2014-08-28libpayload: Change CONFIG_X86_SERIAL_CONSOLE to CONFIG_8250_SERIAL_CONSOLEGabe Black
While the 8250 compatible serial port driver is primarily useful on x86 systems because it works with the legacy x86 com ports, some devices which aren't x86 based have 8250 compatible UARTs as well. This change renames the CONFIG_X86_SERIAL_CONSOLE option to the more general and direct CONFIG_8250_SERIAL_CONSOLE and fixes up the dependencies so that non-x86 systems can enable the driver, although it will default to on on x86 and off otherwise. Also, the default IO port address that's added to the sysinfo structure on x86 and which is intended to be overwritten by a value in the coreboot tables is not used on ARM. That variable is adjusted so that it's more clear it's a default value, and made dependent on x86 since that's the only place its value is actually used.

2014-08-18libpayload: usbmsc: Remove DETACHED state from MSC device structureJulius Werner
The USB MSC device structure contains a "ready" state that can be either "ready", "not ready" or "detached". The last one can only be assigned when the device is completely unresponsive and gets forcefully logically detached via usb_detach_device(). This call (at least in the current version) also calls all destructors and frees the complete usbdev_t structure (including the MSC specific part), which unfortunately makes storing the "detached" state in that very structure a little pointless. This patch reduces the "ready" value to a simple boolean and makes sure that all detachment cases immediately return from the MSC driver, carefully avoiding any use-after-free opportunities.

2014-08-14libpayload: dma_malloc: Prevent warm reboot problems and add debuggingJulius Werner
Since the DMA memory is allocated by Coreboot (outside of the payload's linker script), it won't get zeroed upon loading like the heap. Therefore, a warm reboot that doesn't reset memory may leave stale malloc cookies lying around and misinterpret them as memory that is still in use on the next boot. After several boots this may fill up the whole DMA memory and lead to OOM conditions. Therefore, this patch explicitly wipes the first cookie in init_dma_memory() to prevent that from happening. It also expands the existing memory allocator debugging code to cover the DMA parts, which was very helpful in identifying this particular problem.

2014-08-14libpayload: xhci: Make XHCI stack usable on ARMJulius Werner
This patch updates the libpayload XHCI stack to run on ARM CPUs (tested with the DWC3 controller on an Exynos5420). Firstly, it adds support for 64-byte Slot/Endpoint Context sizes. Since the existing context handling code represented the whole device context as a C struct (whose size has to be known at compile time), it was necessary to refactor the input and device context structures to consist of pointers to the actual contexts instead. Secondly, it moves all data structures that the xHC accesses through DMA to cache-coherent memory. With a similar rationale as in the ARM patches for EHCI, using explicit cache maintenance functions to correctly handle the actual transfer buffers in all cases is presumably impossible. Instead this patch also chooses to create a DMA bounce buffer in the XHCI stack where transfer buffers which are not already cache-coherent will be copied to/from.

2014-08-14libpayload: Make EHCI driver cache-awareJulius Werner
This patch makes the EHCI driver work on ARM platforms which usually do not support automatic cache snooping. It uses the new DMA memory mechanism (which needs to be correctly set up in the Coreboot mainboard code) to allocate all EHCI-internal communication structures in cache-coherent memory, and cleans/invalidates the externally supplied transfer buffers in Bulk and Control functions with explicit calls as necessary.

It turns out that my previous commit to make the EHCI stack cache aware on ARM devices wasn't quite correct, and the problem is actually much trickier than I thought. After having some fun with more weird transfer problems that appear/disappear based on stack alignment, this is my current worst-case threat model that any cache managing implementation would need to handle correctly: Some upper layer calls ehci_bulk() with a transfer buffer on its stack. Due to stack alignment, it happens to start just at the top of a cache line, so up to 64 - 4 bytes of ehci_bulk's stack will share that line. ehci_bulk() calls dcache_clean() and initializes the USB transfer. Between that point and the call to dcache_invalidate() at the end of ehci_bulk(), any access to the stack variables in that cache line (even a speculative prefetch) will refetch the line into the cache. Afterwards any other access to a random memory location that just happens to get aliased to the same cache line may evict it again, causing the processor to write out stale data to the transfer buffer and possibly overwrite data that has already been received over USB. In short, any dcache_clean/dcache_invalidate-based implementation that preserves correctness while allowing any arbitrary (non cache-aligned) memory location as a transfer buffer is presumed to be impossible. Instead, this patch causes all transfer data to be copied to/from a cache-coherent bounce buffer. It will still transfer directly if the supplied buffer is already cache-coherent, which can be used by callers to optimize their transfers (and is true by default on x86).

