Revision 1.1.1.1 (vendor branch), Tue Mar 4 16:16:08 2008 UTC (16 years, 3 months ago) by nbrk
Import of OpenBSD 4.2 release kernel tree with initial code to support Jornada 720/728, StrongARM 1110-based handheld PC. At this point kernel roots on NFS and boots into vfs_mountroot() and traps. What is supported: - glass console, Jornada framebuffer (jfb) works in 16bpp direct color mode (needs some palette tweaks for non black/white/blue colors, i think) - saic, SA11x0 interrupt controller (needs cleanup) - sacom, SA11x0 UART (supported only as boot console for now) - SA11x0 GPIO controller fully supported (but can't handle multiple interrupt handlers on one gpio pin) - sassp, SSP port on SA11x0 that attaches spibus - Jornada microcontroller (jmcu) to control kbd, battery, etc throught the SPI bus (wskbd attaches on jmcu, but not tested) - tod functions seem work - initial code for SA-1111 (chip companion) : this is TODO Next important steps, i think: - gpio and intc on sa1111 - pcmcia support for sa11x0 (and sa1111 help logic) - REAL root on nfs when we have PCMCIA support (we may use any of supported pccard NICs) - root on wd0! (using already supported PCMCIA-ATA) |
