the SDA/SCL pin direction, by treating the direction as just that; a hint.
Instead, configure the SDA/SCL pins as outputs only when they are to
be driven low (zero). Otherwise configure them as inputs and allow the
pull-up resistors to do their jobs.
Check the SDA direction hint only if DIAGNOSTIC.
Fixes a problem reported by Donald T Hayford on port-arm@ whereby the
kernel failed to read/write the RTC's registers.
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.
just options CPU_IN_CKSUM.
Include std.arm in all arm platform std files.
This should reenable the asm in_cksum code for all arm platforms.
Also remove the now unused in_cksum_arm.S.
- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
+ It is easy to understand that memsize is added to physcal_freeend.
+ Add VERBOSE_INIT_ARM at befor/after with printf().
+ Call ddb_init() before db_machine_init().
+ Fix declered kgdb_devrate.
+ Add INCLUDE_CONFIG_FILE and UFS_DIRHASH.
+ Add white space at file-system and enabled some file-system.
+ Comment-outed un-major devices.
+ Add stuirda, uchcom, ugensa.
