Ralf Brown; registers of the second type must be listed
in the device documentation.
======================================================================
===================== Function 62, subfunction 11 ====================
== Initialize user-accessible MMIO channel ==
======================================================================
Parameters:
* eax = 62 - function
* bl = 11 - subfunction
* cx = PCI-address (bbbbbbbb dddddfff)
Returns:
* eax = -1 - PCI access not granted;
* eax = -2 - no user MMIO access to this PCI address;
* eax = -3 - memory allocation error; otherwise
* eax = available user heap size.
Remarks:
* Low-level PCI access must be allowed (fn21:12)
* PCI-address should correspond the system var [mmio_pci_addr]
======================================================================
===================== Function 62, subfunction 12 ====================
== Request user-accessible MMIO address space ==
======================================================================
Parameters:
* eax = 62 - function
* bl = 12 - subfunction
* bh = BAR number in PCI configuration space
* ecx = MMIO-block size needed (bytes)
* edx = MMIO-offset (number of whole 4Kb-pages!)
Returns:
* eax = -1 - user PCI access denied;
* eax = -2 - invalid BAR number;
* eax = -3 - BAR contains no valid IO addres;
* eax = -4 - BAR addresses IO ports;
* eax = -5 - dynamic allocation error; otherwise
* eax = MMIO start address (in application's linear space).
Remarks:
* Low-level PCI access must be allowed (fn21:12)
* The system var [mmio_pci_addr] sets the actual PCI-address
* The granted MMIO addresses should be released after use (fn62:13)

* ecx = MMIO start address (in application's linear space).
Returns:
* eax = 1 if the block is successfully released;
* eax = 0 in case of reallocation error;
Remarks:
* A valid uMMIO block should exist at this address (fn62:12)
