- avoid mixing initrd_start/initrd_start_offset: just use initrd_start and indicate it's relative.
- others minor cleanups.

Stafford Horne a2c9b17959 dts: Allow specifying initrd position and size via args
This is needed as my initrd size is much larger than the default 8mb.
Also, sometimes the kernel I build is also large, so its good to be
able to move the initrd starting position.

Florent Kermarrec 1a338b602a software/bios: add new mem_list command to list available memory regions.
This is useful to know the memory regions available and use the mem_xy commands
on them:

List the memory regions:

litex> mem_list
Available memory regions:
ROM       0x00000000 0x8000
SRAM      0x01000000 0x2000
MAIN_RAM  0x40000000 0x10000000
CSR       0x82000000 0x10000

Test 0x1000 bytes of MAIN_RAM:

litex> mem_test 0x40000000 0x1000
Memtest at 0x40000000 (4KiB)...
  Write: 0x40000000-0x40001000 4KiB
   Read: 0x40000000-0x40001000 4KiB
Memtest OK

Test speed on 0x1000 bytes of MAIN_RAM:

Stafford Horne 51327e00b5 mor1kx: Enable rotate, sign extend under linux, new fpu extension
My thought is that if we are running linux the FPGA should be able to
handle these extra instruction's footprint.  Also, since we are running
on linux there may be any kind of software running on the CPU, so allow
handling these instructions.

FPU is added bia a new +fpu extension.

But really, I am running GLIBC tests and they run faster with this
enabled.

Florent Kermarrec d90d3e043b software/liblitedram: add optional SDRAM_TEST_DISABLE that can be defined to full disable SDRAM test.
