2011-11-16board/esd/cpci750/sdram_init.c: Fix GCC 4.6 build warningsWolfgang Denk
Fix: sdram_init.c: In function 'check_dimm': sdram_init.c:267:50: warning: variable 'trrd_clocks' set but not used [-Wunused-but-set-variable] sdram_init.c:267:37: warning: variable 'tras_clocks' set but not used [-Wunused-but-set-variable] sdram_init.c:267:24: warning: variable 'trcd_clocks' set but not used [-Wunused-but-set-variable] sdram_init.c:267:8: warning: variable 'trp_clocks' set but not used [-Wunused-but-set-variable] sdram_init.c:253:16: warning: variable 'spd_checksum' set but not used [-Wunused-but-set-variable] sdram_init.c: In function 'initdram': sdram_init.c:1693:14: warning: variable 's1' set but not used [-Wunused-but-set-variable] sdram_init.c:1693:6: warning: variable 's0' set but not used [-Wunused-but-set-variable] Biggest part o the fix is converting the custom debug code to standard debug(). No attempts were made to cleanup the code. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Reinhard Arlt <reinhard.arlt@esd-electronics.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) { ...

2010-05-0674xx_7xx: CPCI750: Add ECC support on esd CPCI-CPU/750 boardReinhard Arlt
Add ECC support for DDR RAM for MV64360 on esd CPCI-CPU/750 board. This patch also adds the "pldver" command to display the CPLD revision. Signed-off-by: Reinhard Arlt <reinhard.arlt@esd.eu> Signed-off-by: Stefan Roese <sr@denx.de>

2008-06-12Change initdram() return type to phys_size_tBecky Bruce
This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
2008-05-21Big white-space cleanup.Wolfgang Denk
This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>
