Intel Bay Trail FSP UPD Binding
|
|
===============================
|
|
|
|
The device tree node which describes the overriding of the Intel Bay Trail FSP
|
|
UPD data for configuring the SoC.
|
|
|
|
All properties can be found within the `upd-region` struct in
|
|
arch/x86/include/asm/arch-baytrail/fsp/fsp_vpd.h, under the same names, and in
|
|
Intel's FSP Binary Configuration Tool for Bay Trail. This list of properties is
|
|
matched up to Intel's E3800 FSPv4 release.
|
|
|
|
# Boolean properties:
|
|
|
|
- fsp,enable-sdio

|
|
|
|
If you set "fsp,enable-memory-down" you are strongly encouraged to provide an
|
|
"fsp,memory-down-params{};" to specify how your memory is configured. If you do
|
|
not set "fsp,enable-memory-down", then the DIMM SPD information will be
|
|
discovered by the FSP and used to setup main memory.
