2012-03-29Detect whether the OXPCIE card is really present while in the ROM stage.Gabe Black
Use an int in CAR global data to store whether or not the OXPCIE serial card is actually there. Also, time out if the card doesn't show up quickly enough, don't continue initialization if it's not there, and don't make the initialization routine default to a card if none is found.

2011-07-12Do full flush on uart8250 only at end of printk.Kevin O'Connor
The previous code does a full flush of the uart after every character. Unfortunately, this can cause transmission delays on some serial ports. This patch changes the code so that it does a flush at the end of every printk instead of at the end of every character. This reduces the time it takes to transmit serial messages (up to 9% on my Asrock e350m1 board). It also makes the transmission time more consistent which is important when performing timing tests via serial transmissions.

2010-12-17drop one more version of doing serial uart output differently.Stefan Reinauer
coreboot made it kind of complicated to print a character on serial. Not quite as complicated as UEFI, but too much for a good design. Fix it.

2004-03-11- Moved hlt() to it's own header.Eric Biederman
- Reworked pnp superio device support. Now complete superio support is less than 100 lines. - Added support for hard coding resource assignments in Config.lb - Minor bug fixes to romcc - Initial support for catching the x86 processor BIST error codes. I've only seen this trigger once in production during a very suspcious reset but... - added raminit_test to test the code paths in raminit.c for the Opteron - Removed the IORESOURCE_SET bit and added IORESOURCE_ASSIGNED and IORESOURCE_STORED so we can tell what we have really done. - Added generic AGP/IOMMU setting code to x86 - Added an implementation of memmove and removed reserved identifiers from memcpy - Added minimal support for booting on pre b3 stepping K8 cores - Moved the checksum on amd8111 boards because our default location was on top of extended RTC registers - On the Hdama added support for enabling i2c hub so we can get at the temperature sensors. Not that i2c bus was implemented well enough to make that useful. - Redid the Opteron port so we should only need one reset and most of memory initialization is done in cpu_fixup. This is much, much faster. - Attempted to make the VGA IO region assigment work. The code seems to work now... - Redid the error handling in amdk8/raminit.c to distinguish between a bad value and a smbus error, and moved memory clearing out to cpufixup. - Removed CONFIG_KEYBOARD as it was useless. See pc87360/superio.c for how to setup a legacy keyboard properly. - Reworked the register values for standard hardware, moving the defintions from chip.h into the headers of the initialization routines. This is much saner and is actually implemented. - Made the hdama port an under clockers BIOS. I debuged so many interesting problems. - On amd8111_lpc added setup of architectural/legacy hardware - Enabled PCI error reporting as much as possible. - Enhanded build_opt_tbl to generate a header of the cmos option locations so that romcc compiled code can query the cmos options. - In romcc gracefully handle function names that degenerate into function pointers - Bumped the version to 1.1.6 as we are getting closer to 2.0 TODO finish optimizing the HT links of non dual boards TODO make all Opteron board work again TODO convert all superio devices to use the new helpers TODO convert the via/epia to freebios2 conventions TODO cpu fixup/setup by cpu type git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1390 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
