[PATCH 0/8] x86: Improve bootstd support

[Simon Glass]

This series provides some bootstd fixes so that IDE can be used reliably
for booting a distro. It also includes some documentation on how to boot
from coreboot in various scenarios, using QEMU.

With this it is possible to boot Ubuntu 2023.04 from coreboot64, for
example.


Simon Glass (8):
  usb: Return -ENOENT when no devices are found
  lib: Suppress E when writing error-string output
  bootstd: Rename bootdev_setup_sibling_blk()
  bootstd: Correct creating of bootdev sibling
  bootstd: Add some more debugging in the bootdev uclass
  x86: coreboot: Add IDE and SATA
  x86: coreboot: Enable standard boot
  x86: coreboot: Enable support for CBFS
