Makefile: Add option to use toolchain default ABI and ISA string

2020-11-02T03:51:50Z

When PLATFORM_RISCV_ABI and PLATFORM_RISCV_ISA are not specified, we force "-mabi=lp64 -march=rv64gc" for RV64 and force "-mabi=ilp32 -march=rv32gc" for RV32. This can prevent users from using the toolchain default "-mabi" and "-march" options. To allow using toolchain defaults, we add compile-time option PLATFORM_RISCV_TOOLCHAIN_DEFAULT which when enabled forces the top-level makefile to use toolchain default ABI and ISA string. To enable the option, pass "PLATFORM_RISCV_TOOLCHAIN_DEFAULT=1" to top-level make. Reported-by: Alistair Francis Signed-off-by: Anup Patel Reviewed-by: Alistair Francis

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: Build ELF, BIN and LD script in platform build directory

2020-10-18T04:44:17Z

Currently, the make rules for ELF, BIN and LD script are little generic to allowing ELF, BIN and LD script to be anywhere in the build directory. For OpenSBI firmwares, the ELF, BIN, and LD script are always platform specific so we update make rules accordingly. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

firmware: Remove FW_PAYLOAD_FDT and related documentation

2020-06-05T03:33:05Z

Now that no platform is using FW_PAYLOAD_FDT mechanism, we remove related code from Makefile and related documentation. 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

Makefile: Preprocess builtin DTS

2020-06-05T03:32:55Z

In order to use GCC style defines and macros in DTS, we should preporcess builtin DTS before converting it to DTB. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

Makefile: Fix builtin DTB compilation for out-of-tree platforms

The make rule for builtin DTB compilation does not consider out-of-tree platforms so this patch fixes it. Signed-off-by: Anup Patel Reviewed-by: Atish Patra
