2013-11-08Add new finalize functions for devices and chipsMarc Jones
Many chipset devices require additional configuration after device init. It is not uncommmon for a device early in the devicetree list to need to change a setting after a device later in the tree does PCI init. A final function call has been added to device ops to handle this case. It is called prior to coreboot table setup. Another problem that is often seen is that the chipset or mainboard need to do some final cleanup just before loading the OS. The chip finalize has been added for this case. It is call after all coreboot tables are setup and the payload is ready to be called. Similar functionality could be implemented with the hardwaremain states, but those don't fit well in the device tree function pointer structure and should be used sparingly.

The main usbdebug file lib/usbdebug.c was removed from romstage build with commit f8bf5a10 but the chipset-specific parts were not, leading to unresolved symbol errors for AMD platforms.

2013-08-19Don't include LZMA in romstage if ramstage is not compressed.Andrew Wu
If ramstage is not compressed, the CBFS module in romstage doesn't need to support LZMA. Removing the LZMA module in this case can save about 3000 bytes in romstage.

2013-08-15CBFS: Change how the bss is zeroed when loading a stage.Gabe Black
For reasons explained in a previous CL, it might be necessary to "load" a file from CBFS in place. The loading code in CBFS was, however, zeroing the area of memory the stage was about to be loaded into. When the CBFS data is located elsewhere this works fine, but when it isn't you end up clobbering the data you're trying to load. Also, there's no reason to zero memory we're about to load something into or have just loaded something into. This change makes it so that we only zero out the portion of the memory between what was loaded/decompressed and the final size of the stage in memory.

2013-08-15CBFS: Change the signature of cbfs_decompress.Gabe Black
Instead of returning 0 on success and -1 on error, return the decompressed size of the data on success and 0 on error. The decompressed size is useful information to have that was being thrown away in that function.

2013-08-10usbdebug: Add option for verbose logging of connectionKyösti Mälkki
Add option to log changes in USB 2.0 EHCI debug port connection. For romstage move usbdebug as the last initialised console so one actually can see these messages. Init order of consoles in ramstage is undetermined and unchanged.

2013-08-01Add directive __SIMPLE_DEVICE__Kyösti Mälkki
The tests for __PRE_RAM__ or __SMM__ were repeatedly used for detection if dev->ops in the devicetree are not available and simple device model functions need be used. If a source file build for ramstage had __PRE_RAM__ inserted at the beginning, the struct device would no longer match the allocation the object had taken. This problem is fixed by replacing such cases with explicit __SIMPLE_DEVICE__.

2013-07-15CBFS: Use memmove instead of memcpy when loading a file from CBFS.Gabe Black
It might be the case that a file is being loaded from a portion of CBFS which has already been loaded into a limitted bit of memory somewhere, and we want to load that file in place, effectively, so that it's original location in CBFS overlaps with its new location. That's only guaranteed to work if you use memmove instead of memcpy.
