We found that we may want to load some components of BL31 on the RK3399 into SRAM.

2016-08-11rockchip/rk3399: Add code to neuter Type-C PHY for firmware USBJulius Werner
The Rockchip RK3399 integrates a USB Type-C PHY in charge of things like SuperSpeed line muxing for rotated cable orientations in the SoC. While fancy, this is very complicated and we don't want to implement support for the whole thing in firmware. The USB Type-C standard has intentionally been designed in a way that the USB 2.0 (HighSpeed) lines always "just work" in any orientation (by just shorting different pins in the connector together) so that simple use cases like ours can get basic USB functionality without much hassle. However, a semi-configured Type-C PHY can confuse USB 3.0 capable devices into thinking we're actually supporting SuperSpeed, and fail at that rather than establishing a reliable HighSpeed connection. This patch sets enough bits in the Type-C PHY to electrically isolate the SuperSpeed lines from the connector so that the connected device isn't going to get any fancy ideas and reliably falls back to USB 2.0. Also clean up the rest of the USB code while we're at it: avoid writing a few bits that are already in the right state from their reset values anyway, or reading values whose content we already know for this SoC. Rename the USB controllers to the name actually used in the Rockchip documentation (USB OTGx) rather than the name blindly copied from Exynos code (USB DRDx).

Coming Kevin revisions will switch back to an I2C TPM. This patch adds the required configuration options and code to support that.

2016-06-12Kconfig: Set VBOOT_OPROM_MATTERS for relevant non-x86 devicesJulius Werner
The VBOOT_OPROM_MATTERS configuration option signals to vboot that the board can skip display initialization in the normal boot path. It's name is a left-over from a time when this could only happen by avoiding loading the VGA option ROM on x86 devices. Now we have other boards that can skip their native display initialization paths too, and the effect to vboot is the same. (Really, we should rename oprom_matters and oprom_loaded to display_skippable and display_initialized or something, but I don't think that's worth the amount of repositories this would need to touch.) The only effect this still has in today's vboot is to reboot and explicitly request display initialization for EC software sync on VBOOT_EC_SLOW_UPDATE devices (which we haven't had yet on ARM). Still, the vboot flag just declares the capability (for skipping display init), and it should be set correctly regardless of whether that actually makes a difference on a given platform (right now). This patch updates all boards/SoCs that have a conditional path based on display_init_required() accordingly.

2016-05-09rockchip/rk3399: Set all 4 DVFS voltage rails to 1.1V @300kHzVadim Bendebury
Previous code had several problems: * It was only initting 3 of the 4 voltage rails hooked up to PWM regulators. * It was using a PWM frequency that was out of range. Apparently from testing 300kHz is best. * It was initting all rails to .9V. On my Kevin I needed 1.1V to make booting all 6 cores / rebooting reliable. With this fix both booting all 6 cores in the kernel is reliable (if we tell the kernel not to touch the PWM) and the "reboot" command from Linux userspace is also reliable (previously it crashed in coreboot). NOTES: * Setting all rails to the same voltage doesn't make a lot of sense. We should figure out what these should _actually_ be. Presumably the little CPU rail can be lower, at least. ...and we don't use the GPU in the BIOS so we should set that lower.

As the diagram below, the aclk_perihp always be the parent of more higher speed peripheral devices like pcie, and hclk_perilp1 for spi, i2c, aclk_perilp0 for crypto.
