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.

2010-10-18Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk
The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

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) { ...

2010-04-16microblaze: Consolidate cache codeMichal Simek
Merge cpu and lib cache code. Flush cache before disabling. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-04-16microblaze: Fix interrupt handler codeMichal Simek
It is better to read ivr and react on it than do long parsing from two regs. Interrupt controller returs actual irq number. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-04-16microblaze: Move FSL initialization to board.cMichal Simek
Move FSL out of interrupt controller. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-04-16microblaze: Move timer initialization to board.cMichal Simek
I would like to handle case where system doesn't contain intc that's why I need timer initialization out of intc code. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-04-16microblaze: Fix irq.S codeMichal Simek
It is ancient code. There is possible to save several instructions just if we use offset instead of addik Signed-off-by: Michal Simek <monstr@monstr.eu>
