lib: utils: Move fdt fixup helper routines to a different file

2020-03-24T08:00:32Z

FDT helper file contain both fdt fixup and parsing functions. Split the fixup related functions to a separate file for a better code organization. Signed-off-by: Atish Patra Reviewed-by: Anup Patel

platform: fpga/common: Add a fdt parsing helper functions

2020-03-24T07:59:07Z

Different DT based platforms from the sam family may reuse IP blocks with different configurations. These different configurations can be obtained by parsing the device tree. Add a FDT parser framework that can parse various device configurations from device tree. Currently, the parsing algorithms doesn't cover all the use cases or possible combination of DT configurations. It will be improved over time. Signed-off-by: Atish Patra Reviewed-by: Anup Patel

lib: utils: Add a general device tree fix-up helper

2020-03-18T05:34:48Z

This adds a general device tree fix-up helper to do all required device tree fix-ups for a typical platform. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

lib: utils: Add a fdt_cpu_fixup() helper

2020-03-18T05:13:53Z

Add a helper routine to updates the "status" property of a CPU node in the device tree to "disabled" if that hart is in disabled state. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

lib: utils: Move PLIC DT fix up codes to fdt_helper.c

2020-03-18T04:10:14Z

Now that we have a dedicated fdt_helper.c file for DT releated helper routines, move plic_fdt_fixup() codes from plic.c to fdt_helper.c and rename it to fdt_plic_fixup() at the same time, to keep name consistency in the same file. Signed-off-by: Bin Meng Reviewed-by: Atish Patra

lib: utils: Add a fdt_reserved_memory_fixup() helper

2020-03-18T03:49:44Z

Add a helper routine to insert a child node of the reserved memory node in the device tree that describes the protected memory region done by OpenSBI via PMP. Signed-off-by: Bin Meng Reviewed-by: Atish Patra

lib: utils: Support CLINT with 32bit MMIO access on RV64 system

2020-01-02T03:44:36Z

It is possible to have a CLINT implementation which supports only 32bit MMIO accesses on RV64 system so this patch extends our CLINT driver such that platform code can specify whether CLINT supports 64bit MMIO access. Signed-off-by: Anup Patel Reviewed-by: Atish Patra Reviewed-by: Zong Li

utils: Remove tinyfdt.c

2019-06-19T04:25:13Z

tinyfdt.c was originally added to provide a minimal implementation of fdt parsing. However, we have already included libfdt in OpenSBI for more complicated operations. Remove tinfdt and replace its functiolity using libfdt. Signed-off-by: Atish Patra Acked-by: Anup Patel
