2015-04-09libpayload: PCI bus scan - Eliminate endless loopLee Leahy
Don't attempt to scan the PCI bus if the bridge is disabled. When the PCI bridge is not setup and enabled, it is possible for the secondary bus register to contain the value zero (0). In this case the usb_scan_pci_bus routine gets into an infinite recursive loop which ends only when the heap or stack is exhausted. This patch verifies that the PCI bridge is enabled by verifying that it is enabled for either memory or I/O operations. When enabled, the secondary bus is scanned.

2015-04-08arm: Dump additional fault registers in abort handlersJulius Werner
Paging code is tricky and figuring out what is wrong with it can be a pain. This patch tries to ease the burden by giving a little more information for prefetch and data aborts, dumping the Instruction Fault Address Register (IFAR), Instruction Fault Status Register (IFSR) and Auxiliary Instruction Fault Status Register (AIFSR) or the respective Data registers. These contain additional information about the cause of the abort (internal/external, write or read, fault subtype, etc.) and the faulting address. BUG=None TEST=I have read through enough imprecise asynchronous external abort reports with this patch that I learned the bit pattern by heart.

2015-03-23libpayload: usb: xhci: set ENT flag in last Normal TRBSourabh Banerjee
If a TD is comprised of one or more Normal TRBs and terminated with an Event Data TRB, then the transition to the Idle state (and associated Stream state save) could occur after all the data for the TD has been moved (e.g. after Transfer Event TRBs have been executed), but before the Event Data TRB is executed. Under these conditions, the execution of the Event Data TRB is necessary to complete the TD, otherwise it does not occur until the next time the Stream is scheduled. This could lead to the lock up. The Evaluate Next TRB(ENT) flag provides a means of forcing the execution of a terminating Event Data TRB. Setting ENT flag in last Normal TRB makes the xHC to evaluate the Even Data TRB.

What this change does: 1) Initialize limited page tables as soon as we jump into libpayload. Basically two ranges are initialized. One is for the BASE_ADDRESS and other is for the coreboot_tables. With page tables initialized and MMU enabled, we jump into code to parse coreboot tables. 2) Once coreboot tables are parsed and we have complete picture of the memory, we perform a complete page table initialzation and enable MMU and then jump to payload. Additionally, we also: 1) Initialize DMA memory on our own depending upon the memory map. It ensures that the DMA buffer is placed in 32-bit memory.

2015-03-20libpayload: Consolidate coreboot table parsingVadim Bendebury
There are three instances of coreboot.c in libpayload. for x86, arm and arm64 architectures. The arm and arm64 instances are exactly the same. The differences with the x86 instance are as follows: - a very slightly different set of coreboot table tags is parsed (one tag added and two removed) - instead of checking a fixed address if it contains the coreboot table, the x86 version iterates over two address ranges. This patch refactors the module, leaving architecture specific processing in arch subdirectories and moving the common code into libc.

As opposed to other architectures, on MIPS gcc toolchain provided gcclib is not always adequate, for instance when the library does not account for the case when data segment is too large to fit into the 64K GOT. Let's make sure the library is not included when building for MIPS targets.

2015-03-20libpayload: special case large memalign() requestsAaron Durbin
For memalign() requests the current allocator keeps metadata about each chunk of aligned memory that copmrises the size requested. For large allocations relative to the alignment this can cause significant metadata overhead. Instead, consider all memalign() requests whose size meets or exceeds 1KiB or alignment that meets or exceeds 1KiB large requests. These requests are handled specially to only allocate the amount of memory required for the size and alignment constraints by not allocating any metadata as the whole region would be consumed by the request. BUG=None BRANCH=None TEST=Built and tested various scenarios. Noted the ability to free() and properly coalesce the heap as expected.

Some USB sticks seem to send a NAK at a place where they mustn't by spec, leading to a controller side error condition. To avoid it, wait a millisecond which is enough to get past the NAK condition. That delay only happens on device discovery so it won't affect boot time by more than 1ms per device.
