[PATCH 00/34] x86: Enhancements for booting from coreboot

[Simon Glass]

This series contains various changes to improve U-Boots Coreboot
Filesystem (CBFS) implementation and the overall booting of U-Boot from
coreboot:

- CBFS compression, bare CBFSs
- More coreboot sysinfo parsing
- Command to display coreboot sysinfo
- Various other minor things
- Additional features for booting a coral image from coreboot

These core changes are required to allow the 'coral' U-Boot to run on top
of coreboot and complete the Chromium OS verified boot flow.


Simon Glass (34):
  x86: coral: Free the ACPI GPIOs after using them
  x86: coral: Add information about building / running
  x86: p2sb: Drop LOG_DEBUG
  x86: Probe device if needed in intel_gpio_xlate()
  x86: coral: Put the eMMC first
  x86: coral: Update the SD card-detect GPIO
  tegra: i2c: Drop LOG_DEBUG
  mmc: pci_mmc: Set up the card detect
  cbfs: Add support for attributes
  cbfs: Rename new_node to node
  smbios: Allow writing to the coreboot version string
  cbfs: Allow access to CBFS without a header
  cbfs: Allow file traversal with any CBFS
  cbfs: Factor out filling a cache node into a new function
  cbfs: Simplify file iteration
  cbfs: Support reading compression information
  cbfs: Drop unnecessary cast in file_cbfs_fill_cache()
  x86: Make coreboot sysinfo available to any x86 board
  x86: Move coreboot timestamp info into coreboot_tables.h
  x86: coreboot: Sync up timestamp codes
  x86: Move coreboot sysinfo parsing into generic x86 code
  x86: coreboot: Update parsing of the latest sysinfo
  x86: Allow installing an e820 when booting from coreboot
  x86: Add a command to display coreboot sysinfo
  cmd: Add missing check for CONFIG_SYS_LONGHELP
  video: Fix video on coreboot with the copy buffer
  x86: video: Allow coreboot video to be used on any x86 board
  x86: fsp: Don't enable FSP graphics if booted from coreboot
  dm: core: Add CBFS support to flashmap
  x86: coral: Avoid build error with !CONFIG_ACPIGEN
  x86: coral: Allow init of debug UART in U-Boot proper
  x86: coral: Fall back to coreboot video when FSP missing
  x86: fsp: Don't notify if booted from coreboot
  x86: coreboot: Don't setup MTRR when booting from coreboot
