2===============================
3
4The device tree node which describes the overriding of the Intel Bay Trail FSP
5UPD data for configuring the SoC.
6
7All properties can be found within the `upd-region` struct in
8arch/x86/include/asm/arch-baytrail/fsp/fsp_vpd.h, under the same names, and in
9Intel's FSP Binary Configuration Tool for Bay Trail. This list of properties is
10matched up to Intel's E3800 FSPv4 release.

12# Boolean properties:
13
14- fsp,enable-sdio
15- fsp,enable-sdcard
16- fsp,enable-hsuart0

39- fsp,igd-render-standby
40- fsp,txe-uma-enable
41- fsp,emmc45-ddr50-enabled
42- fsp,emmc45-hs200-enabled
43- fsp,enable-igd
44- fsp,enable-memory-down
45
46If you set "fsp,enable-memory-down" you are strongly encouraged to provide an
47"fsp,memory-down-params{};" to specify how your memory is configured. If you do
48not set "fsp,enable-memory-down", then the DIMM SPD information will be
49discovered by the FSP and used to setup main memory.
