riscv: dts: Sync DT with Linux Kernel

2018-05-29T06:45:03Z

Use same dts to boot U-Boot and RISC-V Linux Kernel v4.16-rc2 in ax25-ae350 platform. Signed-off-by: Rick Chen Signed-off-by: Rick Chen Cc: Greentime Hu

riscv: cpu: nx25: Rename as ax25

2018-05-29T06:45:02Z

Andes has rearranged the product combinations. nx25 and ax25 both are RISC-V architecture cpu core. But ax25 has MMU unit inside, and nx25 is not. Cpu nx25 and platform ae250 are arranged in pairs. Cpu ax25 and platform ae350 are arranged in pairs. This patch will rename nx25 as ax25 ae250 as ae350 nx25-ae250 as ax25-ae350 including filename, variable, string and definition. Then u-boot can boot linux kernel in ae350 platform reasonably. Signed-off-by: Rick Chen Signed-off-by: Rick Chen Cc: Greentime Hu

efi_loader: Enable RISC-V support

2018-05-29T06:43:12Z

We have almost all pieces needed to support RISC-V UEFI binaries in place already. The only missing piece are ELF relocations for runtime code and data. This patch adds respective support in the linker script and the runtime relocation code. It also allows users to enable the EFI_LOADER configuration switch on RISC-V platforms.

riscv: Add board_quiesce_devices stub

2018-05-29T06:43:12Z

This patch adds an empty stub for board_quiesce_devices() which allows boards to quiesce their devices before we boot into an OS in a platform agnostic way. Signed-off-by: Alexander Graf

riscv: Add EFI application infrastructure

2018-05-29T06:43:12Z

The hello world binary and a few selftests require to build EFI target binaries, not just the EFI host environment. This patch adds all required files to generate an EFI binary for RISC-V. Signed-off-by: Alexander Graf

riscv: Enable function sections

2018-05-29T06:43:12Z

The linker can remove sections that are never addressed, so it makes a lot of sense to declare every function as an individual section. This reduces the output U-Boot code size by ~30kb for me. Signed-off-by: Alexander Graf

riscv: Add setjmp/longjmp code

2018-05-29T06:43:12Z

To support efi_loader we need to have platform support for setjmp/longjmp. Add it here. Signed-off-by: Alexander Graf

riscv: Define PLATFORM__CLEAR_BIT for generic_clear_bit()

2018-05-16T01:44:05Z

riscv bitops.h provides a __clear_bit() but does not define PLATFORM__CLEAR_BIT as a result generic_clear_bit() is used instead of the architecturally provided __clear_bit(). This patch defines PLATFORM__CLEAR_BIT which means that __clear_bit() in riscv bitops.h will be called whenever generic_clear_bit() is called - as opposed to the default cross-platform generic_clear_bit().
