Hi, I own JMB363 SATA/IDE. I figured it out how to flash it with a flashrom. It has the parallel flash which is 512KiB (SST39VF040), but the memory BAR where the flash is visible is only 64KiB. How flashrom deals with such programmers? It looks like I just need to mask the address bits not to get out of the BAR. Maybe I need to use "layout" feature? Has someone else the jmicron SATA/IDE controller? I guess we could support similar controllers. Thanks Rudolf

Hi, I'm attaching the support for some of the JMICRON SATA controllers. The skeleton was taken form the ITE8212 driver, hence the original authors are preserved. Thanks Rudolf
