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>

2016-12-20ARM: zynq: 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 unsafe use of a static variable was causing a specific bug when using the zynq_zybo configuration, U-Boot would generate the following error during image load. This was caused due to dram_init overwriting the relocations for the 'image' variable within the do_bootm function. Out of coincidence the un-initialized memory has a compression type which is the same as the value for the relocation type R_ARM_RELATIVE. Uncompressing Invalid Image ... Unimplemented compression type 23 It should be noted that this is just one way the issue could surface, other cases my not be observed in normal boot flow. Depending on the size of various sections, and location of relocations within __rel_dyn and the compiler/linker the outcome of this bug can differ greatly. This change makes the dram_init* functions use a generic implementation of decoding and populating memory bank and size data.

2016-12-08ARM: zynq: Replace dram_init* functions with board_init_f safe onesNathan Rossi
The dram_init* functions for the zynq board are not safe for use from the board_init_f stage due to its use of the 'tmp' static variable. This incorrect use of a static variable was causing rare issues where the dram_init function would overwrite some parts the __rel_dyn section which caused obscure failures. Using the zynq_zybo configuration, U-Boot would generate the following error during image load. This was caused due to dram_init overwriting the relocations for the "image" variable within the do_bootm function. Out of coincidence the un-initialized memory has a compression type which is the same as the value for the relocation type R_ARM_RELATIVE. Uncompressing Invalid Image ... Unimplemented compression type 23 It should be noted that this is just one way the issue could surface, other cases my not be observed in normal boot flow. This change removes the existing code and copies the implementation of the dram_init and dram_init_banksize from the arch/arm/mach-uniphier/dram_init.c source. This version of these functions does not use static variables and behaves the same (reading banks from fdt, and using the first bank as the ram_size).
