| * ARM: MXS: Add multiimage supportSascha Hauer2015-01-052-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Freescale MXS SoCs have a multi staged boot process which needs different images composed out of different binaries. The ROM executes a so called bootstream which contains multiple executables. The first one is executed in SRAM and the purpose of this binary is to setup the internal PMIC and the SDRAM. The second image is usually the bootloader itself. In case of barebox the bootstream is composed out of the self extracting barebox image (pblx) and the prepare stage for setting up the SDRAM. The bootstream image itself is useful for USB boot, but for booting from SD cards or NAND a BCB header has to be prepended to the image. In case of SD boot the image has the .mxssd file extension in barebox. Since the bootstream images are encrypted they are not suitable for 2nd stage execution. For this purpose the 2nd stage images are generated. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot has code to replace the infamous Freescale bootlet code. This patch adds this for barebox with some changes: - Separate it more into mx23/mx28 functions instead of mxs functions with #ifdefs for the actual SoC - Add mx2x_power_init_battery_input() power entry point for boards which have a regulated input on the battery pin to supply the board. - Export more functions to be more flexible when boards need non standard setup.

| * | arm: do section garbage collection also with modules enabledLucas Stach2014-12-171-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot of the arm build (especially PBL stuff) depends on section garbage collection to be enabled. If it is disabled a lot of targets fail to link properly. If module support is enabled garbage collection was disabled on the premise that we throw away too many function which may be needed in later modules. The proper way to keep the functions around for use in modules, which already works, is to annotate them with EXPORT_SYMBOL. As module support is still marked as experimental I think it's reasonable to expect users to make sure all symbols that are used by their modules are properly annotated.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 4b17d73c7da2, as it is incomplete and partially broken. ARCH_IMX_EXTERNAL_BOOT_NAND does not depend on MTD, it just uses some defines from the mtd/nand header, but does not actually depend on MTD being compiled in. For the other two cases there is a more complete fix merged with commit 57b584d748d4 that also enables the needed MTD write support. Fixes: (MACH_TX25 && MACH_PCA100 && MACH_PCM038) selects ARCH_IMX_EXTERNAL_BOOT_NAND which has unmet direct dependencies (ARCH_IMX && MTD) Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, MIPS is the only architecture that needs include/generated/asm-offsets.h, but we have got ./Kbuild file now. It is a good reason to move asm-offsets.h rule from arch/mips/Makefile to ./Kbuild and add dummy asm-offsets.c for the other architectures. asm-offsets.h would be useful for all the architectures. This commit does not implement include/generated/bounds.h, but if necessary, it is easy to implement it.

For the already existing mcr instruction see the newly added comment. This patch also unifies handling of ARMv6 and ARMv7, the isb instruction can also be done on the latter via mcr which simplifies the code a bit.
