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.

2012-11-28amdk8/amdfam10: Use CAR_GLOBAL for sysinfoPatrick Georgi
This gets rid of the somewhat unstructured placement of AMD's sysinfo structure in CAR. We used to carve out some CAR space using a Kconfig variable, and then put sysinfo there manually (by "virtue" of pointer magic). Now it's a variable with the CAR_GLOBAL qualifier, and build system magic. For this, the following steps were done (but must happen together since the intermediates won't build): - Add new CAR_GLOBAL sysinfo_car - point all sysinfo pointers to sysinfo_car instead of GLOBAL_VAR - remove DCACHE_RAM_GLOBAL_VAR_SIZE - from CAR setup (no need to reserve the space) - commented out code (that was commented out for years) - only copy sizeof(sysinfo) into RAM after ram init, where before it copied the whole GLOBAL_VAR area. - from Kconfig Change-Id: I3cbcccd883ca6751326c8e32afde2eb0c91229ed Signed-off-by: Patrick Georgi <patrick@georgi-clan.de> Reviewed-on: http://review.coreboot.org/1887 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org> Reviewed-by: Marc Jones <marcj303@gmail.com>

After collecting dependencies for ramstage, add an intermediate step in which object files are linked per directory. The results are then linked into the final binary.

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.

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.

2012-11-23libpayload: Detach devices behind removed USB hubsNico Huber
When a USB hub got removed, we should also remove all devices that were attached to it.

2012-11-23libpayload: More compliant error recovery in USB MSCNico Huber
If an endpoint gets stalled by an MSC device, after successful transmission of a command (CBW), we should still ask for the status (CSW). Otherwise, the driver and the device get desynchronized on the command tags.

Stalled transfers are not fatal, so don't spew on the console on every tiny failure.

2012-11-23libpayload: Fix random warningsNico Huber
dump_td() is orphaned but looks useful => commented out. The delay identifier shadowed the global one => renamed to total_delay.

2012-11-23libpayload: ehci: Fix warnings about discarded volatileNico Huber
We can trust free() and memset() to work correctly on volatile references, so cast volatile pointers to (void *) when calling them.

2012-11-23libpayload: Fix some missing-prototype warningsNico Huber
usb_controller_initialize() is not declared in any header file nor called from outside of usbinit.c, so make it static. set_configuration() looks like beeing non-static on purpose (like the other helpers around it in usb.c), so put a prototype into usb.h.

2012-11-23libpayload: Fix memalign() for fragmented alignment regionsNico Huber
Found a bug in the memory allocator ;-) If the total free space in an alignment region is large enough for an allocation but fragmented, such that there is no contiguous, sufficient large, free space in the region, memalign() was looking at the same region again and again in an endless loop. The advancing to the next region was just missing.
