Is there git tree with u-boot for SPEAr1310 somewhere? I only seen patches from 2010...
Here a link to the ST git repository:
git://stlinux.com/spear/u-boot.git
Most branches are not based on current mainline U-Boot version though. ST people might have a better overview here.
Please note that there is currently ongoing effort to port much of this repository into mainline. From ST and from myself. Stay tuned. The list should see some updates quite soon...
Please don't hesitate if you have any specific questions.
Is there easy way to flash resulting u-boot using BDI?
My experience is mostly SPEAr600 only right now. Not sure if there are bigger differences between those SoC's in the BootROM.
I believe the spear600 is totally different from 1300. But, simple:
reset halt ; load ... ; go ...
combo should work I believe. In case you're loading some U-Boot SPL, it's very good idea to put an "asm volatile("x : b x");" line into the SPL to make the CPU loop instead of try loading uboot. Since if the CPU is looping, you can break it with BDI, if it isn't looping and jumps to some garbage, it usually ends in undefined state and bootrom might further tamper with the CPU configuration.

SPEAr600 uses XLoader as SPL. I ported U-Boot SPL for SPEAr600 though, completely obsoleting XLoader. Patches are not quite ready for the list though.
Best regards, Stefan
