 Problem with Raspberry Pi is that it's rather difficult to understand the SoC,
and its software support is pretty unusual (i.e., far from upstream).

 That's a SoC, not a board. There are a bunch of devboards with the processor,
but can you still get them? Probably the at91sam9g45m10ek or
atmel_sama5d3_xplained are a better fit.

 The MIPS creator CI20 is also nice. But that's not ARM, of course.

 These things are _not_ something I would advise for an absolute beginner.
Experienced consultants like me plan two to four weeks of full-time work for
porting everything from a devboard to a custom board. So starting from scratch
is definitely an ambitious goal.

Start out with just building and installing the boot loader, kernel and rootfs
for which support already exists. Then maybe you can bump the U-Boot and kernel
version (and contribute patches, of course).

 Anyway, any devboard you can get probably already has U-Boot and kernel
support, otherwise they wouldn't be able to sell it. So unless you're developing
a custom board, re-implementing those from scratch is just duplicate work.
