2019-06-06spl: at91: add support for SPL_AT91_MCK_BYPASSEugen Hristev
By default the configuration of the PMC is to have an external crystal connected that requires driving on both XIN and XOUT pins. The bypass configuration means that only XIN will be used, the SoC will not do any driving, and the XIN needs to be provided with a proper signal. This is the MOSCXTBY bit in the PMC main clock generator register. The SPL needs to properly initialize the PMC registers before switching to external clock signal and raising the clock to the cruise speed. Also created Kconfig for this specific configuration. By default this is disabled. Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com>

2019-06-05ARM: tegra: Enable position independent build for 64-bitThierry Reding
Note that U-Boot is always chainloaded from cboot starting with L4T release 28. cboot always loads U-Boot to a fixed address, so making the builds position independent isn't strictly necessary. However, position independent builds can be convenient because if U-Boot is ever loaded to an address different from its link address, it will still be able to boot.

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>

2019-06-05ARM: davinci: SPL: fix BSS initializationSekhar Nori
U-Boot README recommends initializing SDRAM in board_init_f(). DA850 was doing it as part of board_init_r() (through call to spl_board_init() which calls arch_cpu_init() which calls da850_ddr_setup()) This worked fine till commit 15b8c7505819 ("davinci: da850evm/omapl138-lcdk: Move BSS to SDRAM because SRAM is full") moved BSS to SDRAM. Functions like mmc_initialize() called in board_init_r() assume BSS is available. Since SDRAM was not initialized when arch/arm/lib/crt0.S tried to initialize BSS to 0, BSS is not initialized correctly. Fix this by simply calling arch_cpu_init() from board_init_f(). Also move preloader_console_init() there to help debug issues with board_init_r(). With this spl_board_init() is no longer needed, we remove it. Tested using MMC/SD boot on OMAP-L138 LCDK board.
