* ARM: uniphier: fix makefiles to build cmd_ddr(m)phy.cMasahiro Yamada2016-02-14-1/+8
| | | | | | | | The U-Boot proper building needs to descend arch/arm/mach-uniphier/dram to build these commands. Fixes: 93d92d46cd01 ("ARM: uniphier: add dump command for DDR Multi PHY registers") Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: remove unused header mio-regs.hMasahiro Yamada2016-02-14-20/+0
| | | | | | | | | This header is no longer used. This is the last file in arch/arm/mach-uniphier/include/mach/. At last, I've succeeded in eliminating the mach directory. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: drop unneeded EHCI pin mux settingsMasahiro Yamada2016-02-14-25/+0
| | | | | | | These pin mux settings are cared by the pinctrl drivers. Remove the ad-hoc code. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: switch over to generic EHCI driverMasahiro Yamada2016-02-14-8/+8
| | | | | | | | | | | | The UniPhier EHCI driver (drivers/usb/host/ehci-uniphier.c) does nothing special but set the base address and handle reset/clock. Since commit 4feefdcfe916 ("usb: add clock support for generic EHCI"), the generic one (drivers/usb/host/ehci-generic.c) can do those, too. We no longer need to stick to the dedicated driver.

* ARM: uniphier: support USB boot mode for ProXstream2 / PH1-LD6b SoCMasahiro Yamada2016-02-14-2/+22
| | | | | | | | | | | | | | | | | | The USB boot code is too fat and complicated to be included in SPL (at least for now). So, it was implemented as a separate project (what we call USB-loader). The expected boot sequence is as follows: Boot ROM -> USB-loader -> SPL -> U-Boot proper The USB-loader loads the SPL and U-Boot proper from a USB memory onto the locked L2 cache. Then, SPL needs to copy the U-Boot proper to DRAM, so this mode looks like a NOR boot from the view of SPL. However, we want to distinguish between (genuine) NOR boot and USB boot in some places.

* ARM: uniphier: create early page table at run-timeMasahiro Yamada2016-02-14-38/+94
| | | | | | | | | | | | | | | | | | UniPhier SoCs are not equipped with dedicated on-chip SRAM. Instead, locked outer cache is used as RAM area during the early boot stage where DRAM is not ready yet. This effectively means MMU must be always enabled while we are in SPL. Currently, the SPL image for UniPhier SoCs contains the page table statically defined at compile time. It has been a burden because the 16KB page table occupies a quarter memory footprint of the 64KB SPL image. Finally, there is no more room to implement new features in SPL. Setting aside the NOR boot mode, this issue can be solved by creating the page table onto RAM at run time. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: change stack pointer address for SPLMasahiro Yamada2016-02-14-4/+1
| | | | | | | | | | | | | | | | | No special reason for the current stack address 0x0ff08000. Change it to 0x00100000 to simplify the init_page_table. There are two types of SoCs in terms of the load address of SPL. [1] PH1-sLD3, PH1-LD4, PH1-sLD8 SPL is loaded at 0x00040000-0x0004ffff [2] PH1-Pro4, PH1-Pro5, ProXstream2, PH1-LD6b SPL is loaded at 0x00100000-0x0010ffff The new stack area (0x000f8000-0x00100000) should be safe for all the cases.

* 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.

* 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: 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.
