afaerber: personally i wouldn't enable mmc1. it's used for wifi and requires some other regulators
mripard: yep. btw, I have a question. now that I'm going to prettyfy the code.. there are two control registers in SRAM with bits for different purposes. I need to poke one of these bits. wens has proposed to represent these registers with syscon regmap.
wens, oh! I thought those were SD and eMMC... o:-/

hlavery1: the mainline one should be working
I don't have that board, so I don't know whether it works or not.
mripard: OK, thanks. It doesn't work, but I'll keep poking at it.
arokux, I'll be back later and see and replays
astr: sorry, I will not be able to help...
ok thanks for your time
hlavery1: so on your hackberry ethernet actually works with mainline ?

lioka: what happened, ethernet worked in mainline a year ago. did it break?
lioka: somebody should run git bisect

Well, I did have to modify the dts/dtb and set reg = <1> under mdio@01c0b080
This had no effect on USB power; there is none <0> or <1> in that spot.

hlavery1: which hw revision your hackberry is ?
I have small guide how to do git bisect, if somebody is interested

looking at the usb-boot script of sunxi-tools I can see some "fel write" to specific addresses (0x4a000000, 0x43000000, ...) I checked the A20 datasheet and I can't find any specific reference to this addresses. They are in the DDR-II/DDR-III range. What this addresses mean (any documentation)? the fel command is writing to sdcard or nand?

ricardocrudo, it's copying files to more-or-less "random" addresses of RAM

regarding mmc1 is it not used for the full size mmc slot on some olimex boards?
that it needs special regulators when connected to onboard wifi is one thing but it could work as standard mmc without anything special, could it not?
afaerber: sure, and after that...?
ricardocrudo, exec invokes execution at that address. U-Boot environment or boot.scr tells it to load kernel etc. from specific addresses :)
