-Added default requirements field in PmRequirements structure -Added notification of master when primary processor switches from forced powerdown to active state. Master has to make sure that all default requirements gets set before primary processor enters active state. -In PmMasterNotify, changed behavior when wake event is received: if primary processor is in sleep state, everything works as before, if primary processor is in forced powerdown, default requirements are requested and configured -In PmRequirementReleaseAll added a check is master using slave and if yes, usage flag and requirements are cleared -Added PmRequirementRequestDefault function called before primary processor switches from forced powerdown to active. Function automatically requests all default requirements which are later configured by PmRequirementUpdateScheduled -In PmRequirementUpdateScheduled when swapping requirements added a check whether master has default requirements. If yes, default reqs are saved as next reqs instead of current. Default requirements have priority over current requirement. Example: RPU0 keeps boot code in one TCM bank and when booted, during the runtime, it keeps that bank in retention. For this bank RPU0 should have default requirements = on state, and when it boots up it can request retention. If default requirements wouldn't exist, it would have to request for boot bank to switch from retention to on before calling self suspend, just to get on state in scheduled reqs Signed-off-by: Mirela Simonovic <mirela.simonovic@aggios.com> Acked-by: Sören Brinkmann <soren.brinkmann@xilinx.com> Acked-by: Jyotheeswar Reddy Mutthareddyvari <jyothee@xilinx.com> |

embeddedsw.git - repo for standalone software All software is version less and divided into three directories - lib contains bsp, zynq fsbl and software services like xilisf - license.txt contains information about the various licenses and copyrights - XilinxProcessorIPLib contains all drivers - ThirdParty software from third party like light weight IP stack - mcap software for using MCAP interface on Ultra Scale boards to program 2nd level bitstream Every driver/lib/apps/services has these sub-directories 1. data - contains tcl, mdd, testapp tcl or header files used in SDK 2. doc - documentation of source code in form of pdf or html 3. examples - illustrating different use cases of driver 4. src - driver interface code implementing functionality of IP <repo> |-XilinxProcessorIPLib | |- drivers | |- uartps | |- data | |- src | |- doc | |- examples | |-lib | |- bsp | |- standalone | |- data | |- src | |- cortexa9 | |- microblaze | |- common | |- profile | |- doc | |- xilkernel | |- data | |- doc | |- src | |- sw_apps | |- zynq_fsbl [described below] | |- sw_services | |- xilffs | |- xilskey | |- xilmfs | |- xilrsa | |- xilflash | |- xilisf | | Note - All these are libraries and utilize drivers | |-ThirdParty | |- sw_services | |- lwip140 | |-mcap | |-linux Building FSBL from git: FSBL has 3 directories. 1. data - It contains files for SDK 2. src - It contains the FSBK source files 3. misc - It contains miscelanious files required to compile FSBL for zc702, zc706, zed and microzed boards. It also contains the ps7_init_gpl.[c/h] with gpl header in respective board directories. How to compile FSBL: 1.Go to the Fsbl src directory "lib/sw_apps/zynq_fsbl/src/" 2. make "BOARD=<>" "CC=<>" a. Values for BOARD are zc702, zc706, zed, microzed b. Value for CC is arm-xilinx-eabi-gcc. Default value is also same. 3.Give "make" to compile the fsbl with BSP. By default it is built for zc702 board with arm-xilinx-eabi-gcc compiler 4.Below are the examples for compiling for different options a. To generate Fsbl for zc706 board i.make "BOARD=zc706" b.To generate Fsbl for zc702 board with debug enable and RSA support i.make "BOARD=zc702" "CFLAGS=-DFSBL_DEBUG_INFO -DRSA_SUPPORT" c.To generate Fsbl for zc706 board and compile with arm-xilinx-eabi-gcc with MMC support i.make "BOARD=zc706" "CC=arm-xilinx-eabi-gcc" "CFLAGS=-DMMC_SUPPORT"
