* powerpc: mpc85xx/mpc86xx: Fix off-by-one boundary checking with ARRAY_SIZEAxel Lin2013-06-20-25/+25

* powerpc/mpc85xx: modify the functionality clear_bss and aligning the end ↵Ying Zhang2013-06-20-1/+3
| | | | | | | | | | | | | | | | | | | | address of the BSS There will clear the BSS in the function clear_bss(), the reset address of the BSS started from the __bss_start, and increased by four-byte increments, finally stoped depending on the address is equal to the _bss_end. 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. The end address of the BSS should be 4byte aligned. Because the reset unit is 4 Bytes. This patch is on top of the patch "powerpc/mpc85xx: support application without resetvec segment in the linker script".

* powerpc/mpc85xx: support application without resetvec segment in the linker ↵Ying Zhang2013-06-20-0/+22
| | | | | | | | | | | | | | | | 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.

* powerpc/mpc85xx: work around erratum A-006593Scott Wood2013-06-20-0/+8
| | | | | | | | | | | | Erratum A-006593 is "Atomic store may report failure but still allow the store data to be visible". The workaround is: "Set CoreNet Platform Cache register CPCHDBCR0 bit 21 to 1'b1. This may have a small impact on synthetic write bandwidth benchmarks but should have a negligible impact on real code."

* powerpc/t4qds: Slave module for boot from SRIO and PCIELiu Gang2013-06-20-0/+1
| | | | | | | | | | | | | | | | | | | | | 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. This will set SYS_TEXT_BASE=0xFFF80000 and other configurations.

* powerpc/boot: Change the macro of Boot from SRIO and PCIE master moduleLiu Gang2013-06-20-7/+3
| | | | | | | | | | | | | | | | | 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.
