* Major endianness fixes on sky code today. The milestone sample and existing
PKE tests run identically on SPARC/Solaris and x86/Linux. * sky-pke.c (pke_io_{read,write}_buffer): Endianness fixes aka "E-fixes" in register and FIFO read/writes. (pke_code_{pkemscalf,pkemscal}): E-fixes in VU CIA setting. (pke_code_{mpg,unpack}): E-fixes in VU memory & tracking updates. (pke_code_direct): E-fixes in GPUIF FIFO stuffing. * sky-pke.h (PKE_MEM_WRITE): E-fixes in trace file writing. * sky-vu0.c (vu0_attach): Allocate micro/data memory with zalloc to guarantee sufficient (16-byte) alignment. * sky-vu1.c (vu1_attach): Ditto. (vu1_io_read_register_window): *PARTIAL* E-fixes in register accesses. * sky-libvpe.c (gif_write): E-fixes in GPUIF FIFO stuffing. * sky-gpuif.c (gif_io_{read,write}_buffer): E-fixes in register and FIFO read/writes. * sky-dma.c (do_dma_transfer_tag): E-fixes in tag reading.
