* arm: keep all sections in ELF fileAlbert ARIBAUD2013-12-07-14/+18
| | | | | | | | | | Current LDS files /DISCARD/ a lot of sections when linking ELF files, causing diagnostic tools such as readelf or objdump to produce partial output. Keep all section at link stage, filter only at objcopy time so that .bin remains minimal.

Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file. Note: 'git show' will also list two files just because they are new: include/configs/am335x_igep0033.h include/configs/omap3_igep00x0.h

| * ARM: mxs: Setup stack in JTAG modeMarek Vasut2013-10-17-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case the MX23/MX28 is switched into JTAG mode via the BootMode select switches, the BootROM bypasses the CPU core registers initialization. This in turn means that the Stack Pointer (SP) register is not set as it is in every other mode of operation, but instead is only zeroed out. To prevent U-Boot SPL from crashing in this obscure JTAG mode, configure the SP to point at the CONFIG_SYS_INIT_SP_ADDR if the SP is zeroed out. Note that in case the SP is already configured, we must preserve that exact SP value and must not modify it. This is important since in every other mode but the JTAG mode, the SPL returns into the BootROM and BootROM in turn loads U-Boot itself. If the SP were to be corrupted, the BootROM won't be able to continue it's operation after returned from SPL and the system would crash. Finally, add the JTAG mode switch identifier, so it's not recognised as Unknown mode.

| * ARM: mxs: rename function that sets AUTO_RESTART flagHector Palacios2013-08-31-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AUTO_RESTART flag of HW_RTC_PERSISTENT0 register will power up the chip automatically 180ms after power down. This bit must be enabled by the boot loader to ensure the target can start upon hardware reset or watchdog reset even when powered from a battery. Currently the function named 'mxs_power_clear_auto_restart()' is setting this flag although the 'clear' in its name suggest the opposite. This patch renames the function to 'mxs_power_set_auto_restart()' and removes the comment about EVK revision A which was confusing because the function indeed was setting the flag.

The implementation here is mostly a glue code between MXSSB v0.4 and mkimage, but the long-term goal is to rectify this and merge MXSSB with mkimage more tightly. Once this code is properly in U-Boot, MXSSB shall be deprecated in favor of mkimage-mxsimage support. Note that the mxsimage generator needs libcrypto from OpenSSL, I therefore enabled the libcrypto/libssl unconditionally.
