2011-12-20AVR32: fix timer_init() functionSven Schnelle
timer_init() now returns an int (the error code) instead of void. This makes compilation fail with: interrupts.c:111: error: conflicting types for 'timer_init' /home/svens/u-boot/u-boot/include/common.h:246: error: previous declaration of 'timer_init' was here make[1]: *** [interrupts.o] Error 1 Signed-off-by: Sven Schnelle <svens@stackframe.org> Acked-by: Andreas Bießmann <andreas.devel@googlemail.com> Signed-off-by: Anatolij Gustschin <agust@denx.de>

2011-03-27rename _end to __bss_end__Po-Yu Chuang
Currently, _end is used for end of BSS section. We want _end to mean end of u-boot image, so we rename _end to __bss_end__ first. Signed-off-by: Po-Yu Chuang <ratbert@faraday-tech.com>
2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
2010-10-26Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new <asm-offsets.h> file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.

2010-09-03avr32: Add simple paging supportHaavard Skinnemoen
Use the MMU hardware to set up 1:1 mappings between physical and virtual addresses. This allows us to bypass the cache when accessing the flash without having to do any physical-to-virtual address mapping in the CFI driver. The virtual memory mappings are defined at compile time through a sorted array of virtual memory range objects. When a TLB miss exception happens, the exception handler does a binary search through the array until it finds a matching entry and loads it into the TLB. The u-boot image itself is covered by a fixed TLB entry which is never replaced. This makes the 'saveenv' command work again on ATNGW100 and other boards using the CFI driver, hopefully without breaking any rules. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
2010-09-03avr32: Print unrelocated PC on exceptionHaavard Skinnemoen
In addition to the real PC value, also print the value of PC after subtracting the relocation offset. This value will match the address in the ELF file so it's much easier to figure out where things went wrong. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
2010-07-04Make sure that argv[] argument pointers are not modified.Wolfgang Denk
The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...
