[PATCH v2 00/16] x86: Various minor enhancements for coreboot

[Simon Glass]

This series includes some patches generated while getting U-Boot to boot
more nicely on Brya, an Adler Lake Chromebook.

This includes:
- show the ACPI tables with 'acpi list'
- get the UART to work even if coreboot doesn't enable it
- show unimplemented sysinfo tags
- fix for keyboard not working
- fix for trying to set up PCI regions when the info is not available
- fix for looking at inaccessible memory to find the sysinfo table

Changes in v2:
- Don't show an invalid CPU number on error
- Update commit message with more detail
- Update code comment to mention that addresses <1KB are ignored
- Flush the buffer instead of skipping the reset
- Add new patch to create a new Kconfig for ACPI
- Add new patch to move acpi-table-finding functions into the library
- Use tab instead of space in header file
- Refactor two patches into one
- Add new patch to allow locating the UART from ACPI tables
- Expand commit message to explain this is for the debug UART
- Update the defconfig instead
- Drop patch 'usb: Quieten a debug message' since it was fixed elsewhere
- Drop patch 'x86: coreboot: Use a memory-mapped UART' (not needed)
- Add new patch to enable ms command
- Move this patch to last in the series, so it can be dropped if needed
