2012-11-27Get rid of drivers classPatrick Georgi
The use of ramstage.a required the build system to handle some object files in a special way, which were put in the drivers class. These object files didn't provide any symbols that were used directly (but only via linker magic), and so the linker never considered them for inclusion. With ramstage.a gone, we can drop this special class, too.

2012-11-27Drop ramstage.aPatrick Georgi
ramstage.a has two issues: 1. duplicate source filenames don't survive the ar(1) treatment properly (so files aren't considered) 2. ld doesn't resolve symbols if it isn't forced to, in particular no overrides of weak symbols Downside: The resulting binaries get slightly larger. Link time optimizations should fix that, as would tighter rules in the build system (to not compile unused code in the first place).

2012-11-24libpayload: Fix interrupt-queue cleanup for OHCINico Huber
We have to free TDs more carefully if they have been processed by the controller yet. The current code tries to force the controller to post them back to the done queue, but that seems wrong. We can't be sure, when they get written back. This resulted in leaking TDs with an invalid reference to a freed interrupt queue. The new approach: Mark the interrupt queue to be destroyed and handle the freeing later, when the controller posted the last TD to the done queue.

2012-11-24libpayload: Implement correct interrupt-queue linking for UHCINico Huber
The linking of interrupt queues into UHCI controller's framelist (in uhci_create_intr_queue()) was incomplete. The implementation of uhci_destroy_intr_queue() was even worse, looking like it wanted to clean up more than uhci_create_intr_queue() did. This patch follows the simple approach that we used for OHCI and EHCI: Each slot in the framelist holds only one interrupt queue. Therefore, we have to look for free slots each time we want to link an interrupt queue into the framelist. In return, we have a much simpler structured framelist. With this, USB devices using interrupt transfers (e.g. keyboards) can be detached cleanly from UHCI controllers. Also, more than one of such devices can be attached without further risk.

2012-11-15libpayload: Always use virtual pointers in struct sysinfo_tNico Huber
We had mixed virtual and physical pointers in struct sysinfo_t. Some being virtual by accident which led to problems when we tried to reinitialize lib_sysinfo after relocating FILO (to get intentionally virtual pointers valid again). I guess this didn't cause much trouble before, as lib_get_sysinfo() was always called with physical addresses being equal to their virtual counterparts. For FILO, two possibilities seem practical: Either, have all pointers in struct sysinfo_t physical, so relocation doesn't hurt. Or, have all pointers virtual and call lib_get_sysinfo() again after relocation. This patch goes the latter way, changing the following pointers for situations where virtual pointers differ from physical: .extra_version .build .compile_time .compile_by .compile_host .compile_domain .compiler .linker .assembler .cb_version .vdat_addr .tstamp_table .cbmem_cons .mrc_cache We could also just correct the accidentally virtual pointers. But, IMO, this would lower the risk of future confusion. Note 1: Looks like .version gets never set. Note 2: .option_table and .framebuffer were virtual pointers but treated like physical ones. Even in FILO, this led to no problems as they were set before relocation.

So a new CBMEM ID is added to store the 32bit address so it can be found again easily. A new function is defined to save this pointer in CBMEM which needs to be called when the ACPI tables are created in each mainboard when write_acpi_tables() is called.

2012-11-13cros: Inform U-Boot via fake gpio when VGA Option ROM is loadedBill Richardson
This prepares the way for vboot to inform coreboot when it needs the VGA Option ROM loaded. Coreboot can't always know when it's needed (with keyboard-based dev-mode, coreboot can't tell if we're in dev-mode or not). By the time we get to U-Boot, it's too late, so we need two extra bits - one for vboot to tell coreboot to load the Option ROM and another for coreboot to let vboot know it's been done. This change sets up the communication, but doesn't act on it just yet. Even with this CL we always load the VGA Option ROM, so there's nothing to test. There should be no user-visible change.

2012-11-13Export optionrom status on Stumpy/LumpyVadim Bendebury
ChromeOS' top of the tree u-boot expects coreboot to export information about option ROM status (started/not started). Stumpy and Lumpy were left behind and are not exporting this information. This CL fixes the problem.

2012-11-13Clean up stack checking codeStefan Reinauer
Several small improvements of the stack checking code: - move the CPU0 stack check right before jumping to the payload and out of hardwaremain (that file is too crowded anyways) - fix prototype in lib.h - print size of used stack - use checkstack function both on CPU0 and CPU1-x - print amount of stack used per core Signed-off-by: Stefan Reinauer <reinauer@google.com> Test: Boot coreboot on Link, see the following output: ...

2012-11-13Add method for delaying adding of timestampsStefan Reinauer
In hardwaremain() we can't add timestamps before we actually reinitialized the cbmem area. Hence we kept the timestamps in an array and added them later. This is ugly and intrusive and helped hiding a bug that prevented any timestamps to be logged in hardwaremain() when coming out of an S3 resume. The problem is solved by moving the logic to keep a few timestamps around into the timestamp code. This also gets rid of a lot of ugly ifdefs in hardwaremain.c Change-Id: I945fc4c77e990f620c18cbd054ccd87e746706ef Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/1785 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-11-13Pass the CPU index as a parameter to startup.Ronald G. Minnich
This addition is in support of future multicore support in coreboot. It also will allow us to remove some asssembly code. The CPU "index" -- i.e., its order in the sequence in which cores are brought up, NOT its APIC id -- is passed into the secondary start. We modify the function to specify regparm(0). We also take this opportunity to do some cleanup: indexes become unsigned ints, not unsigned longs, for example. Build and boot on a multicore system, with pcserial enabled. Capture the output. Observe that the messages Initializing CPU #0 Initializing CPU #1 Initializing CPU #2 Initializing CPU #3 appear exactly as they do prior to this change.

2012-11-13Support better tracking of AP stack usage.Ronald G. Minnich
This change allows us to figure out how much of the AP stacks we are using, as well as to catch any case of an AP overrunning its stack. Also, the stack is poisoned, which is a good way to catch programming errors -- code should never count on auto variables being zerod. The stack bases are recorded in a new array, stacks. At the end, when all APs are initialized, the stacks are walked and the lowest level of the stack that is reached is printed. Build and boot and look for output like this: CPU1: stack allocated from 00148000 to 00148ff4:\ lowest stack address was 00148c4c CPU2: stack allocated from 00147000 to 00147ff4:\ lowest stack address was 00147c4c CPU3: stack allocated from 00146000 to 00146ff4:\ lowest stack address was 00146c4c Note that we used only about 1K of stack, even though in this case we allocated 4K (and in the main branch, we allocate 32K!)

Right now coreboot's build process produces images that are not booting on actual hardware because they are smaller than the actual flash device and also don't have an IFD nor an ME firmware in them. In order to produce bootable images, you needed a wrapper script / extra step until now. With this change, the resulting coreboot.rom is actually bootable.
