scripts: use env to invoke bash

2022-12-10T16:30:27Z

Not all systems have bash at a fixed location like /bin/bash. FreeBSD, for example, would typically have it at /usr/local/bin/bash. When building OpenSBI on freebsd system, the build breaks. Its advisable to use: #!/usr/bin/env bash Signed-off-by: Himanshu Chauhan Reviewed-by: Xiang W Reviewed-by: Anup Patel

scripts/create-binary-archive.sh: remove andes/ae350 build directory

2022-12-05T12:03:03Z

The andes-specific files have been moved to generic platform so we can drop this line. Signed-off-by: Yu Chien Peter Lin Reviewed-by: Bin Meng Reviewed-by: Anup Patel

Makefile: Compile lib/utils sources separately for each platform

2022-08-08T04:03:14Z

Currently, if same build directory is used to compile two different platforms then lib/utils objects are shared for these platforms. We will be having platform specific configs to enable/disable drivers in lib/utils and select compile time options for lib/utils sources. This means lib/utils sources will now be compiled in a platform specific way. To tackle above, we update top-level Makefile as follows: 1) Don't create libsbiutils.a anymore because this can't be shared between platforms. 2) Compile lib/utils sources separately for each platform. 3) Add comments showing which make rules are for lib/sbi, lib/utils, firmware, and platform sources.

scripts: Add Kconfiglib v14.1.0 under scripts directory

2022-08-08T04:03:03Z

We adopt Kconfiglib v14.1.0 sources under scripts directory so that top-level OpenSBI makefile can directly use Kconfiglib scripts without expecting users to install a particular version of Kconfiglib on their build system.

Makefile: Add support for generating C array at compile time

2022-05-13T03:56:00Z

Generating C array at compile time based on details provided by objects.mk is a very useful feature which will help us compile only a subset of drivers or modules. We add a bash script (carray.sh) which takes array details and object/variable list from command-line to generate a C source containing array of object/variable pointers. We also extend top-level makefile to use carray.sh whenever specified through objects.mk. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

platform: Remove sifive/fu540 platform

Now that SiFive HiFive Unleashed board is using the generic platform support in OpenSBI, let's remove the old non-generic one. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

platform: Remove platform/thead

We could use platform/generic instead, and won't use platform/thead/c910 again. Signed-off-by: Guo Ren Reviewed-by: Anup Patel

Makefile: Allow padding zeros when converting DTB to C source

2020-10-18T05:03:57Z

We extend d2c.sh to allow padding zeros in output C source when converting DTB to C source. Using this feature, platforms can create extra room for in-place FDT fixups on built-in DTBs. Signed-off-by: Heinrich Schuchardt Signed-off-by: Anup Patel Reviewed-by: Atish Patra

Makefile: Add mechanism for platforms to have multiple builtin DTBs

2020-06-05T03:32:59Z

Currently, we can only include one DTB as builtin for a platform using FDT_PAYLOAD_DTB make variable in platform config.mk. This patch adds new mechanism using which we can convert any DTS file to C source and futher compile-n-link it with libplatsbi.a. The generated C source will have the DTB contents as an array "const char _start[]" where is specified in platform objects.mk makefile. Example1 -------- If we have built-in k210.dts and desired is "dt_k210" then specify following in platform objects.mk: platform-objs-y += k210.o platform-varprefix-k210.o = dt_k210 Example2 -------- If we have built-in abc/k210.dts and desired is "dt_abc_k210" then specify following in platform objects.mk: platform-objs-y += abc/k210.o platform-varprefix-abc-k210.o = dt_abc_k210 Signed-off-by: Anup Patel Reviewed-by: Atish Patra

platform: Remove spike directory

2020-05-04T04:39:51Z

The OpenSBI generic platform works perfectly fine on the QEMU spike machine and Spike emulator so let's remove dedicated Spike platform from OpenSBI. All Spike platform related documentation in OpenSBI will now suggest using OpenSBI generic platform. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Alistair Francis
