But by looking at the TQM pcmcia driver, the problem is in the driver itself. That's where I suspect it should be fixed. Can you share the list of broken boards you detected please ? Thanks! Cheers

Hi, I'm running the compile tests for powerpc arch right now and I noticed many problems of this form: Configuring for PCIPPC2 board... interrupts.c: In function 'interrupt_init_cpu': interrupts.c:38: warning: implicit declaration of function 'GTREGREAD' interrupts.c:38: error: 'LOW_INTERRUPT_CAUSE_REGISTER' undeclared (first use in this function) interrupts.c:38: error: (Each undeclared identifier is reported only once interrupts.c:38: error: for each function it appears in.) interrupts.c:39: error: 'HIGH_INTERRUPT_CAUSE_REGISTER' undeclared (first use in this function) interrupts.c:41: error: 'ETHERNET0_INTERRUPT_CAUSE_REGISTER' undeclared (first use in this function) interrupts.c:42: error: 'ETHERNET1_INTERRUPT_CAUSE_REGISTER' undeclared (first use in this function) interrupts.c:43: error: 'ETHERNET2_INTERRUPT_CAUSE_REGISTER' undeclared (first use in this function) interrupts.c:45: error: 'ETHERNET0_INTERRUPT_MASK_REGISTER' undeclared (first use in this function) interrupts.c:46: error: 'ETHERNET1_INTERRUPT_MASK_REGISTER' undeclared (first use in this function) interrupts.c:47: error: 'ETHERNET2_INTERRUPT_MASK_REGISTER' undeclared (first use in this function) make[1]: *** [interrupts.o] Error 1 make: *** [arch/powerpc/cpu/74xx_7xx/lib74xx_7xx.o] Error 2 make: *** Waiting for unfinished jobs.... powerpc-linux-size: './u-boot': No such file This seems like noone actually tested compiling those boards with DEBUG enabled ... ever. Anyway, there seems to be an easy fix, add the following into the config file: #ifndef __ASSEMBLY__ #include <galileo/core.h> #endif There is a catch I don't quite understand though, that is, some boards include board/Marvell/include/mv_gen_reg.h instead. Which should be included in those config files? Is there some way to tell please? ========================================= As for the tqm-pcmcia problem, removing the #ifdef DEBUG fixed the problem with no growth in the u-boot.bin size. Though u-boot (elf binary) grew a bit (tested with ELDK4.2, gcc 4.2.2): With no gcc4.6 patches and unfixed: Configuring for TQM823L board... text data bss dec hex filename 260523 13960 25704 300187 4949b ./u-boot --------------------- SUMMARY ---------------------------- Boards compiled: 1 ---------------------------------------------------------- [u-boot]$ ls -la u-boot.bin -rwxrwxr-x 1 user user 274568 Oct 3 00:10 u-boot.bin With gcc4.6 patches and removed #ifdef DEBUG: Configuring for TQM823L board... text data bss dec hex filename 260547 13960 25704 300211 494b3 ./u-boot --------------------- SUMMARY ---------------------------- Boards compiled: 1 ---------------------------------------------------------- [u-boot]$ ls -la u-boot.bin -rwxrwxr-x 1 user user 274568 Oct 3 00:11 u-boot.bin Cheers
