2014-09-25libpayload: Add missing cache API stub to x86Julius Werner
This patch adds another cache invalidation stub to the x86 arch to make it usable in common code. This whole stuff should probably be redesigned anyway but I just want to get it working and unblock my CL for now... more cleanups coming later.

2014-09-22arm: Update mem* functions to newer versionsJulius Werner
The memcpy/memset/memmove assembly implementations have been taken from U-Boot, which originally got them from Linux. I turns out that they are actually not that bad, but they could use an update. This patch pulls in the current Linux upstream versions of those files, removing some old U-Boot cruft such as checking whether the two pointers in a memcpy() are equal (really now?) or side-stepping the R8 register because it was used for special purposes. It also returns to the good old Linux ENTRY/ENDPROC macros since we have them now anyway, and straightens out the W() macro in preparation for unified thumb support.

2014-09-22arm: Move libgcc assembly macros to arch/asm.hJulius Werner
libgcc/macros.h contains some useful assembly macros that are common in Linux kernel code and facilitate things such as unified ARM/THUMB assembly. This patch moves it to a more general place where it can be used by other code as well.

2014-09-15libpayload: Add a new "die" function to fatally signal programming errors.Gabe Black
If a programming error is detected, die can be used to print a message and stop execution similar to failing an assert. There's also a "die_if" function which is conditional. die functions, like asserts, should be used to trap programming errors and not when the hardware does something wrong. If all code was written perfectly, no die function would ever be called. In other words, it would be appropriate to use die if a function was called with a value that was out of bounds or if malloc failed. It wouldn't be appropriate if an external device doesn't respond. In the future, the die family of functions might print a stack trace or show other debugging info.

2014-09-08ARM: Generalize armv7 as arm.Gabe Black
There are ARM systems which are essentially heterogeneous multicores where some cores implement a different ARM architecture version than other cores. A specific example is the tegra124 which boots on an ARMv4 coprocessor while most code, including most of the firmware, runs on the main ARMv7 core. To support SOCs like this, the plan is to generalize the ARM architecture so that all versions are available, and an SOC/CPU can then select what architecture variant should be used for each component of the firmware; bootblock, romstage, and ramstage.

2014-09-04libpayload: usb: Refactor USB enumeration to fix SuperSpeed devicesJulius Werner
This patch represents a major overhaul of the USB enumeration code in order to make it cleaner and much more robust to weird or malicious devices. The main improvement is that it correctly parses the USB descriptors even if there are unknown descriptors interspersed within, which is perfectly legal and in particular present on all SuperSpeed devices (due to the SuperSpeed Endpoint Companion Descriptor). In addition, it gets rid of the really whacky and special cased get_descriptor() function, which would read every descriptor twice whether it made sense or not. The new code makes the callers allocate descriptor memory and only read stuff twice when it's really necessary (i.e. the device and configuration descriptors). Finally, it also moves some more responsibilities into the controller-specific set_address() function in order to make sure things are initialized at the same stage for all controllers. In the new model it initializes the device entry (which zeroes the endpoint array), sets up endpoint 0 (including MPS), sets the device address and finally returns the whole usbdev_t structure with that address correctly set. Note that this should make SuperSpeed devices work, but SuperSpeed hubs are a wholly different story and would require a custom hub driver (since the hub descriptor and port status formats are different for USB 3.0 ports, and the whole issue about the same hub showing up as two different devices on two different ports might present additional challenges). The stack currently just issues a warning and refuses to initialize this part of the hub, which means that 3.0 devices connected through a 3.0 hub may not work correctly.

This patch removes the confusing concept of a special "xhci_speed" with a different numeric value from the usual speed used throughout the USB core (except for the places directly interacting with the xHC, which are explicitly marked). It also moves the MPS0 decoding function into the core and moves some definitions around in preparation of later changes that will make the stack SuperSpeed-ready. It makes both set_address implementations share a constant for the specification-defined SetAddress() recovery delay and removes pointless additional delays from the non-XHCI version.

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: 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. Old-Change-Id: Ie8a62545d905b7a4fdd2a56b9405774be69779e5 Signed-off-by: Julius Werner <jwerner@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/167339 (cherry picked from commit 322338934add36a5372ffe7d2a45e61a4fdd4a54) libpayload: ehci: Cache management is hard, let's go copying... 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.

Mass storage devices such as card readers show up as as USB devices. However the media not be inserted. In those situations the previous code would just fake a disk and call usbcreate_disk. This is inappropriate because it forms a 1:1 mapping of USB device to disk leading to the inability to remove the disk and/or handle "hot plug" card insertion and removals. To alleviate this issue introduce the notion of ready to the usbmsc structure. It tracks detached, not ready, and ready states. The polling routine is then used to track not ready to ready transitions thereby creating and removing disks appropriately. This handles the case of inserting and removing a card that shows up as a new disk. Booted recovery mode. Able to observe inerstion and removal of sdcard. Also able to insert valid USB flash drive to boot as well.

xHCI requires special treatment of set_address since it determines the device number itself (instead of the driver, as with the other controllers). The controller also wants to validate a chosen device configuration and we need to setup additional structures for the device and the endpoints. Therefore, we add three functions to the hci_t structure, namely: set_address() finish_device_config() destroy_device() Current implementation for the Set Address request moved into generic_set_address() which is set_address() for the UHCI, OCHI and EHCI drivers. The latter two are only provided as hooks for the xHCI driver. The Set Configuration request is moved after endpoint enumeration. For all other controller drivers nothing changes, as there is no other device communication between the lines where the set_configuration() call moved.

It might be useful to provide a USB driver in the payload itself instead of in libpayload. For example there are multiple payloads being built and linked against the same libpayload, and they might not need or even want to have the same set of drivers installed.

If a USB device isn't recognized and claimed by one of the built in USB class drivers (currently hub, hid, and msc) and the create function is defined, then it will be called to give the payload a chance to use the device. Once it's removed, if usb_generic_remove is defined it will be called, effectively giving the payload notice. Built and booted depthcharge on Link. Built depthcharge for Daisy. Built a netbooting payload, called usb_poll() with those functions implemented, and verified that they were called and that the devices they were told about were reasonable and the same as what was reported by lsusb in the booted system.

2013-02-12libpayload: New CBFS to support multiple firmware media sources.Hung-Te Lin
Upgrade CBFS in libpayload to use new media-based implementation from coreboot ( http://review.coreboot.org/#/c/2182/ ). Old CBFS functions (cbfs_find, cbfs_find_file, get_cbfs_header) are still supported, although the recommended way is to use new CBFS API. To migrate your existing x86 payload source: - Change cbfs_find to cbfs_get_file - Change cbfs_find_file to cbfs_get_file_content - Prefix every CBFS call with a CBFS_DEFAULT_MEDIA argument. Ex, char *jpeg_data = cbfs_find_file("splash.jpg", CBFS_TYPE_BOOTSPLASH); => char *jpeg_data = cbfs_get_file_content( CBFS_DEFAULT_MEDIA, "splash.jpg", CBFS_TYPE_BOOTSPLASH); The legacy setup_cbfs_from_{ram,flash} is also supported, although the better equivalent is to make a new media instance: struct cbfs_media ram_media; init_cbfs_ram_media(&ram_media, start, size); char *data = cbfs_get_file_content(&ram_media, "myfile", my_type); Verified by being successfully linked with filo.

Warning: This breaks code that relies on the current, special, counterintuitive behaviour of uhci_reset().
