Revision 1.1.1.1 (vendor branch), Tue Mar 4 16:16:09 2008 UTC (16 years, 3 months ago) by nbrk
Branch: OPENBSD_4_2_BASE, MAIN
CVS Tags: jornada-partial-support-wip, HEAD Changes since 1.1: +0 -0 lines
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)

/*
* Definitions needed to perform bad sector revectoring ala DEC STD 144.
*
* The bad sector information is located in the first 5 even numbered
* sectors of the last track of the disk pack. There are five identical
* copies of the information, described by the dkbad structure.
*
* Replacement sectors are allocated starting with the first sector before
* the bad sector information and working backwards towards the beginning of
* the disk. A maximum of 126 bad sectors are supported. The position of
* the bad sector in the bad sector table determines which replacement sector
* it corresponds to.
*
* The bad sector information and replacement sectors are conventionally
* only accessible through the 'c' file system partition of the disk. If
* that partition is used for a file system, the user is responsible for
* making sure that it does not overlap the bad sector information or any
* replacement sectors.
