Sequence in Step by Step. + a) Update RCW for slave with boot from SRIO port 0 configuration. + b) Program slave's U-Boot image, UCode, and ENV parameters into master's + NorFlash. + c) Start up master and it will boot up normally from its NorFlash. + Then, it will finish necessary configurations for slave's boot from + SRIO port 0. + d) Master will set inbound SRIO windows covered slave's U-Boot image stored + in master's NorFlash. + e) Master will set an inbound SRIO window covered slave's UCode stored in + master's NorFlash. + f) Master will set an inbound SRIO window covered slave's ENV stored in + master's NorFlash. + g) If need to release slave's core, master will set outbound SRIO windows + in order to configure slave's registers for the core's releasing. + h) If all cores of slave in holdoff, slave should be powered on before all + the above master's steps, and wait to be released by master. If not all + cores in holdoff, that means core 0 will start up normally, slave should + be powered on after all the above master's steps. In the startup phase + of the slave from SRIO, it will finish some necessary configurations. + i) Slave will set a specific TLB entry for the boot process. + j) Slave will set a LAW entry with the TargetID SRIO port 0 for the boot. + k) Slave will set a specific TLB entry in order to fetch UCode and ENV + from master. + l) Slave will set a LAW entry with the TargetID SRIO port 0 for UCode and ENV. + +How to use this feature: + To use this feature, you need to focus three points. + + 1. Slave's RCW with SRIO boot configurations, and all cores in holdoff + configurations if needed. + Please refer to the examples given above. + + 2. U-Boot image's compilation. + For master, U-Boot image should be generated specifically by + + make xxxx_SRIOBOOT_MASTER_config. + + For example, master U-Boot image used on P4080DS should be compiled with + + make P4080DS_SRIOBOOT_MASTER_config. + + For slave, U-Boot image should be generated specifically by + + make xxxx_SRIOBOOT_SLAVE_config. + + For example, slave U-Boot image used on P4080DS should be compiled with + + make P4080DS_SRIOBOOT_SLAVE_config. + + 3. Necessary modifications based on a specific environment. + For a specific environment, the SRIO port for boot, the addresses of the + slave's U-Boot image, UCode, ENV stored in master's NorFlash, and any other + configurations can be modified in the file: + include/configs/corenet_ds.h.
For the powerpc processors with SRIO interface, boot location can be configured from SRIO1 or SRIO2 by RCW. The processor booting from SRIO can do without flash for u-boot image. The image can be fetched from another processor's memory space by SRIO link connected between them.
The processor boots from SRIO is slave, the processor boots from normal flash memory space and can help slave to boot from its memory space is master. They are different environments and requirements:
master: 1. NOR flash for its own u-boot image, ucode and ENV space. 2. Slave's u-boot image in master NOR flash. 3. Normally boot from local NOR flash. 4. Configure SRIO switch system if needed. slave: 1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV. 2. Boot location should be set to SRIO1 or SRIO2 by RCW. 3. RCW should configure the SerDes, SRIO interfaces correctly. 4. Slave must be powered on after master's boot.
For the master module, need to finish these processes: 1. Initialize the SRIO port and address space. 2. Set inbound SRIO windows covered slave's u-boot image stored in master's NOR flash. 3. Master's u-boot image should be generated specifically by make xxxx_SRIOBOOT_MASTER_config 4. Master must boot first, and then slave can be powered on.

For the powerpc processors with SRIO interface, boot location can be configured from SRIO1 or SRIO2 by RCW. The processor booting from SRIO can do without flash for u-boot image. The image can be fetched from another processor's memory space by SRIO link connected between them.
The processor boots from SRIO is slave, the processor boots from normal flash memory space and can help slave to boot from its memory space is master. They are different environments and requirements:
master: 1. NOR flash for its own u-boot image, ucode and ENV space. 2. Slave's u-boot image in master NOR flash. 3. Normally boot from local NOR flash. 4. Configure SRIO switch system if needed. slave: 1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV. 2. Boot location should be set to SRIO1 or SRIO2 by RCW. 3. RCW should configure the SerDes, SRIO interfaces correctly. 4. Slave must be powered on after master's boot. 5. Must define CONFIG_SYS_QE_FMAN_FW_IN_REMOTE because of no ucode locally.
For the slave module, need to finish these processes: 1. Set the boot location to SRIO1 or SRIO2 by RCW. 2. Set a specific TLB entry for the boot process. 3. Set a LAW entry with the TargetID SRIO1 or SRIO2 for the boot. 4. Slave's u-boot image should be generated specifically by make xxxx_SRIOBOOT_SLAVE_config. This will set SYS_TEXT_BASE=0xFFF80000 and other configurations.

When boot from SRIO, slave's ucode can be stored in master's memory space, then slave can fetch the ucode image through SRIO interface. For the corenet platform, ucode is for Fman.
Master needs to: 1. Put the slave's ucode image into it's own memory space. 2. Set an inbound SRIO window covered slave's ucode stored in master's memory space. Slave needs to: 1. Set a specific TLB entry in order to fetch ucode from master. 2. Set a LAW entry with the TargetID SRIO1 or SRIO2 for ucode.

When boot from SRIO, slave's ENV can be stored in master's memory space, then slave can fetch the ENV through SRIO interface.
NOTE: Because the slave can not erase, write master's NOR flash by SRIO interface, so it can not modify the ENV parameters stored in master's NOR flash using "saveenv" or other commands.
Master needs to: 1. Put the slave's ENV into it's own memory space. 2. Set an inbound SRIO window covered slave's ENV stored in master's memory space. Slave needs to: 1. Set a specific TLB entry in order to fetch ucode and ENV from master. 2. Set a LAW entry with the TargetID SRIO1 or SRIO2 for ucode and ENV.

When boot from SRIO, slave's core can be in holdoff after powered on for some specific requirements. Master can release the slave's core at the right time by SRIO interface.
Master needs to: 1. Set outbound SRIO windows in order to configure slave's registers for the core's releasing. 2. Check the SRIO port status when release slave core, if no errors, will implement the process of the slave core's releasing. Slave needs to: 1. Set all the cores in holdoff by RCW. 2. Be powered on before master's boot.
