|
||||
* 5.00 pkp 12/15/14 Initial release
|
||||
* 5.04 pkp 01/12/16 Added platform information support for Cortex-A53 32bit
|
||||
* mode
|
||||
* 6.00 mus 17/08/16 Removed unused variable from XGetPlatform_Info
|
||||
* 6.4 ms 05/23/17 Added PSU_PMU macro to support XGetPSVersion_Info
|
||||
* function for PMUFW.
|
||||
* ms 06/13/17 Added PSU_PMU macro to provide support of
|
||||
* XGetPlatform_Info function for PMUFW.
|
||||
* mus 08/17/17 Add EL1 NS mode support for
|
||||
* XGet_Zynq_UltraMp_Platform_info and XGetPSVersion_Info
|
||||
* APIs.
|
||||
* 7.0 aru 03/15/19 Check for versal before aarch64 and armr5
|
||||
* in XGetPlatform_Info()
|
||||
* 7.2 adk 08/01/20 Added versal support for the XGetPSVersion_Info function.
|
||||
* 7.6 mus 08/23/21 Updated prototypes for functions which are not taking any
