[Qemu-devel] [RFC 42/47] acpi: make tables linker-loader available to other targets |
Date: |

keeping bios-linker-loader.c i386 specific would break build
of mips target which is built with CONFIG_ACPI which would
dependend on it in following patch that adds acpi_def_block()
term. Also UEFI for ARM target is going to use linker as well
so it makes sense to move it into generic target independent
ACPI part.
