The `qoriq_e500` variant supports the P-series chips such as P1020, P2010 and P2020. The `qoriq_e6500_32` (32-bit ISA) and `qoriq_e6500_64` (64-bit ISA) variants support the T-series chips such as T2080 and T4240. The basic hardware initialization is not performed by the BSP. A boot loader with device tree support must be used to start the BSP, e.g. U-Boot. The BSP is known to run on these boards: * NXP P1020RDB * MicroSys miriac MPX2020 (System on Module) * Artesyn MVME2500 (VME64x SBC) * NXP T2080RDB * NXP T4240RDB * MEN G52A (CompactPCI Serial) The `qoriq_core_0` and `qoriq_core_1` variants should be used with care. They are inteded for a `RTEMS_MULTIPROCESSING` configuration on the P1020. Boot via U-Boot --------------- The application executable file (ELF file) must be converted to an U-Boot image. Use the following commands: :: powerpc-rtems5-objcopy -O binary app.exe app.bin gzip -9 -f -c app.bin > app.bin.gz mkimage -A ppc -O linux -T kernel -a 0x4000 -e 0x4000 -n RTEMS -d app.bin.gz app.img Use the following U-Boot commands to boot an application via TFTP download: :: tftpboot ${loadaddr} app.img && run loadfdt && bootm ${loadaddr} - ${fdt_addr} ; reset Clock Driver ------------ The clock driver uses two MPIC global timer (``QORIQ_CLOCK_TIMER`` and ``QORIQ_CLOCK_TIMECOUNTER``). In case ``QORIQ_IS_HYPERVISOR_GUEST`` is defined, then the PowerPC decrementer is used. Console Driver -------------- The console driver supports the on-chip NS16550 compatible UARTs. In case ``QORIQ_IS_HYPERVISOR_GUEST`` is defined, then the EPAPR byte channel is used for the console device. Network Interface Driver ------------------------ The network interface driver is provided by the `libbsd`. The DPAA is supported including 10Gbit/s Ethernet. Topaz Hypervisor Guest ---------------------- For a Topaz hypervisor guest configuration use: :: ../configure --enable-rtemsbsp=qoriq_e6500_32 \ QORIQ_IS_HYPERVISOR_GUEST=1 \ QORIQ_UART_0_ENABLE=0 \ QORIQ_UART_1_ENABLE=0 \ QORIQ_TLB1_ENTRY_COUNT=16 You may have to adjust the linker command file according to your partition configuration. ss555 ===== TODO. t32mppc ======= TODO. tqm8xx ====== TODO. virtex ====== TODO. virtex4 ======= TODO. virtex5 ======= TODO.
