2019-06-05ARM: tegra: Restore DRAM bank countThierry Reding
Commit 86cf1c82850f ("configs: Migrate CONFIG_NR_DRAM_BANKS") reduced the number of DRAM banks supported by U-Boot from 1026 to 8 on P2771-000 boards. However, as explained in commit a9819b9e33bd ("ARM: tegra: p2771-000: increase max DRAM bank count"), the platform can have a large number of unusable chunks of memory (up to 1024), so a total of 1026 DRAM banks are needed to describe the worst-case situation. In practice the number of DRAM banks needed will typically be much lower, but we should be prepared to properly deal with the worst case.

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>

This function can be used to set the local MAC address for the default Ethernet interface in its device tree node. The default interface is identified by the "ethernet" alias. One case where this is useful is for devices that store their MAC address in a custom location.

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.

2019-06-05ARM: davinci: omal138_lcdk: fix MMC boot breakage due to driver model conversionSekhar Nori
commit 21af33ed0319 ("ARM: davinci: omapl138_lcdk: Enable DM_MMC") wanted to enable DM_MMC only for U-Boot and not for SPL. But CONFIG_DM_MMC is defined for SPL build too. Because of this MMC device was not getting registered for SPL causing MMC/SD boot breakage. Instead use CONFIG_IS_ENABLED(DM_MMC) which will remain false until CONFIG_SPL_DM_MMC is defined.
