  • ⚠️ remove XBUS_BIG_ENDIAN top generic; the external bus interface is - just like the entire processor - little-endian only
  • ⚠️ remove VENDOR_ID generic, replace by JEDEC_ID: this generic only specifies the JEDEC's bank number (number of continuation codes modulo 16) plus the least-significant 7 bits of the actual manufacturer ID; this value is also passed to the DTM's IDCODE JTAG register
  • ⚠️ rearrange bits in SYSINFO's SOC register; transparent edit as the C defines are also updated
  • ⚠️ rename physical memory protection extension MXISA flag and ISA extension name: PMP -> SMPMP
  • 🧪 add all main memory sections to linker script (just for completeness): ram, rom, xip, boot, io
