2013-06-26x86: Support tracing functionSimon Glass
Some changes are needed to x86 timer functions to support tracing. Add these so that the feature works correctly. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-06-26exynos: Avoid function instrumentation for microsecond timerSimon Glass
For tracing to work it has to be able to access the microsecond timer without causing a recursive call to the function entry/exit handlers. Add attributes to the relevant functions to support this. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
2013-06-26arm: Implement the 'fake' go commandSimon Glass
Implement this feature on ARM for tracing. It would be nice to have generic bootm support so that it is easily implemented on any arch. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Albert ARIBAUD <albert.u.boot@aribaud.net>
2013-06-26Clarify bootm OS argumentsSimon Glass
At present the arguments to bootm are processed in a somewhat confusing way. Sub-functions must know how many arguments their calling functions have processed, and the OS boot function must also have this information. Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in the same way. Adjust the code so that arguments are removed from the list before calling a sub-function. This means that all functions can know that argv[0] is the first argument of which they need to take notice. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-06-26sandbox: Support trace featureSimon Glass
Support tracing on sandbox by adding suitable CONFIG options. To enable it, compile U-Boot with FTRACE=1. The timer functions are marked to skip tracing, since these are called from the tracing code itself, and we want to avoid an infinite loop. Signed-off-by: Simon Glass <sjg@chromium.org>

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

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.
