[U-Boot] u-boot.git or u-boot-x86.git for x86_64 u-boots?

[Joakim Tjernlund]

I found two repos w.r.t x86_64 for u-boot, which one should I use?

I am ATM only looking at USING the qemu-x86 target for now.

BTW, I found tools/binman/binman.py only worked with python 2.7, maybe you can change
the shebang to python2.7 as my default python is 3.4

U-Boot x86_64 support is not in mainstream yet.

So I should use u-boot-x86.git for now then.
Strangely u-boot.git did work too.

u-boot.git is the mainstream repo while u-boot-x86.git is the x86 repo
which has WIP patches and queued to be pulled into u-boot.git

I'll be sending v3 fairly soon. But even then it is not complete.
Various things need fixing up and polishing - e.g. SDRAM sizing,
graphics ROMs, actually booting Linux!

We should probably patch it to work on 3.4 also.

Great, getting closer every day.
Any idea for how much is missing in u-boot to bring up a 
Rangeley(C2758), no graphics required. Need networking, rs232, USB and maybe SATA.

The effort won't be too much as Intel has an FSP for Rangeley.

If it uses an FSP then it probably isn't much work to get it running
with 32-bit U-Boot. Bin is the expert here.

For 64-bit, we have quite a few things to do. But note that 32-bit
U-Boot can directly boot both 32-bit and 64-bit kernels. It does not
have the 'UEFI' restriction of having to select your boot loader based
on your kernel.

I did a quick test using: 2to3 -w binman.py

This makes binman.py "build" on both 2.7 and 3.4 but running it on 3.4
hangs forever until Ctrl-C:

Please just change shebang to python2.7 for now. This is the only fix needed
to build the x86 qemu target.
