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

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
