Florent Kermarrec c0bc94ca1c soc/sdram: add capability to share L2 cache in multi-CPU SoCs 2015-06-17 15:48:45 +02:00
Florent Kermarrec 3b9f287bab sdram: use wishbone cache as L2 cache and add optional L2 cache to Minicon 2015-06-17 15:30:30 +02:00
Florent Kermarrec a1f7ecc8c5 litesata: use 200MHz clock and SATA3 (6.0Gb/s) on all example designs: working :) 2015-06-10 12:15:59 +02:00
Florent Kermarrec 571ce5791a litesata/phy/k7: apply AR# 63869 to keep CDR in hold during SATA link initialization
self.rxelecidle is already filtered so the "20 USRCLK cycles before setting RXCDRHOLD to 1'b0" are respected.

Florent Kermarrec cd3a51ada6 litescope: fix missing source ack on LiteScopeWishboneBridge 2015-05-01 20:44:57 +02:00
Florent Kermarrec 1281a463d6 litescope/bridge: create a generic wishbone bridge that can be used with different phys (the phy needs to provide a sink/source with 8bits data).
- we can now pass a phy to LiteScopeWishboneBridge
- LiteScopeUART2Wishbone is only a specific LiteScopeWishboneBridge
- UART mux is removed since complicated and no longer useful (we can now create easily virtual UART over Ethernet, USB or PCIe) or simply add another UART for debug.
