2020-01-07 09:42:00 +01:00
Drew Fustini 5d8d75f6cd add 32MB SDRAM for hadbadge
Add AS4C32M8SA-7TCN 32MB SDRAM used on cartridge PCB
by Jacob Creedon for the Hackaday Supercon ECP5 badge.

These changes were orginally made by Michael Welling:
https://github.com/mwelling/litedram

KiCad design files for the SDRAM cartridge:
https://github.com/jcreedon/dram-cart/

The SDRAM cartridge PCB is shared at:
https://oshpark.com/shared_projects/IQSl2lid

shared DigiKey cart of the parts:

Gabriel Somlo bdcecad76f init: improve legibility of generated/sdram_phy.h (cosmetic)
Use DFII_NPHASES constant (defined earlier in the file) to size the
two 'sdram_dfii_pix_[wrdata|rddata]_addr' arrays, instead of a bare
number. Additionally, ensure the first array element is indented by
a tab, same as the ones following it.

Benjamin Herrenschmidt bac66aa08f gen: In conjunction with the corresponding changes in litex itself, this will allow us to generate a more useful standalone litedram core.
The CSR alignment and base can be specified (which mostly affects
the generation of csr.h) andwe stop trying to copy the init code
that we haven't generated
