edison-u-boot's Issues

Brillo versions completely async with U-Boot

It looks like all Brillo branches based on some strange U-Boot base, i.e. v2015.10-rc4. Perhaps, guys, you have to fix your process and how you are versioning your stuff.

U-Boot should support Edison out of the box

The custom stuff in this repository has to be upstreamed at some point, otherwise the burden of supporting x86_64 kernel boot will be on users. This is not good.

GPIO support

Hello,

I would like to know if the GPIO command inside u-boot is supported for the Edison.
I need to set some of the pins as early as possible during the boot process and since the intel IFWI is not open, u-boot should be the way.

I was able to compile the source code from the v2015.10 branch with the #define CONFIG_CMD_GPIO enable on the edison.h file and the gpio command is now available inside u-boot,b ut I cannot set or clean any of the GPIO pins. I keep getting "Command 'gpio' failed: Error -22" at every command I try.
Testing "gpio status -a" doesn't return anything.

This behavior made me believe that there is some code that make u-boot compilable with that define enable but it is not the correct code for the Edison GPIO. Am I correct?

Thanks in advance.

DFU issues

U-Boot 2015.10

When trying to open a dfu connection I get:

=> dfu 0 mmc 0
ERROR: Memory layout (mmc) not supported!

at drivers/dfu/dfu_mmc.c:389/dfu_fill_entity_mmc()
ERROR: DFU entities configuration failed!

at drivers/dfu/dfu.c:81/dfu_init_env_entities()
dfu - Device Firmware Upgrade

Usage:
dfu <USB_controller> <interface> <dev> [list|timeout]
  - device firmware upgrade via <USB_controller>
    on device <dev>, attached to interface
    <interface>
    [list] - list available alt settings
    [timeout] - specify inactivity timeout in sec, doesn't work whit list

Any hints on how to fix this?

edison-v2016.03 fails to build

make edison_defconfig
make all

Customisation of U-Boot for Edison x86

I am customising the U boot source for compiling locally to make changes in uboot source of Edison.
I have downloaded the source Edison-u-boot, and trying to build the code.
I have configured for x86 with command as following
make coreboot-x86_defconfig,

1. is it the correct config for x86 Edison board?
   and want to build the code.
   When I do make,
   getting following error.

undefined reference to `__normal___udivdi3'
make: *** [u-boot] Error 1

Please suggest and provide documentation for customising Edison Uboot.
Provide links for sources of Uboot.
