- * Create the Fixed ACPI Description Tables (FADT) for this board.
- The FADT defines various fixed hardware ACPI information vital to an ACPI-compatible
- OS, such as the base address for the following hardware registers blocks:
- PM1a_EVT_BLK, PM1b_EVT_BLK, PM1a_CNT_BLK, PM1b_CNT_BLK,
- PM2_CNT_BLK, PM_TMR_BLK, GPE0_BLK and GPE1_BLK.
- The FADT also has a pointer to the DSDT that contains the Differentiated Definition Block,
- which in turn provides variable information to an ACPI-compatible OS concerning the base
- system design.
-
- Not all blocks are necessary usualy only PM1a, PMTMR and GPE0 are used.
