At present lpe/lpss-sio/scc FSP properties are all boolean, but in fact for "enable-lpe" it has 3 possible options. This adds macros for these options and change the property from a boolean type to an integer type, and change their names to explicitly indicate what the property is really for.

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
|
|
- fsp,enable-sdcard
|
|
- fsp,enable-hsuart0
|
|
- fsp,enable-hsuart1
|
|
- fsp,enable-spi
|
|
- fsp,enable-sata
|
|
- fsp,enable-azalia
|
|
- fsp,enable-xhci
|
|
- fsp,enable-dma0
|
|
- fsp,enable-dma1
|
|
- fsp,enable-i2-c0
|
|
- fsp,enable-i2-c1
|
|
- fsp,enable-i2-c2
|
|
- fsp,enable-i2-c3
|
|
- fsp,enable-i2-c4
|
|
- fsp,enable-i2-c5
|
|
- fsp,enable-i2-c6
|
|
- fsp,enable-pwm0
|
|
- fsp,enable-pwm1
|
|
- fsp,enable-hsi
|
|

|
|
- fsp,emmc45-hs200-enabled
|
|
- fsp,enable-igd
|
|
- fsp,enable-memory-down
|
|
|
|
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.
|
|
|
|
|
|
# Integer properties:
|
|
|
|
- fsp,mrc-init-tseg-size

|
- fsp,mrc-init-mmio-size
|
|

|
|
- fsp,mrc-init-spd-addr2
|
|
- fsp,emmc-boot-mode
|

# Boolean properties:

For all integer properties, available options are listed in fsp_configs.h in
|
|
arch/x86/include/asm/arch-baytrail/fsp directory (eg: MRC_INIT_TSEG_SIZE_1MB).
