2019-06-05ARM: tegra: Import cbootargs value from cboot DTBThierry Reding
Read the boot arguments passed by cboot via the /chosen/bootargs property and store it in the cbootargs environment variable. Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
2019-06-05ARM: tegra: Implement cboot_get_ethaddr()Thierry Reding
This function will attempt to look up an Ethernet address in the DTB that was passed in from cboot. It does so by first trying to locate the default Ethernet device for the board (identified by the "ethernet" alias) and if found, reads the "local-mac-address" property. If the "ethernet" alias does not exist, or if it points to a device tree node that doesn't exist, or if the device tree node that it points to does not have a "local-mac-address" property or if the value is invalid, it will fall back to the legacy mechanism of looking for the MAC address stored in the "nvidia,ethernet-mac" or "nvidia,ether-mac" properties of the "/chosen" node. The MAC address is then written to the default Ethernet device for the board (again identified by the "ethernet" alias) in U-Boot's control DTB. This allows the device driver for that device to read the MAC address from the standard location in device tree.

2019-06-05ARM: tegra: Unify Tegra186 buildsThierry Reding
Tegra186 build are currently dealt with in very special ways, which is because Tegra186 is fundamentally different in many respects. It is no longer necessary to do many of the low-level programming because early boot firmware will already have taken care of it. Unfortunately, separating Tegra186 builds from the rest in this way makes it difficult to share code with prior generations of Tegra. With all of the low-level programming code behind Kconfig guards, the build for Tegra186 can again be unified. As a side-effect, and partial reason for this change, other Tegra SoC generations can now make use of the code that deals with taking over a boot from earlier bootloaders. This used to be nvtboot, but has been replaced by cboot nowadays. Rename the files and functions related to this to avoid confusion. The implemented protocols are unchanged.

2019-06-05ARM: tegra: Workaround UDC boot issues only if necessaryThierry Reding
Resetting the USB device controller on boot is only necessary if the SoC actually has a UDC controller and U-Boot enables support for it. All the Tegra boards support UDC via the ChipIdea UDC driver, so make the UDC on boot workaround depend on the ChipIdea UDC driver. This prevents a crash on Tegra186 which does not have the ChipIdea UDC. Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
2019-06-05ARM: tegra: Support TZ-only access to PMCThierry Reding
Some devices may restrict access to the PMC to TrustZone software only. Non-TZ software can detect this and use SMC calls to the firmware that runs in the TrustZone to perform accesses to PMC registers. Note that this also fixes reset_cpu() and the enterrcm command on Tegra186 where they were previously trying to access the PMC at a wrong physical address.

2019-06-05ARM: tegra: Fix save_boot_params() prototypeThierry Reding
The save_boot_params() function takes as its first four arguments the first four registers. On 32-bit ARM these are r0, r1, r2 and r3, all of which are 32 bits wide. However, on 64-bit ARM thene registers are x0, x1, x2 and x3, all of which are 64 bits wide. In order to allow reusing the save_boot_params() implementation on 64-bit ARM, change it to take unsigned long parameters rather than the fixed size 32-bit integers. This ensures that the correct values are passed. Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>

2019-05-24ARM: socfpga: Clear PL310 early in SPLMarek Vasut
On SoCFPGA A10 systems, it can rarely happen that a reboot from Linux will result in stale data in PL310 L2 cache controller. Even if the L2 cache controller is disabled via the CTRL register CTRL_EN bit, those data can interfere with operation of devices using DMA, like e.g. the DWMMC controller. This can in turn cause e.g. SPL to fail reading data from SD/MMC. The obvious solution here would be to fully reset the L2 cache controller via the reset manager MPUMODRST L2 bit, however this causes bus hang even if executed entirely from L1 I-cache to avoid generating any bus traffic through the L2 cache controller. This patch thus configures and enables the L2 cache controller very early in the SPL boot process, clears the L2 cache and disables the L2 cache controller again. The reason for doing it in SPL is because we need to avoid accessing any of the potentially stale data in the L2 cache, and we are certain any of the stale data will be below the OCRAM address range. To further reduce bus traffic during the L2 cache invalidation, we enable L1 I-cache and run the invalidation code entirely out of the L1 I-cache.
