/*! \addtogroup ADDR_SPACE_MGR_REMAP Address Space Mapping Control
*
* This group API provides functions to map and remap selected address ranges
* into the accessible (visible) views of the MPU and non MPU address spaces.
*
* \b Caveats
*
* \b NOTE: Caution should be observed when remapping address 0 to different
* memory. The code performing the remapping operation should not be executing
* in the address range being remapped to different memory.
*
* For example, if address 0 is presently mapped to OCRAM and the code is
* preparing to remap address 0 to SDRAM, then the code must not be executing in
* the range 0 to 64 KB as this address space is about to be remapped to
* different memory. If the code performing the remap operation is executing
* from OCRAM then it needs to be executing from its permanently mapped OCRAM
* address range in upper memory (i.e. ALT_OCRAM_LB_ADDR to ALT_OCRAM_UB_ADDR).
*
* \b NOTE: The MPU address space view is controlled by two disparate hardware
* control interfaces: the L3 remap register and the L2 cache address filtering
* registers. To complicate matters, the L3 remap register is write-only which
* means not only that current remap register state cannot be read but also that
* a read-modify-write operation cannot be performed on the register.
*
* This should not present a problem in most use case scenarios except for the
* case where a current MPU address space mapping of 0 to SDRAM is being changed
* to to a mapping of 0 to Boot ROM or OCRAM.
*
* In this case, a two step process whereby the L3 remap register is first set
* to the new desired MPU address 0 mapping and then the L2 cache address
* filtering registers have their address ranges adjusted accordingly must be
* followed. An example follows:
\verbatim
// 1 MB reset default value for address filtering start
#define L2_CACHE_ADDR_FILTERING_START_RESET 0x100000
uint32_t addr_filt_start;
uint32_t addr_filt_end;
// Perform L3 remap register programming first by setting the desired new MPU
// address space 0 mapping. Assume OCRAM for the example.
alt_addr_space_remap(ALT_ADDR_SPACE_MPU_ZERO_AT_OCRAM, ...);
// Next, adjust the L2 cache address filtering range. Set the start address to
// the default reset value and retain the existing end address configuration.
alt_l2_addr_filter_cfg_get(&addr_filt_start, &addr_filt_end);
if (addr_filt_start != L2_CACHE_ADDR_FILTERING_START_RESET)
{
alt_l2_addr_filter_cfg_set(L2_CACHE_ADDR_FILTERING_START_RESET, addr_filt_end);
}

/*! \addtogroup ADDR_SPACE_MGR_MEM_COHERENCE ACP Memory Coherence and ID Mapping
*
* This API provides management of the ACP ID Mapper that enables data coherent
* access to the MPU address space by external masters. The set of external
* masters include L3 master peripherals and FPGA soft IP.
*
* The Accelerator Coherency Port (ACP) allows peripherals - including FPGA
* based soft IP - to maintain data coherency with the Cortex-A9 MPCore
* processors and the Snoop Control Unit (SCU).
*
* The ACP supports up to six masters. However, soft IP implemented in the FPGA
* fabric can have a larger number of masters that need to access the ACP. The
* ACP ID Mapper expands the number of masters able to access the ACP. The ACP
* ID Mapper is situated between the interconnect and the ACP of the MPU
* subsystem. It has the following characteristics:
* * Support for up to six concurrent ID mappings.
* * 1 GiB coherent window into 4 GiB MPU address space
* * Remaps the 5-bit user sideband signals used by the Snoop Control Unit (SCU)
* and L2 cache.
*
* The function of the ACP ID Mapper is to map 12-bit Advanced Microcontroller
* Bus Architecture (AMBA) Advanced eXtensible Interface (AXI) IDs (input
* identifiers) from the Level 3 (L3) interconnect to 3-bit AXI IDs (output
* identifiers) required by the ACP slave port.
*
* The ACP ID Mapper supports the two ID mapping modes:
* * Dynamic Mapping - In this mode an input ID is automatically mapped to an
* available output ID. The dynamic mode is more flexible because the hardware
* handles the mapping. The hardware mapping allows an output ID to be used
* for more than one input ID. Output IDs are assigned to input IDs on a
* first-come, first-served basis.
* * Fixed Mapping - In this mode there is a one-to-one mapping from input IDs
* to output IDs.
*
* Out of the total of eight ACP output ID values, only six are available to the
* ACP ID Mapper for remapping. The first two output IDs (0 and 1) are
* dedicated to the Cortex-A9 processor cores in the MPU subsystem, leaving the
* last six output IDs (2-7) available to the ACP ID mapper. Output IDs 2-6
* support fixed and dynamic modes of operation while output ID 7 supports
* dynamic mode only.
*
* The following table summarizes the usage of the 3-bit ouput ID values by the
* ACP ID Mapper and their settings at reset.
*
* Output ID | Usage | Reset State
* :-----------|:--------------------------------------------------|:------------
* 0 | Reserved for Cortex-A9 cores. | -
* 1 | Reserved for Cortex-A9 cores. | -
* 2 | Assigned to Debug Access Port (DAP) input ID at | Fixed
* : | reset. After reset, can be reconfigured to either | DAP Master
* : | fixed or dynamic. |:
* 3 | Configurable fixed or dynamic mode. | Dynamic
* 4 | Configurable fixed or dynamic mode. | Dynamic
* 5 | Configurable fixed or dynamic mode. | Dynamic
* 6 | Configurable fixed or dynamic mode. | Dynamic
* 7 | Dynamic mode only. | Dynamic
*
* Where <em>Output ID</em> is the ACP ID Mapper output value that goes to the ACP.
*
* Additionally, for masters unable to drive the AXI user sideband signals of
* incoming transactions, the ACP ID Mapper allows control of the AXI user
* sideband signal values. Not all masters drive these signals, so the ACP ID
* Mapper makes it possible to drive the 5-bit user sideband signal with either
* a default value (in dynamic mode) or specific values (in fixed mode).
*
* The ACP ID Mapper can also control which 1 GiB coherent window into memory is
* accessed by masters of the L3 interconnect. Each fixed mapping can be
* assigned a different user sideband signal and memory window to allow specific
* settings for different masters. All dynamic mappings share a common user
* sideband signal and memory window setting. One important exception, however,
* is that the ACP ID mapper always allows user sideband signals from the
* FPGA-to-HPS bridge to pass through to the ACP regardless of the configured
* user sideband value associated with the ID.
*
* The ACP ID Mapper has a 1 GiB address window into the MPU address space, which
* is by default a view into the bottom 1 GiB of SDRAM. The ACP ID Mapper allows
* transactions to be routed to different 1 GiB-sized memory views, called pages,
* in both dynamic and fixed modes.
*
* See: <em>Chapter 6: Cortex-A9 Microprocessor Unit Subsystem</em> in
* <em>Volume 3: Hard Processor System Technical Reference Manual</em> of the
* <em>Arria V or Cyclone V Device Handbook</em> for a complete discussion of
