* arm64: xilinx: Never touch DDR if system has no DDRMichal Simek2020-04-061-1/+5
| | | | | | | If DDR is not mapped do not touch it. Default XILINX_OF_BOARD_DTB_ADDR is pointing to DDR. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* arm64: zynqmp: Reorder parameters for zynqmp_mmio_write()Michal Simek2020-04-061-1/+1
| | | | | | | Parameter order is not correct based on zynqmp_mmio_write() declaration. Fixes: be52372ff1bb ("arm64: zynqmp: Use zynqmp_mmio_read/write functions") Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* arm64: zynqmp: Move timeout for clock propagation below psu_initMichal Simek2020-04-061-0/+3
| | | | | | | | Delay required for clock propagation is tighly coupled with initialization done in psu_init(). That's why call it also for u-boot proper with CONFIG_ZYNQMP_PSU_INIT_ENABLED enabled. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* arm64: zynqmp: Add support for debug uart also for U-Boot properMichal Simek2020-04-061-3/+12
| | | | | | | | | board_early_init_f() is the right location where debug uart can be configurated (after MIO initialization). The patch is taking this call from SPL to also make it available for U-Boot proper. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

* arm64: zynqmp Add support for zcu102 rev1.1Michal Simek2020-04-061-0/+1042
| | | | | | | rev1.1 has different DDR sodimm module that's why it requires different DDR configuration. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* arm64: zynqmp: Check firmware node when driver is enabledMichal Simek2020-04-061-0/+2
| | | | | | | ZynqMP mini configurations works without PMU firmware that's why there is no reason to enable the driver and check if it was probed properly. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* arm64: zynqmp: Print multiboot register value in EL3Michal Simek2020-04-061-0/+14

* arm: xilinx: Fill DEVICE_TREE directly in MakefilesMichal Simek2020-02-282-0/+10
| | | | | | | | DEVICE_TREE variable is not exported from dts/Makefile that's why it is necessary to setup directly before use. Fixes: 312f2c5b14fa ("arm: xilinx: Use device tree which can be passed on cmd line") Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* arm: zynq: zybo z7: fix MIO init issueMilan Obuch2020-02-281-2/+2
| | | | | | | | | | | | | | | | The board has two push button connected to MIO pins 50 and 51, which have a pull-down resistor and are connected to 1.8V when pressed. These two pins are wrongly initialized with internal pull-up enabled so they are reported as 1 all the time with no change when pressed. Disable the internal pull-up to fix the issue.

* dm: core: Rename ofnode_get_chosen_prop()Simon Glass2020-02-051-1/+1
| | | | | | | | | | | | | This function is actually intended to read a string rather than a property. All of its current callers use it that way. Also there is no way to return the length of the property from this function. Rename it to better indicate its purpose, using ofnode_read as the prefix since this matches most other functions. Also add some tests which are missing for these functions. Signed-off-by: Simon Glass <sjg@chromium.org>
* common: Move reset_cpu() to the CPU headerSimon Glass2020-01-171-0/+1

* arm: xilinx: Use device tree which can be passed on cmd lineMichal Simek2020-01-142-2/+2
| | | | | | | | | DEVICE_TREE variable has been added by commit 6ab6b2afa091 ("dts: re-write dts/Makefile more simply with Kbuild") where DT can be specified on command line. If it is not then CONFIG_DEFAULT_DEVICE_TREE is used to ensure backward compatibility. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* arm64: zynqmp: Fix symlinks to SC psu_init* filesMichal Simek2020-01-145-0/+2

* arm: zynq: Remove low level UART settingMichal Simek2020-01-1414-1018/+0

* arm64: zynqmp: Remove low level UART settingMichal Simek2020-01-1415-104/+0

* arm64: zynqmp: Do not assing MIO34 that early on zcu100Michal Simek2020-01-141-1/+6
| | | | | | | | | | | | MIO34 is connected to POWER_KILL signal. When MIO configuration is done in psu_init() and this pin is assigned to PMU but PMU configuration is not loaded yet. PMU gpio output is high that means board is powered off immediately. The patch is fixing this sequence that MIO34 stays assing to ps gpio IP. PMU config is loaded in SPL and then pin assigned to PMU through psu_post_config_data(). Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* arm64: zynqmp: Add support for OF_SEPARATE with board DTBMichal Simek2020-01-142-7/+24
| | | | | | | | | | | | | OF_BOARD and OF_SEPARATE can use board specific board_fdt_blob_setup(). OF_BOARD option is mostly used for picking up DTB from certain location. OF_SEPARATE option is used when DTB is appended after u-boot binary. This board specific function is aligned with current version in lib/fdtdec.c with checking CONFIG_XILINX_OF_BOARD_DTB_ADDR address first. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* arm64: zynqmp: Rename fw_dtb variable to fdt_blobMichal Simek2020-01-141-4/+4
| | | | | | | The reason for this change is just get in sync with board_fdt_blob_setup() available at lib/fdtdec.c. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* board: xilinx: Add support for user configurable boot script offsetT Karthik Reddy2020-01-144-0/+15
| | | | | | | | | | | | | | | Currently "script_offset_f" env variable is hardcoded, this variable specifies from which offset of the flash boot.scr should be read/write. As flashes are of different sizes having a fixed offset makes it difficult to load other images into the flash which may overwrite the boot script or cannot utilize the full memory. This current fix creates a new config "CONFIG_BOOT_SCRIPT_OFFSET" which holds the offset address, overwrites the "script_offset_f" variable. Also removed existing variable with default values, as the default values are held by CONFIG_BOOT_SCRIPT_OFFSET Signed-off-by: T Karthik Reddy <t.karthik.reddy@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* arm64: zynqmp: Fix emmc boot mode boot_target sequenceT Karthik Reddy2020-01-141-2/+11
| | | | | | | | | | | Emmc boot devcie is mounted to mmc@ff160000 controller on zynqmp. Detect mmc alias at run time for setting up proper boot_targets sequence instead of setting boot_targets manually. Removed setting "modeboot" variable as it not longer need as we switched to distro boot.

* arm64: versal: Fix emmc boot mode boot_target issueT Karthik Reddy2020-01-141-1/+8
| | | | | | | | | | | Emmc boot devcie is mounted to sdhci@f1050000 controller on versal, while in emmc boot mode, boot tragets are set to mmc0. So removed mmc0 and using the dev seq number from the sdhci@f1050000 controller. Dev seq number is setup based on DT aliases that's why needs to be setup at run time.

| | | | | | | | | | | | These functions belong in cpu_func.h. Another option would be cache.h but that code uses driver model and we have not moved these cache functions to use driver model.

Need to use atmel fallback. - Fix si570 I2C slave address and add corresponding part numbers. - Enable AMS for system monitoring. - phy reset property should be commented because it will throw a warning dump when called from context that can sleep.
