common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include at all, so remove that include. Signed-off-by: Simon Glass Signed-off-by: Tom Rini

acpi: Don't reset the tables with every new generation

2020-11-06T01:51:31+00:00

At present if SSDT and DSDT code is created, only the latter is retained for examination by the 'acpi items' command. Fix this by only resetting the list when explicitly requested. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

dm: acpi: Add support for the NHLT table

2020-07-17T06:32:24+00:00

The Intel Non-High-Definition-Audio Link Table (NHLT) table describes the audio codecs and connections in a system. Various devices can contribute information to produce the table. Add core support for this, based on a structure which is built up through calls to the driver. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner

dm: core: Add a way of overriding the ACPI device path

2020-07-17T06:32:24+00:00

Some devices such as GPIO need to override the normal path that would be generated by driver model. Add a device-tree property for this. Signed-off-by: Simon Glass Reviewed-by: Bin Meng Reviewed-by: Wolfgang Wallner

acpi: Add an acpi command to list/dump generated ACPI items

2020-07-17T06:32:24+00:00

Add a command that shows the individual blocks of data generated by each device, effectively splitting the full table into its component parts. This can be helpful for debugging. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner Reviewed-by: Bin Meng

acpi: Add support for DSDT generation

2020-07-17T06:32:24+00:00

Some devices need to inject extra code into the Differentiated System Descriptor Table (DSDT). Add a method to handle this. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner Reviewed-by: Bin Meng [bmeng: correct one typo in inject_dsdt() comments] Signed-off-by: Bin Meng

acpi: Add support for SSDT generation

2020-07-17T06:32:24+00:00

Some devices need to generate code for the Secondary System Descriptor Table (SSDT). Add a method to handle this. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner Reviewed-by: Bin Meng

acpigen: Support writing a length

2020-07-17T06:32:24+00:00

It is convenient to write a length value for preceding a block of data. Of course the length is not known or is hard to calculate a priori. So add a way to mark the start on a stack, so the length can be updated when known. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner Reviewed-by: Bin Meng

acpi: Support generation of ACPI code

2020-07-17T06:32:24+00:00

Add a new file to handle generating ACPI code programatically. This is used when information must be dynamically added to the tables, e.g. the SSDT. Initial support is just for writing simple values. Also add a 'base' value so that the table can be freed. This likely doesn't happen in normal code, but is nice to do in tests.

acpi: Move the xsdt pointer to acpi_ctx

Put this in the context along with the other important pointers. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner
