* ARM: compiler options cleanup - improve tool chain supportWolfgang Denk2009-08-21-40/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, waiting for auto-negotiation would only occur if a valid link had been detected. Problems arose when attempting to use a tsec immediately after bootup but before link was achieved, eg: => dhcp Auto-neg error, defaulting to 10BT/HD eTSEC1: No link. Auto-neg error, defaulting to 10BT/HD eTSEC2: No link. => With this patch applied the same operation as above resulted in: => dhcp Waiting for PHY auto negotiation to complete. done Enet starting in 1000BT/FD Speed: 1000, full duplex Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes the device wait for up to 5 seconds for the link to come up, similar to what many of the other network drivers do. This avoids confusing situations where, e.g., a tftp fails when initiated early after U-boot has started (before the link has come up).

| * 85xx: Fix addrmap to include memoryKumar Gala2009-08-14-6/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When we init the addrmap based on the TLB we will not end up getting the TLB that covers memory if we are using SPD. The reason is we haven't relocated at the point that we setup the memory TLB and thus it will not get setup in the addrmap. Instead we can just walk over the TLB array after we've relocated and see all the TLBs that have been set and use that information to populate the initial addrmap. By doing this we insure that we get the TLB entries that cover memory. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
