* ARM: compiler options cleanup - improve tool chain supportWolfgang Denk2009-08-21-3/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some time there have been repeated reports about build problems with some ARM (cross) tool chains. Especially issues about (in)compatibility with the tool chain provided runtime support library libgcc.a caused to add and support a private implementation of such runtime support code in U-Boot. A closer look at the code indicated that some of these issues are actually home-made. This patch attempts to clean up some of the most obvious problems and make building of U-Boot with different tool chains easier: - Even though all ARM systems basicy used the same compiler options to select a specific ABI from the tool chain, the code for this was distributed over all cpu/*/config.mk files. We move this one level up into lib_arm/config.mk instead. - So far, we only checked if "-mapcs-32" was supported by the tool chain; if yes, this was used, if not, "-mabi=apcs-gnu" was selected, no matter if the tool chain actually understood this option. There was no support for EABI conformant tool chains. This patch implements the following logic: 1) If the tool chain supports "-mabi=aapcs-linux -mno-thumb-interwork" we use these options (EABI conformant tool chain). 2) Otherwise, we check first if "-mapcs-32" is supported, and then check for "-mabi=apcs-gnu" If one test succeeds, we use the first found option. 3) In case 2), we also test if "-mno-thumb-interwork", and use this if the test succeeds. [For "-mabi=aapcs-linux" we set "-mno-thumb-interwork" mandatorily.] This way we use a similar logic for the compile options as the Linux kernel does. - Some EABI conformant tool chains cause external references to utility functions like raise(); such functions are provided in the new file lib_arm/eabi_compat.c Note that lib_arm/config.mk gets parsed several times, so we must make sure to add eabi_compat.o only once to the linker list.

* ARM EABI: add new helper functions resp. function namesWolfgang Denk2009-08-09-9/+33
| | | | | | | | | | | The ARM EABI defines new names for GCC helper functions, and GCC seems to need some new functions as well. This patch is a minimal-invasive approach to fix problems with EABI conformant tool chains (to be used with "USE_PRIVATE_LIBGCC=yes").

* Make linking against libgcc configurableWolfgang Denk2009-07-27-8/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | Many (especially ARM) tool chains seem to come with broken or otherwise unusable (for the purposes of builing U-Boot) run-time support libraries `libgcc.a'. By using the "USE_PRIVATE_LIBGCC" setting we allow to use alternative libraries instead. "USE_PRIVATE_LIBGCC" can either be set as an environment variable in the shell, or as a command line argument when running "make", i. e. $ make USE_PRIVATE_LIBGCC=yes or $ USE_PRIVATE_LIBGCC=yes $ export USE_PRIVATE_LIBGCC $ make The value of "USE_PRIVATE_LIBGCC" is the name of the directory which contains the alternative run-time support library `libgcc.a'. The special value "yes" selects the directory $(OBJTREE)/lib_$(ARCH) . Note that not all architectures provide an alternative `libgcc.a' in their lib_$(ARCH) directories - so far, only ARM does.

* stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD2009-07-18-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far the console API uses the following naming convention: ======Extract====== typedef struct device_t; int device_register (device_t * dev); int devices_init (void); int device_deregister(char *devname); struct list_head* device_get_list(void); device_t* device_get_by_name(char* name); device_t* device_clone(device_t *dev); ======= which is too generic and confusing. Instead of using device_XX and device_t we change this into stdio_XX and stdio_dev This will also allow to add later a generic device mechanism in order to have support for multiple devices and driver instances.

* lib_arch/board.c: Move malloc initialization before flash_init()Stefan Roese2009-06-12-3/+3
| | | | | | | | | | | | | | | | | | | This patch moves the malloc initialization before calling flash_init(). Upcoming changes to the NOR FLASH common CFI driver with optional MTD infrastructure and MTD concatenation support will call malloc(). And nothing really speaks against enabling malloc just a little earlier in the boot stage. Some architectures already enable malloc before calling flash_init() so they don't need any changes here.

So, to make sure this flag is set on boards skipping relocation, this is added to the initialisation of U-boot at a moment where it is safe to do so. Signed-off-by: Remy Bohmer <linux@bohmer.net>
