/+19
| | | | | | | | This does not have much impact on behavior, but makes code look more more like Linux. The use of devm_ioremap() often helps to delete .remove callbacks entirely. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

* ARM: uniphier: add external IRQ setup codeMasahiro Yamada2016-07-02-0/+44
| | | | | | | | I will carry this work-around until it is cared in the kernel. This looks up the AIDET node and sets up a register to handle active low interrupt signals. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

* common: Pass the boot device into spl_boot_mode()Marek Vasut2016-06-26-1/+1
| | | | | | | | | | | | | | | | | | 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().

* ARM: uniphier: reserve memory for DRAM PHY training on PH1-LD20Masahiro Yamada2016-06-20-0/+41
| | | | | | | | | | | | | | | | | | 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>

* ARM: uniphier: insert dsb barrier to ensure visibility of storeMasahiro Yamada2016-06-09-2/+2
| | | | | | | | | | | | I noticed secondary CPUs sometimes fail to wake up, and the root cause is that the sev instruction wakes up slave CPUs before the preceding the register write is observed by them. The read-back of the accessed register does not guarantee the order. In order to ensure the order between the register write and the sev instruction, a dsb instruction should be executed prior to the sev. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
