3  * arch/parisc/kernel/firmware.c  - safe PDC access routines
5  *	PDC == Processor Dependent Code
7  * See PDC documentation at
20  *	guidelines when writing PDC wrappers:
22  *	 - the name of the pdc wrapper should match one of the macros
25  *	 - use the static PDC result buffers and "copyout" to structs
27  *	 - hold pdc_lock while in PDC or using static result buffers
30  *	 - the name of the struct used for pdc return values should equal
32  *	   corresponding PDC call
64 #include <asm/pdc.h>
96  * We now detect 32-bit-only PDC and dynamically switch to 32-bit mode
115  * f_extend - Convert PDC addresses to kernel addresses.
116  * @address: Address returned from PDC.
118  * This function is used to convert PDC addresses into kernel addresses
119  * when the PDC address size and kernel address size are different.
137  * @addr: The return buffer from PDC.
139  * This function is used to convert the return buffer addresses retrieved from PDC
140  * into kernel addresses when the PDC address size and kernel address size are
203  * pdc_emergency_unlock - Unlock the linux pdc lock
205  * This call unlocks the linux pdc lock in case we need some PDC functions
220  * This PDC call attempts to read from the specified address and verifies
284  * pdc_pat_chassis_send_log - Sends a PDC PAT CHASSIS log message.
335  * pdc_cpu_rendezvous_lock - Lock PDC while transitioning to rendezvous state
343  * pdc_cpu_rendezvous_unlock - Unlock PDC after reaching rendezvous state
351  * pdc_pat_get_PDC_entrypoint - Get PDC entry point for current CPU
352  * @pdc_entry: pointer to where the PDC entry point should be stored
407  * This PDC call returns the presence and status of all the coprocessors
430  * This PDC call reads from the IODC of the module specified by the hpa
529  * Get system model name from PDC ROM (e.g. 9000/715 or 9000/778/B160L).
809  * This PDC call reads from the Stable Storage address supplied in staddr
835  * This PDC call reads count bytes from the supplied memaddr address,
859  * This PDC call returns the number of bytes in the processor's Stable
881  * This PDC call is meant to be used to check the integrity of the current
901  * This PDC call will erase all contents of Stable Storage. Use with care!
921  * Get the SCSI operational parameters from PDC.

987  * This PDC function returns the number of entries in the specified cell's
1036  * @hpa: Token from PDC to indicate which PCI device
1059  * @hpa: Token from PDC to indicate which PCI device
1213 /* FIXME: Is this pdc used?  I could not find type reference to ftc_bitmap
1276  * This PDC function places the soft power button under software or
1330  * If PDC used the usb controller, the usb controller
1332  * setup, because of still running DMA. This PDC call
1395  * pdc_iodc_getc - Read a character (non-blocking) from the PDC console.
1397  * Read a character (non-blocking) from the PDC console, returns -1 if
1456  * This PDC call returns the cell number of the cell from which the call
1480  * This PDC call returns information about each module attached to the cell
1509  * This PDC call returns information about the given cell (or all cells).
1558  * This PDC function returns the number of entries in the specified cell's
1580  * This PDC function returns the actual interrupt table for the specified cell.
1620  * pdc_pat_pd_get_pdc_revisions - Retrieve PDC interface revisions.
1623  * @pdc_cap: The PDC capabilities.
