commit 1a649e859f956360dbb01b1e5e10fc6ab99f4dbd Author: Martin Roth martin@se-eng.com Date: Fri May 25 12:23:32 2012 -0600
Update SB800 CIMX FADT
- Add #define to allow the FADT PM Profile to be overridden. - Change the location of the PMA_CNT_BLOCK_ADDRESS to match current documentation. - cst_cnt should be 0 if smi_cmd == 0 - add a couple of default access sizes. - Add a couple of #define values for unsupported C2 & C3 entries. - Add PM Profile override value into amd/persimmon platform. This does not use the #defines in acpi.h so that the files that include this don't all need to start including acpi.h.
