The patch is against current CVS (or 0.9.0) and you can find it at http://www.zabor.org/balrog/qemu-pxa270-and-more.patch (450 kB). PXA is a series of embedded processors used in PDAs, mobile phones and other devices. PXA is an ARM based system-on-chip. 27x is the newest out of the ones produced by Intel. PXA 25x and 260 devices can be emulated using the same code. Main additions are: - On-chip peripherals: DMA, interrupt controller, GPIOs, sysem timers, memory manager, clocks manager, power manager, LCD controller, PCMCIA cards controller, MMC/SD host controller, I2C device, USB host (OHCI), I2S controller, SSP controller, UARTs, an RTC. - NAND memory emulation - should work for all chips supported by Linux given the ID of the chip to emulate (small or large page). - PCMCIA bus with hotplugging (added "info pcmcia" command for listing sockets and inserted cards). - an IBM/hitachi microdrive, reuses existing IDE code adding the CF-ATA command set. - ADS7846 touchscreen controller from Texas Instruments (used in maaany PDAs). - Wolfson WM8750 audio codec chip (I2C slave). - Maxim MAX1111 ADC chip. - Maxim MAX7310 gpio expander chip (I2C slave). - SD card emulator (unchanged from the omap support patch) - iwMMXt coprocessor support (untested). - some bugfixes. I'm posting this as is because I won't have time to make a final clean-up and I was asked for it by some persons who want to emulate pxa270 based devices. I also want to avoid duplicating code. One case of duplication is the I2C bus, there was a different I2C bus recently merged in qemu. Our implementation is slightly more detailed (as need by some I2C hosts) and does some buffering, but is 8-bit only. (hw/i2c.h should probably be made into a template that implements 8 and 16 bit i2c included two time from vl.h). Regards, Andrew
