2014-12-30drivers/pc80/mc146818rtc: Assume we always have ALTCENTURYGabe Black
This patch has a rather twisted history. It was originally split off from a chromium patch, which moved ALTCENTURY to Kconfig. However, since we have no user without ALTCENTURY, we've agreed that the best way to proceed is to eliminate the non-ALTCENTURY case entirely. The old commit message and identifiers are kept below for reference: The availability of "ALTCENTURY" is now set through a kconfig variable so it can be available to the RTC driver without having to have a specialized interface. BUG=None TEST=Built and booted on Link with the event log code modified to use the RTC interface. Verified that the event times were accurate.

2014-10-22cmos: Rename the CMOS related functions.Gabe Black
Most of the code related to the mc146818 is not related to the RTC and is really for managing the CMOS storage. Since we intend to add a generic API for RTC drivers it's inconvenient for those functions to have an rtc_ prefix. This CL renames those functions so they start with cmos_ instead. There are some places where rtc_init was called with a comment that says something about starting the RTC. That wasn't correct before (the RTC is always running), but it looks a little odd now that the function is called cmos_init. This CL also opportunistically cleans up some style problems in this file.

2012-11-28Remove assembly coded log2 functionRonald G. Minnich
As we move to supporting other systems we need to get rid of assembly where we can. The log2 function in src/lib is identical to the assembly one (tested for all 32-bit signed integers :-) and takes about 10 ns to run as opposed to 5ns for the non-portable assembly version. While speed is good, I think we can spare the 15 ns or so we add to boot time by using the C version only. Change-Id: Icafa565eae282c85fa5fc01b3bd1f110cd9aaa91 Signed-off-by: Ronald G.

2011-02-12Attached patch fixes the LPC decode ranges of SB600/SB800. We enable early ↵Rudolf Marek
only Serial/SIO/RTC. Everything else needs to be done by lpc.c Problem was that early settings survived, because the lpc.c is doing ORs only... Hence we decode quite a lot and even strange ranges like IO port 0x4600 etc... Also, if some port which does not fit to predefined set is requested, like 0x290 for Hardware monitor, the wide port is done, but in our case it has range 512 bytes which means we decode in fact 0x290 - 0x490. And if we hit GPU in the 0x3bx range I receive MCE exception if I do isadump -f 0x300 which is bad. Therefore If I detect that the requested range is small (16 bytes) I additionally set the small wide io region so only 16 bytes is decoded. While at it, I fix spelling typos and I init the regs so we don't write random garbage to regs even if we don't enable them later.
