[U-Boot] [PATCH v2 10/51] x86: Create a common header for Intel register access

2016-03-11 Thread Simon Glass
There are several blocks of registers that are accessed from all over the code on Intel CPUs. These don't currently have their own driver and it is not clear whether having a driver makes sense. An example is the Memory Controller Hub (MCH). We map it to a known location on some Intel chips (mostl
