Note: This is part D of this effort. With this, Coral includes all required ACPI tables.

At present on x86 U-Boot supports creating ACPI (Advanced Configuration and Power Interface) tables using the Intel ACPI Source Language (ASL) compiler.

This is good enough for basic operation but some devices need to add their information dynamically at runtime. An example is a device that needs to report its enable GPIO. This is described in the device tree, so we want to add code in the driver to convert that device-tree description into an ACPI description for use on Linux.

This series adds support for generation of ACPI tables and fragments by devices. The core support is built into driver model.

Several files are brought over from coreboot to do the actual generation.

As an example of using this new feature, chromebook_coral is updated to write out a wide array of ACPI tables including DSDT and SSDT.

This initial version of the series lays out the general approach. More work is needed to figure out the difference between CONFIG_ACPIGEN and CONFIG_GENERATE_ACPI_TABLE with respect to what is built.

Changes in v2: - Add new patch to allow more space for U-Boot on link - Add new patch to move include of bitops out of ACPI region - Rebase to master - add new patch to fix polarity type in acpi_dp_add_gpio()

Changes in v1: - Add NHLT audio support - Add NHLT information - Add comments - Add more comments and rename cpu_get_bus_clock to cpu_get_bus_clock_khz() - Add new patch with coral audio descriptor files - Add support for NHLT table - Adjust implementation to match new ACPI GPIO generation - Capitalise ACPI_OPS_PTR - Don't build for SPL - Drop unnecessary callbacks - Fix i2c PCI addresses - Handle table generation without callbacks - Move ASL_REVISION define into this patch - Move acpi_create_dbg2() into generic code - Move the acpi.h header file to this commit - Move this code into an x86-specific file - Put this code in an x86-specific place and update commit message - Rename acpi-probed to linux,probed - Rename cpi,hid-desc-reg-offset to hid-desc-addr - Split PCT and PTC tables into a separate patch - Support hid-over-i2c separately as well - UIse hid-over-i2 compatible string - Update ACPI ordering to include multiple CPUs - Update commit message - Update commit message with a comma - Update for acpi_device_write_i2c_dev() return-value change - Use OEM_TABLE_ID instead of ACPI_TABLE_CREATOR - Use SHIFT and MASK for defines - Use acpi,ddn instead of acpi,desc - Use this file in APL - Use updated acpi_device_write_dsm_i2c_hid() function
