2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2016-04-04microblaze: Remove !OF_CONTROL code for timer and interruptMichal Simek
OF_CONTROL is enabled by default that's why this is dead code. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2016-04-04microblaze: Read information about timer/interrupts from DTMichal Simek
Read information about timer and interrupts from DT. This is the first small step to move timer and intc to DM. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2015-02-09microblaze: Remove DEBUG_INT macro and use debug() insteadMichal Simek
Do not use specific macros for debugging. Also remove compilation warning: w+../arch/microblaze/cpu/interrupts.c: In function 'interrupt_handler': w+../arch/microblaze/cpu/interrupts.c:153:2: warning: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'void (*)(void *)' [-Wformat] w+../arch/microblaze/cpu/interrupts.c:153:2: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'void *' [-Wformat] Signed-off-by: Michal Simek <michal.simek@xilinx.com>

Return value to find out if un/registration was succesful. Signed-off-by: Michal Simek <monstr@monstr.eu>

2012-02-23microblaze: avoid interrupt race conditionsStephan Linz
The interrupt acknowledge action have to run after the registered interrupt handler. So we have a chance to bear out the corresponding interrupt request in the corresponding controller hardware. With this reordering, we optain a proper interrupt handling for level triggered interrupt sources -- for example the new axi_timer v1.02.a introduced in ISE 13.2.

2011-01-10microblaze: Disabling interrupt should return 1 if was enabledMichal Simek
Microblaze implement enable/disable interrupts through MSR that's why disable_interrupts function should return 1 when interrupt was enabled. Return 0 when interrupt was disabled.

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: 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>

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>
