2011-06-28cortex_m3: add auto maskisrv0.5.0-rc1Spencer Oliver
This patch extends the cortex_m3 maskisr command by a new option 'auto'. The 'auto' option handles interrupts during stepping in a way they are processed but don't disturb the program flow during debugging. Before one had to choose to either enable or disable interrupts. The former steps into interrupt handlers when they trigger. This disturbs the flow during debugging, making it hard to follow some piece of code when interrupts occur often. When interrupts are disabled, the flow isn't disturbed but code relying on interrupt handlers to be processed will stop working. For example a delay function counting the number of timer interrupts will never complete, RTOS task switching will not occur and output I/O queues of interrupt driven I/O will stall or overflow. Using the 'maskisr' command also typically requires gdb hooks to be supplied by the user to switch interrupts off during the step and to enable them again afterward. The new 'auto' option of the 'maskisr' command solves the above problems. When set, the step command allows pending interrupt handlers to be executed before the step, then the step is taken with interrupts disabled and finally interrupts are enabled again. This way interrupt processing stays in the background without disturbing the flow of debugging. No gdb hooks are required. The 'auto' option is the default, since it's believed that handling interrupts in this way is suitable for most users. The principle used for interrupt handling could probably be used for other targets too. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>

2011-06-24Fix load_image for ELF with all p_paddr set to zeroDrasko DRASKOVIC
So far image_load command tries to load ELF binaries to address discovered by reading p_paddr member of a Program header of an ELF segment. However, ELF specifications says for p_paddr : ...Because System V ignores physical addressing for application programs, this member has unspecified contents for executable files and shared objects. ARM ELF specifiaction goes even further, demanding that this member be set to zero, using the p_vaddr as a segment load address. To avoid the cases to wrong addr where p_paddr is zero, we are now using p_vaddr to as a load destination in case that *all* p_paddr == 0. Basically, this patch re-implements the approach present in BDF's elf.c, which is used by GDB also (so that we can be consistent).

to use mips_m4k_write_memory() and mips_m4k_read_memory() to correctly set-up SDRAM, as well as bulk data write, which already handled endianess well. Also added correct endianess manipulation in case of fallback from erroneus bulk write to simple write (to avoid byte swapping two times).
