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.

2011-06-22Add the coreboot config to CBFSCristian Măgherușan-Stanciu
The CBFS will contain a new file, named 'config' of type 'raw' that is a stripped-down version of the .config file that was used to build the current coreboot image. For space savings, all the comments and empty lines were removed from the original config, except for one that lists the coreboot git revision that's built into the image. This is done in order to easily reproduce the work of someone else when only having their ROM image. In theory the reproduce could even be automated by a new dedicated make target. This should work even with abuild now.

2011-04-19Recently the 3 projects using the new AMD reference code have beenScott Duplichan
failing the check for globals (or statics) in romstage. This causes ASRock E350M1, AMD Inagua, and AMD Persimmon builds to fail with the message "Do not use global variables in romstage". The message is working as intended. It is detecting data declared as 'static' when 'static const' was intended. The code executes correctly because it never tries to modify the data. To make reference code updates easy, it is probably best to avoid modifying the AMD provided code if possible. The following change bypasses the "Do not use global variables in romstage" check for the AMD reference code only.

2011-03-08Move cmos.default handling to bootblockPatrick Georgi
The cmos.default code wasn't actually used so far, due to an oversight when forward-porting this feature from an old branch. - Extend walkcbfs' use by factoring out the stage handling into C code. - New sanitize_cmos() function that looks if CMOS data is invalid and cmos.default exists and if so overwrites CMOS with cmos.default data. - Use sanitize_cmos() in both bootblock implementations. - Drop the need to reboot after writing CMOS: CMOS wasn't used so far, so we can go on without a reboot. - Remove the restriction that cmos.default only works on CAR boards. - Always build in cmos.default support on boards that USE_OPTION_TABLE.

2011-02-07Reliably build arbitrary Kconfig-based revisions of SeaBIOSPeter Stuge
Reliability is accomplished by checking out the desired SeaBIOS commitish into a branch named 'coreboot' in the local SeaBIOS git repository. Using a branch allows TAG-$(CONFIG_SEABIOS_..) to refer to any commitish in the SeaBIOS git repo, not just branches and tags. Configuration is done with make defconfig followed by enabling and disabling of the relevant coreboot-specific SeaBIOS options by appending to .config using echo. This works, because later entries in .config will overwrite earlier ones.

2011-01-30Inverse two arguments of cbfs-files-y and adapts its users (one of which ↵Patrick Georgi
already used the new order) This is in reponse to feedback that the original setup was too complicated. New cbfs-files-y behaviour: cbfs-files-y contains the names of files as they appear in CBFS. The arguments describe the on-filesystem name, the type and (optionally) the position. Example: cbfs-files-y += foo foo-file := bar foo-type := splashscreen foo-position := 0xffff8000 This configures a CBFS file called "foo" that is marked "splashscreen", located at 0xffff8000 in flash and contains the data of the file "bar" in the filesystem (either in the current directory, ie. where the corresponding Makefile.inc resides, or if that doesn't exist, relative to the toplevel directory).

2010-12-16Get mptable OEM/product ID from kconfig variables.Uwe Hermann
We currently use "COREBOOT" unconditionally as the "OEM ID" in our mptable.c files, and hardcode the mainboard name in mptable.c like this: mptable_init(mc, "DK8-HTX ", LAPIC_ADDR); However, the spec says "OEM ID: A string that identifies the manufacturer of the system hardware." (Table 4-2, page 42) so "COREBOOT" doesn't match the spec, we should use the hardware vendor name. Thus, use CONFIG_MAINBOARD_VENDOR which we have already as the "OEM ID" (truncate/fill it to 8 characters as per spec). Also, use CONFIG_MAINBOARD_PART_NUMBER (the board name) as "product ID", and truncate/fill it to 12 characters as per spec, if needed. Abuild-tested.
