* ARM: UniPhier: add pin mux setting for NAND CS1 of PH1-Pro4Masahiro Yamada2015-05-31-0/+2
| | | | | | | The chip select 1 of the NAND controller is available if you want to use, although the pins are shared with UART port 2. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: UniPhier: replace <asm/io.h> with <linux/io.h>Masahiro Yamada2015-05-31-32/+24
| | | | | | | In the Linux coding style, it is recommended to include <linux/io.h> rather than <asm/io.h>. Follow this trend. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: UniPhier: move UART pin settings to SPLMasahiro Yamada2015-03-24-14/+30
| | | | | | | | The UniPhier platform is going to enable Driver Model and UART support on SPL. Move UART pin settings to early_pin_init(), which is called from SPL. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: UniPhier: move platform devices to SPLMasahiro Yamada2015-03-24-1/+1
| | | | | | | | | | Since we do not have OF_CONTROL support for SPL, platform devices are necessary to enable Driver Model on SPL. To prepare for that, move platdevice.o to SPL and enable it by CONFIG_SPL_DM. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: UniPhier: remove stop_mpll() from PH1-Pro4 PLL initializationMasahiro Yamada2015-03-01-17/+0
| | | | | | | | | | This function was intended for MN2WS0235 (what we call PH1-Pro4TV). On that SoC, MPLL is already running on the power-on reset and it makes sense to stop the PLL at early boot-up. On the other hand, PH1-Pro4(R) does not have SC_MPLLOSCCTL register, so this function has no point. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* ARM: UniPhier: consolidate MEMCONF setting codeMasahiro Yamada2015-03-01-10/+1
| | | | | | | | | | This code is duplicated in ph1-ld4/sg_init.c and ph1-pro4/sg_init.c. Merge the same code into a new file, memconf.c. The helper functions no longer have to be placed in the header file. Also, move them into memconf.c. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* ARM: UniPhier: support 1CS support card for all the UniPhier SoCsMasahiro Yamada2015-03-01-33/+46
| | | | | | | | | | | Two support card variants are used with UniPhier reference boards: - 1 chip select support card (original CPLD) - 3 chip selects support card (ARIMA-compatible CPLD) Currently, the former is only supported on PH1-Pro4, but it can be expanded to PH1-LD4, PH1-sLD8 with a little code change.

* ARM: UniPhier: enable xHCI and GIO cores for PH1-Pro4Masahiro Yamada2015-03-01-0/+15
| | | | | | This is necessary to use the USB 3.0 host controllers on PH1-Pro4. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* ARM: UniPhier: add I/O pin settings for xHCI on PH1-Pro4Masahiro Yamada2015-03-01-0/+7
| | | | | | This is necessary to use the xHCI cores for PH1-Pro4. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* ARM: UniPhier: remove EHCI platform devicesMasahiro Yamada2015-03-01-10/+1
| | | | | | | | | | | Now UniPhier platform highly depends on Device Tree configuration (CONFIG_OF_CONTROL is select'ed by Kconfig). Since the EHCI is only used on main U-Boot, we can drop platform devices of the EHCI controllers. We still keep UART platform devices because they might be useful for SPL.

* ARM: UniPhier: enable STDMAC for EHCIMasahiro Yamada2015-03-01-1/+4
| | | | | | | Deassert the reset signal and provide the clock for STDMAC core. This is necessary for the USB 2.0 host controllers. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* ARM: UniPhier: reset NAND core in SPL for non-NAND boot modeMasahiro Yamada2015-03-01-0/+5
| | | | | | | | | | | | | | | | | | | | | | For all the UniPhier SoCs so far, the reset signal of the NAND core is automatically deasserted after the PLL gets stabled. (The bit 2 of SC_RSTCTRL is default to one.) This causes a fatal problem on the NAND controller of PH1-LD4. For that SoC, the NAND I/O pins are not set up yet at the power-on reset except the NAND boot mode. As a result, the NAND controller begins automatic device scanning with wrong I/O pins and finally hangs up. Actually, U-Boot dies after printing "NAND:" on the console unless the boot mode latch detected the NAND boot mode. To work around this problem, reset the NAND core in SPL for non-NAND boot modes. If CONFIG_NAND_DENALI is enabled, the reset signal is deasserted again in U-Boot proper. At this time, I/O pins have been correctly set up, the device scanning should succeed.

* ARM: UniPhier: split clkrst_init() into two functionsMasahiro Yamada2015-03-01-8/+44
| | | | | | | | | | | | | | Split the current clkrst_init() into two functions: - early_clkrst_init(): called from SPL Deassert the reset signals of the memory controller and some other basic cores. - clkrst_init(): called from main U-boot Deassert the reset signals that are necessary for the access to peripherals etc. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* ARM: UniPhier: rename SC_CLKCTRL_CLK_* to SC_SCLKCTRL_CEN_*Masahiro Yamada2015-03-01-3/+3
| | | | | | Follow the register macros in the LSI specification book. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* ARM: UniPhier: fix SBC init codeMasahiro Yamada2015-03-01-5/+5
| | | | | | | | | Now UniPhier SoCs only work with CONFIG_SPL and the function sbc_init() is called from SPL. The conditional #if !defined(CONFIG_SPL_BUILD) has no point any more. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

* ARM: UniPhier: include <mach/*.h> instead of <asm/arch/*.h>Masahiro Yamada2015-03-01-18/+18
| | | | | | | | | Since commit 0e7368c6c426 (kbuild: prepare for moving headers into mach-*/include/mach), we can replace #include <asm/arch/*.h> with <mach/*.h> so we do not need to create the symbolic link during the build. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
