Stafford Horne 3067c57080 mor1kx: Enable gcc compiler flag for cmov 
We enable this instruction so use it.

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. 
This is useful in simulation where SDRAM contents is pre-initialized from files (ex Linux-on-LiteX-Vexriscv).

Florent Kermarrec 4092180662 tools/lxterm/json: json file provide relative path, add json file directory to image names. 
Allow sharing same json file between serial boot and Ethernet/SDCard/SATAboot:

boot.json:
{
	"Image":        "0x40000000",
	"rv32.dtb":     "0x40ef0000",
	"rootfs.cpio":  "0x41000000",
	"opensbi.bin":  "0x40f00000"
}

If boot.json and images are located in images directory, using lxterm --images=images/boot.json
will now work.

Florent Kermarrec c6fb9ef939 software/liblitedram: limit clk/cmd scan to 1/2 tCK. 
Restrict the clk/cmd scan to 1/2 tCK since the full scan is not required
and in some cases can compromise the calibration with the wrong best clk/cmd
value selection.

This should also allow using cmd_latency=0 in all cases.
