[IA64] Move include/asm-ia64 to arch/ia64/include/asm
After moving the the include files there were a few clean-ups:
1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h>
2) Some comments alerted maintainers to look at various header files to
make matching updates if certain code were to be changed. Updated these
comments to use the new include paths.
3) Some header files mentioned their own names in initial comments. Just
deleted these self references.

PCI/X requires that the 'bridge' (i.e. PIC) + * be designated as 'device 0'. That is a departure from earlier SGI + * PCI bridges. Because of that we use config space 1 to access the + * config space of the first actual PCI device on the bus. + * Here's what the PIC manual says: + * + * The current PCI-X bus specification now defines that the parent + * hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC + * reduced the total number of devices from 8 to 4 and removed the + * device registers and windows, now only supporting devices 0,1,2, and + * 3. PIC did leave all 8 configuration space windows. The reason was + * there was nothing to gain by removing them. Here in lies the problem. + * The device numbering we do using 0 through 3 is unrelated to the device + * numbering which PCI-X requires in configuration space. In the past we + * correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc. + * PCI-X requires we start a 1, not 0 and currently the PX brick + * does associate our: + * + * device 0 with configuration space window 1, + * device 1 with configuration space window 2, + * device 2 with configuration space window 3, + * device 3 with configuration space window 4. + * + * The net effect is that all config space access are off-by-one with + * relation to other per-slot accesses on the PIC. + * Here is a table that shows some of that: + * + * Internal Slot# + * | + * | 0 1 2 3 + * ----------|--------------------------------------- + * config | 0x21000 0x22000 0x23000 0x24000 + * | + * even rrb | 0[0] n/a 1[0] n/a [] == implied even/odd + * | + * odd rrb | n/a 0[1] n/a 1[1] + * | + * int dev | 00 01 10 11 + * | + * ext slot# | 1 2 3 4 + * ----------|--------------------------------------- + */ + +#define PIC_ATE_TARGETID_SHFT 8 +#define PIC_HOST_INTR_ADDR 0x0000FFFFFFFFFFFFUL +#define PIC_PCI64_ATTR_TARG_SHFT 60 + + +/***************************************************************************** + *********************** PIC MMR structure mapping *************************** + *****************************************************************************/ + +/* NOTE: PIC WAR.

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.

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.
