* ARM: uniphier: drop UniPhier specific SMP codeMasahiro Yamada2015-11-11-61/+0
| | | | | | | | | | | The latest Linux can directly handle SMP operations for UniPhier SoCs without any help of U-boot. Drop the relevant code from U-boot. See commit b1e4006aeda8c8784029de17d47987c21ea75f6d ("ARM: uniphier: rework SMP operations to use trampoline code") in Linux Kernel.

* 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.

* ARM: uniphier: delete unneeded input enable for low-level debugMasahiro Yamada2015-09-25-5/+0

* 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.

| | | | | | | | | | | | The L2 cache is used as a temporary SRAM on SPL. Now the secondary CPUs store the necessary code for jumping to Linux on their L1 I-caches. So, the L2 cache can be disabled much earlier, at the very entry of U-Boot proper (lowlevel_init). This makes the boot sequence clearer. Also, as the L1 cache has been disabled by the start.S, enable_caches() does not need to do it again. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Thus, the way size is 32KB/64KB for old/new SoCs. To keep lowlevel_init SoC-independent, set BOOT_RAM_SIZE to the constant value 32KB.
