* ARM: uniphier: add PLL init code for LD11 SoCMasahiro Yamada2016-09-23-2/+4
| | | | | | | | | | - 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: add PLL init code for LD20 SoCMasahiro Yamada2016-09-19-2/+4
| | | | | | | | 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: move PLL init code to U-Boot proper where possibleMasahiro Yamada2016-09-19-24/+16
| | | | | | | | The PLL for the DRAM interface must be initialized in SPL, but the others can be delayed until U-Boot proper. Move them from SPL to U-Boot proper to save the precious SPL memory footprint. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: consolidate System Bus pin-mux settings for LD11/LD20Masahiro Yamada2016-09-18-3/+4
| | | | | | | Use the pin-mux data in the pinctrl drivers by directly calling pinctrl_generic_set_state(). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: remove ad-hoc pin-mux code for sLD3Masahiro Yamada2016-09-18-2/+0
| | | | | | These settings are nicely cared by the pinctrl driver now. Remove. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: add PH1-LD11 SoC supportMasahiro Yamada2016-05-26-0/+65
| | | | | | This is a low-cost ARMv8 SoC from Socionext Inc. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: disable cache in SPL of PH1-LD20Masahiro Yamada2016-05-26-0/+2
| | | | | | | | The Boot ROM has enabled D-cache and MMU setting DDR memory area as Normal Memory in its page table. Disable D-cache and MMU before jumping to U-Boot proper. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: move pin-mux code into pin_init functionMasahiro Yamada2016-05-01-3/+2
| | | | | | | The code in uniphier_sld3_sbc_init() is pin-muxing, so it would be a better fit in uniphier_sld3_early_pin_init(). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: allow to use System Bus for ROM boot mode of PH1-LD20Masahiro Yamada2016-05-01-0/+2
| | | | | | | | | The System Bus is not available by default on the ROM boot mode of PH1-LD20. To use devices connected to the System Bus, such as the Micro Support Card, it is necessary to set up pin-muxing and some System Bus Controller register.

* ARM: uniphier: add PH1-LD20 SoC supportMasahiro Yamada2016-04-24-0/+59
| | | | | | This is the first ARMv8 SoC from Socionext Inc. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: rename function names ph1_* to uniphier_*Masahiro Yamada2016-04-01-42/+42
| | | | | | | Eliminate the "ph1"_ prefixes from function names because "uniphier_" describes the SoC familiy better. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: support Debug UARTMasahiro Yamada2016-03-24-0/+5
| | | | | | | | | | | | For ARM32 architecture, CONFIG_DEBUG_LL is available for early low-level debugging (and actually UniPhier 32bit SoCs use it), but ARM64 architecture does not support it. Instead, CONFIG_DEBUG_UART is available as an architecture-independent debug facility. This commit supports it on all the UniPhier SoCs (including the new ARMv8 SoCs), which is very useful for new SoC bringups. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: refactor SBC init codeMasahiro Yamada2016-03-24-6/+10
| | | | | | | | | There is a bunch of duplication in the System Bus Controller init code. Roughly, there are two types in the SBC mode: Adress/Data Multiplex Mode and Save Pins Mode. Consolidate per-SoC functions into the two, plus per-SoC optional init code. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: drop PH1- prefix from CONFIG options and file namesMasahiro Yamada2016-03-24-21/+20
| | | | | | | | The current CONFIG names like "CONFIG_ARCH_UNIPHIER_PH1_PRO4" is too long. It would not hurt to drop "PH1_" because "UNIPHIER_" already well specifies the SoC family. Also, rename files for consistency. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: add DRAM init code for ProXstream2/PH1-LD6bMasahiro Yamada2016-01-13-0/+8
| | | | | | | | As mentioned in the log of commit 019df879a93e2 (ARM: uniphier: add ProXstream2 and PH1-LD6b support), the DRAM init code was missing for a long time. Finally, here it is. SPL works now. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: move headers out of include/mach directoryMasahiro Yamada2016-01-13-14/+21
| | | | | | | These headers are only included locally in arch/arm/mach-uniphier/. There is no reason to export them by putting in the mach/ directory. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: kill bogus header includesMasahiro Yamada2016-01-13-6/+0
| | | | | | These includes are not necessary. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: call uniphier_get_board_param() without FDT blobMasahiro Yamada2015-12-23-3/+1
| | | | | | | Move "gd->fdt_blob" from the caller to the callee so that this function can be used more easily. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* Various Makefiles: Add SPDX-License-Identifier tagsTom Rini2015-11-10-0/+4
| | | | | | | | | | | After consulting with some of the SPDX team, the conclusion is that Makefiles are worth adding SPDX-License-Identifier tags too, and most of ours have one. This adds tags to ones that lack them and converts a few that had full (or in one case, very partial) license blobs into the equivalent tag.

| | | | | | | The DDR SDRAM initialization code has not been mainlined yet, but U-Boot proper should work. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

* ARM: uniphier: allow to enable multiple SoCsMasahiro Yamada2015-09-25-0/+283
Before this commit, the Kconfig menu in mach-uniphier only allowed us to choose one SoC to be compiled. Each SoC has its own defconfig file for the build-test coverage. Consequently, some defconfig files are duplicated with only the difference in CONFIG_DEFAULT_DEVICE_TREE and CONFIG_{SOC_NAME}=y. Now, most of board-specific parameters have been moved to device trees, so it makes sense to include init code of multiple SoCs into a single image as long as the SoCs have similar architecture. In fact, some SoCs of UniPhier family are very similar: - PH1-LD4 and PH1-sLD8 - PH1-LD6b and ProXstream2 (will be added in the upcoming commit) This commit will be helpful to merge some defconfig files for better maintainability.
