- * Mask/shift definitions for TIO:CA registers. The convention here is
- * to mainly use the names as they appear in the "TIO AEGIS Programmers'
- * Reference" with a CA_ prefix added. Some exceptions were made to fix
- * duplicate field names or to generalize fields that are common to
- * different registers (ca_debug_mux_core_sel and ca_debug_mux_pci_sel for
- * example).
- *
- * Fields consisting of a single bit have a single #define have a single
- * macro declaration to mask the bit. Fields consisting of multiple bits
- * have two declarations: one to mask the proper bits in a register, and
- * a second with the suffix "_SHFT" to identify how far the mask needs to
- * be shifted right to get its base value.

- * DMA space
- *
- * The CA aperature (ie. bus address range) mapped by the GART is segmented into
- * two parts. The lower portion of the aperature is used for mapping 32 bit
- * PCI addresses which are managed by the dma interfaces in this file. The
- * upper poprtion of the aperature is used for mapping 48 bit AGP addresses.
- * The AGP portion of the aperature is managed by the agpgart_be.c driver
- * in drivers/linux/agp. There are ca-specific hooks in that driver to
- * manipulate the gart, but management of the AGP portion of the aperature
- * is the responsibility of that driver.
- *
- * CA allows three main types of DMA mapping:
- *
- * PCI 64-bit Managed by this driver
- * PCI 32-bit Managed by this driver
- * AGP 48-bit Managed by hooks in the /dev/agpgart driver
- *
- * All of the above can optionally be remapped through the GART. The following
- * table lists the combinations of addressing types and GART remapping that
- * is currently supported by the driver (h/w supports all, s/w limits this):
- *
- * PCI64 PCI32 AGP48
- * GART no yes yes
- * Direct yes yes no
- *
- * GART remapping of PCI64 is not done because there is no need to. The
- * 64 bit PCI address holds all of the information necessary to target any
- * memory in the system.
- *
- * AGP48 is always mapped through the GART. Management of the AGP48 portion
- * of the aperature is the responsibility of code in the agpgart_be driver.
- *
- * The non-64 bit bus address space will currently be partitioned like this:
- *
- * 0xffff_ffff_ffff +--------
- * | AGP48 direct
- * | Space managed by this driver
- * CA_AGP_DIRECT_BASE +--------
- * | AGP GART mapped (gfx aperature)
- * | Space managed by /dev/agpgart driver
- * | This range is exposed to the agpgart
- * | driver as the "graphics aperature"
- * CA_AGP_MAPPED_BASE +-----
- * | PCI GART mapped
- * | Space managed by this driver
- * CA_PCI32_MAPPED_BASE +----
- * | PCI32 direct
- * | Space managed by this driver
- * 0xC000_0000 +--------
- * (CA_PCI32_DIRECT_BASE)
- *
- * The bus address range CA_PCI32_MAPPED_BASE through CA_AGP_DIRECT_BASE
- * is what we call the CA aperature. Addresses falling in this range will
- * be remapped using the GART.
- *
- * The bus address range CA_AGP_MAPPED_BASE through CA_AGP_DIRECT_BASE
- * is what we call the graphics aperature. This is a subset of the CA
- * aperature and is under the control of the agpgart_be driver.
- *
- * CA_PCI32_MAPPED_BASE, CA_AGP_MAPPED_BASE, and CA_AGP_DIRECT_BASE are
- * somewhat arbitrary values. The known constraints on choosing these is:
- *
- * 1) CA_AGP_DIRECT_BASE-CA_PCI32_MAPPED_BASE+1 (the CA aperature size)
- * must be one of the values supported by the ca_gart_aperature register.
- * Currently valid values are: 4MB through 4096MB in powers of 2 increments
- *
- * 2) CA_AGP_DIRECT_BASE-CA_AGP_MAPPED_BASE+1 (the gfx aperature size)
- * must be in MB units since that's what the agpgart driver assumes.
- */
-
-/*
- * Define Bus DMA ranges. These are configurable (see constraints above)
- * and will probably need tuning based on experience.

-/*
- * 11/24/03
- * CA has an addressing glitch w.r.t. PCI direct 32 bit DMA that makes it
- * generally unusable. The problem is that for PCI direct 32
- * DMA's, all 32 bits of the bus address are used to form the lower 32 bits
- * of the coretalk address, and coretalk bits 38:32 come from a register.
- * Since only PCI bus addresses 0xC0000000-0xFFFFFFFF (1GB) are available
- * for DMA (the rest is allocated to PIO), host node addresses need to be
- * such that their lower 32 bits fall in the 0xC0000000-0xffffffff range
- * as well. So there can be no PCI32 direct DMA below 3GB!! For this
- * reason we set the CA_PCI32_DIRECT_SIZE to 0 which essentially makes
- * tioca_dma_direct32() a noop but preserves the code flow should this issue
- * be fixed in a respin.
- *
- * For now, all PCI32 DMA's must be mapped through the GART.
