TI DaVinci: DM646x: Initial Support for DM646x SOC

2009-10-13T11:17:34Z

DM646x is an SOC from TI which has both an ARM and a DSP. There are multiple variants of the SOC mainly dealing with different core speeds. This patch adds the initial framework for the DM646x SOC. Signed-off-by: Sandeep Paulraj

ARM: compiler options cleanup - improve tool chain support

2009-08-21T21:11:53Z

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: unify linker script

2009-06-12T18:39:52Z

all arm boards except a few use the same cpu linker script so move it to cpu/$(CPU) that could be overwrite in following order SOC BOARD via the corresponding config.mk Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD

ARM DaVinci: Reset with watchdog enabled

2009-06-12T18:39:51Z

Once the Davinci watchdog has been enabled, the timeout value cannot be changed. If the timeout in use is long, it can take a long time for card to reset. By writing an invalid service key, we can trigger an immediate reset. Signed-off-by: Thomas Lange

ARM DaVinci:Consolidate common u-boot.lds

2009-06-12T18:39:49Z

The u-boot.lds is common for all DaVinci boards. The patch removes multiple instances and moves the u-boot.lds to /cpu/arm926ejs/davinci folder. This addresses one of the comments i received while submitting patches for DM3xx Signed-off-by: Sandeep Paulraj
