commit 7eedd07ca9bc4af28bf7c36b07276b6d7efe60f1 Author: Martin Roth martin.roth@se-eng.com Date: Tue Dec 2 10:49:21 2014 -0700
fsp_baytrail: update to add the UPD_MEMDOWN_CHECK macro
- Update chipset_fsp_util.h to add the UPD_MEMDOWN_CHECK pointing into the PcdMemoryParameters structure. This is baytrail FSP specific, so it's put into the chipset code instead of the 'driver' code. Since some of the values need to be decremented and some do not, a second parameter was added to control this. This macro also does not print out the values as they are printed out separately if memory down is enabled. - Update chipset_fsp_util.c to use the UPD_MEMDOWN_CHECK macro. This makes the code more standardized and easier to read.
