* ARM: uniphier: add PLL init code for LD11 SoCMasahiro Yamada2016-09-23-7/+71
| | | | | | | | | | - Initialize PLLs (SPL initializes only DPLL to save the precious SPL memory footprint) - Adjust CPLL/MPLL to the final tape-out frequency - Set the Cortex-A53 clock to the maximum frequency since it is running at 500MHz (SPLL/4) on startup Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: move CONFIG_SPL_* to defconfig or selectMasahiro Yamada2016-09-23-15/+0
| | | | | | | | | | | | As I repeated in the ML, I am unhappy with config entries with bare defaults. Kick them out of arch/arm/mach-uniphier/Kconfig. Currently, CONFIG_SPL_SERIAL_SUPPORT is not user-configurable (build fails without it), but it should be fixed later anyway, so I am moving CONFIG_SPL_SERIAL_SUPPORT to defconfigs.

| * ARM: uniphier: add PLL init code for LD20 SoCMasahiro Yamada2016-09-19-5/+234
| | | | | | | | | | | | | | | | Initialize the DPLL (PLL for DRAM) in SPL, and others in U-Boot proper. Split the common code into pll-base-ld20.c for easier re-use. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
| * ARM: uniphier: collect clock/PLL init code into a single directoryMasahiro Yamada2016-09-19-24/+18
| | | | | | | | | | | | | | | | Now PLLs for DRAM controller are initialized in SPL, and the others in U-Boot proper. Setting up all of them in a single directory will be helpful when we want to share code between SPL and U-Boot proper. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

| | | | | | | | | | | | | | | | | | Unfortunately, this SoC needs per-board adjustment between clock and address/command lines.

| * ARM: uniphier: merge board init functions into board_init()Masahiro Yamada2016-09-14-40/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the UniPhier platform calls several init functions in the following order: [1] spl_board_init() [2] board_early_init_f() [3] board_init() [4] board_early_init_r() [5] board_late_init() The serial console is not ready at the point of [2], so we want to avoid using [2] from the view point of debuggability. Fortunately, all of the initialization in [2] can be delayed until [3]. I see no good reason to split into [3] and [4]. So, merge [2] through [4].

| * 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>

| | | | | | | | | | | | | | | | | | | | 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: 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.
