* ARM: uniphier: add dump command for DDR Multi PHY registersMasahiro Yamada2016-01-13-0/+339
| | | | | | | | The ProXstream2/PH1-LD6b is integrated with a new IP for DDR PHY which is not register-compatible with the former SoCs. Add a new command to support the register dump of this IP. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: add DRAM init code for ProXstream2/PH1-LD6bMasahiro Yamada2016-01-13-0/+826
| | | | | | | | 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: set DTB file name to fdt_file environmentMasahiro Yamada2015-12-23-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | When we want to boot Linux with a DTB file downloaded from a TFTP server or somewhere, we need to know the file name to be downloaded. Assume the U-Boot configuration is shared among some similar boards. If they are similar enough, the difference only appears in device trees. The build procedure would be like this: - Board A: make foo_common_defconfig && make DEVICE_TREE=foo_board_a - Board B: make foo_common_defconfig && make DEVICE_TREE=foo_board_b - Board C: make foo_common_defconfig && make DEVICE_TREE=foo_board_c In this case, the U-Boot image contains nothing about the DTB file name it is running with. (CONFIG_DEFAULT_DEVICE_TREE is not helpful for this purpose because it is painful to change it from "make menuconfig" for each board.) This commit allows to lookup the DTB file name based on the compatible string and set it to "fdt_file" environment. Then "tftpboot $fdt_file" will download the file we want.

* ARM: uniphier: merge umc/ and ddrphy/ into a single directoryMasahiro Yamada2015-12-23-15/+11
| | | | | | | | The UMC (Universal Memory Controller) and the DDR PHY block are highly related to each other. It is better to have both code in the same directory. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

* Various Makefiles: Add SPDX-License-Identifier tagsTom Rini2015-11-10-0/+48
| | | | | | | | | | | 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.

* ARM: uniphier: allow to enable multiple SoCsMasahiro Yamada2015-09-25-429/+1068
| | | | | | | | | | | | | | | | | | | | 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.

* ARM: uniphier: unify low-level debug init codeMasahiro Yamada2015-09-25-152/+115

* ARM: uniphier: fix glitch signal problem for low-level debugMasahiro Yamada2015-09-25-20/+20
| | | | | | | | | | | | | | | | | | | Currently, IECTRL is enabled after pin-mux settings for the low-level debugging for PH1-LD4 and PH1-sLD8. While IECTRL is disabled, input signals are pulled-down, i.e. glitch signal (Low to High transition) problem occurs if pin-mux is set up first. As a result, one invalid character is input to the UART block and the auto-boot counting is terminated immediately. The correct initialization procedure is: [1] Enable IECTRL (if IECTRL exists for the pins) [2] Set up pin-muxing [3] Deassert the reset of the hardware block Currently, the low-level debugging is working for PH1-sLD3 and PH1-Pro4, but just in case, follow the sequence for all the SoCs.

* ARM: uniphier: change the external bus address mappingMasahiro Yamada2015-09-25-19/+19
| | | | | | | | | | | | | | | | In UniPhier SoCs before ProXstream2 and PH1-LD6b, two address spaces 0x00000000 - 0x0fffffff 0x40000000 - 0x4fffffff are both mapped to the external bus (also called system bus), so either was OK. In the newest two SoCs, the former (0x00000000 - 0x0fffffff) is assigned for the serial NOR interface. Going forward, use the latter for the external bus.
