riscv: Include bss subsections in linker script

2018-08-20T12:25:59Z

When we build with -fdata-sections we may end up with bss subsections. Our linker script explicitly lists only a single consecutive bss section though. Adapt the statement to also include subsections. Signed-off-by: Alexander Graf

efi_loader: Rename sections to allow for implicit data

2018-07-25T12:57:44Z

Some times gcc may generate data that is then used within code that may be part of an efi runtime section. That data could be jump tables, constants or strings. In order to make sure we catch these, we need to ensure that gcc emits them into a section that we can relocate together with all the other efi runtime bits. This only works if the -ffunction-sections and -fdata-sections flags are passed and the efi runtime functions are in a section that starts with ".text". Up to now we had all efi runtime bits in sections that did not interfere with the normal section naming scheme, but this forces us to do so. Hence we need to move the efi_loader text/data/rodata sections before the global *(.text*) catch-all section. With this patch in place, we should hopefully have an easier time to extend the efi runtime functionality in the future. Signed-off-by: Alexander Graf [agraf: Fix x86_64 breakage]

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
