2019-10-21Clean up linker scriptAnish Athalye
This patch does the following: - Add .text.* to the .text section in the output - Add an assertion that the trampoline does not overflow a page - Add the .rodata section - Make .sdata and .sdata.* (which is for small data) be absorbed into the .data section, because we don't need to distinguish between them; this prevents .sdata from appearing in the output - Make the analogous change for .srodata and .sbss - Make all the data sections 16-byte aligned This patch also updates the .editorconfig for *.ld files.

2019-09-13add `-bios none' to silence qemuXi Wang
QEMU 4.1+ emits warnings if -bios is not given, as newer versions will load the OpenSBI firmware in this case. Pass `-bios none' to avoid this issue.
