8c79c2599f cpu/rocket/core: Initial changes for .dts generation through json2dts. 
For now just add information missing by json2dts to generate the .dts similarly to VexRiscv-SMP.

c6394c8f27 integration/builder: Add support for --soc-csv/--soc-json/--soc-svd arguments. 
Should be prefered over csr-xy since initial export was created when we were only interested
by CSR mapping export but has been extended since then to SoC mapping in general.

f84ecaf707 liblitedram/sdram_spd: do not send stop symbol 
According to the SPD specification, we shouldn't send
a stop symbol after the write that sets the address counter.

cdc1152162 liblitedram/sdram_spd: use temp_len when reading SPD 
This change should change anything from the point of view of
`sdram_read_spd` caller, but it makes it so less I2C reads are actually
hapenning.

With `len` we read too many bytes and write them to the `buf`.
In subsequent iterations we overwrite those bytes as all counters are
being updated by the `temp_len`. Nothing terrible, but too many
bytes were being read.
