Microsemi IGLOO2 HPMS Security Configuration User Guide

IGLOO2 HPMS
Security Configuration

Introduction

The IGLOO2 devices offer extensive configurable access controls to the HPMS memory map. These controls are in AHB Bus Matrix Master/Slave Access.
You can access these controls from System Builder’s Security tab and select your security options by checking or unchecking the Read/Write checkboxes as desired for each of the Masters and Slaves (Figure 1).

Configuration Options

AHB Bus Matrix Master/Slave Access Configuration
Note that the master/slave access controls are restricted to those devices offering the Advanced Security Features. For devices offering baseline security only, all programmable accesses are granted and cannot be changed. The controls are grayed out.
The Master/Slave configuration tab defines how masters and slaves communicate and whether it also has write access when a master has read access. The AHB Bus Matrix can be configured to restrict those accesses.
The master/slave access is defined in the matrix as follows:

• R: Only Read access is available when Read is checked
• W: Only Write access is available when Write is checked.
• RW: Both Read and Write access are available when both Read and Write are checked

Whenever you restrict a master/slave access by un-checking the Read or Write access for a particular group of masters (masters are organized in three groups with respect to access configuration) the actual access is shown in the matrix.
eNVM blocks have special sectors that can be write protected. The number of special sectors depends on the device selected. The size of each sector is 4KB and the address range for each special sector is shown in blue in the GUI. Check the Use as ROM option to write protect these eNVM regions. The eNVM special sectors are hidden in the matrix when you open the configurator, and you must click the ‘+’ sign to show these special sectors (Figure 1-1).

Table 1 lists eNVM special sector address ranges.

Reads and Writes to Protected Areas
Based on your selections in this configurator, the AHB Switch Matrix disallows certain reads and writes.
Reads or writes to areas not allowed cause the AHB bus matrix to complete the transaction with an HRESP error indication. An error bit is set in the SW_ERRORSTATUS field of the MSS_EXTERNAL_SR register. An error occurs when one or more of the following happens:

• Write by an enabled master to a slave that is not RW
• Write by an enabled master to addresses not corresponding to a slave
• Write by the fabric master to the protected region
• Write by a disabled master to any location
• Read by an enabled master to any slave that is not R or RW
• Read by an enabled master to addresses not corresponding to a slave
• Read by the fabric master to the protected region
• Read by a disabled master to any location

The values entered in the configurator will be exported into the programming files for programming of the flash bits that control this functionality. The flash bits are loaded in the system registers at power up (or when the DEVRST_N external pad is asserted/de-asserted).
