/*
* Erratum A-004034
* Affects: SRIO
* Description: During port initialization, the SRIO port performs
* lane synchronization (detecting valid symbols on a lane) and
* lane alignment (coordinating multiple lanes to receive valid data
* across lanes). Internal errors in lane synchronization and lane
* alignment may cause failure to achieve link initialization at
* the configured port width.
* An SRIO port configured as a 4x port may see one of these scenarios:
* 1. One or more lanes fails to achieve lane synchronization. Depending
* on which lanes fail, this may result in downtraining from 4x to 1x
* on lane 0, 4x to 1x on lane R (redundant lane).
* 2. The link may fail to achieve lane alignment as a 4x, even though
* all 4 lanes achieve lane synchronization, and downtrain to a 1x.
* An SRIO port configured as a 1x port may fail to complete port
* initialization (PnESCSR[PU] never deasserts) because of scenario 1.
* Impact: SRIO port may downtrain to 1x, or may fail to complete
* link initialization. Once a port completes link initialization
* successfully, it will operate normally.

powerpc/corenet_ds: Master module for boot from PCIE For the powerpc processors with PCIE interface, boot location can be configured from one PCIE interface by RCW. The processor booting from PCIE can do without flash for u-boot image. The image can be fetched from another processor's memory space by PCIE link connected between them. The processor booting from PCIE is slave, the processor booting from normal flash memory space is master, and it can help slave to boot from master's memory space. When boot from PCIE, slave's core should be in holdoff after powered on for some specific requirements. Master will release the slave's core at the right time by PCIE interface. Environment and requirement: master: 1. NOR flash for its own u-boot image, ucode and ENV space. 2. Slave's u-boot image is in master NOR flash. 3. Normally boot from local NOR flash. 4. Configure PCIE 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 one PCIE interface by RCW. 3. RCW should configure the SerDes, PCIE interfaces correctly. 4. Must set all the cores in holdoff by RCW. 5. Must be powered on before master's boot. For the master module, need to finish these processes: 1. Initialize the PCIE port and address space. 2. Set inbound PCIE windows covered slave's u-boot image stored in master's NOR flash. 3. Set outbound windows in order to configure slave's registers for the core's releasing. 4. Should set the environment variable "bootmaster" to "PCIE1", "PCIE2" or "PCIE3" using the following command: setenv bootmaster PCIE1 saveenv Signed-off-by: Liu Gang <Gang.Liu@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

powerpc/corenet_ds: Master module for boot from PCIE For the powerpc processors with PCIE interface, boot location can be configured from one PCIE interface by RCW. The processor booting from PCIE can do without flash for u-boot image. The image can be fetched from another processor's memory space by PCIE link connected between them. The processor booting from PCIE is slave, the processor booting from normal flash memory space is master, and it can help slave to boot from master's memory space. When boot from PCIE, slave's core should be in holdoff after powered on for some specific requirements. Master will release the slave's core at the right time by PCIE interface. Environment and requirement: master: 1. NOR flash for its own u-boot image, ucode and ENV space. 2. Slave's u-boot image is in master NOR flash. 3. Normally boot from local NOR flash. 4. Configure PCIE 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 one PCIE interface by RCW. 3. RCW should configure the SerDes, PCIE interfaces correctly. 4. Must set all the cores in holdoff by RCW. 5. Must be powered on before master's boot. For the master module, need to finish these processes: 1. Initialize the PCIE port and address space. 2. Set inbound PCIE windows covered slave's u-boot image stored in master's NOR flash. 3. Set outbound windows in order to configure slave's registers for the core's releasing. 4. Should set the environment variable "bootmaster" to "PCIE1", "PCIE2" or "PCIE3" using the following command: setenv bootmaster PCIE1 saveenv Signed-off-by: Liu Gang <Gang.Liu@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
