2016-02-29sniper: Various minor cleanups, missing Kconfig configs and reorganisationPaul Kocialkowski
This introduces some minor cleanups, regarding aspects such as board name, code and headers organization as well as deprecated and missing config options. Signed-off-by: Paul Kocialkowski <contact@paulk.fr> Reviewed-by: Tom Rini <trini@konsulko.com>

2016-03-01ARM: uniphier: fix warnings reported by aarch64 compilerMasahiro Yamada
The UniPhier SoC family has not supported ARMv8 yet, but these would cause warnings if they were compiled with a 64bit compiler. Before adding the ARMv8 support really, fix them now. Because UniPhier SoCs do not support Large Physical Address Extension, casting "phys_addr_t" into "unsigned long" would carry the address as is.

2016-03-01ARM: uniphier: prepare directory structure for ARMv8 SoC supportMasahiro Yamada
Before adding ARMv8 support, this commit refactors the directory structure. Move ARMv7 specific files to arch/arm/mach-uniphier/arm32 to avoid a mess by mixture of ARMv7 and ARMv8 code. Also move the "select CPU_V7" to the lower-level menu because we will have to select ARM64 instead of CPU_V7 for ARMv8 SoCs. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-02-29ARM: uniphier: rename PH1-LD10/PH1-sLD11 to PH1-LD20/PH1-LD11Masahiro Yamada
Due to the company's awful projecting, PH1-LD10 and PH1-sLD11 have been renamed to PH1-LD20 and PH1-LD11, respectively. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-02-29ARM: uniphier: rework UniPhier SoC select in KconfigMasahiro Yamada
The chains of "depends on <SoC_name>" in the current Kconfig is clumsy. The idea here is to allow users to choose a SoC group first (SoC group consists of some SoCs that can coexist in one binary). Then, allow to enable/disable each SoC support in the selected SoC group. This makes the Kconfig menu clearer. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-02-29ARM: uniphier: rename variable for DRAM controller base addressMasahiro Yamada
Rename the variable that contains the base address for consistency. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-02-29ARM: uniphier: remove unused macros for UMC base addressesMasahiro Yamada
These macros are no longer used. These base addresses are SoC-dependent, so they should not be placed in the header. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-02-29ARM: uniphier: rework DRAM size handling in UMC init codeMasahiro Yamada
Currently, DRAM size is converted twice: size in byte -> size in Gbit -> enum Optimize the code by converting the "size in byte" into enum directly. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-02-29ARM: uniphier: optimize PH1-Pro4 UMC init code with "for" loopMasahiro Yamada
Now this code can be re-written with a "for" statement instead of calling the same function multiple times. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-02-29ARM: uniphier: optimize PH1-LD4 UMC init code with "for" loopMasahiro Yamada

2016-02-29ARM: uniphier: refactor DDR-PHY init codeMasahiro Yamada
The if-else statements for the frequency-dependent register settings seem clumsy. Moving them to arrays would make it cleaner. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-02-29ARM: uniphier: remove unused argument of ph1_ld4_ddrphy_init()Masahiro Yamada
The DDR PHY settings no longer depend on the DRAM size. Drop the argument from the init function. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-02-29ARM: uniphier: merge DDR PHY init code for 3 SoCsMasahiro Yamada
Now these three are almost the same. The only difference is the DTPR1 register dependency on the DRAM size, but it can be ignored. (It has already been ignored in PH1-sLD8 and PH1-Pro4.) Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-02-29ARM: uniphier: add a field to specify DDR3+Masahiro Yamada
Add a field to distinguish DDR3+ from (standard) DDR3. It also allows to delete CONFIG_DDR_STANDARD (this is not a software configuration, but a board attribute). Default DDR3 spec for each SoC: PH1-LD4, PH1-sLD8: DDR3+ Others: DDR3 Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-02-29ARM: uniphier: disable debug circuit clocks for PH1-Pro4Masahiro Yamada
These settings control the clocks around the memory controller. The debug ability is unneeded once it works properly. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-02-29ARM: uniphier: remove UMC_INITCTL* and UMC_DRMR* settingsMasahiro Yamada
These settings were used only for the PH1-sLD3 and older SoCs. The PH1-LD4 and newer one just ignore them because their DDR-PHY take care of such timing parameters instead. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-02-29ARM: uniphier: refactor UMC init code for ProXstream2Masahiro Yamada
Currently, a dummy value is defined for the UMC_SPCCTLA register when the DRAM size is zero. This seems weird because the controller does not need setting in the first place if the size is zero. Also, redefine enum dram_size to represent the DRAM size per 16-bit unit. This makes things simpler because the channel 0 and 1 are connected with 32-bit width DRAM, while the channel 2 is connected with 16-bit width one. I am renaming SIZE_* into DRAM_SZ_* (and also FREQ_* to DRAM_FREQ_* for consistency) while I am here because SIZE_* might be easily mixed-up with the macros in include/linux/sizes.h.

2016-02-29ARM: uniphier: default to environment in eMMCMasahiro Yamada
Of the several boot devices supported, it looks like the eMMC is the most commonly used. Enable CONFIG_ENV_IS_IN_MMC by default. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-02-29ARM: uniphier: add a command to find the first MMC (non-SD) deviceMasahiro Yamada
UniPhier SoC family supports both (e)MMC boot and SD card boot; however, both of them are handled in the same uclass. When booting from the eMMC, we want to know the device number of the (e)MMC, not SD. This command is useful to find the first MMC (non-SD) device.

2016-02-29ARM: uniphier: add eMMC boot supportMasahiro Yamada
