I'm one of the OMAP1 Linux kernel maintainers, and I have Palm TE which I have been using for testing and development (and reporting bugs, regressions) along with those other boards you mentioned. Since I have the real Palm HW, I haven't used QEMU for that particular board. But however I use QEMU SX1 support frequently as it's quickest way to check if OMAP1 is bootable, and if the basic peripherals are working. SX1 is close to Palm/AMS-Delta, and also it's ARMv4T which is rare these days. I think it's useful to keep it in QEMU as long there are hardware that people use. So my wish is to keep at least SX1 support in QEMU as long as ARMv4T supported in the Linux kernel. > >> > > OMAP2 machines: > >> > > > >> > > n800 Nokia N800 tablet aka.

I have also these boards (real hardware) and test them frequently with mainline Linux. However, QEMU support I haven't used/needed. I recall it was a bit buggy, and some changes in mainline made the kernel unbootable. Unless Tony needs the support, I guess they are good to go. (Arnd: RAM isn't everything. Some of the OMAP1 boards today are still more useful than N800/N810, even with modern bloaty Linux.) A.
