powerpc/lib: fix unsafe register handling in wait_ticks

2013-04-10T14:31:02Z

If watchdog is enabled, the arch/powerpc/lib/ticks.S::wait_ticks() function calls the function specified by the WATCHDOG_RESET macro. The wait_ticks function depends on the registers r0, r6 and r7 being preserved however that is not guaranteed, e.g. if the reset function is a C function this will probably overwrite r0 and cause an endless loop. The following patch changes to using r14+r15 instead of r6+r7 (to resemble what would have been generated by a C compiler) and saves all necessary registers on the stack. The patch has been tested on a custom MPC5125 based machine using the 512x powerpc architecture. Signed-off-by: Mats Karrman Cc: Wolfgang Denk Acked-by: Joakim Tjernlund Tested-by: Stefan Roese

ppc: Enable generic board support

Declare watchdog functions in watchdog.h

2013-03-15T20:13:59Z

These functions are only available for powerpc and are not declared in a header file. We want to use the rest function in two places (board_f and board_r), so declare the functions in watchdog.h. Signed-off-by: Simon Glass

Replace __bss_end with bss_end

2013-03-15T20:13:54Z

Note this is a tree-wide change affecting multiple architectures. At present we use __bss_start, but mostly __bss_end__. This seems inconsistent and in a number of places __bss_end is used instead. Change to use __bss_end for the BSS end symbol throughout U-Boot. This makes it possible to use the asm-generic/sections.h file on all archs. Signed-off-by: Simon Glass

Clean up libfdt.h includes

2013-02-09T03:32:38Z

The libfdt.h file is the definition file for libfdt. It is unnecessary to include other fdt header files (the necessary ones are pulled in by libfdt.h). Signed-off-by: Gerald Van Baren Acked-by: Simon Glass Acked-by: Stefan Roese

treewide: include libfdt_env.h before fdt.h

2013-02-08T01:38:55Z

and, if including libfdt.h which includes libfdt_env.h in the correct order, don't include fdt.h before libfdt.h. this is needed to get the fdt type definitions set from the project environment before fdt.h uses them. Signed-off-by: Kim Phillips Cc: Jerry Van Baren
