gowin: add hack for copackaged PSRAM
 2022-01-23 08:33:29 +01:00
Icenowy Zheng b7b054d48e gowin: add hack for copackaged PSRAM 
Some Gowin FPGAs has copackaged "PSRAM" instead of "HyperRAM". They're
in fact also HyperRAM, but named differently and because of this needs
slightly changed hack.

Add hack for PSRAM too. In case of two PSRAM chips are used, the bus is
wider so the needed definition is already in place, so the bus width
hack is not needed.

Stafford Horne d1746e1286 tools/litex_json2dts_linux.py: Support DTS generator for OpenRISC marocchino 
Marocchino is also a or1k architecture and the DTS file is the same
as mor1kx.  I would like to use the dts generator for marocchino too.

This patch introduces a new mapping to derive architecture based on the
cpu_name it then uses the cpu_arch (architecture) to control the DTS
generation rather than the cpu name.

Stafford Horne d3942c137d bios/boot: Support setting EVBAR for Marocchino too 
The Marocchino CPU is an OR1K architecture so it also requires setting
of EVBAR to boot linux.
