 /* My understanding of UniNorth AGP as of UniNorth rev 1.0x,

  *
  * AGP_BASE register contains the base address of the AGP aperture on
  * the AGP bus. It doesn't seem to be visible to the CPU as of UniNorth 1.x,
  * even if decoding of this address range is enabled in the address select
  * register. Apparently, the only supported bases are 256Mb multiples
  * (high 4 bits of that register).
  *
  * GART_BASE register appear to contain the physical address of the GART
  * in system memory in the high address bits (page aligned), and the
  * GART size in the low order bits (number of GART pages)
  *
  * The GART format itself is one 32bits word per physical memory page.
  * This word contains, in little-endian format (!!!), the physical address
  * of the page in the high bits, and what appears to be an "enable" bit
  * in the LSB bit (0) that must be set to 1 when the entry is valid.
  *
  * Obviously, the GART is not cache coherent and so any change to it
  * must be flushed to memory (or maybe just make the GART space non
  * cachable). AGP memory itself does't seem to be cache coherent neither.
  *
  * In order to invalidate the GART (which is probably necessary to inval
  * the bridge internal TLBs), the following sequence has to be written,
  * in order, to the GART_CTRL register:
  *
  *   UNI_N_CFG_GART_ENABLE | UNI_N_CFG_GART_INVAL
  *   UNI_N_CFG_GART_ENABLE
  *   UNI_N_CFG_GART_ENABLE | UNI_N_CFG_GART_2xRESET
  *   UNI_N_CFG_GART_ENABLE
  *
  * As far as AGP "features" are concerned, it looks like fast write may
  * not be supported but this has to be confirmed.
  *
  * Turning on AGP seem to require a double invalidate operation, one before
  * setting the AGP command register, on after.
  *
  * Turning off AGP seems to require the following sequence: first wait
  * for the AGP to be idle by reading the internal status register, then
  * write in that order to the GART_CTRL register:
  *
  *   UNI_N_CFG_GART_ENABLE | UNI_N_CFG_GART_INVAL
  *   0
  *   UNI_N_CFG_GART_2xRESET
  *   0
