2018-03-23arm64: zynqmp: Correct EG/EV part detection logicSiva Durga Prasad Paladugu
The vcu disable bit in efuse ipdisable register is valid only if PL powered up so, consider PL powerup status for determing EG/EV part. If PL is not powered up, ignore EG/EV part of string. The PL powerup status will be filled by pmufw based on PL PROGB status in the 9th bit of version field.

2018-01-30arm64: zynqmp: Prepare psu_init reworkMichal Simek
Move generic functions to common location psu_spl_init.c. Function declarations are added to private header. These changes are done in connection to the fact that still files from HDF can be copied over and compilation should pass. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2018-01-30xilinx: zynqmp: Use strlen only if env_get doesn't return nullSiva Durga Prasad Paladugu
Add check if boot_targets exists in environment and then generate new_targets env accordingly. Performing strlen on null address causes it to fail with exception if isolation is enabled with DDR address zero as secure. It works with out isolation enabled as zero is valid address but it may lead to junk values in boot_targets. This patch fixes the issue by checking return value of env_get so that it generate boot_targets properly.

2017-12-14arm64: zynqmp: Add support for zynqmp automotive siliconsMichal Simek
Remove silicon prefix. Automotive grade devices are using xazu instead of xczu prefix. The patch "fpga: xilinx: Check for substring in device ID validation" (sha1: f72132673a01216e760864e442f168977cce2bd2) enables this functionality for zynq devices that only substrings are checked. Unfortunately there is no way how to detect device grade that's why this change is reasonable. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2016-12-20ARM64: zynqmp: Replace board specific with generic memory bank decodingNathan Rossi
The dram_init and dram_init_banksize functions were using a board specific implementation for decoding the memory banks from the fdt. This board specific implementation uses a static variable 'tmp' which makes these functions unsafe for execution from within the board_init_f context. This change makes the dram_init* functions use a generic implementation of decoding and populating memory bank and size data.

2016-11-15ARM64: zynqmp: Fix secondary bootmode enablingMichal Simek
Do not setup use_alt bit which copy alternative boot mode to boot mode. The reason is that this bit is cleared after POR but not after any software reset which will cause that after SW reset bootrom will look for different boot image. This patch setups alternative boot mode selection (purely SW handling) and extends code to read this alternative boot mode first and use it if it is setup.

2016-10-19arm: Provide common PSCI based reset handlerAlexander Graf
Most armv8 systems have PSCI support enabled in EL3, either through ARM Trusted Firmware or other firmware. On these systems, we do not need to implement system reset manually, but can instead rely on higher level firmware to deal with it. The exclude list seems excessive right now, but NXP is working on providing an in-tree PSCI implementation, so that all NXP systems can eventually use PSCI as well.

2016-10-18arm: Disable HVC PSCI calls by defaultAlexander Graf
All systems that are running on armv8 are running bare metal with firmware that implements PSCI running in EL3. That means we don't really need to expose the hypercall variants of them. This patch leaves the code in, but makes the code explicit enough to have the compiler optimize it out. With this we don't need to worry about hvc vs smc calling convention when calling psci helper functions. Signed-off-by: Alexander Graf <agraf@suse.de> Reviewed-by: Simon Glass <sjg@chromium.org>

SPL needs to have bigger stack size because of USB. Simple malloc needs to be disabled because dfu code requires different allocation functions. There is no space in OCM that's why random place in DDR is used. BOOTD must be disabled because it is causing compilation error. All variables are disabled and used only variables valid for DFU because they are simple huge. Including automatic variables added by CONFIG_ENV_VARS_UBOOT_CONFIG. Hardcode addresses for u-boot, atf, kernel and dtb just for SPL DFU code. Enable SPL DFU for zcu100. Create new usb_dfu_spl variable just to run Linux kernel loaded in SPL.
