* ARM: compiler options cleanup - improve tool chain supportWolfgang Denk2009-08-211-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* rm9200 lowevel_init: don't touch reserved/readonly registersDavid Brownell2009-08-031-12/+2
| | | | | | | | | | | | | | | | | | | For some reason the AT91rm9200 lowlevel init writes to a bunch of reserved or read-only addresses. All the boards seem to define the value-to-be-written values as zero ... but they shouldn't actually be writing *anything* there. No documented erratum justifies these accesses. It looks like maybe some pre-release BDI-2000 setup code has been carried along by cargo cult programming since at least late 2004 (per GIT history). Here's a patch disabling what seems to be bogosity. Tested on a csb337; there were no behavioral changes.

* i2c: Create common default i2c_[set|get]_bus_speed() functionsPeter Tyser2009-06-121-10/+0
| | | | | | | | | | | | | New default, weak i2c_get_bus_speed() and i2c_set_bus_speed() functions replace a number of architecture-specific implementations. Also, providing default functions will allow all boards to enable CONFIG_I2C_CMD_TREE. This was previously not possible since the tree-form of the i2c command provides the ability to display and modify the i2c bus speed which requires i2c_[set|get]_bus_speed() to be present.
