boot0 and SPL are two different software doing the same thing.

Hi! I'm using an Olimex A20 board and would like to reduce the power consumption. I don't need the HDMI, SATA and Ethernet interfaces. Would it be possible to switch off the power for these subsystems at the regulator level?
<topi`>
mripard: is it so that you need SPL to be able to jump to uboot?
<mripard>
topi`: no, either SPL or boot0.
<topi`>
so, why is the lack of SPL a problem for sunxi, then?
<mripard>
it's allwinner's code, we don't have the source code most of the time, it's a pain to compile, etc.
<topi`>
i've noticed it's a pain to compile, using a newer compiler than gcc-4.4 gets you into trouble
<ZZambia>
2014-09-29 15:32 <Gerwin_J> end of october there will be a A80 GPU SDK
<ZZambia>
any news on that?
<mnemoc>
meaning new android blobs?

mnemoc: no, I was wondering about pure Linux support
<ZZambia>
up to now there's no official news about Linux support, only kernel and part of Uboot have been released
<ZZambia>
and the lichee branch of android 4.4
<ZZambia>
for the optimus board, at least
<hno>
ZZambia, nothing on A80 from Allwinner. Not even responding.
<ricardocrudo>
I'm trying to build the linux-sunxi 3.4 branch, but I'm getting this error: invalid 'asm': operand number out of range asm("mrc p15, 0, %0, c2, c0\n\t"
<hno>
ricardocrudo, full error please.
<mnemoc>
ZZambia: the main problem with PVR blob wise is that they sell the per-OS licenses. so allwinner would need to pay extra to produce linux blobs
<cubear>
bleh
<ZZambia>
indeed, but they announced full support for Android, Linux and even WP8
<mnemoc>
see to believe
<hno>
mnemoc, so Android is not Linux in their licensing?
<ZZambia>
hno: Android is not Linux for HW vendors
<mnemoc>
hno: the blob is not bound to the kernel, but to the display server
<ZZambia>
they only share the same (mostly) kernel
<cubear>
ricardocrudo: shouldn't that be gnueabihf?
<ZZambia>
even a bare GLES support would be sufficient
<mnemoc>
libhybris
<ZZambia>
libhybris is okay for cedar and minor stuff
<hno>
ricardocrudo, you should use a Linux toolchain to build the kernel, not a baremetal toolchain.
<ZZambia>
for display it is a nightmare
<ricardocrudo>
hno: hmm, I usually use this toolchain. I had this working before pull the repo
<hno>
ricardocrudo, that file have not changed since 2013.
<ricardocrudo>
hno: ops, I guess the problem starts to happen after I update my debian distro. sorry for the bad report
<hno>
wens, in which of the A31 SDKs is boot0/boot1 source?
<wens>
lichee/boot something

wens, ok, found it in a31_v4.5_hummingbird_kfb_ok
<hno>
but not in a31_V4.5_MerriiLinux_Humming
<topi`>
this is my observation. I first had that MerriiLinux one, and no boot0 code anywhere.
<oliv3r>
hno: thanks for merging my patch :p

oliv3r, only a year or so waiting time. Blazing fast.
<wigyori>
mripard: completely out of context, do you know an eu site where i can pick up an a31 board, f.e. a hummingbird?
<topi`>
I received a reply from Merrii while querying for my problems getting a bootable SD card.
pwhalen has quit [Quit: Leaving]
<mripard>
wigyori: in UE? nope :( I ordered mine on aliexpress
<topi`>
the response just plainly states that You can use PhoenixCard tool to boot from sdcard. and included is a .rar image of that SW
<topi`>
*sigh*
<wigyori>
mripard: i feared this answer :)
<topi`>
wigyori: my Hummingbird came from aliexpress
<topi`>
wigyori: but you should avoid the A31, it's more difficult to bringup that board than any A20 one
<wigyori>
topi`: can't really skip that, i'd want to get that supported in owrt as well
<hno>
topi`, why don't you and then modify the sdcard to your liking?
<hno>
there is some configuration of boot0 taking place when you run PhoenixCard / Livesuite.

hno: I'm not going to start running random software downloaded from the internet
<topi`>
especially because my corporate windows machine is bolted down :/
<topi`>
maybe if I'd get my hands on a JTAG debugger, it would be possible to just check all sorts of DRAM timings that are taking place at BOOT0 time and create my own reverse-engineered boot
<mripard>
topi`: SPL patches have been published yesterday, on another A31 board, but if you can access the DRAM timings and muxing informations (that you can retrieve from the fex file anyway), you can start working on it too.
<topi`>
mripard: do you know if there are any differences between that A31 board and the Merrii A31?
<hno>
topi`, every board is slighly different but what is needed by SPL is very little, basically only your DRAM settings.
<topi`>
I thought SPL also wants to be able to read from NAND (so that it can load U-boot)
<mripard>
no, it only reads from MMC. u-boot has no support for the NAND yet
<topi`>
ok

ricardocrudo: try unplugging and reconnecting the usb cable. at least on the usb midi gadget, the host only sees the gadget after the second connect...
<ricardocrudo>
mawe242: no luck here
<ricardocrudo>
I'm using sdcard as file parameter should be this the problem?
