[U-Boot] uboot information

[Sébastien Basset]

hi,

i see controller:

       src/soc/intel/braswell/chip.c/enable_dev ( Intel Braswell SoC ),
type: 2
       vendor: 0x8086. device: 0x2296
       class: 0x08 Generic system peripheral
       subclass: 0x05 SD Host controller
       prog: 0x01
       revision: 0x35
       src/soc/intel/braswell/southcluster.c/southcluster_enable_dev (
Intel Braswell SoC )
       PCI: 00:12.0 [8086/2296] ops
       PCI: 00:12.0 [8086/2296] enabled

but i can't test sdcard in coreboot ...

i had intel back on this issue, on braswell 3160 version, it's not possible
of boot on sdcard :
It can be found on page 31 of the Braswell** Design In for The Internet of
Things (IoT) document 555139.

it's very strange !!??

else i try to boot on usb:

I added node in dts file :

        usb at 14,0 {
            reg = <0x000a0000 0 0 0 0>;
            compatible = "xhci-pci";
        };

is there another step for see controller with usb start command ?

Thank you for your information.
