* 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
| | | | | | | | At the moment, the clk driver is not clever enough to automatically enable parent clocks like Linux. Enable the STDMAC clock explicitly if USB is enabled. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: fix DRAM init poll address for LD4, Pro4, sLD8Masahiro Yamada2016-10-29-3/+3

* ARM: uniphier: rename ddrphy-ld20-regs.h to ddruqphy-regs.hMasahiro Yamada2016-10-29-4/+4
| | | | | | | This PHY might be used for other SoCs in the future. Avoid including the SoC name in the header name. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

* ARM: uniphier: adjust fdt_file environment handling to latest LinuxMasahiro Yamada2016-10-29-12/+9
| | | | | | | The environment fdt_file is useful to remember the appropriate DTB file name. Adjust it to the recent renaming in the upstream kernel. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: remove unnecessary EHCI reset deassertionMasahiro Yamada2016-10-18-8/+6

* libfdt: Bring in upstream stringlist functionsSimon Glass2016-10-13-3/+2
| | | | | | | | | | | | | | These have now landed upstream. The naming is different and in one case the function signature has changed. Update the code to match. This applies the following upstream commits by Thierry Reding <treding@nvidia.com> : 604e61e fdt: Add functions to retrieve strings 8702bd1 fdt: Add a function to get the index of a string 2218387 fdt: Add a function to count strings Signed-off-by: Simon Glass <sjg@chromium.org>
* 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: add work-around for VBO noise problemMasahiro Yamada2016-10-10-0/+7
| | | | | | | Raise the VDD09 voltage line to 1.0V to suppress VBO noise. This errata work-around code is needed only for ES1. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: update DRAM init code for LD20 SoC (2nd)Masahiro Yamada2016-10-10-333/+356
| | | | | | | | | | | - Do not reference CONFIG_DDR_FREQ; now the DDR frequency is passed from the uniphier_board_data structure - Constify parameter arrays - Tidy up cluttered macros - Lots of code cleanups - Lots of coding style fixes Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: enable SSC for DPLL (DRAM PLL) on LD11 SoCMasahiro Yamada2016-10-10-0/+1

* 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
| | | | | | | | | Rather than having a global variable, pass the spl_image as a parameter. This avoids BSS use, and makes it clearer what the function is actually doing. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
* spl: Convert spl_board_load_image() to use linker listSimon Glass2016-10-06-1/+2

* 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.

* ARM: uniphier: add PLL init code for LD11 SoCMasahiro Yamada2016-09-23-7/+71
| | | | | | | | | | - Initialize PLLs (SPL initializes only DPLL to save the precious SPL memory footprint) - Adjust CPLL/MPLL to the final tape-out frequency - Set the Cortex-A53 clock to the maximum frequency since it is running at 500MHz (SPLL/4) on startup Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: move CONFIG_SPL_* to defconfig or selectMasahiro Yamada2016-09-23-15/+0
| | | | | | | | | | | | As I repeated in the ML, I am unhappy with config entries with bare defaults. Kick them out of arch/arm/mach-uniphier/Kconfig. Currently, CONFIG_SPL_SERIAL_SUPPORT is not user-configurable (build fails without it), but it should be fixed later anyway, so I am moving CONFIG_SPL_SERIAL_SUPPORT to defconfigs.

| * ARM: uniphier: merge board init functions into board_init()Masahiro Yamada2016-09-14-40/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the UniPhier platform calls several init functions in the following order: [1] spl_board_init() [2] board_early_init_f() [3] board_init() [4] board_early_init_r() [5] board_late_init() The serial console is not ready at the point of [2], so we want to avoid using [2] from the view point of debuggability. Fortunately, all of the initialization in [2] can be delayed until [3]. I see no good reason to split into [3] and [4]. So, merge [2] through [4].

| * ARM: uniphier: display revision of Micro Support Card 3.6.x kindlyMasahiro Yamada2016-08-28-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The revision of the original support card (rev 3.5, rev 3.6) fits in the 8 bit width revision register. When it was extended in a weird way, it was versioned in the format of "3.6.x" (where it should have been "3.7", of course). What is worse, only the sub-level version "6.x" was recorded in the 8 bit width register, completely ignoring the compatibility of the revision register format. This patch saves madly-versioned support cards by assuming the major version "3" when the MSB 4 bit of the register is read as "6". With this, the support card revision that were displayed as "6.10" is now corrected to "3.6.10". Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

(it is supported since PSCI 0.2, but there is no CONFIG to enable it in U-Boot for now.) Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
