Hey Samuel, I think this and patch 12/12 with the defconfig changes should be deferred until post LPC (which still leaves plenty of time for making the 6.1 merge window). We already have like 4 different approaches between the existing SOC_FOO symbols & two more when D1 stuff and the Renesas stuff is considered. Plan is to decide at LPC on one approach for what to do with Kconfig.socs & to me it seems like a good idea to do what's being done here - it's likely that further arm vendors will move and keeping the common symbols makes a lot of sense to me...
