| H A D | ehcireg.h | diff 214349 Mon Oct 25 16:03:12 MDT 2010 nwhitehorn The EHCI_CAPLENGTH and EHCI_HCIVERSION registers are actually sub-registers within the first 4 bytes of the EHCI memory space. For controllers that use big-endian MMIO, reading them with 1- and 2-byte reads would then return the wrong values. Instead, read the combined register with a 4-byte read and mask out the interesting quantities. |
