2013-02-25AMD Southbridge: Add RTC init to lpc_initMike Loptien
Adding RTC init code to the Southbridge initialization code in 'lpc_init'. This initializes the RTC so that the Date Alarm register is set to a valid value (0x00) at startup. By setting the Date Alarm register to 0x00, it does not get evaluated along with the seconds, minutes, and hours when running 'fwts s3'. Information about fwts (Firmware Test Suite) can be found here: https://wiki.ubuntu.com/Kernel/Reference/fwts This is the same edit made to the CIMX SB800 titled 'AMD/Persimmon: Add RTC init to CIMX SB800' with commit ID: c4d3d which can be viewed here: http://review.coreboot.org/#/c/2488/ Change-Id: Iddb7a3cbabe736b511cde03d7dc0a4a0b1c7fd90 Signed-off-by: Mike Loptien <mike.loptien@se-eng.com> Reviewed-on: http://review.coreboot.org/2510 Reviewed-by: Martin Roth <martin.roth@se-eng.com> Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org> Tested-by: build bot (Jenkins) Reviewed-by: Dave Frodin <dave.frodin@se-eng.com>
2012-12-12Fix SPI BAR special case in lpc_set_resourcesMartin Roth
There was already a special case for the SPI base address in lpc_set_resources for southbridge/amd/cimx/sb800 and southbridge/amd/agesa/hudson, but it needed to be modified to keep from killing the IMC rom during initialization. As soon as the BAR is disabled by setting the new base address, the IMC dies. The fix is to make sure it's still enabled when setting the new base address instead of setting the new address then re-enabling it. Change the name SPIROM_BASE_ADDRESS to SPIROM_BASE_ADDRESS_REGISTER to more accurately describe what we're using.

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.
