[PATCH v3 00/35] dm: Add programmatic generation of ACPI tables (part B)

[Simon Glass]

This is split from the original series in an attempt to get things applied
in chunks.

This part includes:
- writing basic ACPI code for integers, strings, names, packages
- writing descriptors for GPIO, I2C, interrupts, SPI
- writing code to enable/disable ACPI peripherals via GPIOs
- writing SSDT and DSDT tables
- additional ways to determine ACPI device names

Much of this code is taken from coreboot and I have tried to avoid
changing the original code for no reason. Changes include:
- splitting the acpi_dp functions into their own file
- adding tests
- adding (lots of) comments
- using a context pointer instead of global variables
- tidying up some code where couldn't resist (e.g. acpigen_emit_namestring())

Changes in v3:
- s/NUL/NULL/ for the NUL character, since that is in more common use
- Fix 'an GPIO is found' typo
- Update comment in acpi_device_set_i2c() to talk about scope parameter
- Make acpi_device_write_spi() static
- Add an extra comment about scope to acpi_device_set_spi()
- Use BIT() in a few places
- Resist the temptation to go to >80 characters
- Add a reference to the ACPI spec
- Add a define for the 0x80 constant
- Move the function comments into this patch
- Fix 'easy of testing' typo
- Move two function comments into the previous patch
- Allow the name parameter to be NULL
- Add error checking to acpi_dp_add_integer_array()
- Fix 'acpi_device.v' typo
- Drop unused ACPI_CPU_STRING
- Use an enum for the GPIO priority
- Add error checking
- Fix incorrect function names and arguments in commments
- Add error checking for acpi_dp_add...() functions
- Fix function name in comment for acpigen_write_not()
- Use #defines for the mask values
- Fix 'THe' typo
- Rename MAX_ITEMS to MAX_ACPI_ITEMS
- Make find_item() static and rename to find_acpi_item()
- Rename build_type() and add a comment
Drop coreboot_acpi_ids enum
- Fix 'THe' typo
- Rename build_type() to sort_acpi_item_type()
- Refactor the code to remove the extra memcpy()
- Recalculate the DSDT checksum only once
- Add a comment as to why the checksum byte is set to 0
- Fix 'of' typo
- Update acpi_dump_items() to take an enum
- Update commit message and subject for clarity

Changes in v2:
- Update to add a new 'base' field to struct acpi_ctx
- Free the memory allocated to the table and context
- Fix memset of I2C descriptor
- Fix memset of SPI descriptor

Changes in v1:
- Capitalise ACPI_OPS_PTR
- Split into more patches for review
- Add tests
- Rebase on top of common.h series
- Fix 'the an' typo
- Move header definitions into this patch
- Update sandbox driver slightly for testing
- Switch parameter order of _acpi_fill_ssdt() and make it static
- Fix 'sentinal' and 'METHOD_FILL_SDDT' typos
- Correct the commit subject
- Generalise the ACPI function recursion with acpi_recurse_method()
- Generalise the ACPI function recursion with acpi_recurse_method()
- Use OEM_TABLE_ID instead of ACPI_TABLE_CREATOR
- Update ACPI_DSTATUS enum
- Drop writing of coreboot tables
- Generalise the ACPI function recursion with acpi_recurse_method()
- Use acpi,ddn instead of acpi,desc
- Rename to acpi_device_infer_name()
- Update newly created sandbox tests
