2013-08-09powerpc/mpc8xxx: Set inactive csn_bnds to 0xffffffffYork Sun
When chip select interleaving is enabled, cs0_bnds is used for address binding. Other csn_bnds are not used. When two controllers interleaving is enabled, cs0_bnds of both controllers are used, other csn_bnds are not. However, the unused csn_bnds may be used internally for calculating addresses for calibration. Setting those registers to 0 may confuse controllers in some cases. Instead, setting them to 0xffffffff together with normal LAWs will guarantee the address is not mapped to DDR. Signed-off-by: York Sun <yorksun@freescale.com>

Prepare for emulator support for mpc85xx parts. Disable DDR training and skip wrlvl_cntl_2 and wrlvl_cntl_3 registers. These two registers improve stability but not supported by emulator.

2013-08-09powerpc/srio: Update the SRIO LIODN registers and ID table macroLiu Gang
For some PowerPC platforms, LIODN registers for SRIO ports are in SRIO register address space. So the ccsr_rio structure should be updated for those LIODN registers. In addition, add a new macro "SET_SRIO_LIODN_BASE" to create the SRIO LIODN ID table based on the SRIO LIODN register address.

If the end address __bss_end is not alignment to 4byte, it will be an infinite loop. 1. The reset action stoped depending on the reset address is greater than or equal the end address of the BSS. 2.

2013-06-20powerpc/mpc85xx: support application without resetvec segment in the linker ↵Ying Zhang
script For SD/SPI 2-stage bootloader, the On-Chip Rom code loads the SPL into L2 SRAM, then jump to it to begin execution. After that, the SPL loads the final uboot image into DDR, then jump to it to begin execution. The segment .resetvec in the SPL and in final U-boot is useless. So, add new symbols CONFIG_SYS_MPC85XX_NO_RESETVEC for this application. If CONFIG_SYS_MPC85XX_NO_RESETVEC is set, the segment .resetvec is excluded and the segment .bootpg is placed in the previous 4K of the segment .text.

2013-06-20powerpc/t4qds: Slave module for boot from SRIO and PCIELiu Gang
When a T4 board boots from SRIO or PCIE, it needs to finish these processes: 1. Set all the cores in holdoff status. 2. Set the boot location to one PCIE or SRIO interface by RCW. 3. Set a specific TLB entry for the boot process. 4. Set a LAW entry with the TargetID of one PCIE or SRIO for the boot. 5. Set a specific TLB entry in order to fetch ucode and ENV from master. 6. Set a LAW entry with the TargetID one of the PCIE ports for ucode and ENV. 7. Slave's u-boot image should be generated specifically by make xxxx_SRIO_PCIE_BOOT_config.

2013-06-20powerpc/boot: Change the macro of Boot from SRIO and PCIE master moduleLiu Gang
Currently, the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" can enable the master module of Boot from SRIO and PCIE on a platform. But this is not a silicon feature, it's just a specific booting mode based on the SRIO and PCIE interfaces. So it's inappropriate to put the macro into the file arch/powerpc/include/asm/config_mpc85xx.h. Change the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" to "CONFIG_SRIO_PCIE_BOOT_MASTER", remove them from arch/powerpc/include/asm/config_mpc85xx.h file, and add those macros in configuration header file of each board which can support the master module of Boot from SRIO and PCIE.
