2012-11-24libpayload: Fix interrupt-queue cleanup for OHCINico Huber
We have to free TDs more carefully if they have been processed by the controller yet. The current code tries to force the controller to post them back to the done queue, but that seems wrong. We can't be sure, when they get written back. This resulted in leaking TDs with an invalid reference to a freed interrupt queue. The new approach: Mark the interrupt queue to be destroyed and handle the freeing later, when the controller posted the last TD to the done queue.

2012-11-24libpayload: Implement correct interrupt-queue linking for UHCINico Huber
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.

2012-11-15libpayload: Always use virtual pointers in struct sysinfo_tNico Huber
We had mixed virtual and physical pointers in struct sysinfo_t. Some being virtual by accident which led to problems when we tried to reinitialize lib_sysinfo after relocating FILO (to get intentionally virtual pointers valid again). I guess this didn't cause much trouble before, as lib_get_sysinfo() was always called with physical addresses being equal to their virtual counterparts. For FILO, two possibilities seem practical: Either, have all pointers in struct sysinfo_t physical, so relocation doesn't hurt. Or, have all pointers virtual and call lib_get_sysinfo() again after relocation. This patch goes the latter way, changing the following pointers for situations where virtual pointers differ from physical: .extra_version .build .compile_time .compile_by .compile_host .compile_domain .compiler .linker .assembler .cb_version .vdat_addr .tstamp_table .cbmem_cons .mrc_cache We could also just correct the accidentally virtual pointers. But, IMO, this would lower the risk of future confusion. Note 1: Looks like .version gets never set. Note 2: .option_table and .framebuffer were virtual pointers but treated like physical ones. Even in FILO, this led to no problems as they were set before relocation.

uhci_reset() differs in semantics compared to the other HCI's reset() implementations. uhci_reset() does some initialization work after a controller reset. So move the initialization part to a new function, uhci_reinit(), which get's exported through a new entry in hci_t: hci_t.init(). Warning: This breaks code that relies on the current, special, counterintuitive behaviour of uhci_reset(). If one wants a working host controller after calling hci_t.reset(), he should call hci_t.init() afterwards.

2012-10-27libpayload: New AHCI, ATA and ATAPI driversNico Huber
This adds a new interface for storage devices. A driver for ATA and ATAPI drives on AHCI host controllers comes along. The interface is very simple and was designed to match FILO's needs. It consists of three functions: void storage_initialize(void); Initializes controllers. Should be called once at startup. storage_poll_t storage_probe(size_t dev_num); with typedef enum { POLL_NO_DEVICE = -2, POLL_ERROR = -1, POLL_NO_MEDIUM = 0, POLL_MEDIUM_PRESENT = 1, } storage_poll_t; Looks for a drive with number dev_num (drives are counted from zero) and polls for a medium in the drive if appropriate. int storage_read_blocks512(size_t dev_num, u64 start, size_t count, unsigned char *buf); Reads count blocks of 512 bytes from block start of drive dev_num into buf.

Instead of having the highlevel functions make use of the lowlevel functions, it implemented the lowlevel stuff in terms of highlevel.

This enables building with dash again(?) by using exactly one patch of SeaBIOS more/newer than previously, which has also the sole purpose of removing bashism and is a single line change. *sigh* Change-Id: Ib036894d8b9886f74d6eb0853f1fc0ce1aa39d54 Signed-off-by: Stefan Tauner <stefan.tauner@gmx.at> Reviewed-on: http://review.coreboot.org/1568 Reviewed-by: Peter Stuge <peter@stuge.se> Tested-by: build bot (Jenkins)
