* ARM: Add support for semihostingAndrey Smirnov2015-10-301-0/+1
| | | | | | | | | | Add semihosting API implementation and implement a filesystem driver to access debugging host filesystem using it. Tested on Freescale SabreSD board (i.MX6Q) using OpenOCD Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: compile bootm code depending on CONFIG_BOOTMSascha Hauer2013-09-241-1/+1
| | | | | | | | The bootm code is now independent from the actual bootm command, so compile the ARM specific bootm code based on CONFIG_BOOTM and not on CONFIG_CMD_BOOTM. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: Add assembler function to get runtime offsetSascha Hauer2012-09-091-0/+2
| | | | | | | This function returns the offset between the address barebox is linked at and the address barebox is currently running at. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Add pre-bootloader (pbl) image supportJean-Christophe PLAGNIOL-VILLARD2012-08-031-0/+4
| | | | | | | | | | | | | | | | | | | | | This allows for creating a pre-bootloader binary for - nand boot - mmc boot - compressed image The pbl will be incharge of the lowlevel init if needed. The barebox will skip it. Import string functions from linux 3.4 (arch/arm/boot/compressed/string.c) and implement a dummy panic. For now on introduce dummy zbarebox* targets and c code that will contain later the decompressor. This only implemeted on ARM. This patch is based on Sascha Hauer <s.hauer@pengutronix.de> Add compressed image support patch Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>

| | | | | | | | | | This patch removes the inclusion of libgcc functions into Barebox on the ARM architecture. Only the really needed functions are provided in the lib_arm directory. Those implementations are copied from Linux where they are well proven related to reliably, performance.
