while others dislike them being extra commits, let's clean them up once and for all for the existing code. If it's ugly, let it only be ugly once :-) Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5507 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
2008-09-02This patch adds USB capabilities to libpayload. It requires somePatrick Georgi
memalign implementation (eg. the one I sent yesterday). Features: - UHCI controller driver - UHCI root hub driver - USB MSC (Mass Storage Class) driver - skeleton of a USB HID driver (requires better interrupt transfer handling, which is TODO) - skeleton of a USB hub driver (needs several blank spots filled in, eg. power management. Again: TODO) OHCI and EHCI are not supported, though OHCI support should be rather easy as the stack provides reasonable abstractions (or so I hope). EHCI will probably be more complicated. Isochronous transfers (eg. webcams, audio stuff, ...) are not supported. They can be, but I doubt we'll have a reason for that in the boot environment. The MSC driver was tested against a couple of USB flash drives, and should be reasonably tolerant by now. But I probably underestimate the amount of bugs present in USB flash drives, so feedback is welcome.
