* ARM: uniphier: move SBC and Support Card init code to U-Boot properMasahiro Yamada2017-01-18-27/+19
| | | | | | | | | | | | | | | Initialize SBC and Support Card in U-Boot proper instead of SPL. We may run different firmware (ex. ARM Trusted Firmware) before U-Boot, and basic SoC initialization may be done there. In that case, SPL may not be used. The motivation for preparing SBC and Support Card in SPL was to use LED for early debugging, but this is not mandatory to boot SoCs. With this commit, LED will be unavailable in SPL, but we can use a debug serial instead. So, this change will not be a big deal. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: refactor spl_init_board()Masahiro Yamada2017-01-18-508/+250
| | | | | | | Merge init-*.c into a single file using a table of callbacks because the initialization flow is almost common among SoCs. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: refactor board_init()Masahiro Yamada2017-01-18-95/+141
| | | | | | | The code here is cluttered due to the switch statement. Introduce a table of callbacks to clean up the initialization code across SoCs. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: make BCU init into void functionMasahiro Yamada2017-01-17-10/+10
| | | | | | These functions never fail, so no need to return a value. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: refactor Support Card init codeMasahiro Yamada2017-01-17-28/+8
| | | | | | | | | | | Splitting reset assertion (support_card_reset) and deassertion (support_card_init) is not adding much value any more. Handle all the initialization of Support Card in support_card_init(), then remove support_card_reset(). Also, detect_num_flash_banks() can have a static qualifier.

* ARM: uniphier: refactor SBC init codeMasahiro Yamada2017-01-17-110/+94

* ARM: uniphier: refactor MEMCONF init codeMasahiro Yamada2017-01-17-259/+176
| | | | | | | | | | | | | | Currently, memconf-sld3.c and memconf-pxs2.c duplicate the code. There are 3 patterns in terms of MEMCONF init: - DRAM 2 channels: LD4, sLD8, Pro4, Pro5, LD11 - DRAM 3 channels: sLD3 - DRAM 3 channels (Ch2 is disable by MEMCONF[21]): Pxs2, LD20 All of them can be moved into a single file by a little more refactoring.

* ARM: uniphier: split out UMC clock enableMasahiro Yamada2017-01-17-69/+97
| | | | | | | | The clock enable bits for UMC are more SoC-specific than for the other hardware blocks. Separate the UMC clocks and the other clocks for better code reuse across SoCs. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: remove unneeded argument of uniphier_ld20_pll_init()Masahiro Yamada2017-01-17-11/+3

* | spl: Add a name to the SPL load-image methodsSimon Glass2016-12-09-1/+1
|/ | | | | | | | | | | It is useful to name each method so that we can print out this name when using the method. Currently this happens using a separate function. In preparation for unifying this, add a name to each method. The name is only available if we have libcommon support (i.e can use printf()). Signed-off-by: Simon Glass <sjg@chromium.org>

* ARM: uniphier: refactor DDR PHY parameter dump commandMasahiro Yamada2016-10-29-44/+50

* ARM: uniphier: rework existing DDR PHY code to reuse for LD11 SoCMasahiro Yamada2016-10-29-294/+302
| | | | | | | | | The DDR PHY register view of LD11 is slightly different from that of LD4/Pro4/sLD8, but it will be possible to share the register macros (and I want to re-use as much code as possible). Change the code in the more flexible form. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: do not run harmful code for USB boot mode of LD11 ES3Masahiro Yamada2016-10-29-3/+5
| | | | | | | | | The USB boot without the stand-by MPU is available on ES3 or later of LD11 SoC, but the code in this if-conditional block must not be run when booting from USB. Check if the boot device is USB, and skip the code in the case. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: enable clocks to MIO/STDMAC on LD11 if USB is enabledMasahiro Yamada2016-10-29-0/+13

* ARM: uniphier: insert udelay() just before support_card_reset_deassert()Masahiro Yamada2016-10-10-2/+1
| | | | | | | | | As for LD11/LD20, we can no longer rely on the udelay() in the PLL init functions. udelay(200) is needed here to keep the ethernet device in the reset state for enough time. Anyway, 200 usec is quite short for humans, so nobody cares it. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

* ARM: uniphier: do not setup pins for System Bus on NAND boot modeMasahiro Yamada2016-10-10-2/+6
| | | | | | | | | For LD11 and LD20 SoCs, the System Bus and NAND are multiplexed in the same I/O pins. When booting from a NAND device, pin-mux for the System Bus must not be set-up because they are exclusive with each other. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* spl: Pass spl_image as a parameter to load_image() methodsSimon Glass2016-10-06-4/+5

* spl: Convert boot_device into a structSimon Glass2016-10-06-1/+1
| | | | | | | | | | | At present some spl_xxx_load_image() functions take a parameter and some don't. Of those that do, most take an integer but one takes a string. Convert this parameter into a struct so that we can pass all functions the same thing. This will allow us to use a common function signature.
