Configure them to enable non-secure access. For now the only SoC that has this feature is the H3. For other platforms just use a default (weak) empty function so things do not break.

The range-check is not needed at all, since clock_twi_onoff only gets called with such high indexes when CONFIG_I2C3_ENABLE / CONFIG_I2C4_ENABLE is set and Kconfig already only allows these on sun6i / sun7i.

* sunxi: clock: Set AHB1 clock frequency to 200MHz on Allwinner H3Siarhei Siamashka2015-11-221-2/+4
| | | | | | | | | | | | | | | | | | | | | The 3.4 kernel from the Allwinner SDK is clocking AHB1 at 200MHz on Allwinner H3 and using PLL6 as the clock source (PLL6/3). This can be verified by reading the value of the AHB1_APB1_CFG_REG register via /dev/mem. It always reads as 0x3180 regardless of the current cpufreq operating point. So this configuration should be safe for use in U-Boot too. PLL6 also needs to be configured before it is used as the clock source, according to the "CCU / Programming Guidelines" section of the Allwinner manual. The current low AHB1 clock speed is limiting the USB transfer speed when booting via FEL. This patch can increase the FEL USB transfer speed from ~510 KB/s to ~950 KB/s.

| | | | | | | | | | | | | | | | | | | | | | | Make spl_*_load_image() functions return a value instead of hanging if a problem is encountered. This enables main spl code to make the decision whether to hang or not, thus preparing it to support alternative boot devices. Some boot devices (namely nand and spi) do not hang on error. Instead, they return normally and SPL proceeds to boot the contents of the load address. This is considered a bug and is rectified by hanging on error for these devices as well.

* sunxi: retrieve FEL-provided values to environment variablesBernhard Nortmann2015-09-291-1/+2
| | | | | | | | | | | | | | | | | | | This patch extends the misc_init_r() function on sunxi boards to test for the presence of a suitable "sunxi" SPL header. If found, and the loader ("fel" utility) provided a non-zero value for the boot.scr address, then the corresponding environment variable fel_scriptaddr gets set. misc_init_r() also sets (or clears) the "fel_booted" variable depending on the active boot device, using the same logic as spl_boot_device(). The goal is to provide sufficient information (within the U-Boot environment) to make intelligent decisions on how to continue the boot process, allowing specific customizations for the "FEL boot" case.

* sunxi: usb-phy: Never power off the usb portsHans de Goede2015-08-081-0/+7
| | | | | | | | | | | | | | | | | | | | | USB devices are not really designed to get the power bounced off and on at them. Esp. USB powered harddisks do not like this. Currently we power off the USB ports both on a "usb reset" and when booting the kernel, causing the usb-power to bounce off and then back on again. This patch removes the powering off calls, fixing the undesirable power bouncing. Note this requires some special handling for the OTG port: 1) We must skip the external vbus check if we've already enabled our own vbus to avoid false positives 2) If on an usb reset we no longer detect that the id-pin is grounded, turn off vbus as that means an external vbus may be present now Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

* sunxi: Remove support for building "old-fashioned" fel binariesHans de Goede2015-05-291-8/+0
| | | | | | | | | | The latest versions of the fel tool support loading normal u-boot builds directly, and this is now the preferred way to use the fel boot method. This commit removes support for the old deprecated standalone fel builds. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
* sunxi: Use axp221 sid on a33Hans de Goede2015-05-291-5/+3
| | | | | | | | | Unlike the A31 and the A23 the A33 actually has a SID inside the SoC again, but sid[3] is 0 (at least on some SoCs), so it is better to use the axp221 sid. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
