sunxi-next branch is gone

clone-repos.sh: clone_branch git://github.com/jwrdegoede u-boot-sunxi sunxi-next

Looks like the main "sunxi" branch is the right one. That fork is also even with the upstream. Thus:

git clone git://github.com/linux-sunxi/u-boot-sunxi.git

I haven't tried building and running it yet, but I will when I can.

I don't see those commits on linux-sunxi/sunxi. However, it looks like they did get applied to the linux-sunxi/mirror/master, which looks like an old copy of the mainline U-Boot master, so we should probably switch to that.

I've updated my master branch to use the latest upstream U-Boot release:

https://github.com/talex5/xen-arm-builder

However, I had to edit the cubieboard2 boot script to move Linux to a different memory location. I guess U-Boot is now using that area for something else (possibly its stack). I couldn't find what was using it, or anything suggesting that the new address is free. Xen requires a contiguous block of memory for dom0, so either we have to put everything at the top of RAM, or everything at the bottom, and U-Boot is already using the bottom addresses.

The Cubieboard 3 might need similar updates, but I haven't tested it.

Let me know if it works for you!

It isn't convenient for me build the whole image right now, but building that version of U-Boot works, and I ran just the commands to write the .bin and .scr to the card, and it booted fine...

With the new U-Boot:

sunxi# bdinfo
arch_number = 0x100010BB
boot_params = 0x40000100
DRAM bank   = 0x00000000
-> start    = 0x40000000
-> size     = 0x40000000
eth0name    = dwmac.1c50000
ethaddr     = 02:12:0a:42:bb:28
current eth = dwmac.1c50000
ip_addr     = <NULL>
baudrate    = 115200 bps
TLB addr    = 0x7F6F0000
relocaddr   = 0x7F657000
reloc off   = 0x35657000
irq_sp      = 0x7F236EF0
sp start    = 0x7F236EE0
FB base     = 0x00000000

With the old one:

sun7i# bdinfo
arch_number = 0x000010BB
boot_params = 0x40000100
DRAM bank   = 0x00000000
-> start    = 0x40000000
-> size     = 0x40000000
eth0name    = dwmac.1c50000
ethaddr     = 02:12:0a:42:bb:28
current eth = dwmac.1c50000
ip_addr     = <NULL>
baudrate    = 115200 bps
TLB addr    = 0x7FFF0000
relocaddr   = 0x7FF86000
reloc off   = 0x35F86000
irq_sp      = 0x7FB65EF0
sp start    = 0x7FB65EE0

So the old script was overwriting the TLB and relocated U-Boot code I guess. I'm not sure why the address is different though.

I had to make changes to get this working on the cubietruck. I used the following addresses

setenv kernel_addr_r  0xaf600000 # 8M
setenv ramdisk_addr_r 0xaee00000 # 8M
setenv fdt_addr       0xaec00000 # 2M
setenv xen_addr_r     0xaea00000 # 2M

Thanks @infidel - I didn't know about that command! For future reference, here is the output on the CubieTruck:

arch_number = 0x100010BB
boot_params = 0x40000100
DRAM bank   = 0x00000000
-> start    = 0x40000000
-> size     = 0x80000000
eth0name    = dwmac.1c50000
ethaddr     = 02:0d:07:81:13:60
current eth = dwmac.1c50000
ip_addr     = <NULL>
baudrate    = 115200 bps
TLB addr    = 0xBF6F0000
relocaddr   = 0xBF656000
reloc off   = 0x75656000
irq_sp      = 0xBF235EF0
sp start    = 0xBF235EE0
FB base     = 0xBFD00000

I've updated the patch to include @Furao's settings and made a PR (#58).