2014-08-13arm: libpayload: Add cache coherent DMA memory definition and managementJulius Werner
This patch adds a mechanism to set aside a region of cache-coherent (i.e. usually uncached) virtual memory, which can be used to communicate with DMA devices without automatic cache snooping (common on ARM) without the need of explicit flush/invalidation instructions in the driver code. This works by setting aside said region in the (board-specific) page table setup, as exemplary done in this patch for the Snow and Pit boards. It uses a new mechanism for adding board-specific Coreboot table entries to describe this region in an entry with the LB_DMA tag. Libpayload's memory allocator is enhanced to be able to operate on distinct types/regions of memory. It provides dma_malloc() and dma_memalign() functions for use in drivers, which by default just operate on the same heap as their traditional counterparts. However, if the Coreboot table parsing code finds a CB_DMA section, further requests through the dma_xxx() functions will return memory from the region described therein instead.

2014-08-12libpayload: Make USB transfer functions return amount of bytesJulius Werner
The USB bulk and control transfer functions in libpayload currently always return 0 for success and 1 for all errors. This is sufficient for current use cases (essentially just mass storage), but other classes (like certain Ethernet adapters) need to be able to tell if a transfer reached the intended amount of bytes, or if it fell short. This patch slightly changes that USB API to return -1 on errors, and the amount of transferred bytes on successes. All drivers in the current libpayload mainline are modified to conform to the new error detection model. Any third party users of this API will need to adapt their if (...<controller>->bulk/control(...)) checks to if (...<controller>->bulk/control(...) < 0) as well. The host controller drivers for OHCI and EHCI correctly implement the new behavior. UHCI and the XHCI stub just comply with the new API by returning 0 or -1, but do not actually count the returned bytes.

2014-08-11libpayload: xhci: Use Event Data TRBs for transfer event generationJulius Werner
The current XHCI code only sets IOC on the last TRB of a TD, and doesn't set ISP anywhere. On my Synopsys DesignWare3 controller, this won't generate an event at all when we have a short transfer that is not on the last TRB of a TD, resulting in event ring desync and everyone having a bad time. However, just setting ISP on other TRBs doesn't really make for a nice solution: we then need to do ugly special casing to fish out the spurious second transfer event you get for short packets, and we still need a way to figure out how many bytes were transferred. Since the Short Packet transfer event only reports untransferred bytes for the current TRB, we would have to manually walk the rest of the unprocessed TRB chain and add up the bytes. Check out U-Boot and the Linux kernel to see how complicated this looks in practice. Now what if we had a way to just tell the HC "I want an event at exactly *this* point in the TD, I want it to have the right completion code for the whole TD, and to contain the exact number of bytes written"? Enter the Event Data TRB: this little gizmo really does pretty much exactly what any sane XHCI driver would want, and I have no idea why it isn't used more often. It solves both the short packet event generation and counting the transferred bytes without requiring any special magic in software.

2014-08-10armv7: Support stack dump after exceptionsJulius Werner
This patch enhances the armv7 exception handlers in Coreboot and libpayload to show the correct SP and LR registers from the aborted context, and also dump a part of the current stack. Since we cannot access the banked registers of SVC mode from a different exception mode, it changes Coreboot (and its payloads) to run in System mode instead. As both modes can execute all privileged instructions, this should not have any noticeable effect on firmware operation (please correct me if I'm wrong!).

When libpayload header files are included in the payload itself, it's possible that the payloads config settings will conflict with the ones in libpayload. It's also possible for the libpayload config settings to conflict with the payloads. To avoid that, the libpayload config settings have _LP_ (for libpayload) added to them. The symbols themselves as defined in the Config.in files are still the same, but the prefix added to them is now CONFIG_LP_ instead of just CONFIG_.
