This patch introduces following optional PLATFORM options: PLATFORM_RISCV_XLEN -> RISC-V register width PLATFORM_RISCV_ABI -> RISC-V GCC ABI PLATFORM_RISCV_ISA -> RISC-V GCC ISA string PLATFORM_RISCV_CODE_MODEL -> RISC-V GCC Code Model If the above options are not provided by platform config.mk or by command-line parameters then: 1. PLATFORM_RISCV_XLEN will be determined using toolchain capability 2. PLATFORM_RISCV_ABI, PLATFORM_RISCV_ISA, and PLATFORM_RISCV_CODE_MODEL is set to value best suited for generic libsbi.a As a result of these optional PLATFORM options, the platform-cflags-y and platform-asflags-y is further simplified for platform config.mk.
