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>

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>
