Return to rf_archs.h CVS log

Up to [local] / sys / dev / raidframe

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)

/*
 * rf_archs.h -- Defines for which architectures you want to
 * include in some particular build of RAIDframe.  Unfortunately,
 * it's difficult to exclude declustering, P+Q, and distributed
 * sparing because the code is intermixed with RAID5 code.  This
 * should be fixed.
 *
 * This is really intended only for use in the kernel, where I
 * am worried about the size of the object module.  At user level and
 * in the simulator, I don't really care that much, so all the
 * architectures can be compiled together.  Note that by itself, turning
 * off these defines does not affect the size of the executable; you
 * have to edit the makefile for that.
 *
 * Comment out any line below to eliminate that architecture.
 * The list below includes all the modules that can be compiled
 * out.
