Florent Kermarrec 9e7079c4c8 targets: Remove int() on BaseSoC's sys_clk_freq. 2022-11-08 11:54:17 +01:00
Florent Kermarrec b0e6414519 targets: Cleanup arguments and switch --sys-clk-freq to float (avoid conversion in code). 2022-11-08 10:41:35 +01:00
Florent Kermarrec 16b9677acd targets: Switch to soc_core_argdict. 
The next move was to remove soc_core and only keep soc; so this is probably the right time to do
it in targets to avoid having to handle it later.
